Global Trade and Analysis Project (GTAP) Model
GTAP-E is built on the GTAP model of global trade. GTAP (Global Trade Analysis Project) is a multi-regional AGE model which captures world economic activity in a few dozen different industries of more than 60 regions. GTAP-E allows modeling the energy-economy-environment-trade linkages by incorporating energy substitution into the standard model. In addition, GTAP-E incorporates carbon emissions from the combustion of fossil fuels and provides for a mechanism to trade these emissions internationally.

"The standard GTAP Model is a multiregion, multisector, computable general equilibrium model, with perfect competition and constant returns to scale. Innovative aspects of this model include:
- The treatment of private household preferences using the non-homothetic CDE functional form.
- The explicit treatment of international trade and transport margins. Bilateral trade is handled via the Armington assumption.
- A global banking sector which intermediates between global savings and consumption.
- The GTAP Model also gives users a wide range of closure options, including unemployment, tax revenue replacement and fixed trade balance closures, and a selection of partial equilibrium closures (which facilitate comparison of results to studies based on partial equilibrium assumptions)."
