This paper shows that properly designed interest rate rules can be consistent withmaintaining exchange rate stability. It sheds light on the relation between interest rate rules,exchange rate regimes, and determinacy of the rational expectation equilibrium in a modernmacroeconomic framework.[...]

This paper studies international trade and macroeconomic dynamics triggered by economic sanctions, and the associated welfare losses, in a calibrated, three-country model of the world economy. We assume that there are two production sectors in each country, and the sanctioned country has a...

We study a novel policy tool-interest rate uncertainty-that can be used to discourage inefficient capital inflows and to adjust the composition of external account between shortterm securities and foreign direct investment (FDI). We identify the trade-offs faced in navigating between external...

What inflation rate should the central bank target? The authors address determinacy issues related to this question in a two-sector model in which prices can differ in equilibrium. They assume that the degree of nominal price stickiness can vary across sectors and that labor is immobile. This...
