This paper tests the hypothesis that traders have rational expeatations and charge no risk premium in the forward exchange market. It uses a statistical procedure which is consistent under a large class of heteroscedasticity, and a set of data which takes into account the institutional features of the forward exchange market. The results show that inferences using this procedure are very different from those using the standard assumption of homoscedasticity.

Do traders in futures markets make use of all relevant information and is this reflected in prices? This collection of original essays by a team of international economists considers these and other questions central to futures markets.

Originally published in 1984. This book examines two important dimensions of efficiency in the foreign exchange market using econometric techniques. It responds to the macroeconomics trend to re-examining the theories of exchange rate determination following the erratic behaviour of exchange rates in the late 1970s. In particular the text looks at the relation between spot and forward exchange rates and the term structure of the forward premium, both of which require a joint test of market efficiency and the equilibrium model. Approaches used are the regression of spot rates on lagged forward rates and an explicit time series analysis of the spot and forward rates, using data from Canada, the United Kingdom, the Netherlands, Switzerland and Germany.
