GTAP Models: Current GTAP Model
Standard ModelThe 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 was initially documented in the GTAP Book. Recent changes in the structure can be found below:

- Version history: The first model version was GTAP.TAB 2.2a (GTAP 94). It is documented in the GTAP Book. Since 1994, 5 major versions have been released. A complete version history since 1994 may be downloaded.
Mary Burfisher, has published a hands-on book, Introduction to CGE Models, that new GTAP users might also find useful.

Applications and Extensions to the GTAP Model
The standard GTAP Model is amenable to modifications. Many of these modifications are documented in the GTAP Technical and Working Paper Series as well as in GTAP Applications. Key areas of current research at the Center include the development of models and data bases to examine issues related to environmental and energy issues, poverty and migration.
