Working Papers on Economics

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…

In a previous paper (Parra-Polania and Vargas, 2015) we modify the financial constraint of a very standard model to incorporate the fact that international lenders take into account that taxes (or subsidies) affect borrowers’ income available for debt repayments, and find that ex-post…

In this paper we present estimates for the coefficients of a production function, and the corresponding total factor productivity (TFP) for the Colombian manufacturing industry during 2005{2013. We follow several structural microeconometric techniques to estimate the production function…

This paper evaluates the role of rural infrastructure on the performance of some agricultural crops in Colombia. The study utilizes geo-referenced cross sectional data of four crops, coffee, rice, beans and plantains, collected for the majority of municipalities. Using genetic matching models,…

Central banks in emerging countries frequently build-up (diminish) reserves while attempting to depreciate (appreciate) their domestic currencies. Even if these interventions are effective, they often entail various costs. Basu (2012), nonetheless, proposes a model in which the sole announcement…

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…

This paper builds a general equilibrium model that incorporates banks, financial frictions, default and a capital requirements. Ex-ante heterogeneous households decide how much to save or borrow for the sake of consumption (consumer credit) or the provision of housing services(mortgages). These…

This paper studies the effects of an in utero program on birth outcomes addressed to vulnerable pregnant women. We use information from the Buen Comienzo program, an initiative run by the local government of Medellin, the second largest city of Colombia. In order to identify the effects we…

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…

The balance sheet is a snapshot that portraits the financial position of a firm at a specific point of time. Under the reasonable assumption that the financial position of a firm is unique and representative, we use a basic artificial neural network pattern recognition method on Colombian banks…

Abstract: We investigate the effectiveness of foreign exchange interventions using the Colombian experience as a case study. Recent theoretical work emphasizes the importance of financial sector balance sheets and capital flows in determining the effects of currency…

This Appendix provides a more detailed discussion of the technical results, including proofs of theorems reported in the main paper. For ease of reference notation and definitions are repeated from the main paper.

The world economy has recently been hit by commodity price fluctuations, with first round effects on noncore inflation and second round effects on core inflation. The policy response to commodity price fluctuations depends on the first and second round effects as well as on the strength of the…

We evaluate the impacts of attending a public university in Colombia on the academic achievement of graduates from higher education. Our measurement of academic achievement represents the progress made between the college entrance and graduation standardized test scores. We find that public…

This paper is aimed to identify the main determinants of the structural unemployment rate (SUR) in Colombia. To this end, we initially look up theoretical determinants of structural unemployment as defined by a basic search and matching model. Then, we estimate different measures of the SUR…

We estimate a model of real exchange rate determination which is based on interest rate, term structure and purchasing power parities. This model takes into account sovereign risk as a key determinant with possibly non-linear effects. Estimations are performed for five Latin-American economies:…

Fluctuations in commodity prices are an important driver of business cycles in small emerging market economies (EMEs). We document how these fluctuations correlate strongly with the business cycle in EMEs. We then embed a commodity sector into a multi-country EMEs business cycle model where…
