Euro and FIBOR interest rates: A continuous time modelling analysis

The introduction of the Euro in January 1999 and the new reference interest rate EURIBOR® which is widely used as the underlying interest rate for Euro denominated derivative contracts have opened up a new area of research in international financial markets. In this paper we estimate single factor models using daily EURIBOR® and FIBOR interest rate data. We also estimate a model allowing a level-GARCH specification and a two factor model. We find evidence of level-volatility effects in both rates.
