To study the transmission of US shocks to emerging markets, we develop and estimate an asymmetric two-country real business cycle model. The asymmetries in the model arise due to the differences in the size and the riskiness of the economies, as well as the financial frictions in the emerging...

Experiences of high-inflation economies suggest that exchange rate-based (ERB) and money-based (MB) disinflations induce sharply different dynamics in consumption and GDP. I study the role of nominal rigidities to explain such dynamics. I build on Calvo pricing to introduce elements of...

An emerging consensus on the future of macroeconomics views the incorporation of a role for financial intermediation, labor market frictions, and household heterogeneity in the presence of uninsurable unemployment risk as key needed extensions to the benchmark macro framework. I argue that this...

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...

International financial integration has greatly increased the scope for changes in a country's net foreign asset position through the valuation channel of external adjustment, namely capital gains and losses on the country's external assets and liabilities. We examine this valuation channel...
