 abstract = {This paper provides both a conceptual framework for decomposing a country’s gross exports into value-added components by source and a new bilateral database on value-added trade. Our parsimonious framework integrates all previous measures of vertical specialization and value-added trade in the literature. To illustrate the potential of the decomposition, we present a number of applications including re-computing revealed comparative advantages and constructing an index to describe whether a country-sector is likely in the upstream or downstream of global production chains.},
