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...

We study the importance of international trade in structural change. Our framework has both productivity and trade cost shocks, and allows for non-unitary income and substitution elasticities. We calibrate our model to investigate South Korea's structural change between 1971 and 2005. We find...

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,...

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...

Dramatic changes are occurring in the nature of international trade. Production processes increasingly involve a sequential, vertical trading chain stretching across many countries, with each country specializing in particular stages of a good's production sequence. We document a key aspect of...

The growth in the trade share of output is one of the most important features of the world economy since World War II. The growth is generally thought to have been generated by falling tariff barriers worldwide. This thinking, however, does not square with standard static and dynamic...

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...
