GTAP Data Bases: Other Data and Models

Other GTAP Models

GTAP-AEZ modifies the standard GTAP model by spatially disaggregating land use and land cover in agriculture, pasture and forestry by agro-ecological zone (AEZ). It draws upon publicly available geospatial maps as well as state-of-the-art definition of AEZs from the FAO and IIASA.
GTAP-E is an extension of the GTAP framework (data base and model) used to evaluate costs of abatement and to assess the spill-over effects of greenhouse gases (GHG) abatement policies via international trade and sectoral interaction.
GTAP-GMig2 extends the GTAP framework to include bilateral labor migration data and is explicitly modeled to track the movement of workers and estimate the level of remittances. It is used in the analysis of labor migration issues.
GTAP-POV is another extension of the GTAP framework to analyze poverty impacts of global economic policies across a wide range of developing countries, in a way which enables systematic cross-country comparisons.
GTAP-Power Jeffrey Peters explains how the electricity sector plays a crucial role in the global economy.
Referencing the extension, GTAP-Power Data Base.
Land Use and Land Cover Data Base builds global land cover and land use databases for base years: 2004, 2007 and 2011. Unlike previous versions, the data is directly constructed from publicly available geospatial maps (circa 2000/01 at 5-minute grid resolution). These are then aggregated for each AEZ-region and updated to each base year using national level output price, land use and land cover information from FAOSTAT (2016). A FlexAgg program for this database is currently in development and will be available for each base year.

Other GTAP Data-based Models

CGEBox is a flexible, extendable and modular code basis for CGE modeling in GAMS drawing on the GTAP data base, combined with a powerful user interface based on GAMS Graphical User Interface Generator.
ENVISAGE model stands for Environmental Impact and Sustainability Applied General Equilibrium Model. It is designed to analyze a variety of issues related to the economics of climate change.
G-Cubed is a global intertemporal general equilibrium model that is a hybrid of a conventional CGE model and a DSGE model from macroeconomics. It has been extensively used for climate policy, trade policy, macroeconomic policy and demographic change.
G-RDEM is a GTAP-Based Recursive Dynamic CGE Model for Long-Term Baseline Generation and Analysis.
GEM-E3 is a recursive dynamic computable general equilibrium model that covers the interactions between the economy, the energy system and the environment. The world version of GEM-E3 is based on the GTAP Data Base.
GLOBE is a SAM based global CGE model calibrated using the GTAP Data Base.
GRACE stands for Global Responses to Anthropogenic Changes in the Environment. This is a computable general equilibrium model developed to analyse economic consequences of climate policy and impacts of climate change to the world economy.
GTAPinGAMs - There is also a version of the GTAP model written in GAMS called GTAPinGAMS which was developed by Tom Rutherford. These programs should be useful to economists who program in GAMS and wish to use GTAP in applied work. These programs include tools for translation of the GTAP files into GAMS readable form, GAMS programs for dataset aggregation, filtering and the imposition of alternative tax rates on trade or domestic transactions. The following publication in the Journal of Global Economic Analysis contains additional information.
Versions of GTAPinGAMs:
GTEM - The global trade and environment model is a dynamic multi region, multi sector, general equilibrium model of the world economy.
ICES (Intertemporal Computable Equilibrium System) model is a recursive dynamic general equilibrium model developed with the main (but not exclusive) purpose to assess the final welfare implication of climate change impacts on world economies.
Linkage - This is a global dynamic computable general equilibrium (CGE) model maintained by the World Bank to support global trade policy analysis.
MAGNET has the standard GTAP model at its core with all extensions added in a modular fashion. The Modular Applied GeNeral Equilibrium Tool has been used extensively in agricultural, environmental and trade policy analysis.
Manage model is a (recursive) dynamic single country computable general equilibrium (CGE) model designed to focus on energy, emissions and climate change.
Mirage - This is another a multi-region, multi-sector computable general equilibrium model, devoted to trade policy analysis. It incorporates many features in a sequential dynamic set-up.
MyGTAP is a user-based initiative to extend the Standard GTAP model to include new features and data, providing the means to analyze country level impacts of international trade policy on households and governments.
WorldScan - WorldScan is a recursively dynamic general equilibrium model for the world economy, developed for the analysis of long-term issues in international economics.

Other Models

Centre of Policy Studies (CoPS) and Gempack - Gempack is a General equilibrium modelling software developed at CoPS and used by CGE modellers world-wide. The standard GTAP Model is implemented using Gempack. The Centre of Policy Studies also develops and maintains a number of single country comparative static and dynamic models for Australia and many other countries. Crusoe Suite - If you have sets, flows and parameter files acceptable to the standard GTAP Model, you can use the freeware CRUSOE45 program to extract from the GTAP data files in a new file containing data for one region only. The extracted data might be used for a single country CGE model. CRUSOE is available from the CoPS website.
