The impact of an unanticipated monetary shock in a small open economy with dollarization, factor price rigidities, and nontradeables is re-examined in an optimizing intertemporal general equilibrium model. The framework of an earlier study is extended to incorporate foreign real money balances...

We analyse nominal exchange rate and price dynamics after risk premium shocks with short-term interest rates constrained by the zero lower bound (ZLB). In a small-open-economy DSGE model, temporary risk premium shocks lead to shifts of the exchange rate and the price level if a central bank...

In this paper we calculate robustly optimal monetary policy rules for several variants of a simple optimizing model of the monetary transmission mechanism with sticky prices and/or wages. We discuss representations of optimal policy both in terms of interest-rate feedback rules that generalize...
