1. 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.

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.
Keywords: ownership structure, control, control transfers

3. 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.
Keywords: factors shares, returns on capital, privatisations

4. 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.
Keywords: labour supply, program evaluation, temporary contracts,
open-end contracts, shadow economy

5. 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.

6. 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.

7. 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.

8. 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.

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.
Keywords: price dispersion, search models, macroeconomic factor,
time aggregation

10. 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

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.

12. Costos generados por la violencia armada en Colombia: 1993-
2003.
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).

13. ?Se ha liberalizado el comercio de servicios en los
acuerdos comerciales de EEUU? 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.

14. Una propuesta de subsidio al salario para Colombia (version
preliminar).
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.

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.

16. Tratado de Libre Comercio y Barreras No Arancelarias: Un
analisis critico.
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.

17. Educacion y pensiones en Colombia: Una perspectiva
intergeneracional.
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.

19. El modelo DNPension V 4.0 Parte I.
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.

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.

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.

22. 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.

23. 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.

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.

25. 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.

26. 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.

27. Una aproximacion al financiamiento de un sistema de
proteccion social en Colombia
Olga Lucia Acosta
Luis Fernando Gamboa Nino
El documento hace una revision de las principales fuentes de
proteccion social que hay en Colombia y las caracteristicas de
los sistemas de proteccion de otros paises. Se encuentra que
gran parte de lo que se conoce como gasto social se destina al
tema pensional y que los resultados de los fondos de solidaridad
son muy pequenos frente a la autoproteccion de los hogares. Se
propone tener en cuenta los esfuerzos individuales y privados que
hay en Colombia al disenar un sistema de proteccion social,
pues de lo contrario se estarian desincentivando estos esfuerzos.

28. 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.

29. 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.

30. 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.

31. 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.

34. The role of networks in collective action with costly
communication.
Christian R. 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.

35. 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.

36. Politica monetaria y la corte constitucional: el caso del
Salario minimo.
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.

37. 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.

38. 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.

39. 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.

No deja de sorprender que una persona que se precia de haber

componente de otro concepto denominado “la prueba de
razonabilidad”. Estos, constituyen una de las herramientas
conceptuales y teoricas fundamentales del constitucionalismo
moderno, con particular incidencia en el estudio constitucional
de normas de alcance economico1. Esta confesion de culpa la
hago sin mayor pudor, pues tengo la certeza de que mis colegas
economistas podrian, si quisieran, formular el mismo mea culpa.
No me sorprenderia si encontrasemos uno o varios casos
analogos de ignorancia inexcusable entre los abogados.
Apostaria a que muchos de ellos desconocen la existencia
siquiera del concepto de “sostenibilidad fiscal” o de
“funcion de bienestar” y, peor aun, de la relevancia de
estos conceptos para la aplicacion correcta de la Constitucion.
El texto se divide en tres partes. La primera explica la prueba
de razonabilidad. En la segunda se presenta un breve analisis de
algunas sentencias de la Corte para discernir si ha aplicado
dicha prueba y cuales han sido los cambios y efectos de la
jurisprudencia que han generado una reaccion de los economistas.

42. Crisis cambiarias en Colombia bajo tipo de cambio Fijo: 1938-
1967.
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.

46. 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.

47. 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.

48. La prueba de razonabilidad y la estabilidad de las reglas de

Maria Mercedes Cuellar
No deja de sorprender que una persona que se precia de haber
estado involucrada, desde hace muchos anos, en el ejercicio de
la economia publica, desde el gobierno, el Banco Central y la
actividad privada y gremial, como es mi caso, desconociera por
completo la existencia de “el principio de proporcionalidad”,
componente de otro concepto denominado “la prueba de
razonabilidad”. Estos, constituyen una de las herramientas
conceptuales y teoricas fundamentales del constitucionalismo
moderno, con particular incidencia en el estudio constitucional
de normas de alcance economico1. Esta confesion de culpa la
hago sin mayor pudor, pues tengo la certeza de que mis colegas
economistas podrian, si quisieran, formular el mismo mea culpa.
No me sorprenderia si encontrasemos uno o varios casos
analogos de ignorancia inexcusable entre los abogados.
Apostaria a que muchos de ellos desconocen la existencia
siquiera del concepto de “sostenibilidad fiscal” o de
“funcion de bienestar” y, peor aun, de la relevancia de
estos conceptos para la aplicacion correcta de la Constitucion.
El texto se divide en tres partes. La primera explica la prueba
de razonabilidad. En la segunda se presenta un breve analisis de
algunas sentencias de la Corte para discernir si ha aplicado
dicha prueba y cuales han sido los cambios y efectos de la
jurisprudencia que han generado una reaccion de los economistas.

49. 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.

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.

El desarrollo de estrategias industriales tipo cluster, cadenas

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

publicas juegan un papel predominante, puesto que pueden ser
facilitadoras de ambientes economicos favorables articulados

desarrollo de los mismos. El presente trabajo parte entonces de
la identificacion y analisis de las politicas publicas que

53. Mercadeo con causa social: ?Responsabilidad social o
estrategia comercial?
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.

54. 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.

Hertog,D. den (Tilburg University, Center for Economic

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

56. 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.

57. 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.

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.

60. 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.

61. 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 (

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. Classification-

64. 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.

66. 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.

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.

69. Rice Consumption in the United States: New Evidence from
Food Consumption Surveys
Batres-Marquez, S. 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.

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.

This paper examines the economic impact of the second great
immigration wave (1945- 2000) on the US economy. 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.

72. 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.

73. Optimum Income Taxation and Layoff Taxes

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.

74. 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.

75. 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.

76. 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.

77. 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.

78. The Roots of Low European Employment: Family Culture?
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.

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.

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.

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..

82. 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.

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.

84. Parameter Estimation in Semi-Linear Models Using a Maximal
Invariant Likelihood Function
Jahar L. 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.

In the context of a general regression model in which some

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.

Sudden Stops are associated with increased volatility in

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.

This paper examines the current state of the trade policy regime

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.

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.

This paper tests for asymmetries in the preferences of the Euro-

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.

91. 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.

92. 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.

Lucio Valerio Spagnolo, Mario Cerrato (CELPE-DISES,

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.

Alex W. 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.

95. 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.

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 appropriate conception of team outputs is investigated by
estimating a two-output factor demand system for baseball teams,
relative to which single-output models are rejected. There is,
however, some empirical support for output separability,
suggesting that team outputs may sometimes be adequately treated
as a production aggregate.

98. 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.

99. The Neuroeconomics of Trust
Paul J. 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.

100. 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.

101. 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.

102. 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.

104. 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.

105. 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.

106. 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

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.

108. 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..

In this paper we use data from SourceForge.net, the largest open

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.

110. 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.

111. 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.

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?

114. 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.

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.

116. 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.

117. 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.

This paper investigates the degree and nature of economic and

119. 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.

120. 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.

121. 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.

122. 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.

123. 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. We use the implicit function theorem to derive
analytic expressions for the Greeks

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.

125. 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.

126. 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.

127. 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.

128. 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.

129. Subsidy competition in integrating economies.
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.

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.

131. 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.

132. On Robust Trend Function Hypothesis Testing
Harvey, David I; Leybourne, Stephen J; Taylor, A.M. 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.

133. Can Mediation Improve Upon Cheap-Talk? 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.

The paper studies the impact of ambiguity on history-dependant

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.

137. 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.

There are plans by five West African countries to establish a

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.

The paper investigates a climate-economy model with an iso-
elastic welfare function in which one parameter gamma measures
relative risk-aversion and a distinct parameter rho measures
resistance to intertemporal substitution. 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.

147. 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.

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.

Zisimos Koustas (Department of Economics, Brock University)
Jean-Francois Lamarche (Department of Economics, Brock

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.

150. 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.

151. 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.

152. 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.

154. 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.

155. 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.

Isabel Schnabel (Max Planck Institute for Research on

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.

157. 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.

Thomas Gaube (Max Planck Institute for Research on

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.

This paper deals with second-best pollution taxation by

Assuming certain restrictions on utility and that the marginal
revenue from environmental taxation is positive, it is shown that
environmental quality is higher in second best where only
distortionary taxes are used to finance public expenditures than
in the first-best optimum where lump-sum taxes are available.

160. 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.

Douglas C. North (Washington University, St. Louis)
Syed Shariq (Institute for International Studies, Stanford

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.

162. 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.

163. Is there an optimization in bounded rationality? 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.

164. 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.

165. The Role of Rivalry. Public Goods versus Common-Pool
Resources
Frank P. Maier-Rigaud (Max Planck Institute for Research on

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.

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.

167. 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.

are Multidimensional
Martin Hellwig (Max Planck Institute for Research on

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.

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.

170. 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.

171. 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.

Gianluigi Pelloni (University of Bologna)
We develop a generalised impulse response function (GIRF)
approach to explore the different impacts of aggregate and
sectoral shocks within a VAR-GARCH-M model. Using the output of
our GIRF analysis, we explore the behaviour of three European
countries (Germany, Spain and the UK). We analyse the aggregate
and sectoral responses to discriminate among three different
hypotheses of business cycle fluctuations. Links are established
and explanations are provided within the still experimental
character of our exercise.

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.

175. 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

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.

177. 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.

178. 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.

179. 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.

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).

181. 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.

182. 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.

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.

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.

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.

186. 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.

187. 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.

main emphasis is on the need to continue tough fiscal policy in
order to maintain public deficit, as well as to avoid

189. 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.

190. 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.

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.

192. 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.

193. 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.

194. 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.

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

196. 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.

197. 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.

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.

199. 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.

Marit Hinnosaar
The implications of the Estonian labor market policy reforms,
such as changes to the minimum wage, social benefits and tax

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.

202. Hooverism, Hyperstabilisation or Halfway-House? 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.

203. 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.

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.

(WP 16/03 Clave pdf) Regulated markets and state-owned
monopolies characterized the economies of many Southern European

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.

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.

local stocks cost less. 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.

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

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

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.

assumptions. Our results are supportive of HanA?s (1996) in

Form postponement has been widely acknowledged as one of the
main avenues to mitigate the adverse effects of product

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

"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.

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.

230. 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.

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.

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.

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.

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.

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.

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.

241. 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. Population ecology is offered as
an explanation for the emergence of new entities as a result of
inert existing entities resistance to reform.

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.

analyze what factors determine the dominance of diversified

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.

We study delegated portfolio management when the managerA?s

we show that under moral hazard, linear performance-adjusted
contracts do provide portfolio managers with incentives to gather
information.We find that the risk-averse managerA?s effort is
an increasing function of her share in the portfolioA?s return.
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

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.

253. 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.

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.

This paper show that work on international market regulation has
paid insufficient attention to the critical role played by
domestic political and regulatory institutions. 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

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.

265. 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.

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.

267. 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.
