Working Papers on Economics

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…

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…

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…

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…

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…

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…

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…

Using Add Health, a very comprehensive longitudinal data set of teenagers and young adults in the United States, we estimate a structural dynamic model of the determinants of obesity. In addition to including many of the well-recognized endogenous factors mentioned in the literature as obesity…

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…

Many central banks, particularly in the developing world, aim for exchange rate stability as a macroeconomic goal. However, most are reluctant to relinquish monetary policy autonomy, so they end up operating through both interest rate and foreign exchange interventions. But the use of multiple…

In this paper we expanded the closed economy model by Bernanke and Gertler (1999) in order to account for the macroeconomic effects of an asset price bubble in the context of a small open economy model. During the nineties emerging market economies opened their financial accounts to foreign…

During the 1920s, the Colombian economy experienced the highest rate of growth in its history. The economic reforms of 1923 (the central bank, gold standard, banking legislation, fiscal reorganization), the coffee boom, and the unprecedented influx of foreign capital were the driving forces…

We study …nancial crises in a small open production economy subject to credit constraint and uncertainty on the value of debt repayments. We …nd that the possibility of reducing the severity of future crises encourages the central planner (CP) to increase both the crisis frequency and current…

This paper examines the non-reversal of fortune thesis proposed by Acemoglu, Johnson, and Robinson (2002) in the light of the Colombian experience over the last 500 years. Using a total of 14 national population censuses and the record of tributary Indians in 1559, it is found that the…

A regular vine copula approach is implemented for testing for contagion among the exchange rates of the six largest Latin American countries. Using daily data from June 2005 through April 2012, we find evidence of contagion among the Brazilian, Chilean, Colombian and Mexican exchange rates.…

The history of economic recessions has shown that every deep downturn has been accompanied by disruptions in the …financial sector. Paradoxically, up until the …financial world crisis of 2007-2009, little attention was given to macroeconomic and …financial interdependence. And, in spite of a…

Using data from Medellín, second largest city in Colombia, we asses in this paper how a set of neighborhood characteristics determines wages and labor supply for workers in the city. We use GIS data to construct measures of the quality of environments where workers live. This paper focuses in…

We study endogenous growth within a model with occupational choice in which innovators produce ideas, within an asymmetric information framework. Each innovator has private knowledge of their production costs. Developers offer innovators non-linear contract schemes that affect both the number of…

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…

In this paper, I estimate the demand for housing in Bogotá, modeling electricity consumption explicitly to take into account the crossed subsidies included in Colombian utility rates. I use household level data on housing prices, observable dwelling attributes, and demographic variables to…
