Se busca una raíz unitaria: evidencia para Chile

  • Rómulo Chumacero Escudero

Abstract

Este documento presenta evidencia contundente en contra de la hipótesis nula de que series tales como el IMACEC, el consumo o el PIB chilenos presentan una raíz unitaria. Esta evidencia se apoya en resultados derivados en Chumacero (2000) que muestran que en caso que alguna de estas variables de escala sea estacionaria en diferencia, los retornos de activos disponibles para los agentes deben presentar un comportamiento que se encuentra reñido con el observado en Chile. Por ello, debe tenerse gran cautela en no utilizar modelos econométricos en los que se impongan raíces unitarias sobre la base de tests tradicionales.
