Title: Global Value Chain Decomposition
Description: Four 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. The Borin and
    Mancini (2019) decomposition splits country-, sector- or bilateral-level
    exports into up to 13 value added and GVC components. Various GVC
    indicators based on these decompositions are computed in the
    complimentary 'gvc' package.
