This document presents a dynamic stochastic general equilibrium model with rule of thumb (Non-Ricardian) agents and both nominal price and wage rigidities. The model follows closely that of Galí et al. (2004) and expands it to include a second way form of heterogeneity (besides the Non-Ricardian…

We study the determinants of sovereign default risk in Colombia by focusing on different time spans of risk which are indicated by yield spreads of government bonds with different maturities. Cointegration regressions are performed to analyze whether the drivers of short-run default risk are…

To evaluate whether transparency is beneficial, it is usual to assume that the central bank may choose one of two options, opacity versus truthful communication. However, the monetary policymaker may have incentives to misrepresent private information so as to reduce economic volatility by…

We analyse three models to determine the conditions under which reserve requirements are used as a part of an optimal monetary policy framework in an inflation targeting regime. In all cases the Central Bank (CB) minimizes an objective function that depends on deviations of inflation from its…

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,…

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

We set a dynamic stochastic model for the interbank daily market for funds in Colombia. The framework features exogenous reserve requirements and requirement period, competitive trading among heterogeneous commercial banks, daily open market operations held by the Central Bank (auctions and…

This paper can be divided into two main parts. The first one, using a simple example by Minford (2004) and Hatcher (2011), gives the reader a basic introduction to understand the comparison between two monetary-policy regimes: Inflation Targeting (IT) and Price-Level Targeting (PLT).

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…

The importance of the banking sector as a key player in interest rate passthrough has been recognized recently in literature concerning monetary policy transmission mechanisms. The interest rate channel, which operates when banks pass on changes in the monetary policy rate to interest rates for…

Financial institutions rate loans as an expression of the risk they believe the client poses. With the data from those ratings, they can evaluate the current quality of their balance sheet and calculate the loan-loss provisions required for their loan portfolio. A loan rating also is an…

Recent months have seen a much larger influx of funds into the Colombian stock market. For example, pension fund mangers (PFM) added Col$5.84 trillion (t) to their stock market investments between 2002 and 2006 (Financial Market Superintendent, 2007), and foreign portfolio investments (short and…

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…
