Hegemonic powers, like the United States and China, exert influence on other countries by threatening the suspension or alteration of financial and trade relationships. Mechanisms that generate gains from integration, such as external economies of scale and specialization, also increase the...

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

International transactions are costly because they require investments in logistics, contracts, and the acquisition of local institutional knowledge. We posit that a portion of the fixed costs of entering a specific export market can be used toward costs of acquiring imports from that same...

Yes. We state closed-form expressions for steady state gains from trade that apply in a class of dynamic trade models that includes dynamic versions of the Krugman (1980), Melitz (2003), and customer capital (e.g., Arkolakis, 2010) models. The gains are a function of the domestic trade share and...

Geoeconomics is the use of a country's economic strength to exert influence on foreign entities to achieve geopolitical or economic goals. We discuss how concepts of power in the political science and economics literature can be used to guide research on geoeconomics. Economic threats as a form...

A structural gravity model is used to estimate barriers to services trade across many sectors, countries and time. Since the disaggregated output data needed to flexibly infer border barriers are often missing for services, we derive a novel methodology for projecting output data. The empirical...

We discuss biases in preferences and their trade effects in terms of impacts on non-neutral trade flows motivated by recent literature on both home bias and the border effect. These terms take on multiple definitions in the literature and are often used interchangeably even though they differ....

The gravity model has been widely used to infer substantial trade flow effects of institutions such as customs unions and exchange rate mechanisms. McCallum [1995] found that the US-Canada border led to trade between provinces that is a factor 22 (2,200%) times trade between states and...

We examine the within- and across-firm shipment decisions of tens of thousands of goods-producing and distributing establishments. This allows us to quantify the normally unobservable forces that determine firm boundaries; which transactions are mediated by ownership control, as opposed to...

We introduce a general quantifiable framework to study the location decisions of multinational firms. In the model, firms choose in which locations to pay the fixed costs of setting up production, taking into account potential complementarities among production locations. The firm's location...
