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.

2020-2023 Research Fellows

Jonas Luckmann Jonas Luckmann

For extensive work on the broader field of CGE, specifically in water modelling, as well as his contributions to the GTAP Data Base.

Simon Mevel Simon Mevel

For his contributions to knowledge and policy making using the GTAP Data Base, through leading the modeling work using GTAP at the UN Economic Commission for Africa, and his outstanding leadership in designing training for African researchers and policy makers.

2020-2023 Research Fellows

Roberto Roson Roberto Roson

For him seminal work on climate change, notably estimating the economic impacts that climate change may have on specific drivers such as tourism revenues, labor productivity, etc., as well as his body of work looking at water issues, firm heterogeneity and risk, and his most recent work that has provided a deep dive into the foundations of applied dynamic CGE modeling and how to think about changing preferences in consumer demand, technology parameters in production and the role of labor productivity in structural change.

The Board also approved to name the following into the GTAP Hall of Fame:

Kenichi Kawasaki Kenichi Kawasaki

For outstanding leadership in the development of the GTAP community across the Asia-Pacific Rim, as well as his contributions to cutting edge analysis of global trade policy issues.

The GTAP version 10A Multi-Region Input Output (MRIO) Data Base

by Carrico, Caitlyn, Erwin Corong and Dominique van der Mensbrugghe

This memorandum describes the GTAP version 10A Multi-Region Input Output (GTAPMRIO) Data Base. GTAP-MRIO extends the standard GTAP Data Base (Aguiar et al., 2019) by additionally distinguishing bilateral trade and tariff flows by agents or so-called end-users,namely: firms, private household, government and investors. In constructing GTAP-MRIO,we employ the methodology in Carrico (2017) and update it in four ways. First, an updated concordance table is used. Second, the International Trade Centre (ITC) Market Access Map (MAcMap) data is directly used in lieu of the TASTE utility which is also based on MAcMap. Third, the optimization programs are updated to take advantage of grid facility in GAMS, thereby reducing MRIO data build time by 90 percent and easing MRIO data construction at the full dimensionality of GTAP data. Fourth, accompanying GTAPAgg2 and FlexAgg packages are provided to aid researchers aggregate the GTAP-MRIO data.

Development of the Air Pollution Database for the GTAP Data Base Version 10A

by Maksym Chepeliev

The purpose of this note is to document data sources and steps used to develop the air pollution database for the GTAP Data Base Version 10A. Emissions for nine substances are reported in the database: black carbon (BC), carbon monoxide (CO), ammonia (NH3), non-methane volatile organic compounds (NMVOC), nitrogen oxides (NOx), organic carbon (OC), particulate matter 10 (PM10), particulate matter 2.5 (PM2.5) and sulfur dioxide (SO2). The dataset covers four reference years (2004, 2007, 2011 and 2014). EDGAR Version 5.0 database is used as the main data source. To assist with emissions redistribution across consumption-based sources, IIASA GAINS-based model and IPCC-derived emission factors are applied. Each emission flow is associated with one of the four sets of emission drivers: output by industries, endowment by industries, input use by industries and household consumption.

2020 GTAP Firm Heterogeneity Course
"Applied Policy Analysis with Advanced Trade Theories"
October 5 - November 22, 2020


GTAP-HET
Dates/Deadlines (USA Eastern Time Zone)
Applications April 6 - July 19
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.
