We explore the interplay between trade invoicing patterns and the pricing of safe assets in different currencies. Our theory highlights the following points: 1) a currency's role as a unit of account for invoicing decisions is complementary to its role as a safe store of value; 2) this...

At the onset of the COVID-19 economic crisis, as in other crisis episodes, the flight to safety was accompanied by a rapid appreciation of "safe haven" currencies. We quantify currency-induced balance sheet effects for total external positions as well as for individual asset classes using new...

The use of different currencies in the invoicing of international trade transactions plays a major role in the international transmission of economic fluctuations. Existing studies argue that an exporter's invoicing choice reflects structural aspects of her industry, such as market share and the...

The U.S. dollar holds a dominant place in the invoicing of international trade, along two complementary dimensions. First, most U.S. exports and imports invoiced in dollars. Second, trade flows that do not involve the United States are also substantially invoiced in dollars, an aspect that has...

How does growing international financial diversification affect firm-level and aggregate labor shares? We study this question using a novel framework of firm labor choice in the face of aggregate risk. The theory implies a cross-section of labor risk premia and labor shares that appear as...

The rise of artificial intelligence (AI) and of cross-border restrictions on data flows has created a host of new questions and related policy dilemmas. This paper addresses two questions: How is digital service trade shaped by (1) AI algorithms and (2) by the interplay between AI algorithms and...

Recent supply disruptions catapulted the issue of risk in global supply chains (GSCs) to the top of policy agendas and created the impression that shortages would have been less severe if GSCs were either shorter and more domestic, or more diversified. But is this right? We start our answer by...

Considerable progress has been made in our understanding of the relationship between international trade and the environment since Gene Grossman and Alan Krueger published their now seminal working paper examining the potential environmental effects of the North American Free Trade Agreement in...

Artificial Intelligence is a powerful new technology that will likely have large impacts on the size, direction and composition of international trade flows. Yet almost nothing is known empirically about this. One AI-enabled set of services that can be tracked resides in the palm of our hands:...

This chapter was prepared for the Handbook of International Economics (Vol. 5) edited by Gita Gopinath, Elhanan Helpman, and Kenneth Rogoff. We provide a review of the recent literature -- both theoretical and empirical -- analyzing the multi-dimensional connections between globalization and...
