    El modelo gaussiano GARCH(1,1) ha sido empleado, tradicionalmente, en el estudio de la tasa de cambio; sin embargo, un número importante de estudios recientes (utilizando modelos FIGARCH e HYGARCH) ha encontrado evidencia de persistencia en su volatilidad. En este trabajo, usando una estrategia de modelos anidados, se encontró evidencia a favor del modelo IGARCH bajo una distribución GED. Los pronósticos del modelo IGARCH son usados para calcular la estructura a plazos y la volatilidad multi-período, las cuales permiten conocer las expectativas del mercado sobre la volatilidad de los retornos, en diferentes horizontes de tiempo.
