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). 
The GTAP Model was initially documented in the GTAP Book. Recent changes in the structure can be found below:
