Working Papers on Economics

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:…

In 2013 Colombia implemented a tax reform which, among other things, reduced payroll taxes by a total of 13.5 percentage points of wages. In this paper we evaluate the effects of this component of the 2012 Colombian tax reform on firms’ formal employment and average wages. We construct a panel…

Most of the literature on the effectiveness of foreign exchange intervention has yet to reach a general consensus. In part, this is due to the different estimation methods in which exogenous variation is identified. In this sense, the use of heavily-dependent parametric models can sometimes…

Fiscal multipliers are different across countries and according with economic circumstances. The studies about the effect of a government spending shock on output have focus their attention on the behavior of consumption. However, the crowding out of investment is also an important matter of…

This paper estimates the local efficiency of the public provision of education in Colombia between 2007 and 2014. The empirical analysis relies on a multiproduct function that assesses public performance considering two types of education products: quality and enrolment. Results for Colombian…

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…

Inglés: In spite of the increasing evidence that has revealed that early access to financial services has long-term impacts, children and adolescents continue to face major obstacles to be financially included, particularly in the developing world. This document presents the main results of a…

Inglés: We propose a maximal covering location problem with a budget constraint to determine the optimal location of facilities that provide fast police assistance to homicide hot spots, to mitigate criminal activity in Medellín (Colombia). We use the Google Maps Application Programming…

This work uses readily accessible data about the stocks of unemployed workers, labor force and duration of unemployment to measure the job finding and separation rates for Colombia from 1984 to 2014. It also evaluates the relative contribution of these rates to the fluctuations of unemployment…

Determinants of consumer credit are estimated by using information from a Credit Union located in Medellín-Colombia. To the best of our knowledge, this is the first investigation using this kind of data in Colombia. We find that life cycle-permanent income hypothesis (LC-PIH) related variables…

We study the interdependence between real commodity prices and world real GDP using long-term annual data since 1870, by performing two empirical exercises. First, we compute long-term and medium-term cycles and measure their degree of synchronization for different leads and lags. Second, we…

This paper assesses the efficiency of crop and livestock production in Colombia by using a sample of 1,565 households. The study considers households located in different production systems which differ in geography, climate and soil types. These conditions affect technical efficiency and thus…

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…

We introduce a dispatch model of Colombia's independent system operator (XM) in order to study the relative merits of self-commitment vs. centralized unit comment.  We capitalize on the transition that took place in 2009 from self-unit commitment to centralize unit commitment and use data…

This paper reports on the recent developments in the construction of an interregional input-output matrix for Colombia (IIOM-COL). As part of an ongoing project that aims to update an interregional CGE (ICGE) model for the country, the CEER model, a fully specified interregional input-output…

This paper provides evidence on the positive role of fiscal decentralization on regional economic growth in Colombia since the promulgation of the Political Constitution of 1991. The empirical strategy involved the choice of a suitable estimator for the panel data approach, the Augmented Mean…

R&D intensity for small firms is high and persistent over time. At the same time, small firms are often financially constrained. This paper proposes a theoretical model that explains the coexistence of these two stylized facts. It is shown that self-financed R&D investment can distort…

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.…

Inflation expectations in Colombia are characterized. Empirical evidence following conventional tests suggests that they might not be rational, although the period of disinflation included in the sample makes it difficult to ascertain this conclusion. Inflation expectations display close ties…

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…
