Este trabajo pretende determinar qué conjunto de rigideces nominales y reales se debe incluir en un modelo DSGE para replicar la dinámica de las variables agregadas de la economía colombiana. Con este fin, se estiman varios modelos DSGE con distintas combinaciones de rigideces nominales y...

En este artículo se propone un método numérico para la calibración de un modelode equilibrio general dinámico y estocástico (DSGE). Esencialmente, éste consisteen utilizar un algoritmo híbrido de optimización, primero para encontrar un estadoestacionario del modelo, y luego para...

La evidencia empírica para Colombia muestra relaciones tanto positivas como negativas entre el crecimiento del producto y empleo, a diferencia de lo encontrado en economías desarrolladas como la de los Estados Unidos. El presente trabajo usa modelos VAR y de Equilibrio General Dinámico y...

In this paper two new measures of the Colombian output gap and the real neutral interest rate are proposed. Instead of relying only on statistical filters, the proposed measures use semi-structural New-Keynesian models, adapted for a small open economy. The output gap measures presented are in...

In this document we lay out the microeconomic foundations of a dynamic stochastic general equilibrium model designed to forecast and to advice monetary policy authorities in Colombia. The model is called Policy Analysis Tool Applied to Colombian Needs (PATACON). In companion documents we present...

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...

If theory-consistent models can ever hope to forecast well and to be useful for policy, theyhave to relate to data which though rich in information is uncertain, unbalanced and sometimes forecastsfrom external sources about the future path of other variables. One example from many is financial...

El gobierno es un agente que influye sobre la actividad económica a lo largo del ciclo y afecta las variables reales y nominales de un país por medio de sus políticas de ingreso y de gasto. También es un determinante importante de la estabilidad macroeconómica, en cuanto que esta depende,...

The sudden collapse of oil prices poses a challenge to inflation targeting central banks in oil exporting economies. This paper illustrates that challenge and conducts a quantitative assessment of the impact of permanent changes in oil prices in a small and open economy, in which oil represents...

Evidence of smooth transition autoregressive (STAR) representations is found in two, out of three, time series of different measures of annual inflation in Colombia during this decade for monthly data. The STAR-type nonlinearities are asymmetric for inflation computed as the variation of CPI...
