Ainda os modelos GARCH

Resumo

This article summarizes the huge literature on GARCH Models. It is a survey on this subject to spread those models throughout the Portuguese readers. Issler (1999) briefly introduces univariate GARCH models, and provides results ofseveral Brazilian univariate financial series. We extend such study in terms ofspecification of the univariate model and by presenting the Multivariate GARCH Models.
