Working Papers on Economics

The paper examines the bidders behaviour in the Colombian government bond auctions during 2007 for the period in which there is no uncertainty in the supply. Three main findings are presented. First, in contrast with other treasury auctions (Castellanos [2]), the market clearing price in the…

To date, there is still great controversy as to which exchange rate model should be used or which monetary channel should be considered, when measuring the effects of monetary policy. Since most of the literature relies on structural models to address identification problems, the validity of…

Single-sex classes within coeducational environments are likely to modify students' risktaking attitudes in economically important ways. To test this, we designed a controlled experiment using first year college students who made choices over real-stakes lotteries at two distinct dates. Students…

We examine the effect of single‐sex classes on the pass rates, grades, and course choices of students in a coeducational university. We randomly assign students to all‐female, all‐male, and coed classes and, therefore, get around the selection issues present in other studies on single‐sex…

In this paper we investigate the impact of rapid credit growth on ex ante credit risk. We present micro-econometric evidence of the positive relationship between rapid credit growth and deterioration in lending portfolios: Loans granted during boom periods have higher probability of default than…

Based on the counting of Help-wanted advertisements in print newspapers, we present national vacancy indexes and vacancy rates for Colombia. These series will allow tackling a myriad of questions related to the functioning of the labor markets in emerging economies, where such datasets were not…

In this paper we study the structural determinants of differentials in unemployment rates and labour markets’ performance for colombian cities.

This document analyzes the macroeconomic effects of a boom in a small-open economy’s natural-resource sector. We study the effects of this shock on the most important macroeconomic variables, the resource reallocation across sectors and on welfare under alternative fiscal rules. We employ a DSGE…

Using a three-equation New Keynesian model we find that incorporating an escape clause (EC) into Forward Guidance (FG) is welfare improving as it allows the monetary authority to avoid cases in which the cost of reduced flexibility is too high. The EC provides the central bank with another…

A maximum likelihood method for estimating the power-law exponent verifies that the positive and negative tails of the Colombian stock market index (IGBC) and the Colombian peso exchange rate (TRM) approximate a scale-free distribution, whereas none of the heavy tails of a local sovereign…

Informational constraints may turn the Merton Model for corporate credit risk impractical. Applying this framework to the Colombian financial sector is limited to four stock-market-listed firms; more than a hundred banking and non-banking firms are not listed. 

This paper measures the impact of strengthening the security policy on the rural labour market in Colombia by exploiting the structural change in the number of rural seizures. The new policy produced dissimilar effects across gender, age-groups, and types of occupation. For adults, especially…

This paper presents a novel monthly dataset of job vacancies in Bogota between 1960 and 2010. The dataset was constructed by counting the number of help-wanted announcements published in the most important newspaper with national circulation—namely, El Tiempo. We describe the methodology used to…

In this paper, we propose an alternative methodology to determine the existence of credit booms, which is a complex and crucial issue for policymakers. In particular, we exploit the Mendoza and Terrones (2008)’s idea that macroeconomic aggregates other than the credit growth rate contain…

In this paper two new measures of the Colombian output gap and the real neutral interest rate are proposed. Instead of relying only on statistical filters, the proposed measures use semi-structural New-Keynesian models, adapted for a small open economy. The output gap measures presented are in…

This study implements a regular vine copula methodology to evaluate the level of contagion among the exchange rates of six Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico and Peru) from June 2005 to April 2012. We measure contagion in terms of tail dependence coefficients,…

Using data from the 2010 Colombia Demographic and Health Survey and of the National Survey of the Nutritional Situation in Colombia (ENDS-ENSIN), we analyzed the evolution of the height for the Colombian birth cohorts in the period 1946-1992 by ethnic groups defined through self-classification.…

We apply a pair-wise approach to test the law of one price for deposit (lending) rates in Colombia. We find that when banks are of different size deposit rates adjust quickly, suggesting a competitive environment. By contrast, lending rates adjust rapidly when banks are of similar size,…

In this document we use the Expectations Survey conducted monthly by the Central Bank of Colombia during the period of October 2003 – August 2012. We find that exchange rate revaluations were generally followed by expectations of further revaluation in the short run (1 month), but by…
