Counterparty risk is an important determinant of corporate credit spreads. However, there are only a few techniques available to isolate it from other factors. In this paper we describe a model of nancial networks that is suitable for the construction of proxies for counterparty risk. Using…

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…

Fifth Summit Meeting of Central Banks on Inflation Targeting “Global Liquidity, Capital Flows and Policy Coordination” organized by Banco Central de ChileSession IV: Policy Responses to Exchange Rate Pressure Stemming from Capital Flows

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…

Presentation titled "Has Monetary Policy Changed? How the Crisis Shifted the Ground under Central Banks", delivered during the Seminar of the EEP Journal (Essays on Economic Policy), organized by Banco de la República at the Events Center of Biblioteca Luis Ángel Arango in Bogotá, Colombia.

Presentation titled "On the Design of Public Institutions: Evidence from Financial Supervision", delivered during the Seminar of the EEP Journal (Essays on Economic Policy), organized by Banco de la República at the Events Center of Biblioteca Luis Ángel Arango in Bogotá, Colombia.

This paper uses the first wave of the Colombian Longitudinal Survey (ELCA) to analyze the relationship between individual health status and labor force participation. The empirical modeling strategy accounts for the presence of potential endogeneity between these two variables.

In this paper we set up a small open economy model with financial frictions, following Curdia and Woodford (2010)’s model. Unlike other results in the literature such as Curdia and Woodford (2010), McCulley and Ramin (2008) and Taylor (2008), we find that optimal monetary policy should not…

This paper provides evidence of short-run predictability for the real exchange rate by performing out-of-sample tests of a forecasting equation which is derived from a consumption-based asset pricing model. In this model, the real exchange rate is predictable as a result of the implications of…

A small open macroeconomic model, in which an optimal interest rate rule emerges to drive the inflation behavior, is used to model inflation within an inflation targeting framework. This set up is used to estimate the relationship between commodity prices shocks and the inflation process in a…

The aim of this paper is to explore firms wage adjustment practices in the Colombian formal labor market; specifically, the timing and frequency of wage increases, as well as the link between wage and price changes. To this end, we use an ad hoc survey of 1,305 small, medium and large firms…

This paper studies the behavior of the survival function of accruing loans during the slowdown experienced by the Colombian economy between January-2008 and March-2009 as documented by Alfonso et al. (2013). We use a dataset with information of different vintage loans between July-2007 and March…

In this paper we survey prominent theories that have shaped the literature on sterilized foreign exchange interventions. We identify three main strands of literature: 1) that which advocates the use of sterilized interventions; 2) that which deems sterilized interventions futile; and 3) that…

This paper presents the construction of a tailor-made Macro Computable General Equilibrium Model for the Colombian economy that satisfies Banco de la República's macroeconomic programming and forecasting interests. Using information on the national accounts divulged by the National Statistics…

We study the effect of shocks to the United States government bonds term premium on Latin American government bonds term premia. For doing so, we compute dynamic multipliers. Our main findings indicate that Latin American countries’ term premia respond permanently to changes in United States…

Our research seeks to determine the impact on female labor outcomes of the amendment on the Colombian labor law in which maternity leave was extended from 12 to 14 weeks (through Law 1468 of July 2011). To identify this impact we compare labor market outcomes of two groups of women with…

The sudden collapse of oil prices poses a challenge to inflation targeting central banks in oil exporting economies. This paper illustrates that challenge and conducts a quantitative assessment of the impact of permanent changes in oil prices in a small and open economy, in which oil represents…
