In this article, we examine the intradaily Euro-dollar exchange rate volatility persistence result from the dissymmetric impact of monetary policy signals stemming from the ECB Council and the FOMC. A model is constructed by extending the AR(1)-GARCH (1,1) to an exponential process EGARCH (1,1),...

The regime switching models are particularly popular in the comity of non-linear models; it is of interest to investigate regime switching models with GARCH specification. GARCH model was augmented with STAR model vis-a vis Exponential autoregressive GARCH (EAR-GARCH), Exponential smooth...
