decompr: Global Value Chain Decomposition
Three global value chain (GVC) decompositions are implemented.
The Leontief decomposition derives the value added origin of exports by
country and industry as in Hummels, Ishii and Yi (2001). The Koopman,
Wang and Wei (2014) decomposition splits country-level exports into 9
value added components, and the Wang, Wei and Zhu (2013) decomposition
splits bilateral exports into 16 value added components. Various GVC
indicators based on these decompositions are computed in the
complimentary 'gvc' package.
