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 construct a new database which covers production and trade in 136 primary commodities and 24 manufacturing and service sectors for 145 countries. Using this new more granular data, we estimate spillover effects from plausible trade fragmentation scenarios in a new multi-country, multi-sector,...

We study cross-country differences in price and quality in the market for semiconductor wafer manufacturing services. Using a proprietary transaction-level data set, we document i) substantial constant-quality price differences across suppliers, and ii) shifts toward lower priced suppliers....

This paper uses “centrality” metrics to reflect position with Global Value Chains (GVCs). Central sectors reflect those that are highly connected (both directly and indirectly) and influential within globalproduction networks, whereas peripheral sectors exhibit weak linkages and are less...

This paper aims to examine the changes in global value chains (GVCs) in the years 2020-2022 (times of the COVID-19 pandemic) compared to 2019 (last year before the pandemic). GVCs are illustrated by diagrams based on the statistics on international trade measured by value-added exports and...

Does fragmentation of production affect the trade patterns of different countries in similar ways? In contrast with current theories of vertical specialization, attempts to provide empirical evidence on this question have been based, in the vast majority of cases, only on a statistical analysis...
