%description
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. --- References: --- Hummels, D., Ishii, J., & Yi, K. M. (2001).
