We introduce safe asset demand for dollar-denominated bonds into a tractable incomplete-market model of exchange rates. The convenience yield on dollar bonds enters as a stochastic wedge in the Euler equations for exchange rate determination. This wedge reduces the pass-through from marginal...

As a result of the BoJ's large-scale asset purchases, the consolidated Japanese government borrows mostly at the floating rate from households and invests in longer-duration risky assets to earn an extra 3% of GDP. We quantify the impact of Japan's low-rate policies on its government and...

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 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...

I develop a general characterization of the effect that market incompleteness has on exchange rate dynamics. On the one hand, it weakens the pass-through from a country's marginal utility shocks to its own exchange rate movements; on the other hand, it gives rise to additional variations in...

We characterize the relation between exchange rates and their macroeconomic fundamentals without committing to a specific model of preferences, endowment or menu of traded assets. When investors can trade home and foreign currency risk-free bonds, the exchange rate appreciates in states that are...

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...
