About GTAP

Founded in 1992, and coordinated by the Center for Global Trade Analysis at Purdue University, the Global Trade Analysis Project (GTAP) is a network of 32,679 individuals engaged in quantitative analysis of 21st century challenges. A consortium of 31 leading national, international, and private institutions provides baseline financial support and strategic advice to the Center for Global Trade Analysis in support of GTAP. Guided by a philosophy of collaboration in domains of mutual benefit, notably data development, combined with an open marketplace for ideas in analytics, GTAP aims to advance high-quality quantitative analysis of global issues and facilitate deliberate decision-making. To this end, GTAP:

  1. Lowers barriers for conducting high-quality analysis of global issues

    Data - GTAP assembles, documents, and makes publicly available a suite of databases that are widely regarded as the gold standard for global economywide analysis.
    Models, tools, and software - GTAP develops and makes publicly available a suite of cutting-edge and fully documented models and tools and collaborates with leading analytical software providers and the open-source programming community in the application of those models.
    Training - GTAP offers regular training courses, ranging from introductory to advanced, to scaffold network members in the application of the data, models, and software.

  2. Conducts research on pressing issues with global ramifications

    While the bulk of GTAP-related research is conducted by GTAP Network members, the Center for Global Trade Analysis houses one of the largest groups of top-flight economywide modelers in the world. This unique concentration of skill is buttressed by sector expertise, notably in energy and food systems. Guided by a distinguished Scientific Council, GTAP researchers, often in collaboration with network members, address a range of issues including trade and industrial policy, energy transitions, climatic change, economic development, biodiversity preservation, pollution abatement, and the circular economy.

  3. Serves as a platform for discussion and dissemination of novel approaches and new ideas

    GTAP brings together thought leaders at the Annual Conference on Global Economic Analysis, fosters innovation through the peer-reviewed Journal of Global Economic Analysis, hosts a Virtual Seminar Series, and maintains an active presence on social media.

GTAP-related analytics are a regular feature in the world’s most prestigious scientific journals and inform a vast array of decision-making processes by governments, international organizations, and private entities around the world.
