Abstract

"Teniendo en cuenta que la formulación de pronósticos de la actividad económica real es sensible al tipo de variables incluidas así como a la metodología utilizada para realizar dicho pronóstico, este documento utiliza la técnica de pronósticos combinados propuesta por Stock y Watson (2004) para formular un único pronóstico del PIB colombiano. La técnica combina estimaciones construidas con diversas variables y metodologías. De tal forma, se construyen 32 indicadores líderes del PIB utilizando series mensuales que abarcan el periodo entre enero de 1995 y junio de 2008. Posteriormente, las diversas estimaciones se combinan utilizando ponderaciones que castigan el error de pronóstico histórico de cada uno de los modelos. Los resultados indican que esta metodología genera pronósticos atinados de la actividad económica ya que integra la información incluida en los distintos modelos usados para elaborar los pronósticos individuales." Abstract: "Given that forecast formulation of real economic activity is sensitive to the type of model used as well as to what variables are utilized; this document employs Stock and Watson’s (2004) methodology to generate a unique forecast for Colombian economic growth. This technique combines forecasts that have been constructed with different methodologies and variables. In this way, 32 different leading indicators were estimating using monthly series that cover the period between January 1995 and June 2008. All forecasts were combined using weights that punished the historical forecast error for each estimation. Results show that this methodology results in accurate forecasts, given that it integrates all the information embedded in the different indicators."
