"The Similarities and Differences among the Three Major Global Inter-Country Input-output Database and their Implications for Trade in Value-added Estimates"
by Wang, Zhi, Christophe Degain, Jones Lin and Xin Li

This paper compares three publicly accessible global inter-country Input-output (ICIO) databases constructed by WIOD, GTAP and OECD. We first harmonize the three databases into the same country and sector classification and check their consistence with each country’s GDP by expenditure accounts, compute the differences between the three databases in major economic variables, including gross outputs, direct value-added, domestic and imported intermediate inputs and final demand, and bilateral gross trade flows. Then we estimate major trade in value-added indicators, decompose each country’s gross exports into various value-added and double counted components, using the method proposed by Koopman, Wang and Wei (2012), and discuss the similarities and differences of these estimates among the three databases. We conclude the paper by a discussion of directions of further improvement of such type global ICIO database.
