New results on the rationality of survey measures of exchange-rate expectations

In light of research questioning the usefulness of economists' models of exchange-rate determination, this paper investigates the rationality of survey measures of expectations for Deutschmark/dollar exchange rates for 1989-97. Using Liu and Maddala's (1992) "restricted cointegration" test, the author cannot reject the assumption that survey measures are unbiased exchange-rate forecasts. This finding is related to market participants' anticipation of the impact of economic policies.
