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…

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.

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…

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…

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 study the relationship between total factor productivity (TFP) and exporting decisions for Colombian manufacturing firms during 2005-2013. We find that productivity increases a firm's probability of being an exporter, and that exporters have higher productivity, with a premium as high as 85…

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…

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…

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…

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…

We study the interdependence between real commodity prices and world real GDP using long-term annual data since 1870, by performing two empirical exercises. First, we compute long-term and medium-term cycles and measure their degree of synchronization for different leads and lags. Second, we…

This paper assesses the efficiency of crop and livestock production in Colombia by using a sample of 1,565 households. The study considers households located in different production systems which differ in geography, climate and soil types. These conditions affect technical efficiency and thus…

Fluctuations in commodity prices are an important driver of business cycles in small emerging market economies (EMEs). We document how these fluctuations correlate strongly with the business cycle in EMEs. We then embed a commodity sector into a multi-country EMEs business cycle model where…

Typically, central banks use a variety of individual models (or a combination of models) when forecasting inflation rates. Most of these require excessive amounts of data, time, and computational power; all of which are scarce when monetary authorities meet to decide over policy interventions.…

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.…
