This paper develops a new open economy macro model of optimal monetary for a small open economy. Our main result is that in this model, the optimal policy problem for the small open economy is isomorphic to the closed economy case studied in Clarida, Gali, Gertler (1999). In particular, the...

The purpose of this paper is to explain deviations from PPP in an economy charaterived by a mononolistic competitive market structure in which pricing decisions incur costs. That lead producers to pre-set the price path for several periods. The paper derives an optimal pricing rule, including...

We develop a general mandate framework for delegating monetary policy to an instrument-independent, but goal-dependent central bank. The goal of the mandate consists of: (i) a simple quadratic a loss function that penalizes deviations from target macroeconomic variables; (ii) a form of a...

We develop a optimal rules-based interpretation of the ''three pillars macroeconomic policy framework'': a combination of a freely floating exchange rate, an explicit target for inflation, and a mechanism than ensures a stable government debt-GDP ratio around a specified long run. We show how...

Limited asset market participation (LAMP) and trade openness are crucial features that characterize all real-world economies. We study equilibrium determinacy and optimal monetary policy in a model of a small open economy with LAMP. With low enough participation in asset markets, conventional...
