Uncovered interest parity, monetary policy and time-varying risk premia

In a recent paper, McCallum argued that monetary-policy behavior can be responsible for the apparent empirical failure of uncovered interest parity (UIP). The present paper investigates whether optimizing policy behavior can account for the observed regime-dependence of UIP evidence. The main result is that the tradeoff between interest-rate and exchange-rate stability is a potential candidate for the explanation of the apparent failure of UIP and that the consideration of policy reactions can explain why deviations from UIP differ systematically by the exchange-rate regime.
