Los partidos políticos y el sistema político colombiano

El artículo revisa el concepto de partido político e intenta responder la pregunta de si existe o hace falta un sistema de partidos en Colombia y de qué tipo. Se parte de que hay una crisis del actual sistema político colombiano que tiene como una de sus causas la fragilidad institucional y democrática de los partidos y lo difuso del sistema de partidos. También se presenta una revisión de las reformas que a partir de 1991 han querido afectar el sistema de partidos y se plantean las posibles razones por las cuales nunca han funcionado estos esfuerzos por mejorar el sistema político.-----This article goes through the concept of political party and intends to answer the question whether it exists or is necessary a system of political parties in Colombia and what type. It begins with the actual crisis of the Colombian political system, and one of its causes is the institutional fragility and the democracy of the parties, and the diffuse of the political parties system. There is an inspection of the reforms that from 1991 have wanted to affect the political parties system, considering the possible reasons of why the efforts to establish a better political have never worked.

Modeling the monetary policy reaction function of the colombian central bank

This paper proposes a simple Ordered Probit model to analyse the monetary policy reaction function of the Colombian Central Bank. There is evidence that the reaction function is asymmetric, in the sense that the Bank increases the Bank rate when the gap between observed inflation and the inflation target (lagged once) is positive, but it does not reduce the Bank rate when the gap is negative. This behaviour suggests that the Bank is more interested in fulfilling the announced inflation target rather than in reducing inflation excessively. The forecasting performance of the model, both within and beyond the estimation period, appears to be particularly good.

Ownership structure and risk at Colombian banks

The separation between ownership and the control of capital in banks generates differences in the preferences for risk among shareholders and the manager. These differences could imply a corporate governance problem in banks with a dispersed ownership, since owners fail to exert control in the allocation of capital. In this paper we examine the relationship between the ownership structure and risk for Colombian banks. Our results suggest that a high ownership concentration leads to higher levels of risk.

Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

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.

The persistent colombian conflict bubnational analysis of the duration of violence

The growing empirical literature on the analysis of civil war has recently included the study of conflict duration at the cross-country level. This paper presents, for the first time, a within-country analysis of the determinants of violence duration. I focus on the experience of the Colombian armed conflict. While the conflict has been active for about five decades, local violence ebbs and flows and areas experiencing continuous conflict coexist with places that have been able to resile and where violence is mostly absent. I examine a wide range of factors potentially associated with violence duration at the municipal level, including scale variables, geographical conditions, economic and social variables, institutions and state presence, inequality, government intervention, and victimization variables. I characterize a few variables robustly correlated with the persistence of localized conflict, both across specifications and using different econometric models of duration analysis.

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.

A firm-level analysis of ICT adoption in an emerging economy: evidence from the colombian manufacturing industries

This study examines ICT adoption among 3,759 Colombian manufacturing firms, and attempts to identify the factors that are conducive to the adoption and usage of ICT at the firm level. Our major findings are (i) that the adoption of a given information and communication technology is better facilitated when a firm is relatively large, has large human capital, engages in more innovative activities, and when a firm’s organizational structure is better aligned with the given technology; (ii) that positive associations between the key determinants and ICT adoptions are more pronounced for small and medium-sized firms than for large ones, and (iii) that information spillovers within industries is also a determinant of ICT adoptions by the firms.

Do Colombian students underestimate higher education returns?

We analyze the determinants of subjective returns of higher education in Colombia. The information on expectations has been collected in categories, motivating the use of interval regression and an ordered probit approaches for modeling the relationship between beliefs and measures of ability, conditioning on individual, school and regional covariates. The results suggest that there are considerable differences in the size of the expected returns according to some population groups and a strong dominance of college against technical education. Gender gaps disappear in college education but it is found that girls tend to believe that professional wages are more concentrated into higher income categories than boys. Finally, it seems that Colombian students overestimate the pecuniary returns to education.

Echoes of the crises in Spain and US in the Colombian labor market : a differences-in-differences approach

This paper presents evidence of the effect of the recent phases of the business cycle in Spain and United States, proxied by their respective unemployment rates, on the labor market of Colombian cities with high migration tradition. These countries are the main destination for labor Colombian migrants. Using information from the household survey between 2006 and 2011 for urban areas in Colombia and a differences-in-differences approach we find that unemployment rates of those countries negatively affect the probability and the amount of remittances received by Colombian households living in areas with high and moderate migration tradition. At a second stage we provide evidence that unemployment rates of those countries positively affect the labor force participation decisions in Colombian regions with the highest migration tradition.

Health insurance as a strategy for access : Streamlined facts of the Colombian Health Care Reform

La reforma colombiana al sistema de salud (Ley 100 de 1993) estableció, como estrategia para facilitar el acceso, la universalidad de un seguro de salud que se adquiere mediante la cotización en el régimen contributivo o mediante la afiliación gratuita al régimen subsidiado, con la meta de cubrir a toda la población con un plan de beneficios único que comprende servicios de todos los niveles de atención. En el documento se analizan los principales hechos estilizados de la reforma en cuanto a cobertura del seguro y acceso y, mediante modelos logit, se estiman los determinantes de la afiliación y del acceso, con datos de las encuestas de calidad de vida de 1997 y 2003. Se destaca que la cobertura pasó del 20% de la población en 1993 al 60% en 2004, aunque parece imposible alcanzar la universalidad; la estructura y evolución de la cobertura muestran que los dos regímenes son complementarios, de modo que mientras el contributivo tiene mayor presencia en las ciudades y entre la población con empleo formal, el subsidiado tiene mayor peso entre la población rural y con bajos niveles de ingresos; por otra parte, el seguro tiene ventajas para la población subsidiada, con una mayor probabilidad de utilización de servicios, aunque el plan es inferior al del contributivo y existen barreras para el acceso.
