The R package "decompr" implements two export decomposition
algorithms. Firstly, the Wang-Wei-Zhu (Wang, Wei, and Zhu 2013) algorithm
splits bilateral gross exports into 16 value added components. Secondly,
the Source decomposition algorithm derives the value added origin of
exports by country and industry, which is also based on Wang, Wei, and Zhu
(2013).

Global Value Chains Decomposition (Wang-Wei-Zhu and Leontief)

Two Global Value Chains 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 (2013).

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.").
