This document presents how to estimate and implement a structural VAR-X model under long run and impact identification restrictions. Estimation by bayesian and maximum likelihood methods is presented. Applications of the structural VAR-X for impulse response functions to structural shocks,…

Levels of interest rates below historical norms may have enhanced financial instability in developed and developing economies during the 2000's. The risk taking channel of monetary policy transmission is a recent theory that explains the interaction between risk perceptions of the financial…

In the past decade the Colombian Economic Authorities undertook a series of measures that reduced the structural fiscal deficit, decreased the Government currency mismatch and deepened the local fixed-rate public bond market. This paper presents some evidence suggesting that these improvements…

In this paper we show the importance of subject of degree in explaining the gender wage gap in Colombia. In order to minimize the influence of gender differences in experience, promotions, and job changes on the wage gap, we focus on college graduates who have a formal job and who have been in…

This paper propose indicator variables for the implementation of monetary policy in an inflation targeting regime. Using constant interest rate projections, the notion of a target-compatible interest rate is presented. This variable allows to extract some characteristics that the expected future…

We estimate a non-parametrical Capital Asset Pricing Model (CAPM) and find strong evidence rejecting the classical linear CAPM. Furthermore, we find inconsistent linear betas for a series of stocks in the Colombian stock exchange (BVC), supporting the hypothesis of a better and consistent…

Typically, when forecasting inflation rates, there are a variety of individual models and a combination of several of these models. We implement a Bayesian shrinkage combination methodology to include information that is not captured by the individual models using expert forecasts as prior…

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…

In this paper we study the effect of monetary policy shocks on commodity prices. While most of the literature has found that expansionary shocks have a positive effect on aggregate price indices, we study the effect on individual prices of a sample of four commodities. This set of commodity…

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…
