The Center for Global Trade Analysis is pleased to partner with AGRODEP, facilitated by IFPRI, to offer this event.

The goal of the conference is to promote the exchange of ideas among economists conducting quantitative analysis of global economic issues. Particular emphasis will be placed on applied general equilibrium methods, data, and application. Related theoretical and applied work is also welcome.

A number of scholarships will be available for presenters currently residing in Africa.

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

The objective of GTAP 101 is to engage participants in an active, team-based process of learning about the GTAP CGE model and its use in applied economic policy analysis. The curriculum is geared to advanced undergraduates, graduates and professionals. Following the course, participants will be entry-level modelers and more informed consumers of CGE-based analyses.
GTAP 8 globe icon GTAP 8 Data Base
The centerpiece of the Global Trade Analysis Project is the GTAP Data Base, a fully documented, publicly available global data base, which contains bilateral trade information, transport and protection linkages. The current release, GTAP 8, boasts dual reference years of 2004 and 2007 as well as 129 regions and 57 sectors.

GTAP 8 Satellite Data and Utilities
The GTAP Satellite Data and Utilities below have been developed for sale with the GTAP 8 Data Base and allow users to more easily use and adapt the full suite of GTAP Models for analysis of global trade and environmental issues.

We are pleased to announce the public release of non-CO2 data base for GTAP 8 Data Base. Special thanks to the contributors: Amer Ahmed, Zeynep Burcu Irfanoglu, Steve Rose and Tom Hertel, for their efforts in finalizing this release.

Current Composition
  • GDyn Data Base
  • GMig2 Data Base
  • GTAP-E Data Base
  • Land Use and Land Cover Data Base
  • GTAP Non-CO2 Emissions Data Base

22nd Annual Short Course in Global Trade Analysis
"Introduction to Applied General Equilibrium Analysis in a Multi-Region Framework"
West Lafayette, Indiana, USA     August 2-8, 2014

Purdue University
Purdue University
Notable Dates/Deadlines (EST)
Application March 20 (Expired)
Acceptance Notifications April (On going)
Online Course May 19 - July 20
The course consists of a mix of daily lectures, lab assignments and informal discussions designed to introduce participants to the basic features of the GTAP Model and data base allowing participants to leave with the capability of designing, conducting and analyzing their own simulations. The objectives of the course are:
  • To introduce participants to a standardized framework for conducting global policy analysis in an applied general equilibrium setting

  • To provide participants with ample hands-on training with software that has been tailored to global economic analysis

  • To give participants the opportunity to interact with economists working on global trade and resource use issues
