"Augmenting GTAP Database: Are the data on intra institutional transactions important?"
by Sonmez, Yontem, Scott McDonald and Terrie Walmsley

The Global Trade Analysis Project’s (GTAP) database is used to calibrate the vast majority of global computable general equilibrium (CGE) models. But all versions of the database have been parsimonious in their coverage of intra institutional transactions within and between regions; consequently domestic institutions – private households, (incorporated) enterprises and government - neither pay income taxes nor save and they are not recipients of incomes or transfers from other regions. Some of the constraints imposed by these limitations of the GTAP database have been partially addressed; McDougall and Hagemejer (2009) seek to include incomes taxes paid by households and enterprises as taxes paid factors, Walmsley et al., (2007) include details on labour incomes from abroad as part of the GMig satellite accounts, and McDonald and Sonmez (2004) augmented the current accounts so as to separate out the non trade balance elements from the balance on the capital account.
The objectives of this study are to augment version 7.1 of the GTAP database and provide a method for augmenting future versions of the GTAP database. The process of augmentation will take place within a Social Accounting Matrix (SAM) representation of the GTAP database and will preserve the majority of the key macroeconomic aggregates that are embedded within version 7.1 of the GTAP database. A longer term objective is to provide a method whereby GTAP can incorporate a wider range of macro economic aggregates into the generation of the database. This aspect of the research will involve the development of a method whereby a complete and consistent global macro (aggregate) SAM can be devised from available and comparable data sources – primarily World Bank and IMF.
