We provide a liquidity-based theory for the dominant use of the US dollar as the unit of denomination in global debt contracts. Firms need to trade their revenue streams for the assets required to extinguish their debt obligations. When asset markets are illiquid, as modeled via endogenous...

We study sovereign external debt crises over the past 200 years, with a focus on creditor losses, or "haircuts". Our sample covers 327 sovereign debt restructurings with external private creditors over 205 default spells since 1815. Creditor losses vary widely (from none to 100%), but the...

We construct a two-country New Keynesian model in which US government debt has an advantage as a superior collateral asset in the balance sheets of banks. The model can account for the observed response of the US dollar and US bond returns to a global downturn, in particular when the downturn is...

We use unique firm-level data from Mexico to document that non-financial corporations engage in carry trades by borrowing in foreign currency (FX) and lending in domestic currency, largely in the form of trade credit, accumulating currency risk in the process. We show at a quarterly frequency...

When available financial securities allow investors to optimally diversify risk across countries, standard theory implies that exchange rates should reflect this behavior. However, exchange rates observed in the data deviate from these predictions. In this paper, we develop a framework to value...

Global liquidity refers to the volumes of financial flows - largely intermediated through global banks and non-bank financial institutions - that can move at relatively high frequencies across borders. The amplitude of responses to global conditions like risk sentiment, discussed in the context...

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...

Recent theories of exchange rate determination have emphasized limited UIP arbitrage by international financial institutions. New regulations since 2008 have also lead to imperfect CIP arbitrage. We show that under limited CIP arbitrage the exchange rate and CIP deviation are jointly determined...

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'...

This paper shows that China has launched a new global system for cross-border rescue lending to countries in debt distress. We build the first comprehensive dataset on China's overseas bailouts between 2000 and 2021 and provide new insights into China's growing role in the global financial...
