If calibrated to an observed term structure of interest rates that only covers a finite range of times-to-maturity an HJM-model of the term structure of interest rates will eventually die out in finite time as bonds reach maturity. This poses problems for the pricing and hedging of certain...

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...

This study uses non-stationary econometrics to analyze asymmetry and dominance within the EMS through interest rate linkages between the French franc, the German deutsche mark and the US dollar. High frequency data (daily Eurorates from April 1983 to the end of 1992) are used for their better...

Discount rate changes always receive considerable attention in financial markets and a bulk of empirical papers shows that asset prices react to them. However, among researcher, there is no consensus yet about why markets respond to such changes. This paper analyses this issue for the...

This paper collects some results of the authors on minimax estimation of parameters in linear (regression) models disturbed by some nuisance parameters. In contrast to conventional modelling, the disturbances are not specified as random variables but rather as unknown parameters, for which some...

A term structure model with lognormal type volatility structure is proposed. The Heath, Jarrow and Morton (HJM) framework, coupled with the theory of stochastic evolution equations in infinite dimensions, is used to show that the resulting rates are well defined (they do not explode) and remain...

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...

Modern neo-Keynesian, new classical, and real business cycle models typically differ in the degree to which they incorporate long-run or short-run neutrality propositions. Despite their importance, little firm international evidence on the validity of these neutrality hypotheses is available 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...
