Working Papers on Economics

In this paper, we compute standard measures of fluidity for the Colombian urban labor market: worker and job reallocation rates and the excess of worker reallocation over job reallocation. We analyze the period between the second semester of 2008 and the second semester of 2014, finding evidence…

Value at Risk (VaR) is a market risk measure widely used by risk managers and market regulatory authorities. There is a variety of methodologies proposed in the literature for the estimation of VaR. However, few of them get to say something about its distribution or its confidence intervals.…

This paper analyzes efficiency in an economy with an informal sector that consists of unregulated self-employment, and where there are no costs of being informal, (Albrecht et al. (2009)). First, assuming workers in the formal sector are ex-ante heterogeneous, I show that this type of economy is…

Determining the exchange rate pass-through on inflation is a necessity for central banks as well as for firms and households. This is an apparently easy and intuitive task, but it faces high complexity and uncertainty. This paper examines the nature of the pass-through and quantifies…

This paper proposes an empirical model to identify and forecast banking fragility episodes using information on the credit funding sources. We predict the probability of occurrence of such episodes 0, 3 and 6 months ahead employing a Bayesian Model Averaging of logistic regressions. The…

The purpose of this paper is to estimate a model for gross capital flows for a sample of developing economies and assess their long-term determinants by using a panel co-integration approach. Results indicate that there is a co-integration relationship between key push and pull factors and gross…

Using the Colombian Annual Manufacturing Survey (EAM) between 2000 and 2013, this paper investigates the existence of heterogeneity in the labor demand within the industrial sector. Long run own-price, output and TFP elasticities vary across a variety of dimensions such as regions, sectors and…

In this paper we analyze the effects of financial constraints on the exchange rate through the portfolio balance channel. Our contribution is twofold: First, we construct a tractable two-period general equilibrium model in which financial constraints inhibit capital flows. Hence, departures from…

The effect of the Global Financial Crisis (GFC) has been substantial across markets and countries worldwide. We examine how the GFC has changed the way equity markets group together based on the similarity of stock indices’ daily returns. Our examination is based on agglomerative clustering…

In this paper we study exchange rate effects due to shifts in the portfolio composition of the Colombian financial sector during 2003-2014. We first provide a theoretical understanding of the channel's transmission mechanism by modeling how the banking sector optimally allocates its portfolio…

We study the existence and international migration of housing market bubbles, using quarterly information of twenty OECD countries for the period comprised between 1970 and 2015. We find that housing bubbles are present in all the countries included in our sample. Multiple bubbles are found in…

We extend the framework of Diebold and Yilmaz [2009] and Diebold and Yilmaz [2012] and construct volatility spillover indexes using a DCC-GARCH framework to model the multivariate relationships of volatility among assets. We compute spillover indexes directly from the series of asset…

In this paper we explore one of the oldest labour market phenomena documented in the literature: the added worker effect, which refers to the labour supply response of secondary workers to main earners´ job losses. To do so we take advantage of the panel data survey conducted by a Colombian…

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…

Exploiting spatial and temporal variations in the number of seizures from criminal organizations, I estimate regional fixed effects models of the increase in the number of properties confiscated on the main crime rates. From 2002 security strategies changed, and as a result,…

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 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…
