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...

Recent data show substantial increases in the size of gross external asset and liability positions. The implications of these developments for optimal conduct of monetary policy are analyzed in a standard open economy model which is augmented to allow for endogenous portfolio choice. The model...

This paper develops a model of endogenous exchange rate pass-through within an open economy macroeconomic framework, where both passthrough and the exchange rate are simultaneously determined, and interact with one another. Pass-through is endogenous because firms choose the currency in which...

This paper investigates the impact of market structure on the joint determination of exchange rate pass-through and currency of invoicing in international trade. A novel feature of the study is the focus on market share of firms on both sides of the market - that is, exporting firms and...

Countries that specialize in commodity exports often exhibit a correlation between the relevant commodity price and the value of their currency. We explore a natural but little-studied explanation for this correlation. An increase in the commodity price leads to increases in the future values of...

A well-known feature of one-good, multi-agent, Arrow-Debreu economies with identical additively-separable, homothetic preferences is that the consumptions of all agents are perfectly correlated. Such economies are widely used in interpreting business cycles but seem to be inconsistent with...

International risk-sharing which diversifies away income risk will reduced saving, with constant relative risk aversion. It growth arises from the external effects of human capital accumulation then reducing saving will reduced growth. Welfare also may fall with risk-sharing, because endogenous...
