Motivated by increasing trade and fragmentation of production across countries since World War II, we build a dynamic two-country model featuring sequential, multistage production and capital accumulation. As trade costs decline over time, globalvalue-chain (GVC) trade expands across countries,...

A major feature of globalization has been the enormous increase in international flows of goods and services: countries are now trading much more with each other. In this article, the authors demonstrate the greater role vertical specialization is playing in these increased flows. Vertical...

Globalization has led to an enormous increase in international trade. Over the past 40 years, world exports as a share of output have doubled to almost 25 percent of world output. However, despite this enormous increase, economic evidence suggests that significant barriers to international trade...

The growth in the trade share of output is one of the most important features of the world economy since World War II. We show that an important propagation mechanism for this growth is vertical specialization. Simply put, vertical specialization occurs when imported inputs are used to produce...

Recent empirical research finds that pairs of countries with stronger trade linkages tend to have more highly correlated business cycles. We assess whether the standard international business cycle framework can replicate this intuitive result. We employ a three-country model with transportation...

The robust growth of the U.S. economy between 1996 and 1999 spurred U.S. demand for foreign goods and contributed to a surge in the U.S. trade deficit. An analysis of the effects of the expansion on the trade balance suggests that the economic boom can account for roughly a third of the sharp...
