Abstract

Este trabajo evalúa los determinantes de las compras de divisas y su impacto sobre la tasa de cambio nominal en Colombia durante 2000-2008. Estimaciones Tobit muestran que el Banco Central compró divisas para compensar las reevaluaciones frente al día anterior y para corregir tendencias excesivas", cuando se redujo la presión inflacionaria y cuando el Banco Central tuvo una posición acreedora neta. La estimación de un modelo E-GARCH muestra que las compras de divisas devaluaron la tasa de cambio y redujeron su volatilidad, tanto en el corto (1 día) como en el mediano plazo (1 mes, 3 meses y 6 meses). Las posibles contradicciones macroeconómicas no fueron suficientemente fuertes como para afectar la función de reacción de las autoridades o el impacto de las intervenciones. El trabajo utiliza metodologías que permiten evaluar la estabilidad de los parámetros de la ecuación de media y de volatilidad para el modelo E-GARCH en forma simultánea."
