In an intertemporal model the impact of exchange rate risk on an international firm is studied under the assumption that no forward markets are existing in the foreign currency. However, there is a forward traded financial asset, whose spot price is highly correlated with the random spot exchange ra

Abstract
We construct models which enable a decision maker to analyse the implications of typical time series patterns of daily exchange rates for currency risk management. Our approach is Bayesian where extensive use is made of Markov chain Monte Carlo methods. The effects of several model characteristics (unit roots, GARCH, stochastic volatility, heavyβtailed disturbance densities) are investigated in relation to the hedging strategies. Consequently, we can make a distinction between statistical relevance of model specifications and the economic consequences from a risk management point of view. We compute payoffs and utilities from several alternative hedge strategies. The results indicate that modelling timeβvarying features of exchange rate returns may lead to improved hedge behaviour within currency overlay management. Copyright Β© 2000 John Wiley & Sons, Ltd.

## Abstract This study presents an empirical analysis investigating the relationship between the futures trading activities of speculators and hedgers and the potential movements of major spot exchange rates. A set of trader position measures are employed as regression predictors, including the lev
The floating of a number of European currencies in 1992 -1993 created a new body of data on foreign exchange risk premia, or deviations from uncovered interest rate parity (UIP). In this paper, excess returns to investments in SEK, NOK, FIM, GBP, ITL and ESP against the DEM are investigated. First,
## Abstract Since the adoption of flexible exchange rates, real exchange rates have been much more volatile than they were under Bretton Woods. However, the volatilities of most other macroeconomic variables have remained approximately unchanged. This poses a puzzle for standard international busin
