Dates/Deadlines (USA Eastern Time Zone)
Course Application March 22 - June 27
Acceptance Notifications 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.

2021 GTAP Firm Heterogeneity Course
"Applied Policy Analysis with Advanced Trade Theories"
October 4 - November 21, 2021

Dates/Deadlines (USA Eastern Time Zone)
Applications March 15 – July 18
Acceptance Notifications August
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.
