Working Papers on Economics

The study presented here looks at the Colombian corporate sector broken down by city.  In particular, it studies the eight main cities of the country.  It is an initial study, maybe the first of its kind, and it aims to act as a foundation for future research in the area.  A…

In this paper we model the effect of migrant remittances on job creation and human capital formation, given migration prospects. Model calibration of deep parameters was performed with data from the AMCO survey on migration and remittances. The simulations based on the model show that…

In this paper we check the relationship between the yields of the Colombian bonds traded in the (secondary) internal market and the yields of the sovereign global securities for the sample period 1999-2001. The hypothesis we maintain is that, under the assumption of capital mobility, it should…

In this paper, we propose a methodology for calculating a leading index of the economic activity based on a modification of Stock and Watson’s (1989, 1991, 1992) approach. We use Kalman filter techniques for estimating the state space representation of the leading index model. The methodology is…

General equilibrium theory was criticized for its apparent irrefutability, as seemingly implied by the Sonnenschein-Mantel-Debreu theorem.  This view was challenged by Brown and Matzkin (1996), who showed the existence of testable restrictions on the equilibrium manifold. Brown and Matzkin…

This paper provides an empirical analysis of Colombian integration with East Asia using a Computable General Equilibrium (CGE) model, in which we assess the effects of several trade liberalization scenarios on trade flows and welfare.The results show that there is an important potential for the…

In this paper I consider the following problem: there is a collection of exogenously given socially feasible sets, and for each one of them, each one of a group of individuals chooses from an individually feasible set. The fact that the product of the individually feasible sets is larger than…

This paper investigates the effect of sovereign risk on the stochastic rational expectations equilibrium of a real business cycle small open economy. The market is imperfect because the sovereign cannot commit to repay its outstanding debt and chooses to default when it is optimal to do so. The…

This paper studies the dynamic response of a few key macroeconomic variables to each one of three exogenous shocks: monetary, government spending and technological shocks. By using a cash in advance model with two market frictions, one in the intermediation of loanable funds, and one in the…

In a small macroeconomic model of the Colombian economy I investigate the problem of selecting a policy rule that is consistent with inflation targeting. I spell out the characteristics of the optimal feedback and output parameters in the rule, as well as for the optimal forecasting horizon for…

This paper studies the performance, in terms of volatility and welfare, of different monetary policy rules in an economy with two market frictions. We consider a financial friction that highlights the credit channel as the monetary transmission mechanism and a labor friction, that considerably…

A pseudo-panel was built to estimate the determinants of the labor participation decision of married women between 1984 and 2000. Past participation decisions, education level, labor income taxes, children between 1 and 2 years of age, and the presence of other people unemployed at home are the…

This paper estimates an asymmetric error correction model to analyse the dynamic behaviour of the Colombian unemployment rate. We find evidence that wages above their long-run equilibrium level do increase unemployment, but wages below this level do not reduce it.

The empirical literature about economic growth has usually ignored spatial interdependence among countries. This paper uses spatial econometrics to estimate a growth model that includes cross-country interdependence, in which a country’s economic growth depends on the growth rate of its…

This paper quantifies the welfare effects of decentralisation in Colombia, using a multiregional CGE model. We investigate to what extent will the Colombian population be better off when goods such as health and education, are delivered locally as against centrally. A provision scheme based on…

In this theoretical report, the identifiability property of a coincident index model is studied.  As a result, characterization of the identifiability conditions solves a model specification problem, which was detected in the design of an earlier index for the Colombian economy.   Key…

 At a request from the Ministry of Finance, Banco de la República last year carried out an investigation into the feasibility to use parts of the foreign reserves to buy back some of Colombia’s outstanding sovereign U.S.-dollar debt.  This project resulted in two thorough technical…

Structural VAR and Structural VEC models were estimated for Chile and Colombia, aiming at identifying fiscal policy shocks in both countries between 1990 and 2005. The impulse responses obtained allow the calculation of a peso-for-peso ($/$) effect on output of a shock to public spending and to…

 In this paper we find empirical evidence of bank lending channel for Colombia and Argentina. As for Argentina, we do not find evidence that changes in the interbank interest rate affect the growth rate of total loans directly. However, it does indirectly through interactions: the interbank…
