Working Papers on Economics

This paper analyzes the effect of social security and lump sum layoff payment in an economy with an informal sector and savings, where the search effort is unobserved. I characterize the optimal consumption/search/non-participant strategy assuming that workers are risk averse and that formal…

This paper analyzes efficiency in an economy with an informal sector that consists of unregulated self-employment, and where there are no costs of being informal, (Albrecht et al. (2009)). First, assuming workers in the formal sector are ex-ante heterogeneous, I show that this type of economy is…

This paper evaluates the impact of Resolution CREG 051 on the performance of the electricity markets in Colombia. We found out that productive efficiency has improved since the introduction of the Resolution, that is, the total costs of producing electricity have been reduced. This shows a…

R&D intensity for small firms is high and persistent over time. At the same time, small firms are often financially constrained. This paper proposes a theoretical model that explains the coexistence of these two stylized facts. It is shown that self-financed R&D investment can distort…

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…

Together with a set of not commonly reported ones, the most widely known stylized facts of high frequency Nominal Exchange Rates in Brazil, Chile, Colombia, Mexico, and Peru with respect to the US Dollar are studied and interpreted to the light of recent literature in this paper.

Determinants of consumer credit are estimated by using information from a Credit Union located in Medellín-Colombia. To the best of our knowledge, this is the first investigation using this kind of data in Colombia. We find that life cycle-permanent income hypothesis (LC-PIH) related variables…

This work uses readily accessible data about the stocks of unemployed workers, labor force and duration of unemployment to measure the job finding and separation rates for Colombia from 1984 to 2014. It also evaluates the relative contribution of these rates to the fluctuations of unemployment…

Inglés: We propose a maximal covering location problem with a budget constraint to determine the optimal location of facilities that provide fast police assistance to homicide hot spots, to mitigate criminal activity in Medellín (Colombia). We use the Google Maps Application Programming…

Inglés: In spite of the increasing evidence that has revealed that early access to financial services has long-term impacts, children and adolescents continue to face major obstacles to be financially included, particularly in the developing world. This document presents the main results of a…

This document explores an alternative strategic asset allocation framework for foreign exchange reserves, whose main purpose is to maximize the risk-adjusted returns maintaining the objectives of liquidity and safety of a foreign reserves’ portfolio.   The overall portfolio can be…

This paper has as main objective to build a composite metric of financial soundness for the private corporate sector in Colombia. Instead of relying on the individual and sometimes restrictive financial ratio analysis approach, the purpose of this document is to provide a single metric aimed at…

The paper presents a global model for analysis and projections. The model features a handful of elements that make it suitable for analyzing three broad sets of topics; first, systemic risk and its transmission to country risk premiums; second, the transmission from country risk premiums to…

We use experimental data of a training program in 2005 in Colombia. We find that even up to ten years ahead, the JeA program had a positive and significant effect on the probability to work in the formal sector, and to work for a large firm. Applicants in the treatment group also contributed…

We present a stochastic frontier model with random inefficiency parameters which is able to capture the influence of risk-taking on bank efficiency and that distingues those effects among banks with different characteristics. Cost and profit efficiency are found to be over- and underestimated…

Many central banks that have opted for monetary autonomy have also been reluctant to relinquish control over the value of their currencies. As a result, they have operated through both interest rate and foreign exchange interventions.  However, in the context of the monetary trilemma, both…

This paper analyzes the role of the Great Depression and protectionism in the Colombian industrialization of the early 1930s as well as the role of other determinants in the rapid industrialization that took place during the period 1934-1953. We conclude that the market pushed industrialization…

This  paper  uses  the  Colombian  National  Health  Survey  to  analyze  the relationship between education and risky health behaviors, namely smoking, heavy drinking, being obese, and unsafe sexual behavior, by estimating the education gradient…

Can technological misallocation generate financial frictions? We build a theoretical model with testable implications, in which the misallocation between R&D and production activities generates borrowing constraints. The investor offers the innovator a rent that is contingent to the success…

In this paper we formulate a dynamic multi-unit auction model to characterize bidding behavior in hydro power dominated electricity markets. Our model implies that, in order to maximize expected profits, hydro producers will submit bid prices above its marginal production costs that account for…
