We study how determinacy and expectational stability (E-stability) of rational expectations equilibrium may be affected by monetary policy when the cost channel of monetary policy matters. We focus on both instrumental Taylor-type rules and optimal target rules. We show that standard instrument...

We evaluate the expectational stability (E-stability) of rational expectations equilibrium in a simple "New Keynesian" small open economy model. In particular, we extend Bullard and Mitra (JME, 2002) results of E-stability in closed economy to an open economy framework by evaluating Taylor-type...

A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are...

A central puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard International Real Business Cycle (IRBC) models cannot reproduce this fact when calibrated using conventional parameterizations, and can only generate one fourth of the real...

How important are nontradable goods and distribution costs to explain real exchange rate dynamics? We answer this question by estimating a general equilibrium model with intermediate and final tradable and nontradable goods. We obtain reasonable estimated parameter values using Bayesian methods,...

This paper revisits the role of terms of trade using a small open economy (SOE) model in which imports are inputs in production, output markets are imperfectly competitive and firms are connected in an input-output network. Otherwise, the model nests the standard SOE model commonly used in...
