Abstract

Este trabalho avalia a eficiência preditiva dos modelos de curva de Phillips com e sem modelagem ARMA dos seus resíduos, considerando uma amostra que contêm países desenvolvidos e em desenvolvimento. O objetivo principal deste estudo é fornecer evidências empíricas de que essa simples reformulação da Curva de Phillips pode servir de benchmark para estudos que propõem modelos econométricos ou de séries temporais mais elaborados para prever a taxa de inflação. Os resultados mostram que o uso de componentes ARMA nos resíduos da Curva de Phillips diminuem consideravelmente seus erros quadrados médios de previsão para todos os países da amostra.
