Title: Global Value Chain Decomposition of Inter-Country Input-Output
        Tables
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, and also provides a corrected version of the
        (biased) Koopman-Wang-Wei decomposition. It is the recommended
        method and reproduces the Stata 'icio' command. --- References:
