Fiscal Policy,Expectations, and Exchange-Rate Dynamics*
Authors:Jay H Levin
Abstract:This paper uses the sticky-price monetary model to analyze the effects of fiscal policy on the exchange rate under alternative assumptions about exchange-rate expectations. the use of different expectations mechanisms-specifically the perfect-foresight model and the popular models tested by Frankel and Froot: regressive, adaptive, and distributed-lag-is based on recent empirical evidence suggesting that exchange-rate expectations may not be rational. the most surprising finding in the paper is that with adaptive and distributed-lag expectations, fiscal expansion has no initial impact on the exchange rate, and the same may be true for regressive expectations.
