It is commonly found in empirical studies that nominal interest rates contain a unit root, implying that these variables have a permanent memory. One of the characteristics of a nonstationary time series is that it has no tendency to return to its mean values, meaning that the series is trending...

This paper reassesses the long-run relation between nominal interest rates and inflation using German data. It shows that the empirical rejection of the strict Fisher effect in previous studies, i.e., the finding of interest rates not fully adjusting to changes in inflation, can be attributed to...

The EMS crisis of 1992-1993, which resulted in the widening of the exchange rate bands, may have had some impact on the long-run structure of the system consisting of daily 1-month-Eurorates on German Mark, US-Dollar and French Franc. First, we find that both the US Eurorate and the...

This paper attempts to analyze the impact of German unification on the position that Germany holds within the European Monetary System (EMS), i.\ e.\ on the asymmetry in the EMS. Applying kernel estimation and bootstrap methods we can corroborate the result of previous studies that Germany's...

The effect of model and parameter misspecification on the effectiveness of Gaussian hedging strategies for derivative financial instruments is analyzed, showing that Gaussian hedges in the `natural'' hedging instruments are particularly robust. This is true for all models that imply...
