Can macroprudential foreign exchange (FX) regulations on banks reduce the financial and macroeconomic vulnerabilities created by borrowing in foreign currency? To evaluate the effectiveness and unintended consequences of macroprudential FX regulations, we develop a parsimonious model of bank and...

Recent evidence on the importance of cross-border equity flows calls for a rethinking of the standard theory of external adjustment. We introduce equity holdings and portfolio choice into an otherwise conventional open-economy dynamic equilibrium model. Our model is simple and admits a...

We show that the when one takes into account the global equilibrium ramifications of an unwinding of the US current account deficit, currently estimated at 5.4% of GDP, the potential collapse of the dollar becomes considerably larger--more than 50% larger--than our previous estimates (Obstfeld...

This paper studies how several macrofinancial factors are associated over time with the evolution of covered interest parity (CIP) deviations in the decade after the Global Financial Crisis. Changes in a number of risk- and policy-related factors have a significant association with the evolution...

In a previous paper, "Trade in Risky Assets," I have analyzed the pattern of international trade in risky real assets between barter economies, relying on the Law of Comparative Advantage and using autarky asset price differences to predict the pattern of asset trade. In this paper the analysis...

This paper discusses the profound difficulties of maintaining fixed exchange rates in a world of expanding global capital markets. Contrary to popular wisdom, industrialized-country monetary authorities easily have the resources to defend exchange parities against virtually any private...

The U.S. dollar’s nominal effective exchange rate closely tracks global financial conditions, which themselves show a cyclical pattern. Over that cycle, world asset prices, leverage, and capital flows move in concert with global growth, especially influencing the fortunes of emerging and...

This paper incorporates international capital flows into a two-country, monetary-general-equilibrium model of asset prices with investment and production. We use the model to calculate theoretical covariances between investment, the current account, the exchange rate, and the terms of...

This paper examines the impact of globalization on the cost of equity capital. We argue that the cost of equity capital decreases because of globalization for two important reasons. First, the expected return that investors require to invest in equity to compensate them for the risk they bear...

We provide a simple and intuitive measure of interdependence of asset returns and/or volatilities. In particular, we formulate and examine precise and separate measures of return spillovers and volatility spillovers. Our framework facilitates study of both non-crisis and crisis episodes,...
