"The Similarities and Differences among Three Major Inter-Country Input-Output Databases and their Implications for Trade in Value-Added Estimates" by Jones, Lin, Zhi Wang, Christophe Degain and Xin Li Abstract This paper compares three inter-country input-output (ICIO) databases with official statistics as well as their respective results for trade in value added (TiVA) indicators. The three ICIO databases under review have been constructed by the Global Trade Analysis Project (GTAP), the Organization for Economic Cooperation and Development (OECD), and the World Input Output Database (WIOD) project. First, the three ICIO tables are harmonized into the same country and sector classification, and their consistencies with each country’s GDP (based on expenditure accounts) and balance of payments figures are checked. Then, the differences between the three databases in major economic variables, including gross output, value-added, domestic and imported intermediate inputs, as well as final demand are presented. Next, major TiVA indicators based upon the three ICIO tables are estimated, and each country’s gross exports are decomposed into various value-added and double counted components, using the method proposed by Koopman, Wang and Wei (2014). The similarities and differences of the estimates among the three databases are discussed. The paper concludes with suggestions on the directions of how the construction of ICIO databases could be improved. Note: the ICIO data used for this paper include the latest revisions made by GTAP, the OECD and the WIOD team at the completion of the paper. All trade data used in the study include both goods and services. |
