We link the sustained appreciation of the U.S. dollar from 2011 to 2019 to international capital flows driven by primitive economic factors. We show that increases in foreign investors' net savings, increases in U.S. monetary policy rates relative to the rest of the world, and shifts in investor...

We show that exchange rate correlations tend to be explained by the global trade network while consumption correlations tend to be explained by productivity correlations. Sharing common trade linkages with other countries increases exchange rate correlations beyond bilateral linkages. We explain...

We analyze the role of international trade and health coordination in times of a pandemic by building a two-economy, two-good trade model integrated into a micro-founded SIR model of infection dynamics. Uncoordinated governments with national mandates can adopt (i) containment policies to...

Governments tend to increase their borrowing at the same time, giving rise to a global fiscal cycle. This global fiscal cycle has a large component that is unexplained by global business cycle variables. We propose a novel explanation for the emergence of the global fiscal cycle: governments'...

We analyze international trade and health policy coordination during a pandemic by developing a two-economy, two-sector trade model integrated into a micro-founded SIR model of infection dynamics. Disease transmission intensity can differ by goods (manufactured versus services and domestic...

We develop a portfolio-based framework to understand the deterioration of the U.S. net foreign asset (NFA) position and the returns earned on U.S. NFA (exorbitant privilege). We show global savings gluts and monetary policies widened the U.S. NFA position, while investor demand shifts offset...
