The war in Ukraine has sent shock waves through global energy and agricultural markets. Dr. Maksym Chepeliev, a Ukrainian Research Economist with Purdue Center for Global Trade Analysis, recently presented his paper on the economic impacts of an EU moratorium on energy imports from Russia to the EU Parliament. Ken and Halee talk with Maksym about his research and the role of the Purdue Community in supporting Ukrainians.

"Introduction to Computable General Equilibrium Modeling in the GTAP Framework"
September 5 - October 23, 2022

Cover image for Computable General Equilibrium Models
Dates/Deadlines (USA Eastern Time Zone)
Course Application March 14 - June 19
Enrollment late July

Coursework based on:
Introduction to Computable General Equilibrium Models, 2e
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.

2022 GTAP Firm Heterogeneity Course
"Applied Policy Analysis with Advanced Trade Theories"
October 24 - December 11, 2022

Dates/Deadlines (USA Eastern Time Zone)
Applications May 2 - August 7
Acceptance Notifications Early September
The GTAP-HET Course is a hands-on, fully-online course developed to provide professional economists and Masters/PhD students with the tools and skills necessary to use advanced trade theories in trade policy analysis. During the course, participants will:
  • learn about the Melitz model of heterogenous firms, viewed as a more general version of the Krugman model of monopolistic competition, and Armington model with perfect competition;
  • develop skills to use the GTAP Firm Heterogeneity (GTAP-HET) Model where Armington, Krugman, and Melitz models are nested in the GTAP computable general equilibrium framework;
  • conduct trade policy experiments and interpret simulation results using the GTAP-HET Model in team-based research projects.
