Abstract

Este trabajo eval�a 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 compr� divisas para compensar las reevaluaciones frente al d�a anterior y para corregir tendencias excesivas", cuando se redujo la presi�n inflacionaria y cuando el Banco Central tuvo una posici�n acreedora neta. La estimaci�n 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 d�a) como en el mediano plazo (1 mes, 3 meses y 6 meses). Las posibles contradicciones macroecon�micas no fueron suficientemente fuertes como para afectar la funci�n de reacci�n de las autoridades o el impacto de las intervenciones. El trabajo utiliza metodolog�as que permiten evaluar la estabilidad de los par�metros de la ecuaci�n de media y de volatilidad para el modelo E-GARCH en forma simult�nea."
