Public Availability
The current GTAP Data Base may be purchased by anyone interested in using it. Proceeds help to offset the cost of producing the next release. This permits users to share in development costs and it prevents needless duplication of effort in creating this public good. Older versions are available free of charge (except for the preceding version) look for them in the archives.

Regular Updates
The GTAP Data Base is updated every few years. The release used in the GTAP book is Version 2.

Broad Participation
The network of GTAP users represents an excellent resource for improvement of the GTAP Data Base. Contributors have access to a number of concordances to help match data to the GTAP sector and commodity detail. An added benefit from broad participation is extensive scrutiny of the GTAP Data Base.

Comparative Advantage
By making the GTAP Data Base available and offering to incorporate improvements offered by members of the network, each individual is able to work to his/her own comparative advantage while capitalizing on the contributions of others.

Documentation and Replicability
The GTAP Data Base is fully documented. One requirement for new contributions to the GTAP Data Base is that the sources and procedures used to create them be provided along with the data. In addition, the GTAP software is designed to permit applications to be readily replicated by others. Together, these two features are designed to enhance the credibility and comparability of global trade analysis. Specific features of the data are also discussed in a number of frequently asked questions. Many are drawn from discussions on the GTAP-L mailing list.

How to Contribute to GTAP?
While the GTAP Data Base is constructed by the Center for Global Trade Analysis, the data is supplied by the GTAP Network - consisting of individuals, agencies and institutions from around the world. The Network of GTAP users represents an excellent resource for improvement of the GTAP Data Base. Those who identify areas for improvement or extension of the GTAP Data Base are free to make this available to GTAP staff in order to have it considered for incorporation into the next release. Visit the How to Contribute? section for more information.
