Exchange Rate Volatility: Asymmetric Effects

Abstract

This paper studies the evolution of the daily exchange rates volatilities of five european currencies against the US dollar. The aim of this paper is to perform whether there are common factors in the evolution of these exchange rates flexibles during stability and unstability periods. Several alternative models have been proposed in the literature o to the model time varying volatilities. In this paper, we fit two parametric models, GARCH and GJR-GARCH for the years 1992 to 1993 and 1995 to 1997. We will show how these models within-sample estimates of volatility can be captured asymetric effects of news, specially in periods with high speculation. Summarizing, we can conclude that these results have the atractive over the exchange rate flexible markets, particularly in the risk premium exchange rate manage.
