There are currently three "Consortium Members At Large" – Joseph Francois, Mark Horridge,{{cite web |title=Mark Horridge |url=https://www.copsmodels.com/jmh.htm |website=copsmodels.com |publisher=Victoria University, Melbourne |accessdate=9 March 2019}} and Brian O'Neill,{{cite web|title=Climate Change Expert Joins Korbel's Pardee Center|url=https://www.du.edu/news/climate-change-expert-joins-korbels-pardee-center|website=du.edu|publisher=University of Denver|date=7 March 2019|accessdate=9 March 2019}} who represent the broader scientific community. The primary database is essentially a multi-year form of a multi-region input output (MRIO) database supplemented by national macroeconomic data, though extensive satellite datasets cover other measures that are linked to the economic flows in the core database, including trade policies, greenhouse gas emissions, energy use, migration flows, and land use patterns.{{cite web |title=GTAP Data Bases: GTAP Satellite Data and Utilities |url=https://www.gtap.agecon.purdue.edu/databases/Utilities/default.asp |website=www.gtap.agecon.purdue.edu/ |publisher=Purdue University |accessdate=9 March 2019}} While from its inception the database was closely tied to the computable general equilibrium (CGE) research community, in recent years the database has also been at the center of greenhouse gas emissions accounting exercises,{{cite journal|last=Peters|first=G.P. |display-authors=et al|title=Growth in emission transfers via international trade from 1990 to 2008|journal=PNAS|year=2011|volume=108|issue=21|doi=10.1073/pnas.1006388108 |pages=8903–8908 |pmid=21518879 |pmc=3102371|doi-access=free }}{{cite journal |last1=Fernandez-Amador |first1=Octavio |display-authors=et al |title=Empirical estimates of the methane–income elasticity |journal=Economics Letters |date=2018 |volume=171 |issue=October |pages=137–139 |doi=10.1016/j.econlet.2018.07.012 |s2cid=54533320 |url=http://www.wti.org/media/filer_public/9b/c6/9bc6d871-bd50-4142-8a90-fe29aef39f28/wti_wp_04_2017_empirical_estimates_of_the_methaneincome_elasticity.pdf }}{{cite journal|last=Peters|first=G.P.|title=From Production-based to consumption-based national emission inventories|journal=Ecological Economics|year=2008|volume=65|issue=1|doi=10.1016/j.ecolecon.2007.10.014|pages=13–23}}{{cite journal |last1=Fernandez-Amador |first1=Octavio |display-authors=et al |title=Carbon dioxide emissions and economic growth: An assessment based on production and consumption emission inventories |journal=Ecological Economics |date=2017 |volume=135 |issue=May |pages=269–279 |doi=10.1016/j.ecolecon.2017.01.004 }} and related assessments of resource use.{{cite journal |last1=Sumaila |first1=U.

In addition to the multinational effort needed to update and expand the project database, the Center for Global Trade Analysis also offers courses on practical, model-based economic policy analysis. This includes courses on basic computational modelling and dynamic general equilibrium modelling.{{cite web |title=Short courses in global trade analysis |url=https://www.gtap.agecon.purdue.edu/events/Short_Courses/default.asp |website=gtap.agecon.purdue.edu |publisher=Purdue University |accessdate=9 March 2019}} The standard GTAP Model, which serves as a maquete or framework model linking the database to a basic general equilibrium system, was developed with the GEMPACK suite of software{{cite journal |last1=Corong |first1=Erwin L. |display-authors=et al |title=The Standard GTAP Model, Version 7 |journal=Journal of Global Economic Analysis |date=2017 |volume=2 |issue=1 |pages=1–119 |doi=10.21642/JGEA.020101AF |url=https://jgea.org/resources/jgea/ojs/index.php/jgea/issue/view/3 |accessdate=9 March 2019|doi-access=free |url-access=subscription }} but is also implemented using the GAMS suite of software.{{cite journal |last1=Lanz |first1=Bruno |last2=Rutherfod |first2=Thomas |date=2016 |title=GTAPinGAMS: Multiregional and Small Open Economy Models |url=https://jgea.org/resources/jgea/ojs/index.php/jgea/issue/view/2 |journal=Journal of Global Economic Analysis |volume=1 |issue=2 |pages=1–77 |doi=10.21642/JGEA.010201AF |archive-url=https://web.archive.org/web/20200711093410/https://www.jgea.org/resources/jgea/ojs/index.php/jgea/article/view/38 |archive-date=11 July 2020 |doi-access=free |accessdate=9 March 2019}} The center also organizes a large-scale annual conference on global economic policy modelling. The center also provides awards and recognition to members of the research community, including the Alan A. Powell Award and the GTAP Research Fellow awards.{{cite web |title=GTAP Network: Alan Powell Award |url=https://www.gtap.agecon.purdue.edu/network/award.asp |website=gtap.agecon.purdue.edu |publisher=Purdue University |accessdate=9 March 2019}}{{cite web |title=GTAP Network: Research Fellows |url=https://www.gtap.agecon.purdue.edu/network/fellow_list.asp |website=www.gtap.agecon.purdue.ed |publisher=Purdue University |accessdate=9 March 2019}}
