Working Papers on Economics

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…

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…

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…

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…

Macroprudential tools have been used around the world as a mechanism to control potential risks and imbalances in the financial sector. Colombia is a good example of a country that has employed different regulatory measures to manage systemic risks in the economy. The purpose of this paper is to…

In this study we construct volatility spillover indexes for some of the major stock market indexes in the world. We use a DCC-GARCH framework for modelling the multivariate relationships of volatility among markets. Extending the framework of Diebold and Yilmaz [2012] we compute spillover…

Abstract: An audit study was conducted in Colombia following the protocols in Giné and Mazer (2017). Trained auditors visited multiple financial institutions, seeking credit and savings products. Consistent with Gabaix and Laibson (2006) and similar to Giné and Mazer (2017), the…

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…

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…
