Monetary Policy and Real Exchange Rate Dynamics in Sticky-Price Models

We study how real exchange rate dynamics are affected by monetary policy in dynamic, stochastic, general equilibrium, sticky-price models. Our analytical and quantitative results show that the source of interest rate persistence – policy inertia or persistent policy shocks – is key. In the presence of persistent monetary shocks, increasing policy inertia may decrease real exchange rate persistence, hampering the ability of sticky-price models to generate persistent real exchange rate deviations from parity.
