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 Short Course in Dynamic Global Trade Analysis
"Applied General Equilibrium Analysis using a Dynamic Multi-Region Model"
January 20 - March 14, 2025   |   Purdue University

Purdue University
Purdue University
West Lafayette, IN, USA
Dates/Deadlines (USA Eastern Time Zone)
Applications April 15 – August 11, 2024
Enrollment September 2024
Phase 1 January 20 – March 2, 2025
Phase 2 March 10-14, 2025

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.

2024 GTAP Preferential Trade Agreements Course
"Applied Policy Analysis on Preferential Trade Agreements"
September 9 - October 20, 2024


GTAP Preferential Trade Agreements (PTA) Logo
Dates/Deadlines (USA Eastern Time Zone)
Applications March 18 - June 23
Enrollment Late July
The GTAP PTA Course is designed to provide professionals and students with hands-on, applied training in the analysis of preferential trade agreements (PTAs) using the GTAP computable general equilibrium model version 7. The objectives of the GTAP PTA course are to provide participants with an opportunity to develop their applied skills in the design of PTA experiments, the implementation of changes in tariff and non-tariff barriers, and the analysis of model results. The curriculum emphasizes an intuitive treatment of economic theory, provides structured experiences in manipulating and running the standard GTAP model within the RunGTAP software environment, and culminates in team-based research projects. At the end of the course, participants will have developed skills in the analysis of tariff and non-tariff liberalizations in a PTA.
2024-2 GTAP 101 Course
"Introduction to Computable General Equilibrium Modeling in the GTAP Framework"
September 2 - October 20, 2024

Course Application March 11 - June 16
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.

Meeting Global Challenges Together

Food. Water. Energy.

Three basic needs. But getting these necessities to the right places, at the right times, in the right amounts, without harming people or the environment, is a monumental task. And some of the conditions of modern life — climate change, war, pandemics — have made it even more difficult.
