%description
Two global-value-chain decompositions are implemented. Firstly, the
Wang-Wei-Zhu (Wang, Wei, and Zhu, 2013) algorithm splits bilateral gross
exports into 16 value-added components. Secondly, the Leontief
decomposition (default) derives the value added origin of exports by
country and industry, which is also based on Wang, Wei, and Zhu (Wang, Z.,
S.-J. Wei, and K. Zhu. 2013. "Quantifying International Production Sharing
at the Bilateral and Sector Levels.").
