Global Trade Analysis Project (GTAP)
The GTAP project is well known and valued among the modeling community. Coordinated by the Center for Global Trade Analysis, and housed in the Department of Agricultural Economics at Purdue University, GTAP produces analytical data bases, economic models, and innovative methodologies which have had a major impact on the sophistication of trade modeling. In fact, changes to its data bases explain many of the changes to the modeling results.
UNCTAD's Agriculture Trade Policy Simulation Model
The Trade Analysis Branch of the United Nations Centre for Trade and Development (UNCTAD) has developed its own global model to simulate scenarios from WTO negotiations on agriculture, covering 175 countries and some 36 different commodities. Designed to be user-friendly, with a graphical interface and extensive instructions, UNCTAD's Agriculture Trade Policy Simulation Model (ATPSM) is a tool intended for researchers and trade negotiators who may not have extensive training in modeling.
Centre d'études prospectives et d'informations internationals: Mirage Model
Centre d'études prospectives et d'informations internationals (CEPII) has developed the so-called Mirage model, a CGE model that boasts several innovations. A multi-region and multi-sector model, it incorporates imperfect competition, product differentiation by variety and by quality, and foreign direct investment, in a sequential dynamic set-up. It also draws upon a very detailed measure of trade barriers and of their evolution under given hypotheses.
