Call for Associate Editors

Co-editors Thomas Hertel and Niven Winchester plan to appoint two (2) Associate Editors (AEs) for the Journal of Global Economic Analysis(JGEA). The AEs will assist with day-to-day operations and help develop and promote the journal. Day-to-day duties include sourcing expert reviewers for submitted manuscripts, evaluating submissions, and advising authors on how to improve their papers. Development activities include ensuring that the journal is visible in key citation indexes and journal rankings, refining submission management procedures, and working with Center for Global Trade Analysis staff to offer online seminars featuring JGEA papers. The AE positions are unpaid appointments for a period of three (3) years, renewable for one additional term upon mutual agreement.

How to Apply Individuals wishing to apply for an AE position should submit their curriculum vitae, along with a cover letter stating why they are suited to the position by September 15, 2020. Applications should be submitted to via email to Holly McIntire (

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.
