Modelos GARCH, volatilidad cambiaria, metas de inflación, crisis financiera globalResumen
El proposito de esta investigación es identificar el efecto asimétrico generado por impactos positivos y negativos en la volatilidad del tipo de cambio. Además de determinar el efecto generado por la implementación del regimen de Metas de Inflación (MI) y la crisis financiera global (CFG) en la varianza condicional de las principales divisas de América Latina (Brasil, Chile, Colombia, México y Perú). Se emplea un modelo asimétrico de heterocedasticidad Condicional Autorregresiva Generalizada, con innovaciones t de student (ARIMA-GJR-GARCH), aplicado sobre datos diarios de 1997 a 2019. Los principales hallazgos muestran que existe un mayor impacto de las depreciaciones cambiarias sobre la volatilidad del tipo de cambio. Además, se encontró que el esquema de MI ha incrementado la volatilidad de las divisas, principalmente en Brasil, Chile y México. Finalmente, la CFG de 2008 parece haber generado un clima de mayor volatilidad en las divisas de la región.
