The trade-off between interest rate variability and the width of an exchange rate target zone is examined, using the regulated Brownian motion model of target zones. The interest rate differential’s asymptotic (unconditional) variability is increasing in the exchange rate band for narrow...

In this paper we investigate how firms adjust markups across products in response to fluctuations in the real exchange rate. In a theoretical framework, we show that firms increase their markup and producer prices following a real depreciation and that this increase is greater for products with...
