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.

Bringing People Together

Advancing Policy Through Collaboration

One of the greatest strengths of the annual GTAP Conference is its ability to bring together researchers and policymakers from around the world who share a commitment to evidence-based policy analysis. The 2026 GTAP Conference, held in Kyoto, provided a forum for 250 participants from 39 countries to exchange ideas, build professional networks, and develop new collaborations around pressing global challenges. GTAP's broader mission is rooted in lowering barriers to high-quality analysis and creating a platform for the discussion and dissemination of new ideas, bringing together a global network of more than 34,000 members.

An example of this community-building occurred at this year's conference, where two participants from Uzbekistan, Valijon Turakulov of Inha University Tashkent and Fazliddin Shamsiev of the Ministry of Economics and Finance of Uzbekistan, met for the first time. Although both are engaged in quantitative economic policy research focused on Central Asia, it was the GTAP Conference that created the opportunity for them to connect. Their story illustrates how the GTAP Network helps foster communities of researchers and policymakers from countries that may have relatively small analytical communities, enabling connections that can grow into future collaborations and strengthen policy-relevant research both nationally and internationally.

This connection was especially timely as Uzbekistan advances toward membership in the World Trade Organization. Uzbekistan first applied to join the WTO in 1994, but its accession process gained renewed momentum when active negotiations resumed in 2020. The country is working toward concluding the process in 2026. As the country evaluates market-access commitments, regulatory reforms, and the economy-wide implications of deeper integration into global trade, GTAP-based analysis can provide valuable evidence on potential impacts across industries, households, trade flows, and the broader economy. Such analysis can help researchers and policymakers identify opportunities, anticipate adjustment challenges, and support informed decision-making throughout the accession process and beyond.

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.
