The paper examines the transmission mechanism of monetary policy in an open economy with and without a binding zero bound on nominal interest rates. In particular, a foolproof way of escaping from a liquidity trap is suggested, consisting of a price-level target path, a devaluation of the currency and a temporary exchange rate peg, which is later abandoned in favor of price-level or in‡ation ta...

Pro®ts appear economically and statistically signi®cant, whether risk premia are modeled as time-constant or as appreciationÕs market beta depending on Fed intervention. The estimates are sensitive to the method o...
