We explore the role of interest rate policy in the exchange rate determination process. Specifically, we derive exchange rate equations from interest rate rules that are theoretically optimal under a few alternative settings. The exchange rate equation depends on its underlying interest rate...

Using exchange rate data on five currencies vis-à-vis the US dollar, this paper examines the in-sample and out-of-sample performance of exchange rate equations derived from alternative empirical and optimal interest rate rules. These rules could have either homogeneous or heterogeneous response...
