Global Trade Analysis Project (GTAP)

The Global Trade Analysis Project (GTAP) is a global network of researchers and policy makers conducting quantitative analysis of international policy issues. GTAP is coordinated by the Center for Global Trade Analysis in Purdue University's Department of Agricultural Economics.

2025 Alan A. Powell Award

UNECA Logo

Regional integration is hard. Regional integration can be very beneficial. Regional integration is happening in Africa. And, the efforts of the UNECA, substantially spearheaded by Stephen, are a big reason why so much progress is being made. Alan’s legacy with GTAP enabled the UNECA and people like Stephen to have impact, and, that is what they have done, and will continue to do.

Thank you, UNECA, for your many important contributions to fostering regional integration in Africa.

2025-2028 Research Fellows

Jayson Beckman Jayson Beckman

For his contributions in promoting the GTAP Model through the impressive breadth and depth of his policy research. He has authored and co-authored over 100 hundred peer-reviewed journal articles, government reports, and other publications that utilize the GTAP Model and its variations to address questions of climate, trade, productivity, and other topics. To advance his work, Jayson often modified the model to make it better-suited for less common policy questions, with his inventions often benefiting other researchers.

Ole Boysen Ole Boysen

For his contributions to the CGE communities, particularly related to his research on demand system and international trade. He has developed extremely relevant methods to link CGE models to other tolls, including PE models and microsimulations, has contributed to the development of econometric techniques and the development of specific R packages for econometric analysis, and this year, spearheaded the initiative to bring the Pan-African Network for Economic Analysis of Policies (PANAP) Conference Participation Grant for African Researchers into the GTAP Conference.

2025-2027 Research Fellows

Emanuele Ferrari Emanuele Ferrari

For his contributions to data, including the EU tables currently used in GTAP, as well as a number of single-region SAMs for several African countries. Emanuele has carried out single and multi-country CGE analysis, often focusing on Africa, free trade, and agriculture, and along with Ole, plays an important role in the Pan-African Network for Economic Analysis of Policies, fostering international collaboration and capacity building.

Karen Thierfelder Karen Thierfelder

For being a steady contributor to GTAP through data, models, research, and training for decades.

2025-2027 Research Fellows

Luca Salvatici Luca Salvatici

For being widely recognized for his pivotal role in advancing the use of CGE models in trade policy analysis, foundational contributions to developing and applying the GTAP Model, co-developing the GTAP-VA module for global value chain analysis, and contributing to literature using the GTAP-Energy model, which he used to study carbon leakage and climate policy, and his recent work focused on developing a methodology to micro-found input-output data within the GTAP framework, as well as updating the GTAP-HS extension, which integrates GTAP with high-resolution tariff data.

2025-2 GTAP 101 Course
"Introduction to Computable General Equilibrium Modeling in the GTAP Framework"
September 1 - October 19, 2025


Cover image for Computable General Equilibrium Models
Dates/Deadlines (USA Eastern Time Zone)
Course Application March 10 - June 15
Enrollment Mid-July


Coursework based on:
Introduction to Computable General Equilibrium Models, 3e
by Mary E. Burfisher

The objective of the GTAP 101 course is to engage participants in an active, team-based process of learning about the GTAP computable general equilibrium (CGE) model and its use in applied economic policy analysis. The curriculum emphasizes an intuitive and graphical treatment of economic theory in the CGE model and provides structured experiences in running the standard GTAP Model, v7 within the RunGTAP software environment.
