While substantial empirical research has evaluated the question of whether capital account openness promotes economic growth, this paper finds empirical evidence for cases where the opposite is true--that a policy of capital controls can promote economic growth, when combined with a policy of...

This paper develops a framework to study the management of international reserves when a government faces the risk of a rollover crisis. In the model, it is optimal for the government to reduce its vulnerability by initially lowering debt, and then increasing both debt and reserves as it...

We use a portfolio-based framework to understand what drives the decline of the U.S. net foreign asset (NFA) position and the reversal in returns earned on the US NFA (exorbitant privilege). We show that global savings gluts and monetary policies widened the U.S. NFA position, while investor...

Many central banks whose exchange rate regimes are classified as flexible are reluctant to let the exchange rate fluctuate. This phenomenon is known as "fear of floating". We present a simple theory in which fear of floating emerges as an optimal policy outcome. The key feature of the model is...

Are unregulated capital flows excessive during a stagflation episode? We argue that they likely are, owing to a macroeconomic externality operating through the economy's supply side. Inflows raise domestic wages through a wealth effect on labor supply and cause unwelcome upward pressure on...

Recent trends suggest the world economy may be tending towards an equilibrium with two distinct trading blocs, each internally integrated, but with significant isolation between the blocs. This paper uses a quantitative theory to explore how far this bifurcation would need to go to pose a threat...

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...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...

Existing high-frequency monetary policy shocks explain surprisingly little variation in stock prices and exchange rates around FOMC announcements. Further, both of these asset classes display heightened volatility relative to non-announcement times. We use a heteroskedasticity-based procedure to...

Do periods of persistently loose monetary policy increase financial fragility and the likelihood of a financial crisis? This is a central question for policymakers, yet the literature does not provide systematic empirical evidence about this link at the aggregate level. In this paper we fill...
