The purpose of this note is to provide an exhaustive reference for those interested in learning more about the Constant Elasticity of Substitution (CES) function and its use in the representation of producer behavior in the GTAP Model. Particular attention is paid to the role of technical change...

While constructing a new baseline for the GDyn model, we spent a lot of time collecting projections and deciding which data to choose. We also developed programs to aggregate projections to any specific geographical aggregation of the GTAP Data Base. In order to help researchers in the...

The land-use augmented version of the GTAP Data Base has been used for a wide variety of applications (Hertel, Rose, & Tol, 2009). The original GTAP-AEZ database incorporated geospatial data on land use into the version 6 GTAP Data Base, with a benchmark year of 2001. The methodology for...

A recent World Bank research project has generated an annual time series of distortions to agricultural incentives over the past half century for 82 countries, the majority of which are low-and middle-income countries. In this memorandum, the current GTAP version 8 Data Base may be modified to...

From time to time, members of the GTAP network compare GTAP data with official statistics from national and international sources. This has recently been done for the GDP statistics in GTAP, v.8 (Wang et al., 2013), suggesting that there were significant discrepancies between GTAP statistics and...

No one thought China’s high growth rates would persist forever, or that multinational firms would always keep pouring into the Chinese market, eager to establish operations regardless of local conditions. Economic convergence ensures that there will be a cooling off as wages rise and expected...

A global bilateral multi-region multi-sector foreign direct investment (FDI) stocks and flows database has been contributed to GTAP by Houssein Boumellassa, Christophe Gouel and David Laborde from CEPII (Centre d'Etudes Prospectives et d'Informations Internationales) as a result of a project...

Year 2004 emissions were estimated by applying annual growth rates to the detailed year 2001 emissions data (Rose et al., 2007) that was the input dataset for the GTAP version 6 non-CO2 emissions (Rose and Lee, 2009). Two methodologies were applied: one for methane (CH4) and nitrous oxide (N2O),...

This paper presents a method that was employed in order to make the available fourteen household income survey data sets compatible with the data in the GTAP version 5 database. The first step of the method was the imputation of the unobservable returns to GTAP factors from the reported data....

The memorandum documents the initial preparation of energy volume data for release 7 of the GTAP Data Base.
