Abstract: We developed a method to construct a global ICIO table from version 8 GTAP database as well as detailed trade data from UN COMTRADE, and two additional IO tables for major emerging economies where processing exports are a large portion of their external trade. We integrate the GTAP database and the additional information with a quadratic mathematical programming model that (a) minimizes the deviation of the resulting new data set from the original GTAP data, (b) ensures that supply and use balance for each sector and every country, and (c) keeps all sectoral bilateral trade flows in the GTAP database constant. Bilateral and aggregate reliability indexes are computed for each GTAP sectors and end use categories which are used to control the relative amount of adjustment for each end-use categories within each original bilateral trade flows from the GTAP database. The new database covers 63 countries/regions and 41 sectors for 2004 and 2007 two years.
