This paper analyzes how terms of trade affect aggregate productivity using a two-country monopolistic competitive business cycle model driven by aggregate technology shocks. The inefficiency of the equilibrium implies that each country’s productivity is affected by the terms of trade. This...

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...

One of the key elements for inflation targeting regime is the right identification of inflationary or disinflationary pressures through the output gap. In this paper we provide an estimation of the Peruvian output gap using a multivariate unobserved component (MUC) model, relying on an explicit...
