Working Papers on Economics

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…

This paper evaluates the impact of Resolution CREG 051 on the performance of the electricity markets in Colombia. We found out that productive efficiency has improved since the introduction of the Resolution, that is, the total costs of producing electricity have been reduced. This shows a…

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…

This paper analyzes the effect of social security and lump sum layoff payment in an economy with an informal sector and savings, where the search effort is unobserved. I characterize the optimal consumption/search/non-participant strategy assuming that workers are risk averse and that formal…

Many central banks, particularly in the developing world, aim for exchange rate stability as a macroeconomic goal. However, most are reluctant to relinquish monetary policy autonomy, so they end up operating through both interest rate and foreign exchange interventions. But the use of multiple…

This document explores the predictive power of the yield curves in Latin America (Colombia, Mexico, Peru and Chile) taking into account the factors set by the specifications of Nelson & Siegel and Svensson. Several forecasting methodologies are contrasted: an autoregressive model, a vector…

This paper investigates the impact of sovereign risk on the stochastic rational expectations equilibrium of a pure exchange small open economy. International borrowing and lending arise from the interaction between a risk averse sovereign representative agent in a small open economy trying to…

In this paper I explore the potential link between Plan Colombia and violence with a new perspective. I focus the analysis only on the first three running years of the program (2000-2002) in order to avoid the overlapping effect with a security policy started in 2002/2003. This paper exploits…

This paper provides empirical evidence of the impact of fiscal decentralization on Colombia's public basic education. Based on the social and economic data available for 1,003 municipalities and 13,670 public schools, for the last decade, we confirmed that decentralization has had a positive and…

We assess the effects of the Colombian Unemployment Subsidy (US) program on future labor participation, unemployment, formality, school attendance and earnings of its beneficiaries, on household earnings and school attendance of the household members, and on weight and height of their children…

In the context of financial crises influenced by the development and burst of housing price bubbles, the detection of exuberant behaviors in the financial market and the implementation of early warning diagnosis tests are of vital importance. This paper applies the new method developed by…

We use a unique data set at the individual level to estimate an empirical model explaining the probability of young individuals to become criminals as a function of the presence of adult criminals in their neighborhoods, an a complete set of control variables, including census sector fixed…

This paper investigates whether transforming the Consumer Price Index with a class of power transformations lead to an improvement of inflation forecasting accuracy. We use one of the prototypical models to forecast short run inflation which is known as the univariate time series ARIMA . This…

Banco de la República’s FX intervention policy is described, with a focus on its objectives and main features. Then, based on a survey of the effectiveness of sterilized intervention in Colombia, it is argued that this tool is not useful to cope with the challenges posed by medium term external…

In this paper we develop a dynamic stochastic general equilibrium fiscal model for the Colombian economy. The model has three main components: the existence of non-Ricardian households, price and wage rigidities, and a fiscal authority that finances government spending partly with public debt.…

The paper examines the bidders behaviour in the Colombian government bond auctions during 2007 for the period in which there is no uncertainty in the supply. Three main findings are presented. First, in contrast with other treasury auctions (Castellanos [2]), the market clearing price in the…

This paper examines inflation expectations of the World Economic Survey for ten inflation targeting countries. First, by a Self Organizing Maps methodology, we cluster the trajectory of agents inflation expectations using the beginning of the oil price shock occurred in June of 2014 as a…

The recent financial crisis has renewed the interest of economists, both at the theoretical and empirical level, in developing a better understanding of credit and its mechanisms. A rapidly growing strand of the literature views banks as facing funding restrictions that condition their borrowing…

Since correlation may be interpreted as a measure of the influence across time-series, it may be conveniently mapped into a distance and into a weighted adjacency matrix. Based on such matrix, network theory has attempted to filter out the noise in correlation matrices by extracting the dominant…

The adoption of a managed regime assumes that interventions are relatively successful. However, while some authors consider that foreign exchange interventions are ineffective, arguing that domestic and foreign assets are close substitutes, others advocate their use and maintain that their…
