We compute both seigniorage rate and  welfare cost of inflation rate in Colombia using a  Sidrauski-type model  in which preferences are separable functions of the service flows of  non-durable goods and  money holdings.  The set of the estimated parameters imply…

Transmission mechanisms and inflation targeting: the case of Colombia’s desinflation

This study develops three exchange rate models as well as a simple statistical model defined as a random walk with a variable drift. The exchange rate models all use the purchasing power parity hypothesis to account for the long-term relationships between prices and the exchange rate, together…

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…

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…

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…

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 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…

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…

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…

At the end of the last decade, the real activity in Colombia underwent the sharpest recession of the last fifty years. We postulate a non-triangular structural VAR model (Amisano and Giannini, 1997) to describe the dynamics of output, prices, unemployment and wages during the last two decades.…

This paper tests for purchasing power parity (PPP) between Colombia and its main trading partners using the Johansen framework of multivariate cointegration. The tests shows that PPP does not hold in the strong sense, but a clear purchasing power relationship is, nevertheless, show to exist. The…

This paper examines whether central banks in Latin America have implemented conventional inflation targeting (IT) prescriptions, with a focus on foreign exchange intervention and official reserves accumulation policies. To this end, the paper reviews the experiences of Brazil, Chile, Colombia,…

This study uses two different econometric frameworks to study exchange rate pass-through to import, producer and consumer prices in Colombia. Both frameworks are based on vector autoregressive (VAR) models, the first using an unrestricted VAR model, and the second using the Johansen framework of…
