Aproximación al Valor Económico Agregado (Economic Value Added, EVA) en organizaciones públicas.

El presente documento pretende mostrar la aplicación y variación del Valor Económico Agregado (EVA®) en organizaciones del sector público, en cuyo cálculo y análisis se deben tener en cuenta las condiciones específicas de estas organizaciones, tales como la concepción de valor público, en la cual el ciudadano es accionista (shareholder) y a la vez pertenece a varios grupos de interés (stakeholders), los costos de transacción, de agencia, la amplia separación de la propiedad, la mayor influencia de las leyes en la gestión (en especial la financiera), el tipo de bienes producidos y servicios prestados, y el manejo de la información financiera.

Social housing and land use planning in Medellin during the period 2006-2011. Steps towards socio economic and residential segregation

This paper presents an approach to the relationship between land use planning and socioeconomic residential segregation, from the location of social housing in Medellin, Colombia, during the period 2006-2011. The first part introduces the land use regulations regarding the location of social housing, identifying ambiguities in the current spatial plan. Next, we present the intersection of  regulatory information and the location of the projects that were under construction during the  study period, highlighting the need to consider the location as an important characteristic of social housing and residential segregation as a phenomenon that must be recognized and worked on land  use planning in our cities.

Balance de la participación de Colombia en el Pacific Economic Cooperation Council (PECC) entre 1987 y 2005

Colombia posee una ubicación geográfica privilegiada, que le da la opción de entablar relaciones a través de los Océanos Atlántico y Pacífico. Hacia el primero de éstos, se orientan la gran mayoría de esfuerzos relacionados con la consecución de mercados, ubicando a Europa y Estados Unidos.

Labor supply, biased technological change and economic growth

Se utiliza un modelo de innovaciones sesgadas para estudiar los efectos de cambios exógenos en la oferta laboral. En un contexto de innovaciones sesgadas, a medida que las economías acumulan capital, el trabajo se hace relativamente más escaso y más caro, por este motivo, hay incentivos para adoptar tecnologías ahorradoras de trabajo. Del mismo modo un cambio en la oferta laboral afecta la abundancia de factores y sus precios relativos. En general, una reducción de la oferta laboral, hace que el trabajo sea más caro y genera incentivos para cambio tecnológico ahorrador de trabajo. Así, el efecto inicial que tiene el cambio en la oferta laboral sobre los precios de los factores es mitigado por el cambio tecnológico. Finalmente, los movimientos en la remuneración a los factores afectan las decisiones de ahorro y, por lo tanto, la dinámica del crecimiento. En este trabajo se exploran las consecuencias de una reducción de la oferta laboral en dos contextos teóricos diferentes: un modelo de agentes homogéneos y horizonte infinito y un modelo de generaciones traslapadas.

Political intervention in economic activity

This paper proposes a political economy explanation of bailouts to declining industries. A model of probabilistic voting is developed, in which two candidates compete for the vote of two groups of the society through tactical redistribution. We allow politicians to have core support groups they understand better, this implies politicians are more or less effective to deliver favors to some groups. This setting is suited to reproduce pork barrels or machine politics and patronage. We use this model to illustrate the case of an economy with both an efficient industry and a declining one, in which workers elect their government. We present the conditions under which the political process ends up with the lagged-behind industry being allowed to survive.

Telecommunications and economic growth: an empirical analysis of sub-saharan Africa

We examine the effect on economic growth of mobile cellular phones in sub-Saharan Africa where a marked asymmetry is present between land-line penetration and mobile telecommunications expansion. This study extends previous ones along two important dimensions. First, we allow for the potential endogeneity between economic growth and telecommunications expansion by employing a special linear generalized method of moments (GMM) estimator. Second, we explicitly model for varying degrees of substitutability between mobile cellular and land-line telephony, so that greater expansion of mobile telecommunications can have a different impact whenever the level of land-line penetration differs. We find that mobile cellular phone expansion is an important determinant of the rate of economic growth in Sub-Saharan Africa. Moreover, we find that the contribution of mobile cellular phones to economic growth has been growing in importance in the region, and that the marginal impact of mobile telecommunication services is even greater wherever land-line phones are rare. Given the low cost of mobile telecommunications technology relative to other broad infrastructure projects, especially land-line infrastructure, we advocate that mobile telecommunication services be encouraged in the area.

The international economic crisis and the colombian economy

The purpose of this research is to provide an approximation to the likely effects of the crisis on the Colombian economy and to the effectiveness of policy response. For this, the most relevant transmission channels and policy measures are simulated in the setting of a static computable general equilibrium model (CGE). The results obtained are interesting in their own right and are in line with what could be expected given the information available on the behavior of the Colombian economy. Furthermore, they call into question the effectiveness of governmental intervention as judged by its intended countercyclical effects.

Cartoons and economics: general analysis based on colombian economic cartoons

May cartoons be considered as a viable and credible source for the study of economics? There is hardly any research on the subject, even though there is a quite significant amount of cartoons with economic content. This suggests that economics (and economists) have not paid enough attention and do not incorporate in their analysis a relevant primary source. The present paper aims to explore the value of using cartoons as a complementary primary source in economic analysis. We present a way of analyzing economic history through cartoons; first, reviewing cartoons which describe particular historical circumstances and second, examining cartoons that represent generic economic situations and are not necessarily linked to a historical period. We choose 17 cartoons, from different cartoonist, especially Colombian cartoonists that may give us an idea of economic matters and economic history.

Gross Inequality and Inequality of Opportunities in Basic Education: Were they affected by Latin America’s Economic Boom?

In the context of economic growth and recovering socio-economic conditions, many Latin American countries have implemented deep educational reforms since the beginning of the century. This paper aims to analyse whether these changes have promoted equality of educational opportunities in the region. Both the access and knowledge and skills dimensions are evaluated for six important countries, deepening the analysis for Argentina, Brazil and Colombia, in order to better understand the trends observed. Results point to reasonable progress in access, but reflect an unsatisfactory evolution of the level and distribution of knowledge and skills as reflected by PISA test scores.

Economic integration. an overview of basic economic theory and other related issues

Este documento presenta una visión amplia de la Teoría de Integración Económica desde el punto de vista de la teoría de unión aduanera. Se argumenta que dicha teoría carece de integración y que los recientes desarrollos en el tema no parecen resolver esta falla. A pesar de esto, se sugiere que los desarrollos teóricos surgidos a partir del trabajo seminal de Viner y posteriormente desarrollados por otros teóricos, son aún útiles como herramienta de investigación empírica en el tema.

Industrialization and industrial policy in Colombia: a tale of economic development

This paper analyzes the main features and historical factors that played a central role for the industrialization process in Colombia during the twentieth century. The document surveys the legislation and policy instruments used in the programs of import substitution industrialization, nontraditional export promotion, and economic openness

Intention-based economic theories of reciprocity

In recent years, several experiments have shown individuals exhibit authentic reciprocal behaviour in anonymous one-shot interactions. As reciprocity has been shown to be relevant in several economic fields, there have also been several attempts to model reciprocal bahaviour. I review the intention-based models of reciprocity and present an example of teacher management in the public sector in which the government offers an incentive scheme to implement a program. The incentive scheme has a prisoner´s dilemma structure. In both simultaneous and sequential games, equilibrium results may differ from those predicted by standard theory.

Revisiting the Relationship between Income Distribution and Economic Growth

La mayoría de los modelos que exploran la relación entre la desigualdad en la distribución del ingreso y el crecimiento económico, postulan la existencia de una correlación negativa entre las dos que es generada a través de diferentes mecanismos. Paralelamente a los modelos teóricos, un número importante de estudios empíricos han tratado de evaluar esta relación. De este esfuerzo ha surgido un consenso amplio que valida la existencia de dicha relación negativa. No obstante, estudios recientes basados en el uso de datos de panel han producido el resultado contrario, documentando la presencia de una relación positiva entre desigualdad y crecimiento. El examen del debate generado a partir de estos resultados, así como el trabajo empírico adelantado en este estudio, indican que las estimaciones obtenidas en diversos trabajos pueden no ser tan robustas como se creía En consecuencia, se sugiere que la realización de estudios de caso por país puede ser una mejor vía para explorar este tema.

Essays on International trade and economic growth

At present, we are witnessing globalization as a truly worldwide phenomenon. Trade agreements among differing countries, a reduction in trade costs, the mobility of production factors, the free flow of information and so on are all proof of the present day era of globalization. Countries are trading with one another more and more every day and the effects of international trade on economies represent a central discussion in all economic spheres. In spite of increasing trade around the world and the promotion of globalization by multilateral organisms such as WTO and IMF, the effects of international trade are not yet clear. Economics literature concerning the effects of international trade on economic growth and welfare remains ambiguous in terms of both theoretical models and empirical research. The present thesis tries to contribute to the theoretical debate surrounding the effects of dynamic international trade, focusing in particular on the implications for economic growth, welfare and changes in the preferences of individuals.

Economic shocks and crime: evidence from the crash of ponzi schemes

In November 2008, Colombian authorities dismantled a network of Ponzi schemes, making hundreds of thousands of investors lose tens of millions of dollars throughout the country. Using original data on the geographical incidence of the Ponzi schemes, this paper estimates the impact of their break down on crime. We find that the crash of Ponzi schemes differentially exacerbated crime in affected districts. Confirming the intuition of the standard economic model of crime, this effect is only present in places with relatively weak judicial and law enforcement institutions, and with little access to consumption smoothing mechanisms such as microcredit. In addition, we show that, with the exception of economically-motivated felonies such as robbery, violent crime is not affected by the negative shock.
