This paper explores the role of capital flows and exchange rate dynamics in shaping the global economy's adjustment in a liquidity trap. Using a multi-country model with nominal rigidities, we shed light on the global adjustment since the Great Recession, a period when many advanced economies...

We construct a price index with weights for the prices of different PCE (personal consumption expenditures) goods chosen to minimize the welfare costs of nominal distortions. In this cost-of-nominal-distortions index (CONDI), the weights are computed in a multi-sector New Keynesian model with...

This paper compares the properties of interest rate rules such as simple Taylor rules and rules that respond to price-level fluctuations - called Wicksellian rules - in a basic forward-looking model. By introducing appropriate history dependence in policy, Wicksellian rules perform better than...

This paper analyzes the impact of exchange rate fluctuations when they are only partially passed through to consumer prices. We show that an exchange rate depreciation does not necessarily have a beggar-thy-neighbor effect and may in fact have an opposite, or beggar-thyself, effect. The...

The paper studies the differential impact of exchange rate fluctuations on households in a country. I extend earlier research by relaxing the assumption of complete international sectoral specialization. My setup allows for the presence of several different sectors in a given country, each...

This paper evaluates the consequences of the integration of international asset markets when goods markets are characterized by price rigidities. Using an open economy general equilibrium model with volatility in the money markets, we show that such an integration is not universally beneficial....

A growing body of research emphasizes the direct impact of exchange rate movements on the value of U.S. foreign assets. Because a substantial amount of U.S. assets are denominated in foreign currencies, a depreciation of the dollar leads to large capital gains. First, we present a detailed...

The paper explores the optimal monetary policy reaction to productivity shocks in an open economy. Whereas earlier studies assume that countries specialize in producing particular goods, I enrich the analysis by allowing for incomplete specialization. I confirm the finding of Obstfeld and Rogoff...

The U.S. dollar plays a key role in international trade invoicing along two complementary dimensions. First, most U.S. exports and imports are invoiced in dollars; second, trade flows that do not involve the United States are often invoiced in dollars, a fact that has received relatively little...

This paper provides an introduction to the recent literature on macroeconomic stabilization in closed and open economies. We present a stylized theoretical framework, illustrating its main properties with the help of an intuitive graphical apparatus. Among the issues we discuss are optimal...
