FIRM SIZE DISTRIBUTION: DO FINANCIAL CONSTRAINTS EXPLAIN IT ALL? EVIDENCE FROM SURVEY DATA Paolo Angelini (Bank of Italy, Economic Research Department) Andrea Generale (Bank of Italy, Economic Research Department) We address the question in the title using survey-based measures of financial constraints, as opposed to the proxies typically used in the literature. We find that in our dataset of Italian firms, those declaring to be financially constrained are smaller and younger than the others. However, the size distribution of non constrained firms is significantly skewed, and virtually overlaps with the FSD for the entire sample. Similar conclusions are drawn from the analysis of a large subsample comprising very young firms. These results are broadly confirmed using several non survey-based proxies of financial constraints, and over a second large sample including firms from OECD and non OECD countries. The analysis of the latter dataset suggests that financial constraints are a relatively more serious problem in developing countries. We conclude that financial constraints cannot be the main determinant of the FSD evolution over time, especially in financially developed economies. Keywords: firm size distribution, financial constraints. JEL: L11 Date: 2005-06 URL: http://d.repec.org/n?u=RePEc:bdi:wptemi:td_549_05&r=all 2. Proprieta', controllo e trasferimenti nelle imprese italiane. Cosa e' cambiato nel decennio 1993-2003? Silvia Giacomelli (Banca d'Italia) Sandro Trento (Banca d'Italia) This paper analyzes the results of two surveys conducted by the Bank of Italy in 2003, respectively among 1,900 and 500 Italian firms, on ownership structures, control and control transfers of non-listed firms, building upon similar surveys carried on in 1993. The aim of the research is to assess the degree and the directions of changes in control patterns of industrial firms in Italy. The data show that ownership concentration, as measured by various indicators, is high and that direct family control of firms is prevalent. Separation between ownership and control is limited. Financial institutions (including private equity) rarely own capital stakes or play a role in controlling non-financial firms. Ownership of a firm by another firm is widespread, especially for bigger firms; ultimate owners are usually families. Foreign ownership and control of Italian firms is growing. Overall, relatively small changes in the patterns of ownership and control have occurred over the decade (1993-2003). The market for corporate control has not developed significantly; it remains based on personal contacts. Financial institutions do not play a relevant role in it; transactions are usually mediated by legal and accounting professionals. Many firms will deal with generational transfers of control in the near future.

QUOTA DEI PROFITTI E REDDITIVITA DEL CAPITALE IN ITALIA: UN TENTATIVO DI INTERPRETAZIONE Roberto Torrini (BANK OF ITALY) Profit share in Italy has been growing between the mid-1970s and the mid-1990s, remaining stable at historically high levels since than. After dropping in the first half of the 1970s, owing to an unprecedented rapid rise in wages, profit share started to recover. The rise during the 1980s involved the entire business sector and was part of this recovery process. During the 1990s profit share continued to grow on average, but with large cross- sector differences. Profit share in manufacturing, which is more exposed to international competition, declined, together with the returns on capital stock, but increased in the rest of the business sector. We show that the better performance of the non- manufacturing business sector is mainly due to the industries most affected by the large-scale privatisations and restructuring of State-owned companies that began in the first half of the 1990s. They led to a rapid growth in total factor productivity and a deceleration in wages, without a major impact on the market power of privatised companies. On the contrary, profitability in the manufacturing sector was negatively affected by a loss of competitiveness in international markets.

HIRING INCENTIVES AND LABOUR FORCE PARTICIPATION IN ITALY Piero Cipollone (BANK OF ITALY) Corrado Di Maria (Tilburg University) Anita Guelfi (Confindustria) A long-standing economic tradition maintains that labour supply reacts to market tightness; its sensitivity to job quality has received less attention. If firms hire workers with both temporary and open-end contracts, does participation increase when more permanent jobs are available? We investigate this relationship within a policy evaluation framework; in particular, we examine how labour supply reacted in Italy to a recent subsidy in favour of open-end contracts. This subsidy increased labour force participation by 1.4% in 2001 and 2.1% in 2002. This increase was concentrated on males aged 35-54, with a low or at most a secondary schooling level, and might be due to the choice to leave undegraound economy.

Contracting Out Public Service Provision to Not-For-Profit Firms John Bennett Elisabetta Iossa In an incomplete contract setting, we analyze the contracting out of public service provision, comparing the performance of for- profit and not-for-profit private firms. Two institutional arrangements are considered, control rights lying either with the firm as under the UK’s Private Finance Initiative (PFI) or the government (as under traditional procurement). We derive the conditions under which provision by not-for-profit firms leads to greater investment and social benefit than provision by for profit firms. The role played by the non-distribution constraint in not-for profit firms and the nature of the investment are emphasized.

Division of Labour and Directed Production Marisa Ratto Wendelin Schnedler We examine a situation where efforts on different tasks positively affect production but are not separately verifiable and where the manager (principal) and the worker (agent) have different ideas about how production should be carried out: agents prefer a less efficient way of production. We show that by dividing labour (assigning tasks to different agents and verifying that agents do not carry out tasks to which they are not assigned), it is possible for the principal to implement the efficient way of production. Colluding agents can undermine this implementation. However, if agents have different abilities, collusion can be prevented by a specific assignment of agents tasks.

Does external trade promote financial development? Yongfu Huang Jonathan Temple Several recent papers have argued that trade and financial development may be linked, either for political economy reasons, or because foreign competition and exposure to shocks lead to changes in the demand for external finance. In this paper we use the cross-country and time-series variation in openness to study the relationship between trade and finance in more detail. Our results suggest that increases in goods market openness are typically followed by sustained increases in financial depth. Keywords: openness, trade, financial development.

La guerra justa y el fin de la historieta(un manifiesto neomoderno) Carlos Escude If all cultures are morally equivalent, then all individuals are not essentially endowed with the same human rights, because some cultures award some men more rights than are allotted to other men and women. If, on the other hand, all men and women are endowed with the same human rights, then all cultures are not morally equivalent, because cultures that acknowledge that "all men are created equal" are ethically superior to those that do not. These two statements are mutually contradictory and cannot both be true. Moreover, there is a natural conflict between them, leading to inevitable intra and inter-civilizational clashes. Relativism will confront evolutionism and hierarchical theocracy will confront secularized republicanism. This essay takes sides and argues that cultural superiority can be asserted on two different levels: moral and epistemological. A culture that acknowledges a set of universal human rights is superior to one that does not, even if it often deviates from these very norms. A culture capable of delving into nature increasing life expectancy through scientific discovery is superior to one that cannot. Furthermore, waging war to defend a superior culture is a moral imperative. Date: 2005-07 URL: http://d.repec.org/n?u=RePEc:cem:doctra:295&r=all 9. Housing Price Dispersion: an empirical investigation Charles Ka Yui Leung Youngman Chun Fai Leong Siu Kei Wong The efficiency of a market is challenged when price dispersion occurs. Previous studies focused on non-durable consumption goods. This study extends the analysis to the case of residential property, whose transactions are dominated by a second-hand market with many potential buyers and sellers. We demonstrate that housing price dispersion exists, and the degree of dispersion changes systematically with some macroeconomic factors, though the second and the third moment of the price distribution react differently to the macroeconomic variables. Some directions for future research are suggested.

Forced information disclosure and the fallacy of transparency in markets Cason, Timothy N. Plott, Charles R. A theory advanced in regulatory hearings holds that market performance will be improved if one side of the market is forced to publicly reveal preferences. For example, wholesale electricity producers claim that retail electricity consumers would pay lower prices if wholesale public utility demand is disclosed to producers. Experimental markets studied here featured decentralized, privately negotiated contracts, typical of the wholesale electricity markets. Two conclusions emerge: (i) such markets generally converge to the competitive equilibrium and (ii) forced disclosure works to the disadvantage of the disclosing side. Information disclosure would result in higher wholesale and thus higher retail electricity prices Date: 2004-06 URL: http://d.repec.org/n?u=RePEc:clt:sswopa:1202&r=all 11. Costo de Uso del capital en Colombia: 1997-2003. Leonardo RHENALS ROJAS El documento analiza la evolucion del costo de uso del capital en el periodo 1997 – 2003 en Colombia. A diferencia de los trabajos anteriores se construye una serie del costo de uso del capital a partir de la informacion suministrada por las empresas a la Superintendencia de Sociedades, lo cual evita los errores generados por la utilizacion de variables macroeconomicas agregadas. Durante los ultimos siete anos las tasas de interes y la inflacion se han reducido drasticamente luego de la crisis de finales de los noventa, lo cual ha repercutido sobre el costo de uso del capital en Colombia. Por otra parte, las tasas impositivas han permanecido relativamente constantes, a pesar de las numerosas reformas tributarias las cuales han estado mas orientadas a aumentar la base gravable. Estos dos factores afectan las decisiones de inversion y financiamiento por parte de las empresas lo cual se ve reflejado en el crecimiento economico de mediano y largo plazo. Durante el periodo de estudio el costo de uso se ha reducido en poco mas de un tercio desde su nivel en 1997, sin embargo en terminos reales sigue siendo alto. Medidas adoptadas recientemente para estimular la inversion via descuento de inversiones en activos productivos tendrian un impacto limitado sobre el costo de uso del capital con respecto a medidas de politica monetaria tendientes a reducir las tasas de interes y la inflacion.

Maria Eugenia PINTO BORREGO Andres VERGARA BALLEN Yilberto LAHUERTA PERCIPIANO Este documento incluye un ejercicio de valoracion de los costos tanto directos como indirectos que la violencia armada ha impuesto a la economia nacional entre los anos 1999 y 2003. Entre los costos considerados se cuentan aquellos generados por el dano a infraestructura energetica, vial y aeroportuaria, por fenomenos como el secuestro, al extorsion, el narcotrafico, el desplazamiento forzado, el uso de minas antipersonal, asi como el pago de indemnizaciones a victimas, entre otros. Como resultado del ejercicio se estima que los costos de la violencia armada en Colombia durante 1999-2003 se acercan a los $16,5 billones de 2003. La mayor parte de los costos calculados, $14,6 Billones, corresponden a la categoria de costos directos (88.3% del total de costos). Por su parte, los costos indirectos, ascendieron a $1,9 Billones, equivalentes al 11,7% del total. Estos costos equivalen al 7,4% del PIB de 2003, a 2,7 veces el deficit del sector publico consolidado de 2003; ademas, es 2,1 veces el Presupuesto de Inversion de la Nacion y el 14,1% de la deuda del sector publico no financiero (neto de activos).

El caso de NAFTA y los TLC con Chile y Singapur. Alejandra RANGEL Catalina DELGADO Jorge CEPEDA German MUNOZ Debido a la importancia de los servicios en la produccion, el empleo y el comercio internacional, la eliminacion de las barreras al comercio de este sector y su consecuente liberalizacion, se ha convertido en uno de los principales objetivos de las negociaciones comerciales llevadas a cabo en los ultimos anos. Dado que Colombia se encuentra actualmente impulsando la negociacion de un tratado bilateral con Estados Unidos, resulta conveniente examinar los ultimos tratadosfirmados por este pais a fin de establecer el grado de liberalizacion de los paises en el sector servicios. Para esto, se requiere una metodologia que tenga en cuenta que las barreras al comercio en este sector no son aranceles -como en el comercio de bienes- sino regulaciones internas de los paises. En este documento, se empleo el tradicional indice de Hoekman para comparar algunos acuerdos firmados por Estados Unidos, el TLCAN con Mexico y Canada y los TLC con Chile y Singapur. La metodologia muestra que, en promedio, el tratado menos liberal es el firmado entre EEUU y Chile, y el mas abierto es el TLCAN. Sin embargo, el grado de liberalizacion de Estados Unidos cambia en cada uno de los tratados, lo mismo sucede por sectores.

Letty Margarita BOHORQUEZ Cesar Augusto MERCHAN Desde la segunda mitad de los noventa el desempleo en Colombia adquirio magnitudes preocupantes (alrededor del 18%) y aunque ha habido cierta tendencia a la baja, o al menos a su estabilizacion, el fenomeno sigue siendo alarmante con respecto a la situacion de los demas paises de la region y frente al propio historial del pais. Para atenuar el problema, el gobierno ha intensificado sus esfuerzos en cuatro componentes directos utilizados tipicamente para enfrentar el fenomeno: a) reentrenamiento y capacitacion laboral desarrollado principalmente por el SENA y el subprograma Jovenes en Accion; b) intermediacion laboral, tambien a cargo del SENA y de diferentes empresas privadas; c) desarrollo empresarial, con los diversos apoyos a las empresas, y d) programas de empleo publico como el subpograma Empleo en Accion. Estos esfuerzos han sido insuficientes para contrarrestar el desempleo y han llevado al Gobierno Nacional a plantear la posibilidad, a nivel normativo, de crear un subsidio al salario (tambien denominado subsidio al empleo). Dicha opcion ya se ha aplicado tanto en paises desarrollados como en algunos de Latinoamerica, con resultados y recomendaciones de politica diversos. Incluso en Colombia se han hecho intentos pero con resultados poco favorables. Explorar la viabilidad tecnica de un subsidio al salario, asi como su pertinencia y forma de aplicacion en Colombia, es el objetivo de este estudio que se compone de siete secciones. En la siguiente seccion se describe en breve la gravedad del desempleo del pais. Las secciones tercera y cuarta resumen tanto el marco teorico como las caracteristicas generales de los programas de subsidio al salario, mientras que la quinta describe algunas experiencias internacionales. En la seccion seis se esboza la estructura basica de un subsidio al salario para Colombia, para finalizar en las acostumbradas conclusiones y recomendaciones de politica.

Rudolf HOMMES RODRIGUEZ Claudia Marcela UMANA APONTE. El objetivo de este analisis es plantear metas de crecimiento economico que le permitan a Colombia en el transcurso de 20 anos alcanzar el desarrollo suficiente para duplicar el Producto Interno Bruto (PIB) per capita del pais. Asi mismo, se busca plantear metas de politica social que mejoren el bienestar de la poblacion colombiana. Para lograr estos objetivos se analizo el proceso de desarrollo de paises que rapida y establemente alcanzaron altos niveles de PIB per capita en el mismo periodo de tiempo o menos. Basicamente el analisis se centro en los paises asiaticos y especialmente en el desarrollo de Corea del Sur.

Daniel VAUGHAN CARO En este documento se presenta una revision critica de la literatura acerca de los efectos y cuantificacion de las barreras no arancelarias, dentro del marco de las negociaciones de un tratado de libre comercio con Estados Unidos. Para esto, se realiza una revision de la literatura teorica y empirica, y una revision historica de la posicion de Estados Unidos y Colombia. Por ultimo, se utiliza un modelo de equilibrio general computable para simular la eliminacion de las barreras arancelarias y no arancelarias entre Estados Unidos y Colombia. Se concluye que los modelos de equilibrio general computable sobre estiman los efectos de las BNAs debido principalmente a limitaciones de la metodologia utilizada para cuantificar los efectos de las mismas y de los supuestos utilizados para modelar la demanda de importaciones.

Catalina DELGADO GONZALEZ Este trabajo recurre al marco de analisis sobre los sistemas publicos de educacion y pensiones de Boldrin y Montes (2002), basado en un modelo de generaciones traslapadas con produccion y acumulacion de capital fisico y humano. Partiendo de este modelo teorico, se presenta un ejercicio empirico para el caso colombiano, en el que se busca establecer hasta que punto las transferencias intergeneracionales inducidas por los sistemas de educacion y pensiones vigentes, replican las condiciones de eficiencia que plantea el modelo. Con base en informacion micro de la Encuesta de Calidad de Vida y cifras agregadas del Presupuesto para 2003, se realizaron las estimaciones, que muestran que en Colombia no solo no existen los mecanismos de transferencias intergeneracionales que permiten asignaciones eficientes, sino tambien que existen asimetrias de genero que hacen que invertir en capital humano sea mas rentable para los hombres.

Javier Hernando OSORIO GONZALEZ Juliana MARTINEZ CUELLAR Tomas RODRIGUEZ BARRAQUER. El modelo DNPension es un modelo contable discreto, basado en un componente demografico que simula el comportamiento del sistema pensional colombiano a un horizonte de 100 anos. La version 4.0 cuenta con la versatilidad necesaria para simular practicamente cualquier cambio en los parametros fundamentales que caracterizan un sistema pensional, en un lapso de tiempo considerablemente pequeno. El modelo se viene desarrollando de una manera continua desde 1999 y esta basado en la idea original de Juan Carlos Parra Osorio. El objetivo de este documento es explicar el funcionamiento del modelo, comenzado por un analisis general de los datos que lo alimentan y una descripcion de su funcionamiento. A manera de ilustracion, se muestran los resultados de dos ejercicios. El primero cuantifica el deficit del ISS y Cajanal. El segundo evalua diferentes escenarios del ejercicio de pilares, donde el primer pilar varia entre 1, 2, 3 y 4 SMLV. Finalmente se cierra este documento con un informe de la evolucion del modelo, no solo en materia de programacion sino tambien en el tema de la calidad de la informacion que utiliza.

Alfredo SARMIENTO Jorge Ivan GONZALEZ Roberto ANGULO Francisco ESPINOSA Este articulo explica el significado conceptual, la medicion y la importancia que tiene en la actual coyuntura colombiana, la Poverty Equivalent Growth Rate (PEGR) de Kakwani, Khandker y Son ( 2004). El analisis de los datos de la experiencia reciente muestra que en la mayor parte de los anos el crecimiento tiende a no ser a favor de los pobres. De manera que se hace necesario un esfuerzo explicito a favor de politicas de crecimiento que favorezcan la distribucion. En particular, estrategias dirigidas a mejorar el acceso a activos como tierra, capital, credito y educacion para los mas pobres. Las politicas distributivas convierten el crecimiento en un crecimiento a favor de los pobres.

COMPARACION DEL GASTO DE LOS HOGARES ENTRE 1997 Y 2003, SEGUN RESULTADOS DE LAS ENCUESTAS DE CALIDAD DE VIDA: MAGNITUD, COMPOSICION Y DISTRI Manuel Ramirez Andres Zambrano Manuel Munoz El proposito de este estudio es analizar el cambio en magnitud, composicion y distribucion del gasto de los hogares en los anos 1997 y 2003, usando las encuestas de calidad de vida. Este analisis encuentra una gran disminucion del gasto per capita ( 23.9%), especialmente en zonas urbanas y regiones mas adelantadas, reflejo de la crisis economica que golpea al pais desde 1998. Este decrecimiento desigual genero una mejor distribucion en el 2003 y ocasiono un cambio en la estructura de gastos, llevando a un importante crecimiento de la proporcion de los gastos en alimentos y una disminucion de los gastos de educacion y salud. En el documento se utilizo estadistica descriptiva, discriminando por quintiles de cada region y clase ( urbano rural). Posteriormente se realizaron estimaciones parametricas y no parametricas de las curvas de Engel, para cada rubro, con el fin de identificar su naturaleza.

Biased selection within the social health insurance market in Colombia Ramon Castano Andres Zambrano Reducing the impact of insurance market failures with regulations such as community-rated premiums, standardized benefit packages and open enrolment, yield limited impact because they create room for selection bias. The Colombian social health insurance system started a market approach in 1993 on the expectation to improve performance of preexisting monopolistic insurance funds by exposing them to competition by new entrants. It is hypothesized that market failures would lead to biased selection favoring new entrants. Two household surveys are analyzed using Self-reported health status and the presence of chronic conditions as indicators of prospective risk of enrolees. Biased selection is found to take place, leading to adverse selection among incumbents, and favorable selection among new entrants. This pattern is observed in 1997 and worsens in 2003. Although the two incumbents analyzed are public organizations, and their size dropped substantially between these two years, fiscal implications in terms of government bailouts are analyzed.

Estructuras organizacionales, esquemas salariales y calidad educativa en America Latina: un estudio comparativo de los casos de Chile, Mexic Carolina Alban Las deficiencias que registran los diferentes paises de America Latina en los indicadores relacionados con el rendimiento escolar y la calidad educativa han sido un tema recurrente en la agenda politica de los gobiernos de la region durante las ultimas decadas. Diferentes estudios sugieren la incidencia de variables como la razon maestro/alumno, el gasto per capita y la formacion docente, entre otros. Sin embargo, se ha explorado muy poco la influencia de variables como la estructura organizacional, los sistemas de evaluacion, los esquemas salariales y los incentivos, entre otros. Este trabajo pretende realizar una caracterizacion del desarrollo de estos aspectos para cuatro paises de America Latina: Chile, Mexico, Peru y Uruguay, en el marco de las reformas educativas emprendidas en los noventas. Adicionalmente se presenta un analisis de los principales resultados obtenidos hasta el momento, discriminados en dos tipos: la evolucion de los salarios docentes y el mejoramiento en los resultados academicos de los estudiantes.

Subsidios cruzados: el caso del sector postal Luis Fernando Gamboa Nino Leslie Bravo Chew The document seeks to evaluate the existence of cross subsidization between the regulated and competitive parts of the postal sector. We analyze the incentive to make cross subsidization when prices are regulated by Ramsey Pricing or by Global Price Cap. By means of a linear demand function, we found cross subsidies constrain and distort the liberalization of the sector and it is important to avoid them for the competition.

Ownership and Control in Colombian Corporations Carlos Pombo Luis H Gutierrez Rodrigo Taborda We study the separation of ownership and control for an average of 140 listed non-financial Corporations in Colombia during the 1996-2002 period. Breaking the sample according to their listing status and economic activity, voting rights are greater than cash flow rights because of the presence of indirect ownership across firms that belong mainly to pyramidal and cross share holdings. The study sample also includes an important set of non-affiliated firms. Ownership statistics show high concentration for the top- four largest voting blocks similar to the levels observed in continental Europe, although the largest stake has on average 20% lower voting rights than the average observed in that region. Finally, holding investment and trust funds play a central role as the holdings’ ultimate controllers.

MARKET ACCESS IN THE WESTERN HEMISPHERE: IMPLICATIONS FOR THE ANDEAN Ricardo Arguello Ernesto Valenzuela This study contributes to the economic assessment of further trade liberalization in the Western Hemisphere over the Andean Community member countries. The most significant trade liberalization scenarios are identified and simulated by means of the standard, constant returns to scale, GTAP model. The main results show little coincidence in the direction of welfare changes for the Andean countries under the four scenarios analyzed. In a very simplified way, further trade liberalization brings welfare losses for Colombia, Peru, and Ecuador-Bolivia, while Venezuela experiences gains under the implementation of the Free Trade Area of the Americas and loses under the implementation of Free Trade Agreements of the other Andean countries with the U.S. Terms of trade effects play a significant role in determining this outcome. In general, they move against these economies, with the notorious exception of Venezuela. It appears that Andean countries have benefited in the past from trade deviation from other regions as they entered into preferential trade agreements. With the erosion of preferential market access embodied in the scenarios simulated, the increase in competition at the import and export levels tend to adjust the standing of these countries, bringing in new challenges for them.

Adjustment of the WACC with Subsidized Debt in the Presence of Corporate Taxes: the N-Period Case Ignacio Velez-Pareja Joseph Tham Viviana Fernandez Abstract: In the standard Weighted Average Cost of Capital (WACC) applied to the free cash flow (FCF), we assume that the cost of debt is the market, unsubsidized rate. With debt at the market rate and perfect capital markets, debt only creates value in the presence of taxes through the tax shield. In some cases, the firm may be able to obtain a loan at a rate that is below the market rate. In a previous work, we showed how to adjust the WACC in the presence of a subsidy and no taxes. There, we showed that plugging the lower (subsidized) cost of debt into the WACC formula is not the correct approach to measuring the value creation due to the subsidy. With subsidized debt and taxes, there would be a benefit to debt financing, and the unleveraged and leveraged values of the cash flows would be unequal. The benefit of lower tax savings are offset by the benefit of the subsidy. These two benefits have to be introduced explicitly. How would we adjust the WACC to take account of the subsidized debt? And how would we adjust the expression for the required return to leveraged equity? In this paper, using a multiple period example we present the adjustments to the WACC with subsidized debt and taxes. We demonstrate the analysis for both the WACC applied to the FCF and the WACC applied to the capital cash flow (CCF). We use the calculation of the Adjusted Present Value, APV, to consider both, the tax savings and the subsidy. We show how all the methods match.

Consistency in Valuation: A Practical Guide Ignacio Velez-Pareja Antonio Burbano Abstract: Practitioners and teachers very easily break some consistency rules when doing or teaching valuation of assets. In this short and simple note we present a practical guide to call the attention upon the most frequent broken consistency rules. They have to do firstly with the consistency in the matching of the cash flows, this is, the free cash flow (FCF), the cash flow to debt (CFD), the cash flow to equity (CFE), the capital cash flow (CCF) and the tax savings or tax shield (TS). Secondly, they have to do with the proper expression for the cost of levered equity, Ke and different formulations for the weighted average cost of capital, WACC, with finite cash flows and perpetuities. Thirdly, they have to do with the consistency between the terminal value and growth for the FCF and the terminal value and growth for the CFE. And finally, the proper determination of the cost of capital either departing from the cost of unlevered equity (Ku) or the cost of levered equity (Ke). We illustrate the consistency using a simple example. In the Appendixes we show some algebraic derivations.

Una nota sobre el calculo del valor con endeudamiento constante Ignacio Velez-Pareja Joseph Tham Es ampliamente conocido que si el endeudamiento es constante en el tiempo, entonces el costo del patrimonio, Ke, y el costo promedio de capital CPPCFCL tambien es constante. En otras palabras, no es correcto usar un CPPCFCL constante para descontar el flujo de caja libre FCL, si el endeudamiento cambia en el tiempo. Sin embargo, es muy comun, tanto en la practica, como en la literatura, encontrar analistas y autores que de manera inconsistente usan un CPPCFCL para descontar el FCL aunque el endeudamiento no sea constante. En esta nota pedagogica utilizamos un ejemplo numerico sencillo para ilustrar como modelar los flujos de caja que sean consistentes con ese endeudamiento. En el ejemplo se verifica la consistencia con dos principios basicos: la conservacion de los flujos de caja y la conservacion de los valores.

Historia monetaria de Colombia en el siglo XX: grandes tendencias y episodios relevantes. Fabio Sanchez Andres Fernandez Armando Armenta El objetivo general de la investigacion es analizar la evolucion, determinantes y efectos del dinero a traves del siglo XX en Colombia. La investigacion se concentra con mayor detalle despues de 1923 ano de la fundacion del Banco de la Republica en 1923, pues la informacion es mejor y mas abundante. Un ejemplo son las Actas de la Junta Directiva del Banco. El trabajo examina las decisiones de politica monetaria bajo los distintos arreglos cambiarios e institucionales que tuvo el pais: el de Patron Oro, tasa de cambio fija, crawling peg, el regimen de bandas cambiarias y de flotacion, estos dos ultimos bajo un marco de independencia del Emisor. El analisis de la evolucion del crecimiento del dinero durante el siglo XX muestra que su principal determinante fue el sector externo y, –en menor medida– los desequilibrios del sector publico. En adicion a los determinantes mencionados, la politica monetaria se utilizo en forma contraciclica. Asi, a pesar de que en el largo plazo no existe una relacion sistematica entre el crecimiento del dinero y cambios en la actividad real –como si con el nivel de precios–, la autoridad si exploto en el corto plazo la relacion positiva entre estas dos variables. En forma paralela a los movimientos del dinero, el Banco de la Republica aumento su presencia institucional y economica ademas de mejorar y consolidar sus instrumentos de politica. El documento presenta, por una parte, un vision general del los movimientos del dinero a lo largo del siglo, y por otro, examina algunos de los episodios historicos monetarios relevantes. El analisis documenta el proceso de toma de decisiones por parte de la autoridad monetaria a partir de las fuentes primarias narrativas y de la recopilacion de los indicadores economicos disponibles en cada momento historico.

El censo nacional de poblacion: una comparacion de metodologias mediante simulaciones de Monte Carlo Christian Jaramillo Ana Maria Ibanez Bajo una fuerte polemica, Colombia se prepara para aplicar un nuevo censo de poblacion. La adopcion de una enumeracion continua constituye una de las principales modificaciones y es el centro de la polemica suscitada. Numerosas dudas han surgido en torno al nuevo diseno y un interrogante particular es la efectividad de un censo continuo dado la alta movilidad de la poblacion colombiana debido al fenomeno del desplazamiento forzado. El objetivo de este articulo es evaluar la exactitud de la informacion obtenida y su degradacion, es decir, la perdida de exactitud en el conteo de la poblacion colombiana a traves el tiempo para los dos tipos de censos: censo tradicional y censo continuo. La comparacion, basada en simulaciones de Monte Carlo, indica que la diferencia en la exactitud y degradacion de la informacion entre los dos tipos de censo, aunque estadisticamente significativa, es minima.

Conflicto, estado y descentralizacion: del progreso social a la disputa armada por el control local.1974-2002 Fabio Sanchez Mario Chacon El objetivo de este trabajo es determinar las variables que explican la actividad armada de los grupos irregulares desde mediados de los anos setenta y establecer las posibles causas de expansion hasta el ano 2002, teniendo en cuenta particularmente el papel de la descentralizacion entendida coma la mayor autonomia politica, presupuestal y administrativa de los gobiernos locales. En los ultimos treinta anos el pais experimento profundos cambios a nivel economico, social e institucional. No solo se consolido el proceso de urbanizacion a la vez que disminuyo la participacion del sector agropecuario en la produccion nacional sino que se profundizo fuertemente el proceso de descentralizacion desde mediados de los anos ochenta. El presente trabajo sostiene que la descentralizacion traslado el conflicto a una disputa por el poder local, lo que se manifiesta en el uso de la violencia ya sea para apropiarse de los bienes y recursos publicos, para influenciar los resultados politicos y electorales de conveniencia para los grupos irregulares y/o para consolidar su dominio territorial desde lo local. El analisis de la actividad temprana (1974-1982) de los grupos guerrilleros muestra que ella esta explicada en mayor medida por variables socioeconomicas (pobreza, desigualdad). Sin embargo, su evolucion desde mediados de los ochenta esta ligada al proceso de descentralizacion el cual creo incentivos a los grupos irregulares para el dominio de lo local a traves del uso de la violencia. Dada la debilidad del Estado en lo relativo al monopolio de la fuerza y a la administracion de justicia, se facilito la expansion e intensificacion de la actividad armada de los grupos guerrilleros y de las autodefensas ilegales. Los distintos resultados estadisticos y econometricos revelan un nexo fuerte entre la intensificacion de la accion armada y la mayor independencia politica y fortaleza fiscal de los gobiernos locales. Esto trabajo conto con nuevos datos historicos sobre el conflicto e informacion economica, fiscal, social y politica a nivel municipal. Se utilizo la informacion recientemente recopilada a nivel municipal por el IEPRI sobre la actividad y acciones de armadas de los distintos grupos guerrilleros (FARC, ELN. M-19) para el periodo 1974-1982 y las bases de datos municipales de la Fundacion Social, Departamento Nacional de Planeacion y Presidencia de la Republica sobre acciones y ataques de grupos guerrilleros, de autodefensas y de delincuentes para el periodo 1985 a 2002.

Jaramillo H. Individuals frequently contribute their resources voluntarily to provide public goods. This paper models the manner in which the linkage between members in a community influences the likelihood of such actions through spontaneous activism in networks. The model I use abstracts from the issue of free-riding behavior by means of small deviations from standard preferences. Instead, it concentrates on the communication aspect of provision through collective action. The solution concept is Nash equilibrium. I find that the likelihood of efficient provision of a discrete public good in random social networks increases very rapidly for parameter values where the network experiences a phase transition and large-scale decentralized activism becomes feasible. As a result, the model shows that successful coordination may be more readily achieved the larger the population is, provided its members are sufficiently connected. In contrast with previous results in the literature, this results holds even as the size of the population increases without bound, and it is consistent with the existence of largescale activism in large populations.

Civil conflict and forced migration: the micro determinantes and the welfare losses of displacement in Colombia Ana Maria Ibanez Carlos Eduardo Velez During the last decade, forced internal displacement in Colombia has been a growing phenomenon closely linked to the escalation of the internal armed conflict - particularly in rural areas. The displacement problem has affected nearly every region and vulnerable groups of the population. Two emerging policy questions are whether the magnitude of the response to this problem has been proportional to its size and to what extent the instruments chosen are the most adequate to address it. The purpose of this paper is twofold. First, to identify the determinants of displacement behavior and to compare these findings with standard migration literature. Second, to estimate the burden or welfare losses of displacement. Empirical evidence shows that the welfare loss of displacement is considerable and amount to 37 percent of the net present value of rural lifetime aggregate consumption for the average household. This loss is estimated for each household with a method that derives welfare changes from behavioral model estimates – widely used in environmental economics. Our empirical findings also show that the level of violence at the origin site is not only the dominant factor of displacement behavior, but also that in a violent environment other migration determinants have the opposite effect, relative to the one expected by the migration literature in a non-violent context. That is, the violent environment modifies the migration incentives for risk aversion, access to information, the planning horizon, and location-specific assets – human and non-human.

Marc Hofstetter En 1999 la Corte Constitucional determino que los incrementos en el salario minimo no debian hacerse por debajo de la inflacion pasada. En este articulo exploramos el impacto de esta decision sobre la efectividad de la politica monetaria. En el marco de un modelo macroeconomico sencillo, se muestra que obligar a los agentes a ajustar el salario teniendo en cuenta los precios pasados, implica que la politica monetaria tiene un mayor efecto sobre la actividad real y genera una persistencia mas alta de la inflacion. Estos resultados se cumplen aun bajo los supuestos clasicos mas tradicionales: expectativas racionales, perfecta credibilidad y ajustes sincronizados de los precios.

National, departmental and municipal rural agricultural land distribution in Colombia: analyzing the web of inequality, poverty and violence Norman Offstein Recent literature points to a relationship between inequality, economic growth and socio-economic variables. In order to continue to research the relationship between these factors and inequality in Colombia, it is essential to construct a precise measure of rural land distribution. This paper presents calculations of rural land size and land value Gini coefficients for Colombia at the national, departmental and municipal levels using approximately 2.5 million registries of plot level data supplied by the Instituto Geografico Agustin Codazzi. In general, value Ginis, where value controls for land quality and improvements, are lower than plot size Ginis, and even after meticulous filtration anomalies remain in the data. Additionally, the relationship between the Gini coefficients and municipal level variables are analyzed to consider the relation between inequality, poverty, rurality and other municipal characteristics. Lastly, earlier results relating Gini to violence are reconsidered. After controlling for other factors, distribution does not explain significantly violence.

Determinants, effects and costs of domestic violence Rocio Ribero Fabio Sanchez This paper analyzes the determinants, effects and costs of domestic violence (DV) against women and children in Colombia. The most relevant factors that explain the occurrence of DV in a household are suffering from DV as a child and living with someone that frequently and excessively consumes alcohol. DV against women increases their probability of unemployment by 6.4 percentage points, lowers their earnings by approximately 40% and worsens their health. DV against children negatively affects their health, school attendance and academic attainment. It is estimated that at least 4.2% of Colombian GDP is lost due to indirect costs of DV.

Posibilidades y limitantes de un cambio en la productividad de los sectores colombianos: textiles-confecciones, avicola- porcicola, siderurgi Juan Carlos Echeverry Monica Hernandez Tradicionalmente la productividad en Colombia se ha estudiado a partir de metodologias econometricas y rankings internacionales basados en encuestas de percepcion. A pesar de que este tipo de acercamientos son interesantes y necesarios, finalmente son pocas las recomendaciones que se pueden hacer a los sectores industriales y al gobierno respecto a la mejor forma de aumentar la productividad sectorial. La presente investigacion busca proponer una nueva metodologia de estudio de la productividad, basado en un trabajo directo con empresarios a traves grupos de trabajo (focus groups). La metodologia permite “aterrizar” las consideraciones de productividad, identificando no solo los puntos debiles y fuertes que cada gremio considera tener, sino las fortalezas y amenazas de las que ellos mismos pueden no ser conscientes. El principal aporte que brinda el presente estudio es que cada sector industrial presenta una dinamica diferente y que factores que pueden ser benefactores para un sector, resultan ser irrelevantes o incluso perjudiciales para otro. Este tipo de consideraciones deben ser tenidas en cuenta en el momento de formular estrategias para aumentar la productividad y competitividad del pais. Se cuestiona la conveniencia de esquemas como las cadenas productivas en sectores en donde la materia prima resulta ser el eslabon menos productivo, minando la competitividad de los eslabones que se ubican en niveles mas altos de la cadena. El impacto de elementos como la geografia, la planificacion y consistencia de las politicas sectoriales y el tipo de innovacion tecnologica son tratados con enfasis sectorial, lo cual revela la riqueza de este tipo de analisis, y los riesgos de los analisis con cifras demasiado agregadas que desconocen las diferencias entre sectores de la actividad productiva.

Fabio Sanchez Andres Fernandez Armando Armenta. Entre 1938 y 1967, lo cual incluye el periodo de Bretton Woods despues de la Segunda Guerra Mundial, Colombia fijo su tipo de cambio al dolar. A pesar de que el regimen cambiario opero bajo el esquema de fijacion del tipo de cambio, el peso fue devaluado oficialmente en mas de 12% en seis ocasiones. Los episodios de devaluacion fueron complejos, traumaticos, con un alto componente politico e implicaron ajustes macroeconomicos costosos. El acuerdo de Bretton Woods sostenia que los paises podian devaluar sus monedas solo en presencia de desequilibrios fundamentales como resultado, por ejemplo, de caidas estructurales de sus terminos de intercambio. Sin embargo, este trabajo sostiene que los desequilibrios en el mercado monetario fueron determinantes en la explicacion de las crisis cambiarias durante el periodo de cambio fijo. El ensayo esta organizado en tres partes. Primero, se plantea un modelo teorico simple para una economia pequena y abierta con movilidad imperfecta de capitales en el que se puedan analizar las posibles causas de las devaluaciones nominales. En segundo lugar, se emplea un enfoque narrativo para describir las circunstancias economicas que rodearon cada una de las devaluaciones: asi como la revision de evidencia cualitativa de la epoca. Finalmente, se realiza un conjunto de ejercicios econometricos para identificar las variables determinantes de los desequilibrios macroeconomicos que precedieron cada crisis cambiaria. Los resultados muestran que los desajustes externos estuvieron primordialmente asociados con desequilibrios en el mercado monetario. Los movimientos adversos en los terminos de intercambio explican solo una pequena porcion de las crisis cambiarias.

Canales de transmision monetaria: una revision para Colombia Alexander Correa Ospina Los canales de transmision monetaria son los mecanismos mediante los cuales las acciones de politica monetaria influyen sobre las variables macroeconomicas, tales como inflacion y produccion. Un claro entendimiento del funcionamiento de estos canales es de vital importancia para el diseno de la politica monetaria. Los cambios estructurales en la economia pueden alterar los efectos economicos de una medida de politica monetaria. De igual forma, el contexto institucional y politico en el que se implementa determinada politica puede hacer que los efectos de esta medida sean diferentes a los deseados. En este articulo se analizan estas cuestiones, y a traves de un sencillo modelo econometrico se concluye que el banco central de Colombia es un banco que da una mayor importancia relativa a la volatilidad de la inflacion que a la volatilidad de la produccion.

Interacciones sociales y productivas: una aproximacion a la teoria de redes Julian Pineres Ramirez La presente revision teorica analiza la evolucion de los esquemas de interaccion entre los individuos y las organizaciones, a partir de los cambios en los contextos economicos y las complejidades del mercado —que se entienden como la especializacion de la demanda, el creciente cambio del desarrollo tecnologico, el aumento de las exigencias normativas en los mercados internacionales y las redes globales de distribucion, entre otros— y como dichos cambios crean la necesidad de plantear estrategias distintas de desarrollo industrial, para lo cual se introduce el concepto de redes que al analizarse a partir de su naturaleza y tipologia permite encontrar en los ambientes economicos cuatro formas de interaccion entre las organizaciones y los individuos con el proposito de aumentar sus capacidades y por ende su eficiencia y competitividad: redes de cadenas de abastecimiento, conglomerados industriales, redes de emprendimiento y redes de innovacion. Por lo tanto, se denota un cambio en los paradigmas organizacionales que hacen cada vez mas importante el desarrollo de sinergias en torno a una actividad economica que involucra el conocimiento como factor de desarrollo y la innovacion como un proceso constante para mantenerse en el libre juego de la oferta y la demanda.

Aproximacion al analisis de politicas publicas nacionales que pueden incidir en la conformacion y consolidacion de iniciativas en ciencia y Rodrigo Alberto Matta Diaz Myriam Sanchez Mejia Ana Milena Yoshioka Vargas Julian Pineres Ramirez El desarrollo de estrategias industriales tipo cluster, cadenas productivas y redes, y el fomento de la Ciencia, la Tecnologia y la Innovacion (CyT + I) para incrementar las capacidades de una region basadas en el conocimiento, deben tener una coherencia estrategica en el corto, mediano y largo plazo; en los niveles macro, meso y microeconomico. En este sentido, las politicas publicas juegan un papel predominante, puesto que pueden ser facilitadoras de ambientes economicos favorables articulados coherentemente o creadoras de obstaculos para inhibir el desarrollo de los mismos. El presente trabajo parte entonces de la identificacion y analisis de las politicas publicas que podrian incidir en la formacion y puesta en marcha de una plataforma tecnologica e institucional de apoyo a la bioindustria en el Valle del Cauca con el proposito de formar un cluster. El articulo resalta, por lo tanto, los resultados obtenidos en la investigacion «Fundamentos para el desarrollo de politicas publicas y estrategias empresariales dirigidas a la formacion social y productiva del Cluster Bioindustrial del Occidente Colombiano (CBOC)», tomando como base el diseno de una metodologia y su posterior aplicacion, realizando una primera aproximacion en este tipo de analisis, orientados al desarrollo de clusters basados en el conocimiento y la tecnologia (en este caso biotecnologia).

Juan Vianey Gomez Jimenez La necesidad de ser competitivos ha llevado a la gerencia de las empresas a buscar diferentes formas o alternativas de alcanzar la diferenciacion de sus productos y servicios. Atendiendo a las actuales tendencias, las decisiones de diferenciacion han estado basadas en lo que los clientes y ciudadanos consideran importante. Estos, frente a los continuos cambios economicos y sociales al igual que ante la continua presencia de desastres naturales y infermedades de dificil cura, han evolucionado en su forma de pensar y han sentido la necesidad de ser solidarios y coparticipes en la solucion de los variados problemas que afectan a la poblacion mundial, en especial a la poblacion con menos recursos. Junto a este sentir, ha evolucionado la creencia de que las empresas son responsables de algunas de las situaciones que afectan a la comunidad y que su funcion deberia ir por tanto mas alla de la generacion de empleo y la elaboracion de productos de buena calidad, papel que la empresa debiera atender desde unos objetivos institucionales claros, explicitos e integrados en su mision y no a traves de campanas de mercadeo hacia lo social que buscan «responder» al sentimiento de solidaridad de las personas y que finalmente, generan hacia la empresa fidelidad de los clientes y aumento de las ventas, pero que dejan a la comunidad sin verdaderas soluciones que la eduquen para el desarrollo.

Assignment situations with multiple ownership and their games Miquel,Silvia Velzen,Bas van Hamers,Herbert Norde,Henk (Tilburg University, Center for Economic Research) An assignment situation can be considered as a two-sided market consisting of two disjoint sets of objects. A non-negative reward matrix describes the profit if an object of one group is assigned to an object of the other group. Assuming that each object is owned by a different agent, Shapley and Shubik (1972) introduced a class of assignment games arising from these assignment situations. This paper introduces assignment situations with multiple ownership. In these situations each object can be owned by several agents and each agent can participate in the ownership of more than one object. In this paper we study simple assignment games and relaxations that arise from assignment situations with multiple ownership. First, necessary and sufficient conditions are provided for balanced assignment situations with multiple ownership. An assignment situation with multiple ownership is balanced if for any choice of the reward matrix the corresponding simple assignment game is balanced. Second, balancedness results are obtained for relaxations of simple assignment games. JEL: C71 Date: 2005 URL: http://d.repec.org/n?u=RePEc:dgr:kubcen:200578&r=all 55. Nested maximin Latin hypercube designs in two dimensions Husslage,B Dam,E. van Hertog,D. den (Tilburg University, Center for Economic Research) In black box evaluation and optimization Latin hypercube designs play an important role. When dealing with multiple black box functions the need often arises to construct designs for all black boxes jointly, instead of individually. These so-called nested designs consist of two separate designs, one being a subset of the other, and are used to deal with linking parameters and sequential evaluations. In this paper we construct nested maximin designs in two dimensions. We show that different types of grids should be considered when constructing nested designs and discuss how to determine which grid to use best for a specifc computer experiment. In the appendix to this paper maximin distances for different numbers of points are provided; the corresponding nested maximin designs can be found on the website http://www.spacefillingdesigns.nl.

Innovation races: An experimental study on strategic research activities Uwe Cantner Andreas Nicklisch Torsten Weiland In an experimental setting, firms in a duopoly market engage in a patent tournament and compete for profit-enhancing product advancements. The firms generate income by matching exogenously defined demand preferences with an appropriately composed product portfolio of their own. Demand preferences are initially unknown and first need to be revealed by an investigation of the possible product variations. The better firms approximate demand preferences, the higher their profits. In the ensuing innovation race, firms interact through information spillovers resulting from the imperfect appropriability of research successes. In the random period of the experiment, the continuity of the search process is disturbed by an exogenous shock that affects both the supply and demand side and again spurs research competition. Firms may henceforth explore an enlarged product space in attempting to match the equally modified demand preferences. In our analysis, we explore the behavioral regularities of agents who are engaged in innovation activities. As a key element we test to what extend relative economic performance exercises a stimulating effect on the implementation of innovation and imitation strategies.

Causes, consequences, and cures of myopic loss aversion - An experimental investigation Gerlinde Fellner Matthias Sutter Myopic loss aversion (MLA) has been established as one prominent explanation for the equity premium puzzle. In this paper we address two issues related to the effects of MLA on risky investment decisions. First, we assess the relative impact of feedback frequency and investment flexibility (via the investment horizon) on risky investments. Second, given that we observe higher investments with a longer investment horizon, we examine conditions under which investors might endogenously opt for a longer investment horizon in order to avoid the negative effects of MLA on investments. We find in our experimental study that investment flexibility seems to be at least as relevant as feedback frequency for the effects of myopic loss aversion. When subjects are given the choice to opt for a long or short investment horizon, there is no clear preference for either. Yet, if subjects face a default horizon (either long or short), there is rather little switching from the one to the other horizon, showing that a default might work to attenuate the effects of MLA. However, /if/ subjects switch, they are more often willing to switch from the long to the short horizon than vice versa, suggesting a preference for higher investment flexibility.

Economics research in Canada: A long-run assessment of journal publications James B. Davies Matthias Sutter Martin G. Kocher We examine the publications of authors affiliated with an economics research institution in Canada in (i) the Top-10 journals in economics according to journals' impact factors, and ( ii) the /Canadian Journal of Economics/. We consider all publications in the even years from 1980 to 2000. Canadian economists contributed about 5% of publications in the Top-10 journals and about 55% of publications in the /Canadian Journal of Economics /over this period. We identify the most active research centres and identify trends in their relative outputs over time. Those research centres successful in publishing in the Top-10 journals are found to also dominate the /Canadian Journal of Economics/. Additionally, we present data on authors' Ph.D.- origin, thereby indicating output and its concentration in graduate education.

Leading by example in a public goods experiment with heterogeneity and incomplete information M. Vittoria Levati Matthias Sutter Eline van der Heijden We study the effects of leadership on the private provision of a public good when group members are heterogeneously endowed. Leadership is implemented as a sequential public goods game where one group member contributes first and all the others follow. Our results show that the presence of a leader increases average contribution levels, but less so than in case of homogeneous endowments. Leadership is almost ineffective, though, if subjects do not know the distribution of endowments. Granting the leaders exclusion power does not lead to significantly higher contributions.

Commitment and Observability in an Economic Environment V. Bhaskar Bagwell (1995) argues that commitment in undermined by the slightest imperfectness in observation. Guth, Ritzberger & Kirchsteiger (1998) question this assertion: for any finite leader-follower game, with arbitrary many players in each role and generic payoffs, they show that there always exists a subgame perfect equilibrium outcome that is accessible, i.e. it can be approximated by the outcome of a mixed equilibrium of the game with imperfect observation. We show that accessibility fails in a class of games played in economic environments, where the payoffs to commitment actions depend upon prices set by other agents, prices being chosen from a continuum. Accessibility requires either that commitment is not required or that the price setting agents have no monopoly power. Our result follows from a generalized indifference principle which mixed strategies must satisfy in such economic environments.

Decentralization and the Productive Efficiency of Government: Evidence from Swiss Cantons Iwan Barankay Ben Lockwood Advocates of fiscal decentralization argue that amongst other benefits, it can increase the productive efficiency of delivery of government services. This paper is one of the first to evaluate this claim empirically by looking at the association between expenditure decentralization and the productive efficiency of government using a data-set of Swiss cantons. We first provide careful evidence that expenditure decentralization is a powerful proxy for factual local autonomy. Further panel regressions of Swiss cantons provide robust evidence that more decentralization is associated with higher educational attainment. We also show that these gains lead to no adverse effects across education types but that male students benefited more from educational decentralization closing, for the Swiss case, the gender education gap. Finally, we present evidence of the importance of competence in government and how it can reinforce the gains from decentralization.

Rodney Ludema (Georgetown University)and Anna Maria Mayda ( Georgetown University and CEPR) (Department of Economics, Georgetown University) The Most-Favored Nation (MFN) clause has long been suspected of creating a free rider problem in multilateral trade negotiations. To address this issue, we model multilateral negotiations as a mechanism design problem with voluntary participation. We show that an optimal mechanism induces only the largest exporters to participate in negotiations over any product, thus providing a rationalization for the Principal supplier rule. We also show that, through this channel, equilibrium tariffs vary according to the Herfindahl index of export shares: higher concentration in a sector reduces free riding and thus causes a lower tariff. Estimation of our model using sector-level tariff data for the U. S. provides strong support for this relationship.

Relative Market Share, Leadership and Competition in Concentrated Banking Markets. Arie Melnik Oz Shy Rune Stenbacka For many years IO economists devoted attention to the size distributions’ of firms in a given industry. Most studies showed that the size distribution of firms in oligopolistic markets is highly skewed. There are many small firms and a few large firms. There is also a consensus that relative market shares are important and that large firms are, in general, more profitable and durable than small firms. Relative size is also important as a determinant of the structure of the industry. The concept is also central in strategic analysis of business firms and in the formulation of government (regulatory) policy. In this paper we propose to use an empirical measure of market leadership. The measure relies on the assumption that the degree of competition critically depends on how dominant the leading firm is in a given industry. The measure also takes into account the number of “significant” competitors in the market and how close they are to the leading firm in terms of size. The measure is simple to use and easy to interpret. It also yields a critical value that facilitates comparisons between different markets.

How Interest Groups with Limited Resources can Influence Political Outcomes: Information Control and the Landless Peasant Movement in Brazil. Lee J. Alston Gary D. Libecap Bernardo Mueller In this paper we examine how an interest group with limited resources (votes and campaign contributions) nevertheless effectively influenced political policy through the control of information to general voters. Voters in turn lobbied politicians to take actions desired by the interest group. Our focus is on the Landless Peasants Movement (Movimento Sem-Terra) or MST and its success in invigorating land reform in Brazil. Although we direct attention to the MST, our analysis can be generalized to interest group behavior in other settings.

Chinatown: Transaction Costs in Water Rights Exchanges. The Owens Valley Transfer to Los Angeles. Gary D. Libecap I re-examine the notorious Owens Valley water transfer to Los Angeles, which is a pivotal episode in the political economy of contemporary western water allocation. Negotiated between 1905 and 1935, it remains one of the largest voluntary water sales in U.S. history. It made the growth of semi-arid Los Angeles possible, increasing the city’s water supply by over 4 times. Water rights were bundled with the land so that the Los Angeles Water Board had to purchase nearly 1,000 small farms. The negotiations between property owners and the agency were complicated. There often were lengthy disputes over farm characteristics, amounts of water conveyed, and valuation of both land and water. Bilateral monopoly emerged between sellers’ pools and the Board. During bargaining impasses, the aqueduct was periodically dynamited. Today, the outcome of the Owens Valley water exchange is viewed as very one sided--one of “theft” by Los Angeles. As such, it discourages contemporary transfers of water from agricultural to urban areas. Using new qualitative and quantitative evidence, especially for 1924-34, when most water- bearing land was purchased, I examine the sources of bargaining conflicts, the timing of sales, the distribution of the gains from trade, and offer a new assessment of the results of the transfer. Implications for current water rights negotiations are drawn. Date: 2005-06 URL: http://d.repec.org/n?u=RePEc:icr:wpicer:16-2005&r=all 67.

Format Choice of Food and Grocery Retailers Sinha Piyush Kumar Mathew Elizabeth Kansal Ankur Format choice is recognized as a cognitive process. Like any other purchasing decision format choice also is an information processing behavior. A store is chosen based on the confidence that the customer has regarding the store; about the nature and quality of product and service he will receive. In Indian scenario formats have been found to be influencing the choice of store as well as orientation of the shoppers (Sinha and Uniyal, 2005). This study seeks to analyze the various factors influencing decision making process of customers in choosing a store format. A full-profile* procedure was used for the Conjoint Analysis in this study. The exploratory study brought out five different formats that existed in the food and grocery sector. With this it also identified combinations of the seven parameters have given rise to some generic retail formats. It also helped identifying the important factor set which affects consumer format choice decisions. The findings also provide details useful for retailers in designing an efficient retail package to offer their customers. * Full-profile conjoint analysis has been a popular approach to measure attribute utilities. In the full- profile conjoint task, different product descriptions (or even different actual products) are developed and presented to the respondent for acceptability or preference evaluations. Each product profile is designed as part of a fractional factorial experimental design that evenly matches the occurrence of each attribute with all other attributes. By controlling the attribute pairings, the researcher can estimate the respondent’s utility for each level of each attribute tested.

Patricia Jensen, Helen H. Evidence from recent U.S. food consumption surveys provides new information on the distribution of rice consumption, the characteristics of rice consumers, and the diets of people who consume rice. Recently available data from nationally representative surveys of food consumed by individuals in the United States allowed comparison of consumption today (2001-02) with consumption in the mid-1990s. Data come from the Continuing Survey of Food Intakes by Individuals (1994-96) and the National Health and Nutrition Examination Survey (2001-02). Rice is consumed by a significant portion of the U.S. adult population. In 2001-02, over 18 percent (18.2 percent) of adults reported eating at least half a serving of white or brown rice in one day of observed intake. This share was slightly higher than that of 1994-96 (17.4 percent). Compared with others, individuals who consumed at least half a serving of white or brown rice in the observed day of intake consumed a smaller share of calories per day from fat and saturated fat; less discretionary fat or added sugar; and more fiber, dietary folate, fruit, vegetables, and enriched grains. Consumers eating rice were more likely to eat a diet that included choices of foods consistent with the 2005 U.S. Dietary Guidelines. Keywords: dietary guidelines, rice consumption.

Heckman (University of Chicago, University College London, American Bar Foundation and IZA Bonn) Lance Lochner (University of Western Ontario) Dimitriy V. Masterov (University of Chicago) This paper presents economic models of child development that capture the essence of recent findings from the empirical literature on skill formation. The goal of this essay is to provide a theoretical framework for interpreting the evidence from a vast empirical literature, for guiding the next generation of empirical studies, and for formulating policy. Central to our analysis is the concept that childhood has more than one stage. We formalize the concepts of self-productivity and complementarity of human capital investments and use them to explain the evidence on skill formation. Together, they explain why skill begets skill through a multiplier process. Skill formation is a life cycle process. It starts in the womb and goes on throughout life. Families play a role in this process that is far more important than the role of schools. There are multiple skills and multiple abilities that are important for adult success. Abilities are both inherited and created, and the traditional debate about nature versus nurture is scientifically obsolete. Human capital investment exhibits both self- productivity and complementarity. Skill attainment at one stage of the life cycle raises skill attainment at later stages of the life cycle (self-productivity). Early investment facilitates the productivity of later investment (complementarity). Early investments are not productive if they are not followed up by later investments (another aspect of complementarity). This complementarity explains why there is no equity-efficiency trade- off for early investment. The returns to investing early in the life cycle are high. Remediation of inadequate early investments is difficult and very costly as a consequence of both self- productivity and complementarity.

Contrary to recent studies, we estimate that immigration induced important net gains and small redistributive effects among natives. Our analysis relies on a computable general equilibrium model combining the major interactions between immigrants and natives ( labor market impact, fiscal impact, capital deepening, endogenous education, endogenous inequality). We use a backsolving method to calibrate the model on historical data and then consider two counterfactual variants: a cutoff of all immigration flows since 1950 and a stronger selection policy. According to our simulations, the postwar US immigration is beneficial for all cohorts and all skill groups. These gains are closely related to a long-run fiscal gain and a small labor market impact of immigrants. Finally, we also demonstrate that all generations would have benefited from a stronger selection of immigrants.

The Determinants of the Prevalence of Single Mothers: A Cross-Country Analysis Libertad Gonzalez (Universitat Pompeu Fabra and IZA Bonn) This paper examines the effect of public assistance, labor market and marriage market conditions on the prevalence of single mother families across countries and over time. A multinomial logit derived from a random utility approach is estimated using individual-level data for 14 countries. I find evidence that increases in the level of public support are significantly and positively associated with a higher incidence of both never married and divorced mothers. The results also suggest that single mothers are more prevalent when female wages are lower. Higher male earnings and employment opportunities in a woman’s marriage market appear to lead to fewer never married mothers, but more divorced mothers. Higher child support or alimony payments are associated with a higher prevalence of divorced mothers.

Optimum Income Taxation and Layoff Taxes Pierre Cahuc (CREST-INSEE, University of Paris 1, CEPR and IZA Bonn) Andre Zylberberg (EUREQua, University of Paris 1 and CNRS) This paper analyzes optimum income taxation in a model with endogenous job destruction that gives rise to unemployment. It is shown that optimal tax schemes comprise both payroll and layoff taxes when the state provides public unemployment insurance and aims at redistributing income. The optimal layoff tax is equal to the social cost of job destruction, which amounts to the discounted value of the sum of unemployment benefits (that the state pays to unemployed workers) and payroll taxes (that the state does not get when workers are unemployed). Our quantitative analysis suggests that the introduction of layoff taxes, that are usually absent from actual tax schemes, could lead to significant increases in employment and GDP.

The Perverse Effects of Partial Employment Protection Reform: Experience Rating and French Older Workers Luc Behaghel (LEA-INRA) Bruno Crepon (CREST-INSEE and IZA Bonn) Beatrice Sedillot (DARES) French firms laying off workers aged 50 and above have to pay a tax to the unemployment insurance system, known as the Delalande tax. This is an original case of experience rating in the European context, restricted to older workers, whose employment prospects are particularly bad. We evaluate its impact on layoff ( firing) as well as on hiring, taking advantage of several changes in the measure since its introduction in 1987. We find particularly strong evidence of an adverse effect of the tax on the firms’ propensity to hire older workers, thanks to a legislative change in 1992, when workers hired after the age of 50 stopped being liable for the tax. Chances to find a job increased significantly for unemployed workers older than 50, compared to workers just below 50 who remained liable for the tax. We estimate that before 1992, the tax reduced the probability that an unemployed worker aged 50 find a job by as much as 25%. Evidence on the effect on layoffs is less clear cut. The impact is sizeable only for the most stringent tax schedule, after 1998, but it is also imprecisely estimated.

The Economics of Workaholism: We Should Not Have Worked on This Paper Daniel S. Hamermesh (University of Texas at Austin, NBER and IZA Bonn) Joel Slemrod (University of Michigan and NBER) A large literature examines the addictive properties of such behaviors as smoking, drinking alcohol and eating. We argue that for some people addictive behavior may apply to a much more central aspect of economic life: working. Workaholism is subject to the same concerns about the individual as other addictions, is more likely to be a problem of higher-income individuals, and can, under conditions of jointness in the workplace or the household, generate negative spillovers onto individuals around the workaholic. Using the Retirement History Survey and the Panel Study of Income Dynamics, we find evidence that is consistent with the idea that high-income, highly educated people suffer from workaholism with regard to retiring, in that they are more likely to postpone earlier plans for retirement. The theory and evidence suggest that optimal policy involves a more progressive tax system than in the absence of workaholism.

Labour Market Institutions and the Personal Distribution of Income in the OECD Daniele Checchi (University of Milan and IZA Bonn) Cecilia Garcia Penalosa (CNRS and GREQAM) We examine what determines differences across countries and over time in the distribution of personal incomes in the OECD. We first model the wage determination process and show that unemployment, the labour share, and the wage differential are all functions of labour market institutions. Next we show that in a model economy with only four types of agents - capitalists, skilled and unskilled workers, and unemployed - the Gini coefficient of personal incomes can be expressed as a function of the above three variables. Labour market institutions hence affect income inequality, though the sign of their impact is ambiguous. Stronger unions and/or a more generous unemployment benefit tend to reduce inequality through reduced wage differentials, a higher labour share, and also higher unemployment. We then use a panel of OECD countries for the period 1970-96 to examine these effects. We find, first, that the labour share remains an important aspect of overall inequality patterns, and, second, that stronger unions and a more generous unemployment benefit tend to reduce income inequality. High capital-labour ratios also emerge as a strong equalising factor, which has in part offset the impact of increasing wage inequality on the US distribution of personal incomes.

Friendship Relations in the School Class and Adult Economic Attainment Andrea Galeotti (California Institute of Technology and University of Essex) Gerrit Mueller (Erasmus University Rotterdam, Tinbergen Institute and IZA Bonn) We analyze the impact of adolescents’ friendship relations in their final-year class of high school on subsequent labor market success. Based on a typology of network positions we locate each student within the social system of the school class as either: an isolate, a sycophant, a broker or a receiver. These positions identify individuals’ social standing within the group of classmates and proxy for their interpersonal behavior and social competencies. We offer empirical evidence that differential social standing in adolescence predicts large and persistent earnings disparities over the entire life course. The estimated wage premia and penalties do not appear to be substantially confounded by measures of family and school resources, and materialize largely independent of differences in cognitive abilities, grade rank in class, personality traits or friends’ characteristics. A moderate share of the earnings inequalities is mediated by differential post-secondary human and social capital investment. From a conceptual point of view, we contribute an application of egocentered network methods within conventional labor economic survey research.

Yann Algan (Universite Marne la Vallee, CEPREMAP, OEP and IZA Bonn) Pierre Cahuc (University of Paris 1, CREST-INSEE, CEPR and IZA Bonn) OECD countries faced largely divergent employment rates during the last decades. But the whole bulk of the cross-national and cross-temporal heterogeneity relies on specific demographic groups: prime-age women and younger and older individuals. This paper argues that family labor supply interactions and cross- country heterogeneity in family culture are key for explaining these stylized facts. First we provide a simple labor supply model in which heterogeneity in family preferences can account for cross-country variations in both the level and the dynamics of employment rates of demographic groups. Second, we provide evidence based on international individual surveys that family attitudes do differ across countries and are largely shaped by national features. We also document that cross-country differences in family culture cause cross-national differences in family attitudes. Studying the correlation between employment rates and family attitudes, we then show that the stronger preferences for family activities in European countries may explain both their lower female employment rate and the fall in the employment rates of young and older people.

The Curse and Blessing of Training the Unemployed in a Changing Economy: The Case of East Germany After Unification Michael Lechner (SIAW, University of St. Gallen, CEPR, ZEW, PSI and IZA Bonn) Ruth Miquel (SIAW, University of St. Gallen) Conny Wunsch (SIAW, University of St. Gallen) We analyse the effects of government-sponsored training for the unemployed conducted during East German transition. For the microeconometric analysis, we use a new, large and informative administrative database that allows us to use matching methods to reduce potential selection bias, to study different types of programmes, and to observe interesting labour market outcomes over 8 years. We find that, generally, all training programmes under investigation increase long-term employment prospects and earnings. However, as an important exception, the longer training programmes are on average not helpful for their male participants. At least part of the explanation for this negative result is that caseworkers severely misjudged the structure of the future demand for skills.

Price Volatility and Banking in Green Certificate Markets Eirik S. Amundsen (Department of Economics, University of Bergen) Fridrik M. Baldursson (Department of Economics, University of Iceland) Jorgen Birk Mortensen (Institute of Economics, University of Copenhagen) There is concern that prices in a market for Green Certificates ( GCs) primarily based on volatile wind power will fluctuate excessively, leading to corresponding volatility of electricity prices. Applying a rational expectations simulation model of competitive storage and speculation of GCs the paper shows that the introduction of banking of GCs may reduce price volatility considerably and lead to increased social surplus. Banking lowers average prices and is therefore not necessarily to the benefit of “green producers”. Proposed price bounds on GC-prices will reduce the importance of banking and even of the GC system itself.

Nouvelles Technologies et Nouvelles Formes d'Organisation du Travail : Quelles consequences pour l'emploi des salaries ages ? Aubert Patrick Caroli Eve Roger Muriel This paper investigates the relationships between new technologies, innovative workplace practices and the age structure of the workforce in a static labour demand framework. As a first step, we assume that, in the short run, the only variable factor is the number of workers in different age groups. We then assume, as a second step that the number of workers by age and skill group may vary. The data we use come from several sources: the Changements Organisationnels et Informatisation survey (COI); the Declarations Annuelles des Donnees Sociales ( DADS) and the Benefices Reels Normaux database (BRN). We find evidence that the wage-bill share of older workers is lower in innovative firms. This age bias affects is also evidenced within occupational groups, thus suggesting that skills do not completely protect workers against the labour-market consequences of ageing..

Merger Policy to Promote Global Players? A Simple Model Haufler, Andreas Nielsen, Soren Bo We use a simple framework where firms in two countries serve their respective domestic markets and a world market to analyze under which conditions cost-reducing mergers will be beneficial for the merging firms, the home country, and the world as a whole. For a national merger, the policies enacted by a national merger authority tend to be overly restrictive from a global efficiency perspective. In contrast, all international mergers that benefit the merging firms will be cleared by either a national or a regional regulator, and this laissez-faire approach is also globally efficient. Finally, we derive the properties of the endogenous merger equilibrium. JEL: H77 F13 L41 Date: 2005-07 URL: http://d.repec.org/n?u=RePEc:lmu:muenec:666&r=all 83. Fairness, Adverse Selection, and Employment Contracts von Siemens, Ferdinand This paper considers a firm whose potential employees have private information on both their productivity and the extent of their fairness concerns. Fairness is modelled as inequity aversion, where fair-minded workers suffer if their colleagues get more income net of production costs. Screening workers with equal productivity but different fairness concerns is shown to be impossible if both types are to be employed, thereby rendering the optimal employment contracts discontinuous in the fraction of fair-minded workers. As a result, fairness might infuence the employment contracts of all workers although only some are fair- minded, and identical firms facing very similar pools of workers might employ very different remuneration schemes.

Bhowmik Maxwell L. King In this paper, we consider the problem of estimation of semi- linear regression models. Using invariance arguments, Bhowmik and King (2001) have derived the probability density functions of the maximal invariant statistic for the nonlinear component of these models. Using these density functions as likelihood functions allows us to estimate these models in a two-step process. First the nonlinear component parameters are estimated by maximising the maximal invariant likelihood function. Then the nonlinear component, with the parameter values replaced by estimates, is treated as a regressor and ordinary least squares is used to estimate the remaining parameters. We report the results of a simulation study conducted to compare the accuracy of this approach with full maximum likelihood estimation. We find maximising the maximal invariant likelihood function typically results in less biased and lower variance estimates than those from full maximum likelihood.

Deriving Tests of the Semi-Linear Regression Model Using the Density Function of a Maximal Invariant Jahar L. Bhowmik Maxwell L. King In the context of a general regression model in which some regression coefficients are of interest and others are purely nuisance parameters, we derive the density function of a maximal invariant statistic with the aim of testing for the inclusion of regressors (either linear or non-linear) in linear or semi-linear models. This allows the construction of the locally best invariant test, which in two important cases is equivalent to the one-sided t-test for a regression coefficient in an artificial linear regression model.

Calvo Alejandro Izquierdo Rudy Loo-Kung Sudden Stops are associated with increased volatility in relative prices. We introduce a model based on information acquisition to rationalize this increased volatility. An empirical analysis of the conditional variance of the wholesale price to consumer price ratio using panel ARCH techniques confirms the relevance of Sudden Stops and potential balance- sheet effects as key determinants of relative-price volatility, where balance-sheet effects are captured by the interaction of a proxy for potential changes in the real exchange rate (linked to the degree of external leverage of the absorption of tradable goods) and a measure of domestic liability dollarization.

Trade Policy Reforms and the Structure of Protection in Vietnam Prema-chandra Athukorala This paper examines the current state of the trade policy regime in Vietnam against the backdrop of market-oriented policy reforms undertaken over the past one-and-a-half decades. The core of the paper is an in-depth analysis of the structure of protection, focussing on both incentives for import-competing production the bias in the incentive structure against export production compared to import-competing production. It is found that, despite notable reform efforts, the structure of protection in Vietnam is still out of line with that of the major trading nations in the region, in terms of the level and the inter- industry dispersion of nominal and effective protection rates. There is a clear ani-export bias in the incentive structure, even though the degree of the bias has considerably declined over the years. There is no evidence to justify the existing protection structure on grounds of infant industry protection or employment generation.

Production Fragmentation and Trade Integration: East Asia in a Global Context Prema-chandra Athukorala Nobuaki Yamashita This paper examines the implications of international production fragmentation for analysing global and regional trade patterns, with special emphasis on countries in East Asia. It is found that, while 'fragmentation trade' has generally grown faster than total world manufacturing trade, the degree of dependence of East Asia on this new form of international specialisation is proportionately larger compared to North America and Europe. International production fragmentation has certainly played a pivotal role in continuing dynamism of the East Asian economies and increasing intra-regional economic interdependence. There is, however, no evidence to suggest that this new form of international exchange has contributed to lessoning the regions dependence on the global economy. On the contrary, growth dynamism based on vertical specialisation depends inexorably on extra-regional trade in final good, and this dependence has in fact increased over the years.

Testing for Asymmetries in the Preferences of the Euro-Area Monetary Policymaker Alvaro Aguiar (CEMPRE, Faculdade de Economia, Universidade do Porto) Manuel M. F. Martins (CEMPRE, Faculdade de Economia, Universidade do Porto) This paper tests for asymmetries in the preferences of the Euro- Area monetary policymaker with 1995:I-2004:III data from the last update of the ECB's Area-wide database. Following the relevant literature, we distinguish between three types of asymmetry: precautionary demand for expansions, precautionary demand for price stability and interest rate smoothing asymmetry. Based on the joint GMM estimation of the Euler equation of optimal policy and the AS-AD structure of the macroeconomy, we find evidence of precautionary demand for price stability in the preferences revealed by the monetary policymaker. This type of asymmetry is consistent with the ECB’s definition of price stability and with the priority of credibility-building by a recently created monetary authority.

Underlying Inflation: Concepts, Measurement and Performance Ivan Roberts (Reserve Bank of Australia) This paper explores the concept of underlying inflation and the properties of various measures of underlying inflation in the Australian context. Underlying inflation measures are routinely calculated and monitored by central banks in many countries, including the Reserve Bank of Australia. Alternative measurement concepts are explored, and a range of measures that have been calculated for Australia are discussed and evaluated on the basis of statistical criteria. These criteria capture the intuition that a good measure of underlying inflation should be less volatile than CPI (or headline) inflation, be unbiased with respect to CPI inflation, and capture the 'trend' in CPI inflation so that, on average, CPI inflation will tend to adjust towards the measure of underlying inflation. In the Australian context, statistical measures of underlying inflation, such as the trimmed mean or weighted median, perform fairly satisfactorily against these criteria. The performance of these measures can be further improved by seasonally adjusting prices at the CPI component level. Although underlying inflation measures have become less necessary in the past decade as inflation itself has become less volatile, these findings suggest that underlying inflation measures can still add value to the analysis of inflationary trends.

A Three-Layer Atmosphere-Ocean Time Series Model of Global Climate Change David I. Stern (Department of Economics, Rensselaer Polytechnic Institute, Troy, NY 12180-3590, USA) Time series models of global climate change have tended to estimate a low climate sensitivity and a fast adjustment rate to equilibrium. These results appear to be biased by omission of a key variable - heat stored in the ocean. I develop a time series model of the ocean atmosphere climate system where atmospheric temperature moves towards a long-run equilibrium with both radiative forcing and ocean heat content, which is distributed between upper ocean and deep ocean components. The time series model utilizes the notion of multicointegration to impose energy balance relations on an autoregressive model. As there are only around fifty years of observations on ocean heat content I use the Kalman filter to estimate heat content as a latent state variable constrained by the available observations. The estimate of the equilibrium climate sensitivity is 8.4K with a confidence interval of 5.0 to 11.7K. Temperature takes centuries to adjust to an increase in radiative forcing. The transient climate sensitivity at the point of carbon dioxide doubling is 1.7K. JEL: Q53 Q54 Date: 2005-07 URL: http://d.repec.org/n?u=RePEc:rpi:rpiwpe:0510&r=all 93. No euro please, We’re British! Lucio Valerio Spagnolo, Mario Cerrato (CELPE-DISES, Universita degli Studi di Salerno) Comparing the economic performances between UK and Euroland, the appropriate and obvious question should be: why does not Euroland replace its euro with the British pound? However, economy does not represent all the interests of the human beings. They believe in values beyond the economy. Right! It may well be that Euroland citizens, once with the euro, feel much more confiance in themselves, as part of a larger world, as they trust the monetary and political decision makers of the EU Institutions. If that was the truth, the European integration process should proceed just like a ball thrown against standing skittle-pins waiting to be got down! Unfortunately, that is not the case. The authors try to point out some reasons to understand those British people who love to look at the euro experience, sitting in their armchairs and, above all, without loosing their national pound.

Trew This paper surveys the literature on the relationship between finance and growth from a longitudinal, and primarily theoretical, perspective. Important qualifications to the empirical consensus are noted and we consider the prevalence of cross-section econometrics as dominant in shaping the present theoretical consensus. We develop a general model capable of capturing a number of key conclusions from theoretical research. We then trace out the numerical implications of this class of models for time-series growth, as well as outlining ways in which these models might be tested quantitatively for historical congruence. We suggest a reason for the preponderance of theoretical considerations of financial efficiency despite empirical analysis of financial deepness, and how this makes direct comparisons between the theory and empirics of finance and growth difficult. The core implications of many finance and growth theories are shown to be incongruent with the historical record. Keywords: finance and growth, endogenous growth, economic history.

It takes three to tango: Soft budget constraint and cream skimming in the hospital care market Levaggi, Rosella Montefiori, Marcello Cream skimming is an illegal behaviour that consists in choosing to treat patients according to their ability to recover. It arises from the use of prospective payment schemes in an asymmetry of information framework. In this context in fact the provider can observe some relevant information (freely or at a cost) before making its effort which will then be used to its own advantage. The paper studies the scope for these types of behaviour in a mixed market for hospital care where the hospitals do not share the same objectives. We show that in this context cream skimming is made possible by the presence of two important elements: the public hospital prefers to treat high severity patients and the regulator is unable to enforce hard budget constraint rules. The paper adds an important dimension to the study of cream skimming as proposed by the traditional literature where asymmetry of information alone is considered the cause of this market failure. In our context, in fact, cream skimming arises mainly from a regulatory failure. JEL: I11 I18 D82 Date: 2005-07 URL: http://d.repec.org/n?u=RePEc:uca:ucapdv:48&r=all 96. Elimination of the Foreign Property Rule on Tax Deferred Savings Plans Joel Fried (University of Western Ontario) The Foreign Property Rule (FPR), limiting the holding of foreign property in pension plan assets, is scheduled to be eliminated this year. It has been rationalized on economic grounds by asserting that it improves the value of the dollar and decreases the cost of capital yet, at the time the FPR began, the government was trying to keep the dollar from rising and there were strong capital inflows. Further, evidence from the past changes in the FPR indicates it had little, if any, affect on the cost of capital and exchange rate, but cost middle income workers between one and three billion dollars per annum when set at 30%. I argue that the reason for its existence was the then common belief that governments could make better economic allocation decisions than markets. Removing the FPR provides pension plans with greater opportunity for risk adjusted returns as well as responsibilities. Relevant issues that arise include the degree of foreign currency exposure that is desirable and the degree of active management desired in foreign assets, and whether it makes sense to choose fund managers that are regionally focused rather than global. Pension boards will also have to rethink what a Canadian fund is and whether it should mimic Canadian production ( as currently structured) or Canadian consumption patterns. An encouraging aspect of eliminating the FPR is the possibility that government ideology is changing to place greater emphasis on the positive benefits of using markets to allocate resources.

THE GROWING THREAT OF GLOBAL POVERTY: The Case of Africa Ingo Bobel (International University of Monaco) The goal is to try to give inputs on a global problem: eradicating poverty on a global scale. That is, to find evidence and discuss complex problems regarding cronic poverty, a major source of instability in our world today, and to put forward what could be some possible solutions. The aim of this endeavour is to further sensitize public opinion to a major, chronic and exponential problem that is affecting an increasing number of the population world wide. The focus is on (sub-Saharan) Africa and its (past and present) problems. Sub-Saharan Africa is the region which has the greatest percentage of its population in poverty and also the greatest depth of poverty. Questions that will be explored and addressed are, among others, related to agriculture, water management, education, health, the role of woman in society, and especially micro credits and micro lending – all questions related to how the threat of global poverty can be averted, and how the world can be shaped for the benefit of future generations.

Zak (Claremont Graduate University) The traditional view in economics is that individuals respond to incentives, but absent strong incentives to the contrary selfishness prevails. Moreover, this “greed is good” approach is deemed “rational” behavior. Nevertheless, in daily interactions and in numerous laboratory studies, a high degree of cooperative behavior prevails—even among strangers. A possible explanation for the substantial amount of “irrational” behavior observed in markets (and elsewhere) is that humans are a highly social species and to an extent value what other humans think of them. This behavior can be termed trustworthiness—cooperating when someone places trust in us. I also analyze the cross-country evidence for environments that produce high or low trust. A number of recent experiments from my lab have demonstrated that the neuroactive hormone oxytocin facilitates trust between strangers, and appears to induce trustworthiness. In rodents, oxytocin has been associated with maternal bonding, pro-social behaviors, and in some species long- term pair bonds, but prior to the work reviewed here, the behavioral effects of oxytocin in humans had not been studied. This presentation discusses the neurobiology of positive social behaviors and how these are facilitated by oxytocin. My experiments show that positive social signals cause oxytocin to be released by the brain, producing an unconscious attachment to a stranger. I also discuss recent research that manipulates oxytocin levels, and functional brain imaging research on trust.

Accessing Formal Credit: Social Capital versus ‘Social Position’ (Lesson from a Javanese Village) Aloysius Gunadi Brata (Research Institute, University of Atma Jaya Yogyakarta) Low access to formal credit persists in most of developing economies also in Indonesia. Most of households especially in rural areas do not familiar with formal credit. Therefore, formal credit institution needs a mediation or substitution. Recent studies argue that social capital could to a better flow of information between creditors and borrowers and hence less adverse selection and moral hazard in the market for credit. The guarantee of groups and pressure by social network also are important techniques to improve credit performance. The relation between social capital and credit access is an interesting issue since the promotion of formal credit facilities in rural areas is argued as an important policy in reducing poverty level. The aim of this paper is to describe the connection between social capital and access to formal credit, especially from commercial banking in the case of a Javanese village. To describe the connection, this paper will seek what are the different characteristics between household that having access to commercial credit and the other group of households. However, since there is also an argument that social capital does not guarantee poor people to access formal credit, this paper also analyse other important variable namely ‘social position’ of the head of household in their rural community.

Banks, Markets, and Efficiency Falko Fecht (Deutsche Bundesbank) Antoine Martin (Federal Reserve Bank of New York) Following Diamond (1997) and Fecht (2004) we use a model in which financial market access of households restrains the efficiency of the liquidity insurance that banks' deposit contracts provide to households that are subject to idiosyncratic liquidity shocks. But in contrast to these approaches we assume spacial monopolistic competition among banks. Since monopoly rents are assumed to bring about inefficiencies, improved financial market access that limits monopoly rents also entails a positive effect. But this beneficial effect is only relevant if competition among banks does not sufficiently restrain monopoly rents already. Thus our results suggest that in the bank- dominated financial system of Germany, in which banks intensely compete for households' deposits, improved financial market access might reduce welfare because it only reduces risk sharing. In contrast, in the banking system of the U.S., with less competition for households' deposits, a high level of households' financial market participation might be beneficial.

Building a Better Fund of Hedge Funds: A Fractal and Alpha - Stable Distribution Approach Yan Olszewski (Maple Financial Alternative Investments) Markowitz’s (1952) portfolio theory has permeated financial institutions over the past 50 years. Assuming that returns are normally distributed, Markowitz suggests that portfolio optimization should be performed in a mean-variance framework. With the emergence of hedge funds and their non-normally distributed returns, mean-variance portfolio optimization is no longer adequate. Here, hedge fund returns are modeled with the alpha-stable distribution and a mean-CVaR portfolio optimization is performed. Results indicate that by using the alpha- stable distribution, a more efficient fund of hedge funds portfolio can be created than would be by assuming a normal distribution. To further increase efficiency, the Hurst exponent is considered as a filtering tool and it is found that combining hedge fund strategies with particular Hurst exponents leads to the creation of more efficient portfolios as characterized by higher risk- adjusted ratios. These findings open the door for the further study of econophysics tools in the analysis of hedge fund returns.

The intraday price of money: evidence from the e-MID market Angelo Baglioni (Universita Cattolica del Sacro Cuore) Andrea Monticini (University of Exeter) We present a simple model, where intraday and overnight interest rates are linked by a no-arbitrage argument. The hourly interest rate is shown to be a function of the intraday term structure of the overnight rate. This property holds under both assumptions, where an explicit intraday market for interbank loans exists and when it does not. In the first case, such a property is an equilibrium condition; in the second one it holds by definition, as a synthetic hourly loan is a portfolio of overnight contracts. We then provide empirical evidence, based on tick- by-tick data for the e-MID money market (covering the whole 2003). The overnight rate shows a clear downward pattern throughout the operating day. A positive hourly interest rate emerges from the intraday term structure of the overnight rate: we estimate the market price of a one hour interbank loan to be slightly above a half basis point.

Sustainability of the Slovenian Pension System: An Analysis with an Overlapping-generations General Equilibrium Model Miroslav Verbic (Institute for Economic Research Ljubljana) Boris Majcen (Institute for Economic Research Ljubljana) Renger van Nieuwkoop (ECOPLAN Berne) The article presents an analysis of welfare effects in Slovenia, an analysis of macroeconomic effects of the Slovenian pension reform and an analysis of effects of the pension fund deficit on sustainability of Slovenian public finances with a dynamic OLG general equilibrium model. It has been established that while young generations and new generations will lose from the pension reform, even complete implementation of the reform might not be sufficient to compensate unfavourable demographic developments. The level of expected deficit of the PAYG-financed state pension fund seems to be most worrying. Financing the pension system with VAT revenues as an extreme case could result in more sustainable public finances, since GDP and welfare levels ought to increase, yet this might be infeasible to implement politically, given that the generations of voters would have their welfare decreased. In addition, the present pension system is intransparent and tremendously complicated and should primarily be made more comprehensible to the public.

Growth, private investment and reforms : A comparative perspective Ghazouani KAMEL (Hight trade school of Tunis, Manouba University) In this paper we empirically analyse the linkages among growth, investment and reforms in the South East Asian countries, in the North Africa and in the non CFA Sub-Saharan Africa economies over 1970-89 to 2003. These regions differ considerably among them selves as well as with regard to the rest of the world, in terms of resources endowment, structure of production , and also in terms of economic reforms , physical infrastructure, and human capital. Our empirical analysis has clearly revealed the importance and the complementarities between macroeconomic reforms, physical infrastructure, human capital and structural reforms for the growth prospects of the economies. These factors have shown a strong effect on growth and have contributed greatly to the growth process for north Africa countries and the non CFA sub Sahara African countries. In north Africa economies and in the Sub Sahara African countries, the lack of macroeconomic reforms, the deficiencies of the physical infrastructure and the human capital explain, although at differing degrees , well the deficit in economic growth. This has been particularly the case of road networks, electronic equipments, sanitary conditions and schooling. The model simulation shows that an improvement of secondary schooling and physical infrastructure, similar to South East Asia, would have stimulated North Africa economic growth by respectively 0.61percent and 0.17 percent against only 1.23 percent and 0.39 percent for non CFA Sub Saharan Africa Keywords: Growth , reforms, Human capital , Structural reforms, macroeconomic stability, PCA, investment, Panel JEL: C23 C82 E17 O40 Date: 2005-07-22 URL: http://d.repec.org/n?u=RePEc:wpa:wuwpge:0507012&r=all 107. Virtual Branding: Turning a stone into a Jewel David Ward (European School of Economics) Dario Secondi (Amway Italia) This short paper discusses the evolution of branding and its projection in the near and distant future. In particular it examines and suggests why certain brands have become legends and common place e.g. Coca Cola, Mercedes, McDonalds etc. The authors start from Sapir-Whorf’s hypothesis for linguistic determinism to show that he who controls the vocabulary of branding could, in effect, control the world of products and services simply because we are hindered if not incapable of evaluating other options. The paper places emphasis on two aspects of the future of branding: 1. the ultimate limit of branding, that the authors have baptised as V-Branding (Virtual Branding), and 2. the development of a framework, process and assessment tool that allows companies to evaluate and steer their brand(s). The assessment tool, denominated as the RIB matrix-graph (Real-Imaginary Branding matrix- graph) can be used in 2D format (with Awareness and Degree of Diffusion forming the two axes or dimensions) and 3D format i.e. with an additional dimension such as age group, social status, period, time frame etc. Tool applicability stretches from the small business to transnational companies and from products to services. The paper also looks at the transition from lifestyles to mindstyles, the evolution of the consumer and how these link to branding evolution.

Gender Inequality in a Globalizing World Stephanie Seguino (University of Vermont & The Levy Economics Institute) Emphasis on market-friendly macroeconomic and development strategies in recent years has resulted in deleterious effects on growth and well- being, and has done little to promote greater gender equality. This paper argues that the example of East Asia states, which recognized their position as “late industrializers,” relied on a managed-market approach with the state that employed a wide variety of policy instruments to promote industrialization. Nevertheless, while Asian growth was rapid, it was not enough to produce greater gender equality. A concentration of women in mobile export industries that face severe competition from other low-wage countries reduces their bargaining power and inhibits closure of gender-wage gaps. Gender- equitable macroeconomic and development policies are thus required, including financial market regulation, regulation of trade and investment flows, and gender- sensitive public sector spending..

From Planning to Mature: on the Determinants of Open Source Take Off Fabio M. Manenti (Universita di Padova Italy) Stefano Comino (Universita di Trento Italy) Marialaura Parisi (Universita di Brescia Italy) In this paper we use data from SourceForge.net, the largest open source projects repository, to estimate the main determinants of the progress in the development of a stable and mature code of a software. We find that the less restrictive the licensing terms the larger the likelihood of reaching an advanced development status and that this effect is even stronger for newer projects. We also find that projects geared towards system administrators appear to be the more successful ones. The determinants of projects' development stage change with the age of the project in many dimensions, i.e. licensing terms, software audience and contents, thus supporting the common perception of open source as a very dynamic phenomenon. The data seem to suggest that open source is evolving towards more commercial applications.

The Erosion of Tariff Preferences: The Impact of U.S. Tariff Reductions on Developing Countries Kara Reynolds (American University) The Generalized System of Preferences (GSP), the program instituted in 1976 that allows developing countries to export thousands of products to the United States duty-free, is an important element of U.S. efforts to promote economic growth in the developing world. However, since the program's inception U.S. tariff rates have fallen significantly, thus potentially reducing the ability of the GSP program to encourage U.S. imports from beneficiary countries. This paper estimates the impact of U.S. tariff reductions on imports from the developing world using a panel of import data from 76 countries and 2,389 GSP-eligible products between 1998 and 2001. It finds that reductions in U.S. tariff rates have diminished imports from developing countries significantly, although some countries have been impacted more than others.

International Mobility of Highly-Qualified People in APEC Surendra Gera (Industry Canada) Thitima Songsakul (Industry Canada) An important aspect of the global knowledge-based economy is the emergence of a new trend where certain groups of highly-qualified workers have become increasingly mobile internationally. Reaching the goal of being more innovative economy requires that the highly-qualified workforce is of sufficient quantity and quality to support the expansion of innovative activities by firms. Many industrialized countries compete strategically in attracting these workers. It is necessary that the economic policy discussion surrounding the international mobility of skilled labour must take into consideration the wide variety of ways the migration of labour affects the economy. Numerous drivers, policy and non-policy induced, are at work. Attention must now turn towards the links between these movements and the regulating institutions; the performance in the trade of goods and services, FDI, human capital formation and multinational enterprises location, and income convergence among countries. This paper focuses on four key issues: First, it examines the global trends in the international migratory flows of highly qualified persons ( HQPs), focusing on APEC economies. Second, it discusses the fundamental non-policy drivers of the increased HQP flows in the new global economy. Third, it reviews the literature on the economic costs and benefits associated with cross-country movement of HQPs and the main factors conditioning these costs and benefits. Finally, it addresses the question of how policy in APEC economies has adjusted or should adjust to the increased international HQP mobility.

International Mobility of Skilled Labour: Analytical and Empirical Issues, and Research Priorities Surendra Gera (Industry Canada) Samuel Laryea (Human Resources Development Canada) Thitima Songsakul (Industry Canada) The international mobility of skilled labour has become a key component of the global knowledge-based economy. Rising levels of foreign direct investment (FDI), international trade, research and development (R&D), technological advances and increased demand for skilled workers seem to have all contributed to an increase in the international mobility of skilled labour. Internationally mobile individuals are often found participating in industries that are largely knowledge-based and global in scope. As a result, it has become increasingly important that the economic policy discussion surrounding the international mobility of skilled labour must take into consideration the wide variety of ways the migration of skilled labour affects the economy. Numerous drivers, policy and non-policy induced, are at work. Attention must now turn towards the links between these movements and the institutions regulating them; the performance in the trade of goods and services; FDI; human capital formation and multinational enterprises location; and income convergence among countries. This paper provides an overview of the literature on four key issues surrounding the international mobility of skilled workers, while identifying potential directions for future research. First, global trends of recent international skilled migratory flows – magnitude and their composition in terms of underlying skills/education of migrants with a focus on Canada-US migratory flows. Second, fundamental (non-policy) drivers of the increased skilled migratory flows, especially among advanced countries. Third, economic costs and benefits associated with cross-country movement of skilled labour and the main factors conditioning these costs and benefits. Fourth, how policy has adjusted or should adjust to increased skilled labour mobility in the global economy?

EXCHANGE RATE AND INFLATION TARGETING IN MOROCCO AND TUNISIA Grand Nathalie (Institut de la Mediterranee, Marseille, FRANCE) Dropsy Vincent (California State University, Fullerton, USA) Morocco and Tunisia have started to open their markets to international trade and capital flows in order to bolster investment and growth. These liberalization programs require important adjustments in their economic policies, in particular their exchange rate regimes and monetary policies. This objective of this paper is to examine why Morocco and Tunisia should progressively opt for greater exchange rate flexibility as well as a monetary policy based on inflation targeting rather than exchange rate targeting and money-growth rules, as their markets are increasingly liberalized. First, their past economic policies are reviewed and analyzed. Second, the theoretical sources of inflation (cost push and demand pull factors as well as factors due to financial liberalization) are identified. Third, a Markov switching model with time-varying transition probabilities is estimated for Morocco and Tunisia to provide important information concerning the mechanisms underlying inflation regime changes. The empirical results provide evidence that high inflation regimes are more persistent in Morocco than in Tunisia, and that inflation regime switches can be explained by external shocks in the 1970s, and by the sound fiscal and monetary policies in the mid-1980s. Finally the institutional and operational conditions for the success of an inflation-targeting framework are outlined.

Non-linear real exchange rate effects in the UK labour market Gabriella Legrenzi (Keele University) Costas Milas (Keele University) Using UK data over the 1973q1-2004q1 period, we find that the dynamics of the real exchange rate, real wages and unemployment vary both with large versus small real exchange rate disequilibria and rising versus falling unemployment regimes. The short-run real exchange rate adjusts only when large disequilibrium deviations occur. We report fast real exchange rate adjustment in periods of falling unemployment. This implies that prices and wages are more flexible when real output is high. When the real exchange rate is highly undervalued, workers respond to an improvement in domestic competitiveness by demanding and getting higher wages. Unemployment is reduced following gains in competitiveness when the real exchange rate is further away from equilibrium.

Tolerance For Uncertainty and the Growth of Informationally Opaque Industries Rocco Huang (University of Amsterdam) Hofstede (1980)’s cross-country psychological survey of IBM employees shows that some countries (societies) are systematically more tolerant of uncertainty, while tolerance of uncertainty is shown by Rigotti et al. (2003)’s model to be essential to the growth of “emerging sectors about which little is known”. We use Durnev, Morck and Yeung (2004)’s methodology to identify these informationally opaque industries. We hypothesize that, countries characterized by high uncertainty aversion (measured by Hofstede’s indicator) will, because of uncertainty aversion, grow disproportionately slower in industrial sectors where information is less available (proxied by lower informativeness of stock prices in the U.S., Durnev et al. 2004). Using the Rajan and Zingales (1998) “differences-in- differences” methodology, in 34 countries and 36 manufacturing industries, we indeed find robust evidence for this pattern of industrial growth. We also show that national uncertainty aversion is not proxying for under-development of financial sector, inadaptability of civil law systems, lower level of economic development, or many other factors. Our results are also robust when we use religious (Protestant/Catholic) composition to instrument for national uncertainty aversion.

The Price Puzzle and Indeterminacy Efrem Castelnuovo (University of Padua) Paolo Surico (Bank of England & University of Bari) This paper re-examines the empirical evidence on the price puzzle and proposes a new theoretical interpretation. Using structural VARs and two different identification strategies based on zero restrictions and sign restrictions, we find that the positive response of price to a monetary policy shock is historically limited to the sub-samples associated with a weak central bank response to inflation. These sub-samples correspond to the pre-Volcker period for the US and the pre-inflation targeting regime for the UK. Using a micro-founded DSGE sticky price model of the US economy, we then show that the structural VARs are capable of reproducing the price puzzle on artificial data only when monetary policy is passive and hence multiple equilibria arise. In contrast, the DSGE model never generates on impact a positive inflation response to a policy shock. The omission in the VARs of a variable capturing the high persistence of expected inflation under indeterminacy is found to account for the price puzzle observed on actual data.

Andrea Monticini (University of Exeter) Giacomo Vaciago (Universita Cattolica del Sacro Cuore) This paper investigates the degree and nature of economic and monetary policy relations among the United States, the Euro area, and Great Britain. Using daily interest rates, we estimate the impact of monetary policy announcements of a Central Bank on its domestic market and in what measure those announcements are able to influence other financial markets. In particular, we analyse the effect of the FED, ECB, and BoE monetary policy announcements on European markets. We find that Europe’s interest rates have a relevant response to FED announcements.

L’ATTRACTION DES IDE EST UNE QUESTION D’ADAPTATION INSTITUTIONNELLE : Modele theorique et estimations pour les regions PECO & MENA Ghazouani kamel (Ecole superieure de commerce de Tunis) Cet article analyse les elements determinants des flux nets d’IDE. Son cadre theorique repose sur le concept de l'adaptation institutionnelle a l'IDE, celle-ci affirme que l'IDE est moins determine par des elements fondamentaux que par des variables institutionnelles qui se pretent plus au changement, a savoir les politiques, les lois et leur application. La theorie de l'adaptation institutionnelle suggere que chaque pays a la possibilite d'identifier et de developper ses facteurs de competitivite pour augmenter sa part dans l'investissement direct etranger global. Le concept d'adaptation a l'IDE est teste dans une etude econometrique sur donnees de PANEL a travers 37 economies representant les pays des zones PECO et MENA. Il s’ensuit de cette analyse econometrique que les variables liees a l’environnement politique sont les elements determinants les plus significatifs des influx d'IDE. L'adaptation politique se reflete dans l'ouverture economique avec un minimum de controle sur le commerce et le taux de change. L'adaptation politique signifie aussi un etat de droit sain et un bas niveau de corruption, reposant sur l'egalite et la transparence juridique et administrative. L'adaptation du marche est representee par des volumes eleves d'echanges commerciaux, un bas niveau de taxation, un degre eleve d'urbanisation et la presence du credit. Comme ces facteurs determinants decouragent le comportement arbitraire et la recherche du benefice personnel, les resultats des regressions econometriques prouvent que, bien qu'ils acceptent de negocier, les investisseurs cherchent la stabilite et la transparence et preferent des reglements nets et appliques de facon reguliere a des privileges individuels obtenus par des marchandages. La facon dont les politiciens dirigent les institutions, les politiques, les lois et leur application est beaucoup plus importante aux yeux des investisseurs directs etrangers que des facteurs relativement immuables tels que l'importance de la population et le milieu socioculturel.

Does Inefficiency Justify Privatization? The Case of Intermediate Industry Monopolies Gerhard Glomm (Indiana University) Fabio Mendez (University of Arkansas) We use an infinitely lived agent model in which an intermediate good is provided either by a public or a private monopolist to study the effects of privatization on steady state levels of income. We allow for public sector inefficiencies(x-inefficiency) which shift down the intermediate goods technology as well as bureaucratic inefficiencies which decrease the amount of tax revenue which will actually be allocated to public investment. We solve the model numerically for reasonable parameter values. The results of the model indicate that the benefits of this type of privatizations depend crucially on the size of the relative inefficiency of public firms and the amount of public investment. Furthermore, the gains from privatization are found to be strongly related to the balance sheet of the public firm that is privatized. Privatization of public firms which run deficits ( surpluses) typically generate increases (decreases) in steady state consumption.

The size and performance of public sector activities in Europe Heinz Handler (Austrian Institute of Economic Research) Bertrand Koebel (University of Strasbourg) Philipp Reiss (University of Madgeburg) Margit Schratzenstaller (Austrian Institute of Economic Research) The obvious difference in the economic performance of countries has led to the question why some countries are so much wealthier than others, and whether the size, the structure, and the organisation of the public sector contribute to cross-country income and growth gaps. Public sector activities may have an effect on overall productivity and growth either directly by the level and changes of productivity within the public sector, or indirectly by triggering off productivity changes in private production. This paper is concerned with the former aspect. It provides an overview of the size and the structure of the public sector in Europe and compares it with the US and Japan. This is related to the more recent empirical literature on public sector performance. After reviewing some of the measurement issues related to public services, the evidence on the size of government and its performance is analysed. The results on industrial countries are not fully conclusive, but seem to attribute more efficiency to smaller rather than to larger governments. Public sector reforms to consolidate the size of government are therefore likely to enhance the sector's own productivity and thereby positively contribute to overall economic performance.

Das oeffentliche Auftragswesen im gesamtwirtschaftlichen Zusammenhang Heinz Handler (Austrian Institute of Economic Research) This paper, written in German language, deals with public procurement policies in the European Union in an overall economic context. Public sector contracts for goods and services make up about one sixth of Community GDP. Governments of all levels tend to rely on local firms when extenting delivery contracts. This may be in conflict with the rules of the EU internal market which, for larger contracts, request competition among bidders. The current essay discusses the possible tensions between competition in the market and the regulation of public procurement. Public contracts have been used to implement additional policy goals, such as social and environmental aspects or to aid small business. The latter goal is often blurred by the tendency to centralise procurement in order to increase the market power of public demand. In general, such a mix of goals may reduce the efficiency of procurement policy.

Fast Computation of the Economic Capital, the Value at Risk and the Greeks of a Loan Portfolio in the Gaussian Factor Model Pavel Okunev (Lawrence Berkeley National Laboratory) We propose a fast algorithm for computing the economic capital, Value at Risk and Greeks in the Gaussian factor model. The algorithm proposed here is much faster than brute force Monte Carlo simulations or Fourier transform based methods. While the algorithm of Hull-White is comparably fast, it assumes that all the loans in the portfolio have equal notionals and recovery rates. This is a very restrictive assumption which is unrealistic for many portfolios encountered in practice. Our algorithm makes no assumptions about the homogeneity of the portfolio. Additionally, it is easier to implement than the algorithm of Hull- White.

Helena Beltran (Universite catholique de Louvain, CORE) Alain Durre (Catholic University of Lille, Institut d'Economie Scientifique et de Gestion) (National Bank of Belgium, Research Department) Pierre Giot (University of Namur) (CORE, Universite catholique de Louvain) This paper looks at the interplay of volatility and liquidity on the Euronext trading platform during the December 2, 2002 to April 30, 2003 time period. Using transaction and order book data for some large- and mid-cap Brussels-traded stocks on Euronext, we study the ex-ante liquidity vs volatility and ex-post liquidity vs volatility relationships to ascertain if the high volatility led to decreases in liquidity and large trading costs. We show that the provision of liquidity remains adequate when volatility increases, although we do find that it is more costly to trade and that the market dynamics is somewhat affected when volatility is high.

Measuring inflation persistence: a structural time series approach Maarten Dossche (National Bank of Belgium, Research Department) Gerdie Everaert (Ghent University, Study Hive for Economic Research and Public Policy Analysis (SHERPPA)) Time series estimates of inflation persistence incur an upward bias if shifts in the inflation target of the central bank remain unaccounted for. Using a structural time series approach we measure different sorts of inflation persistence allowing for an unobserved timevarying inflation target. Unobserved components are identified using Kalman filtering and smoothing techniques. Posterior densities of the model parameters and the unobserved components are obtained in a Bayesian framework based on importance sampling. We find that inflation persistence, expressed by the halflife of a shock, can range from 1 quarter in case of a costpush shock to several years for a shock to longrun inflation expectations or the output gap.

Optimal Commodity Taxation When Land and Structures Must Be Taxed at the Same Rate Saku Aura (Department of Economics, University of Missouri- Columbia) Thomas Davidoff We show that the optimal property tax rate rises with the ratio of land rents to structure and land development costs. California’s high ratio of income to property tax revenue and the distribution of Federal housing subsidies thus appear geographically misplaced. Proportional taxation of non-housing commodities is not optimal, even when elasticities with respect to wages are identical. Absent externalities, the desirability of transportation taxes and“anti-sprawl” growth controls hinge on the relative importance of time versus money in commuting costs.

Putting a Smiley Face on the Dragon: Wal-Mart as Catalyst to U.S.-China Trade Emek Basker (Department of Economics, University of Missouri- Columbia) Pham Hoang Van (Department of Economics, University of Missouri-Columbia) Retail chains and imports from developing countries have grown sharply over the past 25 years. Wal-Mart’s chain, which currently accounts for 10% of U.S. imports from China, grew 10- fold and its sales 90-fold over this period, while U.S. imports from China increased 30-fold. We relate these trends using a model in which scale economies in retail interact with scale economies in the import process. Combined, these scale economies amplify the effects of technological change and trade liberalization. Falling trade barriers increase imports not only through direct reduction of input costs but also through an expanded chain and higher investment in technology. This mechanism can explain why a surge in U.S. imports followed relatively modest tariff declines and why Wal-Mart abandoned its “Buy American” campaign in the 1990s. Also consistent with these facts, we show that tariff reductions have a greater effect the more advanced the retailer’s technology. The model has implications for the pace of the product cycle and sheds light on the recent apparent acceleration in foreign outsourcing.

A theory of low inflation in a non Ricardian economy with credit Constraints. Xavier Ragot This paper explores the relationship between the severity of credit constraints and long run inflation in a simple non Ricardian setting. It is shown that a low positive inflation can loosen credit constraints and that this effect yields a theory of the optimal long run inflation target with no assumption concerning nominal rigidities or expectation errors. Credit constraints introduce an un-priced negative effect of the real interest rate on investment. Because of this effect, the standard characterization of economic efficiency with the Golden Rule fails to apply. When fiscal policy is optimally designed, the first best allocation can be achieved thanks to a positive inflation rate and a proportional tax on consumption.

Facundo Albornoz Gregory Corcos Regional integration affects location decisions of MNCs and therefore influences each member country's provision of investment incentives, which in turn may trigger relocation. As a consequence, subsidy competition increases as integration proceeds. We analyze the welfare consequences of this phenomenon, modelling subsidization as a game between a MNC facing different location alternatives and governments that may deter or induce relocation by means of subsidies. We show that the combination of integration and subsidy competition may lead to an excess of subsidization. We also discuss how the interest of harmonizing subsidies, the net gains from integration crucially depend on technological differences, ownership and the absorption capacity of MNC profits by countries. Lastly, we find that the gain from supranational subsidy coordination increases with integration. Date: 2005 URL: http://d.repec.org/n?u=RePEc:pse:psecon:2005-21&r=all 130. The Reform of Local Taxation in the United Kingdom in the Light of The Balance of Funding Review Report. Fender, John. Currently, local authorities in the UK raise only about a quarter of their revenues from taxes under their control. The Balance of Funding Review Report considered whether this proportion should be increased, and if so, how. This paper considers the report and possible reforms. Reasons why the balance of funding is a problem are discussed. However, there are problems with the current system apart from the balance of funding, and to solve some of these a closer link between council tax bills and property values is suggested. Whether a local income tax should be introduced as a supplement to a reformed council tax, and other possible reforms, are also discussed.

Non-Linear Strategies in a Linear Quadratic Differential Game Rowat, Colin We study non-linear Markov perfect equilibria in a two agent linear quadratic differential game. In contrast to the literature owing to Tsutsui and Mino (1990), we do not associate endogenous subsets of the state space with candidate solutions. Instead, we address the problem of unbounded-below value functions over infinite horizons by use of the 'catching up optimality' criterion. We present sufficiency conditions for existence based on results in Dockner, Jorgenson, Long, and Sorger (2000). Applying these to our model yields the familiar linear solution as well as a condition under which a continuum of non-linear solutions exist. As this condition is relaxed when agents are more patient, and allows more efficient steady states, it resembles a Folk Theorem for differential games. The model presented here is one of atmospheric pollution; the results apply to differential games more generally.

Robert In this paper we build upon the robust procedures proposed in Vogelsang (1998) for testing hypotheses concerning the deterministric trend function of a univariate time series. Vogelsang proposes statistics formed from taking the product of a normalised) Wald statistic for the trend function hypothesis under test with a specific function of a separate variable addition Wald statistic. The function of the second statistic is explicitly chosen such that the resultant product statistic has pivotal limiting null distributions, coincident at a chosen level, under I(0) or I(1) errors. The variable addition statistic in question has also been suggested as a unit root statistic, and we propose corresponding tests based on other well-known unit root statistics. We find that, in the case of the linear trend model, a test formed using the familiar augmented Dickey-Fuller [ADF] statistic provides a useful complement to Vogelsang's original tests, demonstrating generally superior power when the errors display strong serial correlation with this pattern tending to reverse as the degree of serial correlation in the errors lessens. Importantly for practical considerations, the ADF-based tests also display significantly less finite sample over-size in the presence of weakly dependent errors than the original tests.

A Note Ganguly, Chirantan; Ray, Indrajit In the Crawford-Sobel (uniform, quadratic utility) cheap-talk model we allow for mediation in which the informed agent reports one possible element of a partition to a mediator (a communication device) and then the mediator suggests an action to the uninformed decision-maker according to the probability distribution of the device. We compare the unmediated N-partition equilibrium of the Crawford-Sobel model with a mediated equilibrium involving exactly N elements to report and N actions to choose from. We show that such a mediated equilibrium cannot improve upon the unmediated N-partition equilibrium when the preference divergence parameter is small.

Ambiguity in Financial Markets: Herding and Contrarian Behaviour Ford, James L; Kelsey, D; Pang, W The paper studies the impact of ambiguity on history-dependant beahviour in the standard microstructure model of financial markets. We show that differences in ambiguity attitudes between market makers and traders can generate contrarian and herding behaviour in stock markets where assets are traded sequentially and trading prices are endogenously determined. We also show the mispricing can be only short-term, and in the long-run market is efficient in the sense that the market price aggregates information without distortions.

Arms Trade Offsets and Development Jurgen Brauer (Augusta State University) J Paul Dunne (School of Economics, University of the West of England) Offsets, arrangements that obligate the arms seller to reinvest ( “offset”) arms sales proceeds in the purchasing country, are an increasingly important facet of the international trade in arms. They are used to justify spending on imports by promises that there will be significant benefits to the economy, through the promotion and development of local industry, technology and employment. Until recently, however, there has been little research on how well offsets work in practice. This paper is a ‘state-of-the-art’ review of our empirical knowledge regarding arms trade offsets. We find virtually no case where offset arrangements have yielded unambiguous net benefits for a country’s economic development. As a general rule arms trade offset deals are more costly than ‘off-the-shelf’ arms purchases, create little by way of new or sustainable employment, do not appear to contribute in any substantive way to general economic development, and with very few exceptions do not result in significant technology transfers, not even within the military sector.

Choice of Monetary and Exchange Regimes in ECOWAS: An Optimum Currency Area Analysis Chantal Dupasquier (UN Economic Commission for Africa) Patrick N. Osakwe (UN Economic Commission for Africa) Shandre M. Thangavelu (Department of Economics, National University of Singapore) There are plans by five West African countries to establish a second monetary zone in the sub-region by December 2009. In this paper we ask whether a monetary union is the appropriate exchange rate regime for the sub-region based on economic criteria. We address the issue using a rigorous theoretical framework that captures the crucial trade-off between the savings in transaction costs, resulting from a common currency, and the macroeconomic stabilization benefits of a flexible exchange rate regime. The main result is that a flexible exchange rate regime dominates a monetary union in the ECOWAS subregion.

We show both theoretically and numerically that climate policy responds differently to variations in the two parameters. In particular, we show that higher gamma but lower rho leads to increase emissions control. We also argue that climate-economy models based on intertemporal expected utility maximization, i.e. models where gamma = rho, may misinterpret the sensitivity of the climate policy to risk-aversion.

Elle releve davantage d'une rationalite politique et administrative qu'economique et gestionnaire. Nous soutenons que la mise en oeuvre de nouvelles formes de contrats publics (tels les contrats de partenariat public-prive) a cadre comptable inchange risque de conduire a une impasse.

The Effects of Beliefs versus Risk Preferences on Bargaining Outcomes David L. Dickinson In bargaining environments with uncertain impasse outcomes (e.g., litigation or labor strike outcomes), there is an identification problem that confounds data interpretation. In such environments, the minimally acceptable settlement value from a risk-averse ( risk-loving) but unbiased bargainer is empirically indistinguishable from what one could get with risk-neutrality and pessimism (optimism). This paper reports data from a controlled bargaining experiment where risk preferences and beliefs are both measured in order to assess their relative importance in bargaining outcomes. The average lab subject is risk-averse, yet optimistic, which is consistent with existing studies that examine each in isolation. I also find that the effects of optimism dominate those of risk-aversion. Optimistic bargainers are significantly more likely to dispute and have aggressive final bargaining positions. Dispute rates are not statistically affected by risk preferences, but there is some evidence that risk aversion leads to less aggressive bargaining positions and lower payoff outcomes. A key implication is that increased settlement rates are more likely achieved by minimizing impasse uncertainty (to limit the potential for optimism) rather than maximizing uncertainty (to weaken the reservation point of risk-averse bargainers), as has been argued in the dispute resolution literature.

Deflation and Downward Nominal Wage Rigidity: Evidence from Japan Kengo Yasui (Graduate School of Economics, Osaka University) Shinji Takenaka (Graduate School of Economics, Osaka University) This study empirically analyzed downward nominal wage rigidity using time-series cross-industry data from 1981 to 2002, a period which included deflation. We found that nominal wages remained rigid to downward pressure by expected deflation and labor-market tightness. Estimations according to worker age categories revealed downward wage rigidity with deflationary pressure for most age categories. Wage rigidity during labor-market tightness was greater for younger workers.

Policy-Induced Mean Reversion in the Real Interest Rate? Zisimos Koustas (Department of Economics, Brock University) Jean-Francois Lamarche (Department of Economics, Brock University) This paper utilizes tests for a unit root that have power against nonlinear alternatives to provide empirical evidence on the time series properties of the ex-post real interest rate in the G7 countries. We find that the unit-root hypothesis can be rejected in the presence of a nonlinear alternative motivated by theoretical literature on optimal monetary policy rules. This represents a reversal of the results obtained using standard linear unit-root and cointegration tests. Tests for linearity reject this hypothesis for Canada, France, Germany, Italy, and the US. For these countries we estimate nonlinear models to capture the dynamics of the ex-post real interest rate.

Banks without Parachutes – Competitive Effects of Government Bail-out Policies Hendrik Hakenes (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Isabel Schnabel (Max Planck Institute for Research on Collective Goods, Bonn, Germany) The explicit or implicit protection of banks through government bail-out policies is a universal phenomenon. We analyze the competitive effects of such policies in two models with different degrees of transparency in the banking sector. Our main result is that the bail-out policy unambiguously leads to higher risk- taking at those banks that do not enjoy a bail-out guarantee. The reason is that the prospect of a bail-out induces the protected bank to expand, thereby intensifying competition in the deposit market and depressing other banks’ margins. In contrast, the effects on the protected bank’s risk-taking and on welfare depend on the transparency of the banking sector.

Optimal Income Taxation, Public-Goods Provision and Public- Sector Pricing: A Contribution to the Foundations of Public Economics Martin Hellwig (Max Planck Institute for Research on Collective Goods, Bonn, Germany) The paper develops an integrated model of optimal nonlinear income taxation, public-goods provision and pricing in a large economy. With asymmetric information about labour productivities and publicgoods preferences, the multidimensional mechanism design problem becomes tractable by requiring renegotiation proofness of the final allocation of private goods and admission tickets for excludable public goods. Under an affiliation assumption on the underlying distribution, optimal income taxation, public-goods provision and admission fees have the same qualitative properties as in unidimensional models. These properties are obtained for utilitarian welfare maximization and for a Ramsey-Boiteux formulation with interim participation constraints.

Cost and Benefits from Infrastructure Competition. Estimating Welfare Effects from Broadband Access Competition Felix Hoffler (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Competition between parallel infrastructures incorporates opposing welfare effects. The gain from reduced deadweight loss might be outweighed by the inefficient duplication of an existing infrastructure. Using data from broadband internet access for Western Europe 2000-2004, this paper investigates which effect prevails empirically. Infrastructure competition between DSL and cable TV had a significant and positive impact on the broadband penetration. Comparing the additional social surplus attributable to cable competition with the cable investments, we conclude that infrastructure competition has not been welfare enhancing. A theoretical model is provided, formalizing why the effect of competition on penetration might be limited.

Switching Costs in Retroactive Rebates – What’s time got to do with it? Frank P. Maier-Rigaud (Max Planck Institute for Research on Collective Goods, Bonn, Germany) This paper analyzes the role of the reference period in assessing switching costs in retroactive rebates. A retroactive rebate allows a firm to use the inelastic portion of demand as leverage to decrease price in the elastic portion of demand, thereby artificially increasing switching costs of buyers. I identify two factors that determine the extent to which retroactive rebates, as a form of infra-personal price- discrimination, can result in potential market foreclosure. These two factors are the rebate percentage and the threshold at which this percentage is retroactively applied. In contrast to the existing literature, the length of the reference period within which a rebate scheme applies is demonstrated to be at best an indirect approximation of the potential foreclosure effects of a rebate.

The Role of Liquidity and Implicit Guarantees in the German Twin Crisis of 1931 Isabel Schnabel (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Using monthly balance-sheet data of all major German credit banks, we analyze deposit with-drawals and bank failures in the German banking and currency crisis of 1931. We find that de-posit withdrawals were driven by the run on the currency, but were also related to banks’ liquidity positions; that branch banks were no more stable than unit banks; and that large banks were privileged, being bailed out and receiving preferential access to the discount window. These findings underline the importance of liquidity and implicit guarantees in twin crises, while they question the benefits of branching in such crises.

Bank Size and Risk-Taking under Basel II Hendrik Hakenes (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Isabel Schnabel (Max Planck Institute for Research on Collective Goods, Bonn, Germany) This paper discusses the relationship between bank size and risk- taking under Pillar I of the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we find that small banks (and hence small borrowers) may profit from the introduction of an internal ratings based (IRB) approach if this approach is applied uniformly across banks. However, the banks’ right to choose between the standardized and the IRB approaches unambiguously hurts small banks, and pushes them towards higher risk-taking due to fiercer competition. This may even lead to higher aggregate risk in the economy.

Monopoly Prices versus Ramsey-Boiteux Prices: Are they "similar", and: Does it matter? Felix Hoffler (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Ramsey-Boiteux prices and monopoly prices are frequently regarded as being similar. This might suggest that, in particular in network industries with large fixed costs, sometimes monopoly pricing is close to the Ramsey-Boiteux second best and welfare superior to imperfectly regulated prices. This paper tries to specify what is meant by "being similar", and it analyzes the welfare implications that can be drawn from comparing both sets of prices. Interdependence of demand and the impact of competition are discussed. We reinforce the view that monopoly prices are usually not "similar", and even if they are, this implies no positive welfare judgments on monopoly pricing.

Altruism and charitable giving in a fully replicated economy Thomas Gaube (Max Planck Institute for Research on Collective Goods, Bonn, Germany) In this paper, an economy is analyzed where one group of agents, the altruists, cares about the well-being of another group of agents, the recipients. It is asked how changes in the size of these groups affect the altruists’ charitable giving in the Nash equilibrium. I show that a pure group size effect, i.e., a proportional expansion of both subgroups can lead to less free riding and to a lower degree of underprovision relative to the efficient level of charitable giving.

Market Definition As a Social Construction (Marktabgrenzung als soziale Konstruktion) Christoph Engel (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Anti-trust cases more often than not hinge upon market definition. The anti-trust authorities use standardised tests for the purpose, like the "small but significant and nontransitory increase in price" test prevalent in US law. These tests are often read as neoclassical economics, watered down to legal scale. They then are interpreted by economic concepts like cross price elasticities. These interpretations rest on methodological individualism. Social phenomena, like competition, are explained from the perspective of actors maximising their individual utility. If one wants to understand how an individual firm is controlled by competition, this is a most helpful approach. But for defining the effective area of competition, or the relevant market, methodological holism is more powerful. Its basic conceptual unit is not the individual, but communication. Markets are seen as implicitly or explicitly organised entities, giving an industry an identity, and helping the consumers orient themselves in a complex environment. Specifically, a market turns out to be a hybrid between co-operation (for constituting the area of competition) and conflict (within the area thus defined). This alternative approach is important for anti-trust practice. The decisive fact is not whether two products "objectively ought to be" substitutes. What market participants see as substitutes is the only thing that matters. Consequently, for market definition, anti-trust authorities may not (only) rely on their own wisdom. They must find ways to reconstruct the communication among market participants.

Learning, Institutions, and Economic Performance Chrysostomos Mantzavinos (Faculty of Economics and Business, Witten/Herdecke University) Douglas C. North (Washington University, St. Louis) Syed Shariq (Institute for International Studies, Stanford University) In this article, we provide a broad overview of the interplay among cognition, belief systems, and institutions, and how they affect economic performance. We argue that a deeper understanding of institutions’ emergence, their working properties, and their effect on economic and political outcomes should begin from an analysis of cognitive processes. We explore the nature of individual and collective learning, stressing that the issue is not whether agents are perfectly or boundedly rational, but rather how human beings actually reason and choose, individually and in collective settings. We then tie the processes of learning to institutional analysis, providing arguments in favor of what can be characterized as “cognitive institutionalism.” Besides, we show that a full treatment of the phenomenon of path dependence should start at the cognitive level, proceed at the institutional level, and culminate at the economic level.

The Democratic Legitimacy of Business Interest Representation in the European Union: Normative Implications of the Logic of Access Pieter Bouwen (Universite Catholique de Louvain, Belgium) This paper studies the capacity of business interests to contribute to the democratic legitimacy of EU governance through participation in the EU policy-making process. Whereas the unbalanced participation of business as opposed to non-business interests in EU policy-making has been problematized, no research has been conducted regarding the unequal participation of different organizational forms of business interest representation (companies, associations and consultants). Here, first it is argued on the basis of a theory of access that this unequal participation has important repercussions because the different organizational forms do not have the same potential to contribute to the legitimacy of EU governance. The theoretical approach makes it possible to bridge the gap between the EU legitimacy debate and the literature on EU business interest representation by establishing a relationship between the new concept of ‘access goods’ and the existing notions of input/output legitimacy. Second, an empirical investigation of business interest participation is undertaken in order to systematically assess the empirical relevance of the normative propositions and consequently to make inferences about the democratic legitimacy of business interest participation in the EU policy-making process.

The ratio of aspiration levels Martin Beckenkamp (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Simon’s (1955) famous paper was one of the first to cast doubt on the validity of rational choice theory; it has been supplemented by many more papers in the last three and a half decades. Nevertheless, rational choice theory plays a crucial role in classical and neoclassical economic theory, which presumes a completely rational agent. The central points characterizing such an agent are: (1) The agent uses all the information that is given to him. (2) The agent has clear preferences with respect to the results of different actions. (3) The agent has adequate competences to optimize his decisions. As an alternative to this conception, Simon (1955) himself suggests the concept of “bounded rationality”. In this context, Simon ( 1956) discusses a principle, which he names the “satisficing principle” (for explanations with respect to this notion cf. Gigerenzer & Todd 1999, p. 13). It assumes that, instead of searching for an optimal action, the search for an action terminates if an alternative has been found that satisfies a given “aspiration level”. It will be demonstrated that although the satisficing principle is nothing but a heuristic, there is a mathematical optimization at work when aspiration levels are used in this kind of problems. The question about the optimal aspiration level can be posed. Optimization within the framework of bounded rationality is possible. However, the way in which such an optimization can be achieved is very simple: Optimal thresholds in binary sequential decisions rest with the median.

The Institutional-Evolutionary Antitrust Model Chrysostomos Mantzavinos (Faculty of Economics and Business, Witten/Herdecke University) The purpose of this article is to provide an alternative antitrust model to the mainstream model that is used in competition policy. I call it the Institutional-Evolutionary Antitrust Model. In order to construct an antitrust model one needs both empirical knowledge and considerations of how to adequately deal with norms. The analysis of competition as an evolutionary process that unfolds within legal rules provides the empirical foundation for the model. The development of the normative dimension involves the elaboration of a comparative approach. Building on those foundations the main features of the Institutional-Evolutionary Model are sketched out and it is shown that its use leads to systematically different outcomes and conclusions than the dominant antitrust ideals.

Public Goods versus Common-Pool Resources Frank P. Maier-Rigaud (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Jose Apesteguia Despite a large theoretical and empirical literature on public goods and common-pool resources, a systematic comparison of these two types of social dilemmas is lacking. In fact, there is considerable confusion about these two types of dilemma situations. As a result, they are often treated alike. In this paper we argue that the degree of rivalry is the fundamental difference between the two games. We show that rivalry implies that both games cannot be represented by the same game theoretic structure. Fur-thermore, we experimentally study behavior in a quadratic public good and a quadratic common-pool resource game with identical Pareto opti-mum but divergent interior Nash equilibria. The results show that partici-pants clearly perceive the differences in rivalry. Aggregate behavior in both games starts relatively close to Pareto efficiency and converges to the respective Nash equilibrium. URL: http://d.repec.org/n?u=RePEc:mpg:wpaper:2004_2&r=all 166. Globalisation and National Incentives for Protecting Environmental Goods Alkuin Kolliker (Max Planck Institute for Research on Collective Goods, Bonn, Germany) This article tries to explain national incentives for protecting environmental goods either autonomously or collectively; it explores how globalisation has affected those incentives; and it suggests how national environmental policy might respond so as to ensure its effectiveness. The central argument is that national incentives for environmental protection may to a considerable extent be explained by a combination of the type of environmental good to be protected (in terms of public goods theory) and the effects of environmental protection measures on international competitiveness. Arrangements for protecting environmental goods can be ranked according to their centripetal effects on non- participating countries. Centripetal effects are strongest in the case of club goods (1), followed by private goods (2), public goods (3), and common pool resources (4). The centripetal effects resulting from the type of environmental good can be further reinforced by competitive advantages resulting from environmental protection measures; they can be weakened by competitive disadvantages; or they can remain unchanged due to competitive neutrality. The combination of four types of environmental goods and three types of competitive effects (positive, negative, neutral) results in twelve possible cases, with differing national incentives for autonomous and collective environmental protection. Given specific assumptions, these twelve cases can be ranked with regard to the severity of collective action problems they involve. The article includes a short empirical illustration for each case. It also analyses how globalisation (in the form of increasing trade) and some of its driving forces (in the form of free trade agreements) influence national incentives and legal possibilities for environmental protection. This article concludes with a brief discussion of four options for (re-) expanding the action space for national environmental policies under the condition of economic globalisation.

Social Dilemmas, Revisited from a Heuristics Perspective Christoph Engel (Max Planck Institute for Research on Collective Goods, Bonn, Germany) The standard tool for analysing social dilemmas is game theory. They are reconstructed as prisoner dilemma games. This is helpful for understanding the incentive structure. Yet this analysis is based on the classic homo oeconomicus assumptions. In many real world dilemma situations, these assumptions are misleading. A case in point is the contribution of households to climate change. Decisions about using cars instead of public transport, or about extensive air conditioning, are typically not based on ad hoc calculation. Rather, individuals rely on situational heuristics for the purpose. This paper does two things: it offers a model of heuristics, in the interest of making behaviour that is guided by heuristics comparable to behaviour based on rational reasoning. Based on this model, the paper determines the implications for the definition of social dilemmas. In some contexts, the social dilemma vanishes. In other contexts, it must be understood, and hence solved, in substantially different ways.

Risk Aversion in the Small and in the Large. When Outcomes are Multidimensional Martin Hellwig (Max Planck Institute for Research on Collective Goods, Bonn, Germany) The paper discusses criteria for comparing risk aversion of decision makers when outcomes are multidimensional. A weak concept, ”commodity specific greater risk aversion”, is based on the comparison of risk premia paid in a specified commodity. A stronger concept, ”uniformly greater risk aversion” is based on the comparison of risk premia regardless of what commodities are used for payment. Neither concept presumes that von Neumann- Morgenstern utility functions are ordinally equivalent. Nonincreasing consumption specific risk aversion is shown to be sufficient to make randomization undesirable in an agency problem with hidden characteristics.

Nonlinear Incentive Provision in Walrasian Markets: A Cournot Convergence Approach Martin Hellwig (Max Planck Institute for Research on Collective Goods, Bonn, Germany) The paper studies insurance with moral hazard in a system of contingent-claims markets. Insurance buyers are modelled as Cournot monopolists or oligopolists. The other agents condition their expectations on market prices, as in models of rational- expectations equilibrium with asymmetric information. Thereby they correctly anticipate accident probabilities corresponding to effort incentives induced by insurance buyers’ net trades. When there are many agents to share the insurance buyer’s risk, Cournot equilibrium outcomes are close to being second-best. In contrast, if insurance buyers are price takers, equilibria fail to exist or are bounded away from being second-best.

Offentlichkeitsarbeit der Regierung (Governmental Public Relations) Christoph Engel (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Should government be allowed to spend tax payers’ money on public relations? If one frames the question that way, the negative answer suggests itself. Yet government communication serves more purposes. These purposes may be analysed in terms of behavioural economics and psychology. In moral suasion, government communication is the governance tool itself. Most other governance tools do not automatically reach their addressees. Appropriate communication is necessary for them to become effective. Finally, government is a legitimate player in political process, and communication to the public is a legitimate element of this process. Specifically, the normatively desirable and the normative problematic aspects can usually not be fully disentangled. Hence, the potential distortion of elections must be outweighed against the governance effect. This paper does so by interpreting governmental public relations as a bundled product. It models the people as the principal, and the political parties running government as the agent. The distortion effect is observable, the governance effect is not. This set-up of the model invites a second-best solution in terms of mechanism design. Government is free to advertise. But advertising is costly in that it generates a handicap at the next elections. This solution is taken as a benchmark for discussing politically more digestible third and forth best alternatives.

The Role of Choice in Social Dilemma Experiments Frank P. Maier-Rigaud (Max Planck Institute for Research on Collective Goods, Bonn, Germany) Jose Apesteguia On the basis of problems related to asymmetric information, self- governance has been proposed and often empirically found to be superior to the external imposition of rules in social dilemma situations. The present paper suggests and experimentally analyses a different line of argument, namely to what extent behavioral aspects can explain these findings. We study this hypothesis using the simplest, most general dilemma form: the prisoner’s dilemma (PD). We compare behavior when players are given the possibility of choosing between two different representations of the same PD, to behavior when players are externally assigned to play a specific game. We find that cooperation rates are significantly higher in the games that were chosen.

University Funding Systems and their Impact on Research and Teaching: A General Framework John Beath (University of St Andrews) Joanna Poyago-Theotoky (University of Loughborough) David Ulph (Inland Revenue) This paper addresses the following question: how does a higher education funding system influence the trade-off that universities make between research and teaching? We do so by constructing a general model that allows universities to choose actively the quality of their teaching and research when faced with different funding systems. In particular, we derive the feasible sets that face universities under such systems and show how, as the parameters of the system are varied, the nature of the university system itself changes. The “culture” of the university system thus becomes endogenous. This makes the model useful for the analysis of reforms in funding and also for international comparisons.

Estonian Inflation Model Urmas Sepp Andres Vesilind Ulo Kaasik The objective of model-building was an inflation model suitable for prognosis as well as for simulation. The model serves two purposes. First of all, it is a tool for analysing inflation. Secondly, it is part of the model of Estonian economy, which completes the adjustment loop of the macromodel. The theoretical background of the inflation model derives from four basic features of Estonian economy. Namely, Estonia is: a small and open economy, a transitional economy, economy under currency board arrangement and a market economy. When estimating the model, inflation was decomposed into a) underlying inflation which is a long-run process and b) inflation deviations from the equilibrium which are caused by the short-run impact of inflation factors. The underlying inflation, which reflects the convergence, is determined as a trend. The latter was specified as a time function, ARMA process, moving average and HP filter, whereas the best result was obtained with time function. According to modelling output the short run dynamics of the inflation are determined by three main factors - demand pressure reflected by the GDP gap, exchange rate of the US dollar (which is proxy for foreign prices), and administrative action for correcting regulated prices. The adequacy of the model has been tested on the basis of ex post and ex ante prognosis. The model provided acceptable results in the simulation of endogenous and exogenous shocks URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2000-01&r=all 176. Assessment of the Euro\'s implications for European economic development Iika Korhonen Mare Randveer This paper assesses the impacts of Economic and Monetary Union and the euro on developments within the EU and globally. The emphasis is on euro-11 countries and the eight most advanced accession candidates in Central and Eastern Europe. The single currency completes the project for a single market in Europe, and overall, clear efficiency gains for participating countries are expected. Low, stable interest rates should spur investment and the single currency should promote the formation of large, liquid capital markets, eventually transforming the structure of financial intermediation within the euro area. Although participating countries achieved a high degree of nominal convergence in the 1990s, this process now appears to have ended. Moreover, the conduct of a common monetary policy becomes more problematic with countries at different phases in the economic cycle. Accession candidates may use a variety of foreign exchange rate regimes before they join the EU, but ultimately their economic policies become a matter of common interest. Pressure to peg to the euro obviously increases as membership approaches, but there is compelling evidence that countries should hold back on pegging to the euro until they have achieved sufficient convergence to attain credibility for a policy of fixed exchange rates.

Equilibrium exchange rate of the Estonian kroon, its dynamics and impacts of deviations Fabio Filipozzi The aim of the analysis presented here is to examine the behaviour of the real exchange rate of the Estonian kroon, to estimate its equilibrium value and investigate its impact on the competitiveness of Estonian economy. A brief account on possible measures of the real exchange rate (RER) is given, and then the real effective exchange rate (REER) weighted with domestic and foreign consumer price indices (CPI) is chosen for the estimation. A model for the equilibrium real exchange rate (ERER) determination suitable for a small open economy as Estonia is outlined and provides a theoretical basis for understanding what kind of fundamentals can affect real exchange rate behaviour. Given the short sample considered here, a single equation estimation method is used. The choice of fundamentals is determined both by particular features of the Estonian economy and data constraint. The fundamentals finally adopted are productivity differential between tradeables and nontradeables sectors, investment share, resource balance and nominal effective exchange rate. Having detected the existence of one cointegration vector between RER and fundamentals, it is possible to estimate the long-run relationship linking them and an error correction mechanism in order to have some information on short-run behaviour of the real exchange rate. Estimation results are then used to construct both ERER series and misalignment measures. To do this, some hypotheses on equilibrium/sustainable levels of fundamentals are set and discussed. Our simulation hence brings us to conclude that an appreciation of RER in the sample period occurred together with an appreciation of its equilibrium level. The latter appreciated slower, hence the initial undervaluation was corrected and the difference between RER and its equilibrium level shrank, leading to a slight overvaluation after the Russian crisis.

The monetary sector under a currency board arrangement : specification and estimation of a model with Estonian data Rasmus Pikkani Modelling work on Estonian data indicates that external financing of the private sector has strong impact on domestic demand, which implies that valuable insights may be gained in this case from understanding the behavioural relationships in the monetary sector. The current paper provides a theoretical analysis of the monetary sector under a currency board regime and applies specification tests to Estonian data. As a final product, empirical equations for average lending rate, loans provided to the private sector and money demand are estimated. While estimations herein use monthly data, quarterly modifications of the model will be inserted into Eesti Pank\'s quarterly macromodel in the future.

Determinants of Estonian export of goods: an econometric analysis and comparison with Latvia and Lithuania Andres Vesilind Laura Ehrlich The goal of this paper was to analyse empirically the importance of different determinants of Estonian export and compare the results with Latvia and Lithuania. For a theoretical model, the imperfect substitutes model was chosen. For empirical estimation Estonian nominal export was disaggregated by commodity groups, by customs procedures and by groups of destination countries. Besides that an equation of real aggregate goods\' export and models of Latvian and Lithuanian export by commodity groups were estimated. According to estimated models Estonian export is mainly determined by manufacturing output in Finland and Sweden and real economic growth in other EU countries. Also real consumption in neighbouring countries is important for Estonian export, but here the countries of influence change - the influence of Russia declines as the influence of Western countries rises. Prices and exchange rates have smaller effect to Estonian exports. The comparison of the results of Estonian export modelling to those of Latvia and Lithuania shows that the main determinants of export in three countries are different. While Estonian export is mainly influenced by Nordic economies, Latvian and Lithuanian export is mainly influenced by Germany and the UK. The influence of Russia has declined in all three countries, remaining the highest in the case of Lithuania. URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2001-01&r=all 180. Potential output estimates for Central and East European countries using production function method Marit Hinnosaar In the paper potential output of four Central and East European countries is estimated using the Cobb-Douglas production function. Estonian production function uses data of employment, sectoral restructuring, estimated capital stock and foreign direct investments. Capital stock and level of technology are estimated for the Central and East European countries using the same form of production function and parameter estimates of Estonian economy. Potential output is calculated using the long-term unemployment to approximate potential labour input in the production. According to the estimates potential output is higher than actual in all the countries during most of the period, except in the fast economic growth periods (in the Czech Republic in 1995-1996, Estonia in 1997-1998 and Latvia in 1997, respectively).

Determinants of Estonian Sovereign Credit Rating Andres Vesilind Ingrid Toming Raoul Lattemae The paper focuses on sovereign credit ratings assigned to Estonia and analyses their possible determinants. The first chapter gives an overview of different rating agencies and the methodology they use in rating process. Besides that the interpretation, comparability and explanatory power of different ratings are analysed. The chapter concludes with the description of Estonian rating history. The second chapter analyses the possible determinants of Estonian rating. Firstly, the possible problems in analysing the determinants are discussed. Secondly, the factors that have been seen as important determinants of ratings in theoretical literature or previous empirical researches are presented. The third chapter analyses empirically the determinants of Estonian credit rating. For this purpose, Estonia is analysed in the context of three country groups: former socialist countries, developed European countries and countries having similar ratings. Also the factors that different rating agencies have pointed out in their reports about Estonia are compared with the empirical results. The chapter concludes with the comparison of the results of the analysis and SWOT analysis. The results of the paper show that the most critical factors for Estonia that can constrain possible rating upgrade in the future are low nominal level of per capita GDP, high unemployment rate and high CA deficit. At the same time it should be looked after that other important indicators that have a strong relation with rating (such as inflation, fiscal balance, foreign debt level and speed of transition and EU accession) are kept under control.

Monetary transmission mechanism in Estonia - some theorethical considerations and stylized aspects Raoul Lattemae The monetary system in Estonia is based on the currency board arrangement. The strong commitments and rule-based features of currency board imply that there is no active monetary policy in Estonia - all necessarily monetary adjustments are left to the market forces. Under fixed exchange rate and free capital mobility Estonian monetary conditions are therefore closely linked with monetary policy in Europe - in addition to the changes in Estonian risk-premium, interest rate developments in Europe can directly influence Estonian interest rates. Those monetary signals transmit widely into Estonian financial sector and ultimately into Estonian real sector through various channels. Some theoretical and intuitive aspects that can affect this process in Estonia have gained special attention in this paper. URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2001-04&r=all 183. Monetary transmission mechanism in Estonia - empirical model Rasmus Pikkani Estonia has conducted effectively monetary policy according to currency board arrangement for nine years already. For this Estonia has traded off its freedom in active monetary policy operations for nominal anchoring economy through exchange rate. In this context Estonian own monetary policy actions could hardly make any difference and Estonian monetary conditions are heavily relying on decisions made by the issuer of anchor currency. At the same time, there are number of factors having influence on the degree of dependence on foreign monetary factors, most important of which is the openness of the economy to all balance of payments flows and the strength of the domestic banking sector. A mix of all possible factors and decision-making rules in the economy specifies directly the speed and the strength of transmission of foreign monetary signal into domestic economy. The aim of the current paper is to study transmission of ECB monetary policy decisions into Estonian economy. Additionally, absorption of unanticipated foreign and domestic monetary shocks are analysed. For this, rather small macroeconometric model with 11 behavioural equations is specified and estimated. Special emphasis is given on the formation of domestic interest rates and on the intermediation of domestic and foreign funds by domestic banking sector over shock periods. As a result, it is found that the transmission of ECB monetary policy actions over European inter-bank money market into Estonian economy is relatively fast. This is probably mostly due to high openness of the economy and to high price and wage flexibility in Estonia. URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2001-05&r=all 184. Accession to EMU and exchange rate policies in Central Europe - decision under institutional constraints Andreas Freytag Currently, five Central and Eastern European (CEE) countries are negotiating about the membership in the European Union: Czech Republic, Estonia, Hungary, Poland and Slovak Republic. There is a broad consensus that they will eventually become members of the European Monetary Union. This requires careful analysis of the appropriate exchange rate regime prior to the accession. The exchange rate arrangement of the EU applicants plays an important but not exclusive - role in their policy-mix. The history of transition economies as well as of other emerging markets illustrates that exchange rate policies as such are not a distinctive factor for the success and failure of monetary policy with respect to price stability. In this paper it is argued that this outcome has not emerged by chance. There is no naturally superior exchange rate regime that can be applied to all advanced countries in transition aiming at stability. By way of contrast, an exchange rate arrangement is part of the monetary regime, which itself is a component of the economic order. The latter consists of both politically chosen and spontaneously evolved institutions. This leads to the hypothesis that the choice of an exchange rate arrangement in CEE is constrained by this institutional setting. The theoretical considerations as well as empirical evidence indeed suggest that for guaranteeing stability, beside the legal monetary commitment (part of which being the exchange rate regime) the institutional framework in the country is decisive. If the latter matches the commitment, the credibility of a monetary regime is relatively high, obviously encouraging monetary stability. Therefore, the institutional setting in each country should be analysed extensively before an exchange rate arrangement is chosen. URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2002-01&r=all 185. Integrated monetary and exchange rate frameworks: are there empirical differences? Lucio Vinhas de Souza The aim of the paper is to empirically estimate whether the different monetary and exchange rate frameworks observed in the accession countries of Central and Eastern Europe and the Baltic States do yield different outcomes in terms of level and variance of a set of nominal and real variables. The author follows and extends the methodology developed by Kuttner and Posen (2001), who perform a combined analysis of the individual effects of exchange rate regimes, central bank independence and announced targets in nominal variables for a large set of developed and developing countries. They also estimate that a set-up combining a free float, an independent currency board and inflation targeting yields an outcome that mimics the price stabilisation advantages of a hard peg without its drawbacks in terms of extreme volatility. This sample of countries, not covered by the Kuttner and Posen study, supports their conclusions for both nominal and real variables, testing for both the individual and combined effects of the frameworks and indicating that a flexible exchange rate regime, coupled with CBI and DIT, would be Pareto- improving when compared to harder regimes.

The impact of Scandinavian economies on Estonia via foreign trade and direct investments Laura Ehrlich Ulo Kaasik Anu Randveer The paper focuses on the benefits, challenges and risks of the Estonian economy stemming from close relations with its main foreign partners Finland and Sweden, through foreign direct investments and foreign trade. The paper gives a short overview of Finnish and Swedish economies to provide a background for the analysis of the characteristics of FDI and trade flows between Estonia and these countries. As Estonia is a very small and open economy main benefits and challenges are related to it. The authors find that FDI from Finland and Sweden increase the credibility of Estonian economy, but as foreign investment flows are subject to push factors they have the potential of destabilising capital flows, because these two countries make over 70% of FDI into Estonia. The authors also find that the dynamics of Estonian exports to Finland and Sweden (which make more than half of total exports) is generally determined by the demand factors of those countries.

Aspects of the Sustainability of Estonian Currency Board Arrangement Urmas Sepp Martti Randveer The main aim of the paper is to examine different aspects of the sustainability of Estonian CBA. For this purpose the paper gives an overview of CBA in general, describes the rationale for the choice of the CBA in Estonia and uses model simulations to assess its sustainability. It also analyses whether the preconditions for the successful performance of the CBA are in place in Estonia and discusses the compatibility of Estonian CBA to the EMU and ERM 2. The analysis in the paper shows that CBA is a suitable exchange rate regime for Estonia. It is argued that the preconditions for a well-functioning CBA - resilient financial sector, flexible wage and employment system and prudent fiscal policy - are in place. The sustainability of the CBA is also supported by model simulations, which show that shocks hitting Estonian economy do not cause convergence of the Estonian economy from the long-run path. Based on the above-mentioned results, the paper concludes that the currency board arrangement is the best exchange rate regime for Estonia before the full participation in the third stage of the EMU.

The Core of a Macro-economic Model for Estonia Olivier Basdevant Ulo Kaasik This article presents a macro-econometric model for Estonia currently developed at the Bank of Estonia. It is based on a basic macro-economic framework that integrates both supply and demand side components.

The main emphasis is on the need to continue tough fiscal policy in order to maintain public deficit, as well as to avoid inflationary pressures and keep Estonia attractive to foreign investors.

Unemployment and Labour Mobility in Estonia: Analysis Using Duration Models Marit Hinnosaar The current paper analyses unemployment and labour movements between labour market statuses in the period of January 1997 to July 2000 using data from the Estonian Labour Force Surveys. The paper is motivated by the hypothesis that in the beginning of transition in Estonia high labour mobility and low unemployment rate seemed to be related. The analysis reveals that in the end of the 1990s labour mobility has decreased substantially in Estonia compared to 1994. The results from the paper indicate that unemployment rate and labour mobility measure have inverse relationship, both in aggregate and disaggregate level. The most mobile groups in Estonian labour market are Estonians, people living in the area of capital Tallinn and people with higher education. Young people also tend to move a lot from job to job. High mobility in case of young workers is accompanied by high number of unemployment incidents, which is captured by the aggregate unemployment rate time series.

Testing the efficiency of emerging markets: the case of the Baltic States Virmantas Kvedaras Olivier Basdevant There is little evidence on the efficiency of the early stage of the capital market in transition countries, although market structure developments and the learning process could define the framework for efficient markets. The article tries to find out whether financial markets are efficient in the three Baltic States and if not, whether there are any signs of evolving to the efficient capital market. To answer these questions the analysis combines the methodology for testing the efficiency of capital market using the variance ratio robust to heteroscedasticity with the state-space representation, which enables us to use an efficient filtering technique - the Kalman filter - to get time varying autocorrelations. The official Estonian, Latvian, and Lithuanian stock exchange market indices TALSE, DJRSE, and LITIN comprising the most liquid parts of the stock market in a respective country are analysed. The main conclusion to be drawn from the analysis is that financial markets in the Baltic States are, with some turbulence, approaching weak form of efficiency.

Reservation wages in Estonia Marit Hinnosaar This paper analyses the factors determining reservation wages in Estonia, and estimates the influence of the reservation wage on unemployment duration. According to estimations there is no statistically significant effect of unemployment benefit and social assistance on the reservation wage in Estonia. While evidence was found, that the higher the reservation wage, the lower the probability of finding a job, if all other things are equal. It was also found that the eligibility of unemployment benefit or social assistance increases the duration of the unemployment period, which indicates the lower offer arrival rate in the case of unemployed receiving assistance, which might be caused by a lower search intensity.

Nominal and real convergence in Estonia: the Balassa- Samuelson (Dis)connection Balazs Egert The objective of the paper is to analyse the nominal and real convergence process in Estonia drawing on the Balassa-Samuelson ( B-S) framework. A 15-sectoral breakdown for GDP and a 5-digit level CPI data disaggregation with over 260 items is used for the period 1993:Q1 to 2002:Q1 to show that the productivity differential is related to the GDP-deflator relative price of non- tradable goods in the long run. Furthermore, the role of regulated prices in the CPI basket is also investigated - we show that excluding regulated prices makes it possible to detect a robust relationship between productivity and the relative price of market services in CPI. The B-S effect could have possibly contributed to CPI by a yearly average of 2-3% over the sample period, and more specifically 1-4% at the beginning of the period and 0.5-1% in 2000 and 2001. The potential long-run impact of the B-S effect in Estonia is estimated to amount to 1-2%. Analysis of the influence of the B-S effect on the inflation differential and the real appreciation of the exchange rate against Finland, Sweden, Germany and the UK, shows that, whereas the inflation differential attributable to the B-S effect seems to have been higher in the early 1990s, it better explains the real appreciation occurring in recent years.

The impact of minimum wage on the labour market in Estonia: an empirical analysis Marit Hinnosaar Tairi Room In Estonia, as in several other EU acceding countries, minimum wage has been on an upward trend and in the coming years it will expectedly be raised faster than the average wage. Despite its rapid increase, the impact of the minimum wage on Estonian labour market has not been analysed. The current paper aims to fill this gap. We estimate the effect of the minimum wage on employment and wages in Estonia during the period of 1995-2000, using micro-data from Estonian Labour Force Surveys. The estimation results indicate that a minimum wage increase leads to employment reduction for the group of workers who are directly affected by this change, ie those whose wages have to be raised as a result. Additional negative effect of raising the minimum wage is that the rate of compliance with this regulation diminishes as a result, thereby enlarging the share of workers whose salaries remain below the legally set minimum.

The relationship between REER and trade flows in the context of the equilibrium exchange rate Reimo Juks The paper focuses on the time-series analysis of the traditional trade equations. The results from the cointegration, ARDL and Granger causality analyses of trade elasticities cast some doubt on the usefulness of the internal-external balance approach to the equilibrium exchange rate. The long-run impact of the REER on trade flows turned out to be statistically insignificant, being independent of method and specification of the model employed. The latter implies a secondary role for the REER in achieving a sustainable position of external balance. Date: 2003-11-20 URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2003-09&r=all 195. Exchange rate pass-through to Estonian prices Aurelijus Dabusinskas The objective of the paper is to further our understanding of the relationship between changes in the nominal exchange rate and prices in a small open economy. The paper uses data from 1995 Q1- 2003 Q1 for Estonia to investigate the exchange rate pass-through to import, producer and consumer prices, both total and disaggregated. Although the currency board arrangement eliminates exchange rate fluctuations from a very significant share of the Estonian effective currency basket, the remaining variation in the nominal exchange rate can be regarded as exogenous ( determined by the anchor currency), a useful feature when estimating the pass-through. In the case of import unit values, the pass-through tends to be statistically significant for textiles and commodity-type goods, such as petroleum, non-metal mineral products and basic metals. In the case of producer prices, the long-run pass-through is evident in textiles and chemical products. Point estimates of the long-run pass-through to aggregate import and producer prices fall between 40 and 50%, though the precision of these estimates is low. In contrast, no significant exchange rate pass-through is estimated to consumer prices, measured by total CPI or its tradable component.

Automatic fiscal stabilisers in Estonia: the impact of economic fluctatios on general government budget balance Rasmus Kattai Alvar Kangur Martti Randveer The paper discusses the functioning of automatic fiscal stabilisers in Estonia. The aim of the research is to evaluate government budget sensitivity to economic fluctuations and thereby assess the importance of automatic fiscal stabilisers in Estonia. Specifically we are interested in whether the functioning of automatic fiscal stabilisers might under certain circumstances create difficulties for the fulfilment of the Maastricht deficit criterion according to which public deficit is not allowed to exceed the limit of 3% of GDP. The results of our research show that the role of automatic fiscal stabilisers is modest in Estonia. Budgetary sensitivity was approximately 0.35 in the period 1996-2001 - an increase in output gap by 1 percentage point causes a change in the budget balance by 0.35% of GDP. According to that maximum value, the budget\'s reaction was only 1.3% of GDP (while the output gap was -3.9%). A positive implication of this is that Estonia has good chances of holding the budget balance within the requested ceilings. If the output gap reaches -5%, structural deficit may still be 1% of GDP without the actual balance exceeding the 3% deficit boundary.

Lending cycles in Estonia Marten Kress The objective of this paper is to examine possible cyclical patterns in the lending behavior of Estonian commercial banks. Furthermore, the degree of cycle synchronization between the business cycle and the credit cycle and how much one cycle is behind the other in the case of Estonia is of particular interest. The paper uses data from between January 1994 and February 2004 to identify the Estonian business and credit cycles and compare their features. A Markov regime-switching technique was used in dating both business and credit cycles. Variables of interest in terms of the credit cycle include the total amount of loans provided by commercial banks, household loans, corporate loans, and the share of overdue loans in the total portfolio. Both, monthly and quarterly data was utilized to double-check the results and the business cycle was dated using the Industrial Production Index (IPI) and GDP, respectively. The share of overdue loans in the total portfolio appeared to be counter- cyclical as expected. Changes in the IPI seemed to cause changes in corporate loans with a two-quarter lag on average. Asymmetries between the credit and business cycles were found for Estonia. That is, it takes approximately five months from the beginning of an economic slowdown before corporate loans move into a contraction regime. However, it takes approximately eight months for corporate loans to recover their expansionary growth rate. Changes in household loans seemed to precede changes in economic activity by approximately one quarter. URL: http://d.repec.org/n?u=RePEc:eea:boewps:wp2004-03&r=all 198. The importance of the bank-lending channel in Estonia: evidence from micro-economic data Reimo Juks The paper studies the importance of the bank-lending channel in Estonia. The results from the descriptive evidence suggest that there is a significant share of bank dependent borrowers in Estonia, but the impact of a monetary policy shock on the loan supply of banks seems to be ambiguous. The empirical analysis provides evidence in favour of the bank-lending channel in Estonia. First, well-capitalized banks seem to experience a smaller outflow of deposits after a monetary contraction. Second, the liquidity position of banks seems to be an important determinant of the loan supply suggesting that more liquid banks are able to maintain their loan portfolios, while less liquid banks must reduce their loan supply after a monetary policy contraction. This finding is consistent with the evidence for the euro area, where liquidity is also the most important determinant of the loan supply.

Liquidity Constrains and Ricardian Equivalence in Estonia Hannes Kaadu Lenno Uuskula This paper aims to find evidence of the influence of government deficit on private consumption in Estonia. The data only shows some support for Ricardian equivalence. Two approaches were used in the empirical tests. The Haque and Montiel (1989) equation of consumption was estimated using an instrumental variables technique. The Aschauer (1985) system of equations was estimated with the full information maximum likelihood method. Formal tests based on macro data could neither reject nor confirm the existence of liquidity constraints or Ricardian equivalence. There remains a lot of room for testing both of these hypotheses in Estonia. Further efforts to test liquidity constraints should concentrate on using micro data.

Estonian labor market institutions within a general equilibrium framework Marit Hinnosaar The implications of the Estonian labor market policy reforms, such as changes to the minimum wage, social benefits and tax allowance, will be analysed using a simple applied general equilibrium model. The model used in the paper is from Bovenberg et al (2000), with the addition of an efficiency wage section based on Shapiro and Stiglitz (1984). The model integrates union bargaining and efficiency wage theory into a traditional CGE model framework.

Estimating the equilibrium exchange rate of the Estonian kroon Marit Hinnosaar Hannes Kaadu Lenno Uuskula The paper presents empirical estimations of the equilibrium exchange rate of the Estonian kroon. The behavioural equilibrium exchange rate (BEER) approach is used to analyse the dynamics of the real effective exchange rate in the time period from 1995 to 2002. The estimates range from a 15% undervaluation to a small overvaluation of the kroon in the beginning of the period and indicate a position close to equilibrium in 2002.

Describing Fiscal Policy in Central and Eastern European EU Members Rasmus Kattai John Lewis This paper develops a simple framework for describing fiscal policy where policymakers attempt to minimise deviations in output and budget balance from target values. Optimal policy is given by minimising a quadratic loss function subject to a linear structure of the economy. This policy can be viewed as weighted average of two polar cases - the case where the budget deficit adjusts to eliminate any deviations from potential output ( hyperstabilisation), and the case where taxes and spending are determined exclusively by some budgetary goal (hooverism). We find some evidence of stabilisation for Poland, Latvia and Estonia. There is no evidence for the Czech Republic, Lithuania, Slovakia and Slovenia, suggesting that fiscal policy was being used for other objectives. The best fit is for Estonia, suggesting that a strict fiscal policy environment may not be incompatible with stabilising fiscal policy.

Application of investment models in foreign exchange reserve management in Eesti Pank Andres Vesilind Toivo Kuus This paper describes active investment strategy used in the central bank of Estonia and introduces model-based investment decisions as a component of that strategy. The first chapter of the paper describes the evolution of the investment process in Eesti Pank and outlines the framework of reserve management. It describes the role of several forms and styles of investing: active and passive management, qualitative and quantitative management, emphasizing the role of diversification for achieving better performance. The chapter concludes with the description of the investment strategy used in the central bank of Estonia. The second chapter describes model-based investing as part of active management strategy. Three investment models are estimated and tested: a model for directional positions in the US, German and Japanese 10-year government bond futures, a model for cross- currency positions in ten major currencies, and a model for cross- country yield spread trades in eight major government bond markets. The models extend the framework developed by Ilmanen and Sayood (Ilmanen et al. 2002). After the model estimation the models are combined with a trend-following model and the whole set of diversified models is tested. Finally, correlation study of these results with the results of external asset managers and in-bank discretionary analysis is performed. The paper ends with a discussion on the possibilities for further development of the quantitative investment program and conclusions.

Privatizing Higher Education in Spain FRANCISCO MARCOS (Instituto de Empresa) (WP 13/03 Clave pdf)The Spanish university system has witnessed many changes. Initial conditions for competition were laid down in 83, specially through the recognition of legal status to private universities. However, the shortage of students since 98 and the drop on demand for higher education has prompted further reform recently.In 2001 a new act was enacted to force market- like behavior and to privatize some operating conditions of state universities. ItA?s too early to assess the effectiveness of these changes, but public funding remains mostly unchanged and this is a key issue that would need to be modified in order to provide conditions of authentic competition in the higher education.

Cost Accounting in Early Regulated Markets: The Case of the Royal Soap Factory of Seville, 1525-1692 SALVADOR CARMONA (Instituto de Empresa) (WP 16/03 Clave pdf) Regulated markets and state-owned monopolies characterized the economies of many Southern European territories around the end of the Middle Ages and during the Renaissance. Although this economic form was of considerable importance in implementing public policy at the time, investigation into the functioning of cost accounting in such contexts has been consistently neglected in accounting research. In this paper, we examine the role of cost systems in early regulated markets by focusing on the case of the soap production and distribution monopoly in the City of Seville, Spain.

This paper proposes a framework for process modelling of ES. The four steps method involves: Current Situation Analysis, Business Process Improvements and Requirements, Gap Analysis, and To-be process to develop. Outputs of the methodology are an interdependent set of organizational and system proposed changes, and feedback loops to the ES vendors and to the strategy of the firm. In-depth case studies and extensive literature review provides methodological support. For practitioners, this study provides useful insights into one of the reasons by which companies could be frustrated with ES implementation.

Do Moving Average Rules Make Profits? A Study Using The Madrid Stock Market LAURA MARTA NUA‘EZ (Instituto de Empresa) (WP 03/04 Clave pdf) Previous studies have reported mixed results with regard to the success of technical trading rules. Studies that provide positive evidence are [Brock et al (1992), Karjalainen (1994), Bessembinder et al (1995),Mills (1997), and Fernandez et al (1999)]. Studies rejecting the utility of technical trading rules are [Hudson et al (1996) or Allen et al ( 1999)]. A recent body of work has applied evolutionary algorithms to the design of trading rules [see Karjalainen (1994), Allen et al (1999), Fernandez et al (2001) and NuA±ez (2002)].This paper uses genetic algorithms to tests the forecastability of the moving average in the MSE.We report the lack of utility of this indicator.

Trading Costs for Emerging Market Stocks GONZALO CHAVEZ (Instituto de Empresa) ANA CRISTINA SILVA (Instituto de Empresa) We estimate trading costs that include explicit, implicit and opportunity costs. The Lesmond et al. (1999) limited dependent variable model of returns is applied to stocks in Argentina, Brazil, Chile and Mexico. Costs are compared across countries for samples matched by market value. Comparisons are performed while controlling for variations in the economic variables that affect trading costs using regression models [Bessembinder & Kaufman ( 1997)]. We find that trading costs for large and medium firms are significantly higher for Brazil and Mexico than for Argentina and Chile. This result is interesting given that the two former markets are, by far, the most active markets in Latin America.

Argentina presents no significant differences. When we control for stock characteristics, the previous difference disappears for Brazilian and Chilean securities,while it is accentuated for Mexico. Local Mexican stocks are almost 3% of value traded more costly than their corresponding ADRs.Thus,Mexico presents cost barriers that inhibit the implementation of arbitrage transactions that facilitate stock price alignment.

JULIO DE CASTRO (Instituto de Empresa) (WP 07/04 Clave pdf) According to economic theory, under- performing firms should be selected out of the market. However, research shows that these firms persist, often for long periods of time. In this article we explore the non-firm-performance factors that contribute to the decision to persist with an under- performing firm. Using the escalation of commitment literature we identify seven variables that are associated with the persistence decision. We reconcile the economic and psychological views by finding that the extent to which some of these non-firm- performance factors influence the persistence decision is, in part, dependent upon the owner-managersaˆ™ level of extrinsic motivation.

Our paper helps clarify the nature of customer demand for legal versions of products, and gain a deeper understanding of the way that piracy can enhance the performance of those firms that own the intellectual property. We contend that although piracy represents unauthorized imitation of a firmaˆ™s intellectual property, there are some circumstances when piracy can improve the value of the intellectual property.

Hierarchical regression analyses indicated higher satisfaction, lower intentions to exit, and higher perceived fit for owner-managers whose dominant decision- making style complemented the levels of formalization in their firms.The results suggested that owner-managers with intuitive decision-making styles were better fitted to the demands corresponding to less structured firm environments than their analytic counterparts.

A model of enterprise systems capabilities OSWALDO LORENZO (Instituto de Empresa) This study has developed a model of ES capabilities to analyze the extent and quality of the use of ES in organizational contexts. The model consists of six general ES capabilities that can be used and deployed by organizations: 1) transaction automation, 2) decision-making process support, 3) monitoring performance, 4) customer service, 5) coordination, and 6) process management automation. The model itself was initially formulated from concepts in IS and ES literature. Then, the model was applied, validated and tuned through an in-depth case study.

Build-to-order is not that easy: adding volume flexibility to mass customization FABRIZIO SALVADOR (Instituto de Empresa) The present paper reports preliminary observations from a longitudinal case study of the Lawn Mowers & Garden Tractors business unit of Deere & Company. This business unit is interested in analyzing the applicability of a Build-To-Order strategy for its business. By analyzing the problems related to the simultaneous pursuit of volume and mix flexibility we propose a model explaining how these two trade-offs can be simultaneously addressed. We then speculate about the compatibility of the techniques generally advocated to address either volume or mix flexibility, in this case where these two trade-offs have to be jointly reduced.

Fundamentals versus contagion proxies to explain financial assets price changes EVA RAQUEL PORRAS (Instituto de Empresa) There is a general consensus that expected returns are notoriously difficult to predict for many reasons, including modeling and econometric problems. The bubble and contagion literature proposes fundamentals and contagion proxies as explanatory of financial assetA?s price changes. This paper uses mean and semiparametric methods to analyze the explanatory value of some of these variables. The goal of this study is to determine which variables have higher explanatory value as well as their differential impact throughout the distribution of returns. The findings suggest that none of the twelve different models used to proxy fundamentals have any explanatory value for price changes.

An extension of time series tests to panel data EVA RAQUEL PORRAS (Instituto de Empresa) In the financial field much of the data available is in panel form. The objective of this paper is to analyze the long run equilibrium relationship between prices and fundamentals while proposing a very simple method of extending time series models to panel data. This method has several characteristics that make it appealing. First, it is simple to implement. Second, it is general in scope. Third, it takes into account arbitrary correlations. Fourth, it does not require making unrealistic assumptions. Our results are supportive of HanA?s (1996) in that we do not find cointegration between fundamentals and prices.

Form postponement: a reconceptualization FABRIZIO SALVADOR (Instituto de Empresa) Form postponement has been widely acknowledged as one of the main avenues to mitigate the adverse effects of product proliferation or customization on operational performance. As it often happens with long debated concepts, the proposed definitions of form postponement sometimes display substantial differences. This paper aims at moving a step forward towards a more precise definition of form postponement in the domain of tangible products. A first result on this way is that form postponement can be referred to physical activities or decisions concerning product differentiation. A constitutive and an operational definition of form postponement with a decision- oriented focus are then proposed Keywords: Postponment, Product Variety, Definition, Literature Review Date: 2004-06 URL: http://d.repec.org/n?u=RePEc:emp:wpaper:wp04-19&r=all 228. Effective product assortment communication: overcoming the "product variety paradox" on the net FABRIZIO SALVADOR (Instituto de Empresa) When a firm offers customized products, variants and options may end up confusing the customer, instead of increasing sales. Recent developments in Information and Communication Technology made available a class of software products, often termed as "product configurators", which appears to offer new solutions to support the sale of customized products. The present paper analyzes the underlying principles on which successful sales configurators have been built. In doing so, the paper attempts a formalization of the mechanisms through which a firmA?s product assortment can be efficiently and effectively presented to the customer.

IT support to product variety management FABRIZIO SALVADOR (Instituto de Empresa) Offering to customers a high variety of products while guaranteeing competitive prices and reasonable delivery times is an ever-increasing necessity for companies. At the same time, the growing technological content of products contributes further to this complexity, introducing new challenges to management. As for any area of company activity, the creativity of software producers has brought about the development of information science systems, such as Product Configuration Systems, Product Data Management systems (PDM) and Customer Relationship Management Systems (CRM), which all promise to alleviate the problems caused by this complexity.

Prospective voluntary agreements to escape carbon lock-in JAVIER CARRILLO (Instituto de Empresa) The paper looks for co-evolutionary policy responses to carbon lock-in - a persistent state that creates systemic market and policy barriers to carbon low technological alternatives. We address the coordination role for authorities rather than the corrective optimisation and analyse experiences from environmental voluntary agreements and foresight activities. The paper argues that combining the virtues of these tools into a new policy tool, named Prospective Voluntary Agreement (PVA), can help facilitate an escape from carbon lock-in and provide policy resources for addressing lock-in related issues.

A taxonomy of business processes LUIS EDUARDO SOLIS (Instituto de Empresa) ANGEL ANTONIO DIAZ (Instituto de Empresa) OSWALDO LORENZO (Instituto de Empresa) This study aims to gain a better understanding of key business processes. The processes of the firm are analyzed, proposing a classification of eight generic intra-organizational processes, and eleven generic inter-organizational processes, as well as criteria for the determination of the criticality of these processes and key performance indicators. Using these criteria critical intra-organizational and inter-organizational processes are identified in sixteen industrial sectors. Through a better understanding of key processes and network relations enterprises can develop competitive advantages that leverage their survival and well being.

The goal of this paper to test whether cointegration exists between the stock market index of each of the mentioned developing nations, and the US stock market. Previous studies have shown that unit roots occur in stock price series.

We empirically test the relationship among strategic quality planning, supplier- based relationships, and some TQM practices such as product design, product innovation, dependable deliveries, and value-to- customer quality and organizational performance. The findings suggest that the success of some TQM practices may be buoyed by over-lapping supply chain principles such as supply chain management strategy. Other positive relationships described in the literature such as that between strategy, TQM principles, and organizational performance, are again confirmed.

Clarifying leadership roles in ERP implementation projects JOSE MANUEL ESTEVES (Instituto de Empresa) Existence of an adequate project champion role has been identified as a critical success factor in Enterprise Resource Planning (ERP) implementation projects. However, the figure of the project champion is not yet quite well understood. Some authors relate it with the project sponsor figure while others relate it with the project manager figure. This paper tries to clarify these concepts. Our research framework is based upon an extensive ERP literature review and a web survey. The findings of this web survey suggest that the adequate project champion role is that of the project sponsor, emerging as a dual-role champion.

Determinants of corporate anti-takeover provisions JUAN SANTALO (Instituto de Empresa) In this paper I study empirically the industry and firm characteristics that determine the level of corporate antitakeover protection. I find that the level of antitakeover protection is negatively associated with the level of firm- specific organizational capital and with stock market volatility. On the other hand, firms that allow a larger degree of antitakeover protection to their managers do indeed invest more in long term projects and operate in more concentrated industries. All these findings are consistent with a managerial entrenchment interpretation of corporate antitakeover provisions.

Implementing and improving the SEI risk management method in a university software project JOSE MANUEL ESTEVES (Instituto de Empresa) Although risk management approaches appeared more than one decade ago, there is the evidence of low penetration rate of their techniques in software projects. One of the most known methods is the SEI Software Continuous Risk Management (SEI-CRM) method. This paper addresses the usage of the SEI-CRM method in a big software development project. The study we carried out suggests that SEI-CRM is limited in terms of the organizational risk perspective. This research is expected to contribute with the knowledge on risk management for software development projects by for which we propose to extend the SEI-CRM method with some organizational risk factors that we have found relevant from our study.

The problem of variable selection for financial distress: applying GRASP methaeuristics LAURA MARTA NUA‘EZ (Instituto de Empresa) We use the GRASP procedure to select a subset of financial ratios that are then used to estimate a model of logistic regression to anticipate financial distress on a sample of Spanish firms. The algorithm we suggest is designed "ad-hoc" for this type of variables. Reducing dimensionality has several advantages such as reducing the cost of data acquisition, better understanding of the final classification model, and increasing the efficiency and the efficacy. The application of the GRASP procedure to preselect a reduced subset of financial ratios generated better results than those obtained directly by applying a model of logistic regression to the set of the 141 original financial ratios.

More politics for less organisation: AristotleA?s social theory JUAN LUIS MARTINEZ (Instituto de Empresa) There is a lack in analysing Third Sector from a philosophical perspective. It is very complicated to answer many questions that are arising: Why men are concerned to the problems other men are involved in? Which is the driving force of the Social Sector? Why are NGOs legitimated to support social matters? What have NGOs to do in the XIX century? This questions need to be answered to fix correctly future strategy, mission and objectives. It is necessary to build an ethical-political frame to understand how Third Sector works.

An institutional sociology perspective of the adaptation of activity based costing by spanish health SCOTT DOUGLAS ERIKSEN (Instituto de Empresa) Per institutional sociology hospitals will respond to external environmental pressures and adopt Activity-Based-Costing (ABC). This theory overemphasizes conformity and failures to consider the advantages of organizational non-conformance. A conflict of interests between physicians and management leads to physician resistance of accepting ABC. This paper investigates the Spanish governmentA?s response to this resistance by creating new public foundation hospitals, and involves a case study of foundation hospital AlcorcA?n.

The why, when, and how of Corporate Social Responsibility JUAN LUIS MARTINEZ (Instituto de Empresa) Reflecting on the question of who is the principal subject of social responsibility in the business sphere, Greenfield sets out a number of common assumptions among practitioners in the field and tries to dismantle them through a critical review of recent literature. Some of his reflections need to be nuanced from an ethical basis and elaborated upon from a practical point of view. Taking as our starting point GreenfieldA?s conclusion "there is no such thing as business ethics, only ethics of individual business men and women", this article aims to look in more depth at the consequences of regulating personal ethics and referring it to an institution.

Corporate Governance and environmental firm performance JUAN SANTALO (Instituto de Empresa) CARL KOCK (Instituto de Empresa) >From a reactive, antagonistic stance towards environmental regulations, many firms have evolved to act in a pro-active fashion to integrate environmental issues into their core strategies. Using measures of different corporate governance instruments that proxy for the ability of managers or shareholders to implement their strategic preferences we demonstrate empirically that shareholders are indeed laggards because they lower firm environmental performance while the latter actually has positive effects on firm financial performance. Managers, however, push for better environmental and hence financial performance and thus act against shareholders preferences, but in their interest.

The Dominance of Diversified Versus Specialized Firms Across Industries MANUEL BECERRA (Instituto de Empresa) JUAN SANTALO (Instituto de Empresa) Some industries are populated primarily by diversified firms, while other industries are dominated by specialized firms, which are present only in such a given industry. In this study, we analyze what factors determine the dominance of diversified versus specialized firms, and its effect on firm performance. In line with transaction cost economics, we show that market concentration and the degree of variability in the diversification pattern of firms in the industry are negatively associated with the importance of the activity accounted by specialized firms across the 720 industries in our study.

This result affects the risk-averse investorA?s choice of contracts.Unlike previous results, the purely risk-sharing contract is now shown to be suboptimal.Using numerical methods we show that under optimal linear contract, managerA?s share in the portfolio return is higher than what it is under a purely risk sharing contract Keywords: Linear performance-adjusted contracts, Short-selling constraints, Third best effort Date: 2005-01 URL: http://d.repec.org/n?u=RePEc:emp:wpaper:wp05-07&r=all 250. An International Capm With Consumption Externalities And Non-Financial Wealth JUAN PEDRO GOMEZ (Instituto de Empresa) We study an international asset pricing model where agents have preferences defined over their own consumption as well as the contemporaneous average or per capita consumption in their own country. These have been termed "keeping up with the Joneses" preferences. In the presence of non-diversifiable non-financial wealth, the model predicts that portfolio holdings of the representative investor differ across countries. In equilibrium we show that this gives rise to a multifactor CAPM where, together with the world market price of risk, there exists country-specific negative prices of risk associated with deviations from the countryA?s average consumption.

A Multidimensional Unfolding Latent Trait Model For Binary Data ALBERTO MAYDEU (Instituto de Empresa) We introduce a multidimensional latent trait model for binary data with non-monotone item response functions. We assume that the conditional probability of endorsing an item is a normal probability density function, and that the latent traits are normally distributed. The model yields closed form expressions for the moments of the multivariate Bernoulli (MVB) distribution. As a result, cell probabilities can be computed also in closed form, regardless of the dimensionality of the latent traits. The model is an ideal point model in the sense that a respondent - precisely at the ideal point (the mode of the item response function)- endorses the item with probability one.

Limited Information Goodness-Of-Fit Testing In Multidimensional Contingency Tables ALBERTO MAYDEU (Instituto de Empresa) We introduce a family of goodness-of-fit statistics for testing composite null hypotheses in multidimensional contingency tables of arbitrary dimensions. These statistics are quadratic forms in marginal residuals up to order r. They are asymptotically chi- square under the null hypothesis when parameters are estimated using any consistent and asymptotically normal estimator. We show that when r is small (r = 2) the proposed statistics have more accurate empirical Type I errors and are more powerful than PearsonA?s X2 for a widely used item response model. Also, we show that the proposed statistics are asymptotically chi-squared under the null hypothesis when applied to subtables.

Existing literature emphasizes the role of market power, determined by market size, in analyzing international regulatory influence. While we do not contest the importance of market power, we introduce the notion of domestic regulatory capacity to capture the domestic institutional side of international market regulation that previous work has sidestepped. Domestic regulatory capacity is the missing link between latent market power vested in market size and international influence activated through regulatory institutions.

Benevolence Based Trust And Agency Relations Among Upper Echelons Of Family-Owned Firms MANUEL BECERRA (Instituto de Empresa) CRISTINA CRUZ (Instituto de Empresa) We investigate how the family status of owners, CEO, and top management team (TMT) determine CEOA?s perceptions regarding the benevolence of his/her TMT and how in turn these perceptions of benevolence-based trust influence the nature of TMT control and incentive mechanisms. Using a sample of 122 Spanish firms, we find that CEOsA? assessment of TMT benevolence in family firms is more positive when (a) the CEO is a family member and the family is in a stronger ownership position; (b) there is greater similarity in family status between CEO and top managers and (c) environmental turbulence is low.

JUAN SANTALO (Instituto de Empresa) CARL KOCK (Instituto de Empresa) This paper brings two important topics of corporate environmental management and corporate governance by exploring the impact of various governance mechanisms on the level of environmental performance that is realized by firms. We hypothesize that anti-takeover amendments and provisions that restrict managersA? personal liability create a sphere of "bad" discretion that allows managers to shirk by underinvesting in potentially financially beneficial levels of environmental performance. We suggest that corporate governance structures that emphasize higher levels of performance pay and lower degrees of monitoring create a degree of "good" discretion that enhances environmental firm performance.

La transformaciA?n del sector profesional FRANCISCO MARCOS (Instituto de Empresa) El presente trabajo analiza los principales cambios acaecidos en el sector profesional en los A?ltimos aA±os, deteniA©ndose especialmente en las cuestiones que el aumento en el nA?mero de profesiones y colegios suscita en el plano conceptual, asA­ como en las circunstancias que, en teorA­a, justifican una aproximaciA?n diferente a las prestaciones profesionales ( asimetrA­a informativa y externalidades) en comparaciA?n con otros servicios empresariales. No obstante lo anterior, se observa una creciente mercantilizaciA?n de la actividad profesional, que se ha modernizado y evoluciona empujada por las mismas fuerzas que el resto de las actividades empresariales.

La economA­a funeraria: demanda y oferta en el mercado de servicios funerarios FRANCISCO MARCOS (Instituto de Empresa) (WPE 18/03 Clave pdf) La muerte y lo que la rodea no resulta nada atractiva. Esta circunstancia afecta de modo inexorable a las condiciones de contrataciA?n en el mercado de los servicios funerarios. Los condicionantes emocionales, religiosos y culturales afectan poderosamente al juego de las fuerzas de mercado en este sector y lo singularizan respecto de otros mercados caracterizados por la asimetrA­a de informaciA?n entre los contratantes y la inferioridad del consumidor, proporcionando un escenario de posibles abusos y fraudes. El presente trabajo analiza las caracterA­sticas de la demanda, la oferta y otras variables relevantes (precio y calidad) en el mercado de servicios funerarios. Keywords: Calidad, Demanda, Mercado de servicios funerarios, Precios Date: 2003-11 URL: http://d.repec.org/n?u=RePEc:emp:wpaper:wpe03-18&r=all 266. ValoraciA?n de Empresas TecnolA?gicas mediante Opciones Reales CONCEPCION MARTIN (Instituto de Empresa) (WPE 05/04 Clave pdf) Las empresas tecnolA?gicas incluyen las de la nueva economA­a y aquellas cuya base de negocio es el I + D. El objetivo de este trabajo es evaluar y determinar cuA?les son los mA©todos mA?s adecuados de valoraciA?n para empresas tecnolA?gicas. En concreto, mediante la aplicaciA?n prA?ctica a una tecnolA?gica espaA±ola, se analizan cuA?les son los cambios necesarios de realizar para aplicar los mA©todos de valoraciA?n tradicionales a este tipo de empresas y la validez del enfoque de opciones reales como mA©todo mA?s adecuado para valorar este tipo de empresas. En este sentido, se concluye que valorar las empresas tecnolA?gicas implica identificar y valorar las opciones reales.

La gestiA?n de la confianza como elemento clave para la generalizaciA?n del comercio colaborativo RICARDO PEREZ (Instituto de Empresa) Este documento plantea un modelo de convergencia entre la gestiA?n de la confianza, elemento clave para la colaboraciA?n entre empresas; la incorporaciA?n de los servicios web a la gestiA?n de datos entre empresas y el comercio colaborativo. Dicho modelo, que se apoya en el trabajo de campo realizado con una compaA±A­a que aplica actualmente servicios web en el entorno de comercio, aporta una visiA?n integrada de la literatura tradicional de sistemas inter- organizacionales y una tecnologA­a emergente que es relevante para un futuro desarrollo empA­rico.
