icio: Global Value Chain Decomposition of Inter-Country Input-Output
Tables
Four global value chain (GVC) decompositions of gross exports
from inter-country input-output tables are implemented. The Leontief
decomposition derives the value added origin of exports by country and
industry, as in Hummels, Ishii and Yi (2001) <doi:10.1016/S0022-1996(00)00093-3>.
The Koopman, Wang and Wei (2014) <doi:10.1257/aer.104.2.459> decomposition
splits country-level exports into 9 value added components, and the Wang,
Wei and Zhu (2013) <doi:10.3386/w19677> decomposition splits bilateral
exports into 16 value added components. The Borin and Mancini (2019)
<doi:10.1596/1813-9450-8804> 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 'icio'
command for 'Stata' described in Belotti, Borin and Mancini (2021)
<doi:10.1177/1536867X211045573>.
