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 TFP processes for the U.S. and the ""rest of the world,"" is characterized by a vector error...

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...

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...

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 TFP processes for the U.S. and the rest of the world, is characterized by a vector error correction...

We study the link between financial conditions and uncertainty in emerging markets using a Bayesian Threshold-VAR with stochastic volatility. In the model, uncertainty is measured as the time-varying volatility of the shocks. The macroeconomic effects of uncertainty shocks are contingent on...

This paper evaluates under which conditions different Taylor-type rules lead to determinacy and expectational stability (E-stability) of rational expectations equilibrium in a simple New Keynesian small open economy model, developed by Gali and Monacelli (2005). In particular, we extend the...
