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...

For several decades until the Global Financial Crisis (GFC), Covered Interest Parity (CIP) appeared to hold quite closely--even as a broad macroeconomic relationship applying to daily or weekly data. Not only have CIP deviations significantly increased since the GFC, but potential macrofinancial...

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 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...

We consider a world capital market in which the investor population is heterogenous. Investors of different countries differ in the prices of goods at which they consume the income from their investments. In such a setting, the international CAPM incorporates rewards for exchange rate risk, in...

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...

Financial markets play two roles with implications for the exchange rate: they accommodate risk sharing and act as a source of shocks. In prevailing theories, these roles are seen as mutually exclusive and individually face challenges in explaining exchange rate dynamics. However, we demonstrate...

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...
