This paper develops a general framework to analyze the welfare consequences of monetary and fiscal shocks in an open economy, focusing on the role of the degree of substitutability between goods produced in different countries. We find that an expansionary shock that would be beneficial in a...

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...

Loose financial conditions forecast high output growth and low output volatility up to six quarters into the future, generating time-varying downside risk to the output gap, which we measure by GDP-at-Risk (GaR). This finding is robust across countries, conditioning variables, and time periods....

This paper explores financial stability policies for the shadow banking system. I tie policy options to economic mechanisms for shadow banking that have been documented in the literature. I then illustrate the role of shadow bank policies using three examples: agency mortgage real estate...

We reconsider the role of financial intermediaries in monetary economics. We explore the hypothesis that financial intermediaries drive the business cycle by way of their role in determining the price of risk. In this framework, balance sheet quantities emerge as a key indicator of risk appetite...

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....

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...
