Abstract

En este trabajo se realiza un análisis empírico sobre la cotización del dólar durante el periodo 2000-2016, el objetivo es seleccionar un modelo estadístico que caracterice con precisión los impactos de la variación del precio en la economía mexicana. Se aplica la metodología de series de tiempo para estudiar la volatilidad de la divisa y se comparan los resultados de las estimaciones que arroja el modelo ARCH (Engle, 1982) y GARCH (Bollerslev, 1986. Se concluye que el modelo GARCH representa con mayor precisión los cambios en la volatilidad de la paridad cambiaria y los resultados validan la hipótesis de alta volatilidad originada por factores ajenos al desempeño de la economía mexicana. Se identifica como futura línea de investigación para ampliar el trabajo de un análisis comparativo entre los modelos GARCH, EGARCH y PARCH./In this paper, an empirical analysis is performed on the dollar's price during the period 2000-2016, the objective is to select a statistical model that accurately characterizes the impacts of the price variation in the Mexican economy. The time series methodology is applied to study the volatility of the currency and the results of the ARCH model (Engle, 1982) and GARCH (Bollerslev, 1986) are compared. It is concluded that the GARCH model represents more accurately the changes in exchange rate volatility and the results validate the hypothesis of high volatility caused by factors beyond the performance of the Mexican economy. A comparative analysis between the GARCH, EGARCH and PARCH models is identified as a future line of research to extend the work.
