Current Highlights

2026 Research Fellow Hall of Fame

Frank van Tongeren Frank van Tongeren

Frank has been deeply involved with GTAP since its inception. Following his participation in the GTAP Short Course, he returned the next year as an instructor. He served as a GTAP Advisory Board Member since 1996, first on behalf of LEI and subsequently on behalf of the OECD. In 1999, he received the Alan A. Powell Award, recognizing outstanding service on the GTAP Advisory Board. In 2001, Frank led a major review of global models of agriculture and the environment and has contributed a very long list of GTAP resources and publications. Between 2006-2024 Frank held positions at the OECD in Paris where he led policy analysis and modelling in the Directorate for Trade and Agriculture, where his team developed the OECD trade model METRO. Frank currently serves as Vice Chair of the GTAP Scientific Council. His career-long contributions to the community make him a most worthy recipient of induction into the GTAP Hall of Fame.

2026 Research Fellow Hall of Fame

Niven Winchester Niven Winchester

Niven has been active in the GTAP Network since 2005. He works at the interface of climate policy, energy systems and the economy and had a distinguished career with the MIT Joint Program on the Science and Policy of Global Change before returning to New Zealand, where he currently serves as a Senior Fellow with Motu Economic and Public Policy Research. Niven has been honored three separate times as a GTAP Research Fellow, each with a term of three years, recognizing the excellence of his research as well as his data base contributions. Within our community, Niven is most widely known for starting the Journal of Global Economic Analysis, which he co-edits with Tom Hertel. Niven’s tireless work with the JGEA has ensured that this journal is open-access and free to all, including those wishing to make a submission. To accomplish this, he navigated the Open Journal System, which allows us to operate independently of commercial publishing houses. It’s fair to say that without Niven, there would be no JGEA!

2025 Alan A. Powell Award

European Commission - Joint Research Centre

The JRC has made significant contributions to the GTAP Data Base by providing high-quality input-output tables for European Union Member States, strengthening the global relevance of GTAP for researchers and policymakers worldwide. Beyond data contributions, the JRC actively uses the GTAP Data Base and model to conduct research on agricultural, climate, and energy policies. The JRC is also a co-host of the Pan-African Network for Economic Analysis of Policies, an initiative that fosters collaboration between researchers and policymakers in and for Africa. The JRC's longstanding partnership, technical innovation, and commitment to collaborative data development exemplify the spirit of service and international cooperation that the Alan A. Powell Award was created to honor.

Thank you, JRC, for your many important contributions to GTAP!

2025-2028 Research Fellows

Janine Dixon Janine Dixon

In recognition of her outstanding leadership and internationally significant contributions to CGE modeling, labor market forecasting, and policy analysis. Through her leadership at CoPS, pioneering work on CGE theory and microsimulation methods, and influential public policy engagement in Australia and abroad, she has advanced both the practical application and global impact of economic modeling research.

Ken Itakura Ken Itakura

For his influential contributions to international trade policy analysis and the advancement of CGE modeling, particularly through his work on the static and dynamic GTAP Models. His leadership in developing non-tariff measures databases and his widely recognized analyses of major Asia-Pacific trade agreements, including CPTPP, RCEP, and ASEAN integration, have significantly strengthened the field of policy-oriented trade research.

2025-2027 Research Fellows

Yaghoob Jafari Yaghoob Jafari

For his contributions to CGE modeling, international trade, and agri-food systems research. As an active member of the GTAP Network with a strong record of peer-reviewed publications and conference contributions, his work has advanced applied economic modeling and policy analysis across multiple domains.

Maria Latorre Maria Latorre

In recognition of her long-standing and highly impactful contributions to applied CGE modeling and international trade policy analysis, particularly through her work on foreign direct investment, dynamic modeling, and major policy issues such as Brexit, EU trade agreements, and the Inflation Reduction Act. Her sustained engagement with the GTAP Network and dedication to training and mentoring new modelers have significantly strengthened the bridge between CGE research and real-world policy application.

2026-2 GTAP 101 Course
"Introduction to Computable General Equilibrium Modeling in the GTAP Framework"
August 31 – October 18, 2026


Cover image for Computable General Equilibrium Models
Dates/Deadlines (USA Eastern Time Zone)
Course Application March 9 - June 28
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.

GTAPinR Course
"Running the GTAP Model using R packages HARr and tabloToR"
GTAPinR

The GTAPinR Course is a self-paced, fully online course aimed at empowering GTAP users with practical tools in R statistical software to enhance simulation analysis for policy making through improved processing of economic model outputs.

2026 GTAP Modeling Trade Policy Course
"Applied Analysis on Trade Policy Instruments"
October 12 – November 29, 2026


GTAP Modeling Trade Policy (MTP) Logo
Dates/Deadlines (USA Eastern Time Zone)
Applications April 20 - July 26
Enrollment Late Aug
The GTAP Modeling Trade Policy (MTP) Course gives professionals and students hands-on training in trade policy analysis using the GTAP computable general equilibrium model (v7). Participants build practical skills in designing policy experiments, applying tariff and non-tariff measures, and interpreting results — grounded in core economic theory and the RunGTAP software environment. The course culminates in team projects assessing real-world trade policy scenarios, including PTA liberalization and tariff hikes, to evaluate their economy-wide and sectoral implications.
2027 Short Course in Dynamic Global Trade Analysis
"Applied General Equilibrium Analysis using a Dynamic Multi-Region Model"
January 18 - March 12, 2027   |   Purdue University

Purdue University
Purdue University
West Lafayette, IN, USA
Dates/Deadlines (USA Eastern Time Zone)
Applications April 13 – August 30, 2026
Enrollment Late September 2026
Phase 1 January 18 – February 28, 2027
Phase 2 March 8-12, 2027

The objective of this course is to introduce participants to dynamic economic analysis in an applied general equilibrium setting. This course is designed to provide participants with ample hands-on training with software that has been tailored for undertaking analysis using a dynamic recursive model. Participants will interact with economists working on global trade and environmental issues using a dynamic framework. The end goal of the course is for participants to leave with the capability of conducting and analyzing their own dynamic simulations.
