EL FILTRO BAXTER - KING, METODOLOGÍA Y APLICACIONES
Keywords:
Baxter-King, ciclos económicos, tendencia, Hodrick-Prescott, series.Abstract
La presente nota tiene como objetivo exponer de manera breve la metodología del filtro Baxter-King como herramienta útil para el análisis de ciclos económicos y de extracción de tendencia. También se repasan las propiedades matemáticas del filtro Hodrick-Prescott, para comprender en qué aspectos difiere del Baxter-King. Como aplicación del filtro, se analizan series con periodicidad mensual (IMAE, IPPI, Base Monetaria) trimestral (PIB) y anual (PIB e Importaciones) y se concluye que a pesar de que no difieren mucho sus resultados, el segundo es superior al Hodrick-Prescott por cuanto permite que el investigador determine el tipo de información que desea aislar de las series.
