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 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...

We develop and test a model of the global trade network. This model connects international comovements of quantities and asset prices to a simple measure of network closeness, constructed from observed trade weights. We report three findings: (1) Countries that are closer in the network tend to...

China's rising presence in international finance, which has long lagged behind its prominence in international trade, is now reshaping global financial dynamics. Using a large sample of developing countries, this paper documents that countries more reliant on China's lending are less exposed to...

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...

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