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...

Foreign investors' changing appetite for risk-taking have been shown to be a key determinant of the global financial cycle. Such fluctuations in risk sentiment also correlate with the dynamics of UIP premia, capital flows, and exchange rates. To understand how these risk sentiment changes...

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...

This paper investigates the implications of international financial sanctions for the reserve currency status of the US dollar. We propose a simple model of a reserve currency, demonstrate how the anticipation of financial sanctions can weaken the dollar's status, and evaluate the welfare...

We study the effects of debt-financed fiscal transfers in a general equilibrium, heterogeneous-agent model of the world economy. In the long run, increases in government debt anywhere raise the world interest rate and increase private wealth everywhere. In the short run, a country with a...

This paper studies the transmission channels of monetary and macroprudential policies in an open economy framework and evaluates the normative implications for international spillovers and global welfare. An analytical decomposition uncovers the prominent role of expenditure switching for...

I propose a dynamic model of the reserve currency paradigm that centers on the liquidity demand for safe assets. In global recessions, the demand for the U.S. safe bond increases and raises its convenience yield, giving rise to a stronger dollar and a countercyclical seigniorage revenue. The...

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...

Financial integration generates macroeconomic spillovers that may require international monetary policy coordination. We show that individual central banks may set nominal interest rates too low or too high relative to the cooperative outcome. We identify three sufficient statistics that...

We re-examine monetary policy spillovers to Emerging Market Economies (EME) in the form of capital flow reversals, using sectoral-level securities holdings data for Euro Area investors. In response to a surprise monetary tightening, active investors such as investment funds re-balance their...
