This paper develops a framework for analyzing the effects of fiscal policy on the real exchange rate. The short-run impact of various types of fiscal measures are considered as well as the dynamics of adjustment to long-run steady states. The analysis and related simulations suggest that the effect of fiscal policy changes on the real exchange rate can vary widely and will depend closely on a number of structural features, including the degree of asset substitutability, the composition of government spending, and the initial size of the public debt and net external position.
