Abstract

Este documento combina estimaciones de ocho metodologías de la brecha del producto colombiano para el período comprendido entre el primer trimestre de 1994 y el tercer trimestre de 2012. A partir de modelos VAR que incluyen las diferentes brechas y la inflación se construyen las densidades combinadas de pronósticos de la brecha mediante el uso de tres esquemas de ponderación: logarítmicos, basados en puntuaciones de rango de probabilidad continuo (CRPS) y basados en el error cuadrático medio (MSE). Los resultados sugieren que las densidades combinadas bajo estos tres esquemas con horizontes de pronóstico de uno, dos, tres y cuatro trimestres adelante están bien especificadas. Adicionalmente, las puntuaciones logarítmicas calculadas sobre estas densidades muestran que las metodologías basadas en ponderadores logarítmicos para horizontes de pronóstico de dos y tres trimestres tienen significativamente un mejor desempeño que las calculadas por los ponderadores CRPS y MSE.
