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.

2022-2025 Research Fellows

Alessandro Antimiani Alessandro Antimiani

For his many contributions to the GTAP Data Base, GTAP Technical Papers/Journal of Global Economic Analysis, and for being active in the GTAP policy scene in Brussels.

Heleen Bartelings Heleen Bartelings

For her many contributions to the MAGNET team and consortium, which has led to increasing the profile of what CGE analyses can offer policymakers and international institutions.

2022-2025 Research Fellows

Wolfgang Britz Wolfgang Britz

For his major contributions to modular CGE models and systems combining different model types such as GTAP and CAPRI, and also contributing to the methodological development of model linkage and meta-modeling, and his current work on a re-cursive dynamic variant of CGEBox for long-term baseline construction.

James Giesecke James Giesecke

For his CGE contributions in regional modeling, tax analysis, finance, and disaster analysis, and supporting GTAP through the Centre of Policy Studies by allocating time for the GEMPACK team to service GTAP through software development, training, and support; and growing the global community of CGE modellers by promoting CoPS’ international CGE projects and training efforts and providing databases created as part of CoPS’ global modelling activities to the GTAP Data Base effort.

2022-2025 Research Fellows

Maros Ivanic Maros Ivanic

For his work on improving the GTAP tools and making them accessible to more researchers through linking WiNDC with GTAP, developing a GTAP in R model, reverse-engineering HAR and SL4 files to allow GTAP-related analysis in open-source systems, and the linking of GTAP with a solver in R to allow for higher-order optimization, as well as his contributions to numerous research projects, including using GTAP to analyze the EUs Farm to Fork policy.

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.
