Working Papers on Economics

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…

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 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,…

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…

This paper tests the importance of the financial structure of banks in the bank lending channel of monetary policy transmission in Colombia, using an unbalanced panel of 51 banks for the period of 1996:4-2014:8. We find that an increase in the interbank rate (proxy of the intervention rate) has…

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…

In this paper output gaps that include financial cycle information are evaluated against models used in policy analysis by the Colombian central bank. Employing this dataset is no trivial matter, since policy related models are the only relevant yardstick, and emerging economies (such as…

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.

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…

This paper analyzes the role of the Great Depression and protectionism in the Colombian industrialization of the early 1930s as well as the role of other determinants in the rapid industrialization that took place during the period 1934-1953. We conclude that the market pushed industrialization…

Many central banks that have opted for monetary autonomy have also been reluctant to relinquish control over the value of their currencies. As a result, they have operated through both interest rate and foreign exchange interventions.  However, in the context of the monetary trilemma, both…

We present a stochastic frontier model with random inefficiency parameters which is able to capture the influence of risk-taking on bank efficiency and that distingues those effects among banks with different characteristics. Cost and profit efficiency are found to be over- and underestimated…

We use experimental data of a training program in 2005 in Colombia. We find that even up to ten years ahead, the JeA program had a positive and significant effect on the probability to work in the formal sector, and to work for a large firm. Applicants in the treatment group also contributed…

The paper presents a global model for analysis and projections. The model features a handful of elements that make it suitable for analyzing three broad sets of topics; first, systemic risk and its transmission to country risk premiums; second, the transmission from country risk premiums to…

This paper has as main objective to build a composite metric of financial soundness for the private corporate sector in Colombia. Instead of relying on the individual and sometimes restrictive financial ratio analysis approach, the purpose of this document is to provide a single metric aimed at…

This document explores an alternative strategic asset allocation framework for foreign exchange reserves, whose main purpose is to maximize the risk-adjusted returns maintaining the objectives of liquidity and safety of a foreign reserves’ portfolio.   The overall portfolio can be…
