Abstract

Este documento combina estimaciones de 8 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 vectoriales autorregresivos que incluyen las diferentes brechas y la inflación, se construyen las densidades combinadas de pronósticos de la brecha mediante el uso de 3 esquemas de ponderación: logarítmicos, basados en puntuaciones de rango de probabilidad continuo y en el error cuadrático medio; estas densidades de la brecha resultan útiles porque proveen indicios de su tendencia central a la vez que caracterizan su incertidumbre. Los resultados sugieren que las densidades combinadas bajo estos 3 esquemas con horizontes de pronóstico de 1, 2, 3 y 4 trimestres adelante están bien especificadas. Adicionalmente, las puntuaciones logarítmicas calculadas sobre estas densidades muestran que las metodologías basadas en ponderadores logarítmicos son las que presentan mejor desempeno, y para horizontes de pronóstico de 2 y 3 trimestres, tienen significativamente una mayor puntuación que las calculadas por los ponderadores basados en puntuaciones de rango de probabilidad continuo y error cuadrático medio.
