Journal of Global Economic Analysis
The Center for Global Trade Analysis is extremely pleased to introduce the inaugural issue of the Journal of Global Economic Analysis. This new journal (https://jgea.org/) provides an open access, peer-reviewed platform for publication and dissemination of innovations in modeling, data, software and teaching for applied general equilibrium analysis.
This first issue features two important new papers - and associated modeling software -- for implementing Melitz-style firm heterogeneity into AGE models. It also includes two papers on data base developments: the GTAP 9 Data Base and the GTAP-Power Data Base. Finally, it includes a paper documenting software for accessing, manipulating and presentation the World Bank's WDI data base.
GTAPAgg2 and GTAP9a, are now available!
GTAPAgg2 is an updated version of the GTAPAgg software package developed by Mark Horridge at the Centre of Policy Studies. Nearly all applications of the GTAP Model use an aggregation of the fully disaggregated GTAP Data Base. The software helps you prepare an aggregation scheme, then uses your scheme to prepare an aggregated data base for the GTAP Model. The GTAPAgg2 program has been redesigned to handle multiple GTAP Data Bases.
GTAP 9 has also has been updated to version 9a. Included in this release:
GTAP 9 Satellite Data and Utilities
The GTAP Center is pleased to announce that we have released four more satellite data and utilities, the following are free of charge and have been updated for use with the GTAP 9 Data Base.
GDyn Data Base: The GDyn Data Base facilitates development of baseline projections consistent with the GTAP 9 Data Base and for direct use with the GDyn Model.
GMig2 Data Base: The GMig2 Data Base contains global bilateral migration and remittances data consistent with the GTAP 9 Data Base.
GTAP-E Data Base: The GTAP-E Data Base provides carbon dioxide (CO2) emissions data distinguished by fuel and by user for each of the 140 countries/regions in the GTAP 9 Data Base.
GTAP Non-CO2 Emissions Data Base: The GTAP Non-CO2 Data Base complements the GTAP-E Data Base and provides information on other greenhouse gas (GHG) emissions such as Methane (CH4), Nitrous Oxide (N2O), Fluorinated gas (FGAS).
How GTAP Network members are using the GTAP 9 Data Base
Professor, Hanyang University
I have used the GTAP Data Base (along with other supplementary ones) for my research works since my PhD days. I am a regular subscriber of the GTAP Data Base and satellite programs as well. My area of research is related to globalization, trade, and economic development. For exploring multi-faceted issues related to global trade and development GTAP Data Base is excellent resource to use and the current version 9 is expanded to include more aspects. Over the years, the expanded versions of GTAP has benefited me for exploring issues such as technology transfer, skilled-unskilled wage gap, trade integration, and allied topics. Right now, I will use GTAP 9 for studying issues related to firm heterogeneity, mega trade deals which is my current research interests. Also, I published a book in 2014 which included contributions from reputed CGE scholars using GTAP and other CGE models like MONASH or USAGE. No doubt, GTAP 9 and other databases are useful research materials for state-of-the art areas.
Deputy Chief Executive, New Zealand Institute of Economic Research
John and his colleagues at NZIER are using the GTAP 9 Data Base primarily for evaluating the potential effects of New Zealand's current and proposed Free Trade Agreements, such as TPP and the EU-NZ FTA. They are also linking the GTAP Model with their more detailed single-country CGE model of the New Zealand economy - ORANI-G-NZ - to assess the impacts of trade liberalisation at a more detailed industry and sectoral level.

The use of GTAP in my research program has been fitting these data to endogenous saving – multi sector growth models. Most recent applications deal with: economic growth and ground water dynamics in the Punjab of India, strengthening ecosystem and development linkages in the Republic of Kazakhstan, the conjunctive use of irrigation water over time in Morocco, land market integration and structural change in Zambia, a journal paper on international trade, exhaustible resource abundance and economic growth, and a thesis on the effect of transnational farmland investments over time on the Ghanaian economy. The data were also used in the book: Multisector Growth Models: Theory and Application, Springer pub. 2010. Additionally, the data is also used in my MS and Ph.D. level classes.
Assistant Professor, School of Environmental Science, The University of Shiga Prefecture
I am using the GTAP 9 Data Base for developing a CGE model for analyzing climate change issues. I use the data base, but develop my own dynamic CGE model. One of my recent interests is to link climate science and climate economic studies.
Assistant Professor, Department of Civil and Environmental Engineering, University of Waterloo
Using the GTAP Data Base, Dr. Bachmann is studying the impact of the Canada Korea Free Trade Agreement and the Comprehensive Economic and Trade Agreement (CETA) on Canada’s transportation system. He is currently quantifying the impact of these trade agreements on Canada’s trade flows in terms of the resulting interprovincial and international trade flows, measured by volumes and indicated by commodity group, compared to the pre-trade agreement state of trade flows. These projects are supported by Transport Canada and Industry Canada. Chris Bachmann is an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Waterloo in Waterloo, Canada.

I began to learning the GTAP Model in 2002 and used it intensively afterward. More than 50 academic research papers and reports had been published up to now by adopting standard or improved GTAP Model. Meanwhile, I have developed China's agricultural partial equilibrium model and have been trying to develop China's dynamic national and regional (provincial level) CGE models.
Director of Industrial Analysis Division; Associate Professor, Shanghai WTO Affairs Consultation Center
My job is to analyze the modern and potential trade policies and provide policy facts and suggestions to government. Parts of my responsibilities are quantifying the impact of trade policy on the economy based some quantifying and empirical instruments, for example GTAP Model and other general or partial equilibrium models as well as some econometrical models. GTAP 9 Data Base is the most comprehensive database including enough economies and sectors, being the strong backing for lots of our analysis.
Lecturer, University of Loyola
I am interested in trade analysis worldwide and more specifically in Eastern Europe (Ukraine, Russia, and the EU) and Central American countries. Furthermore such issues as tariff and non-tariff barriers to trade on agricultural goods and its modeling are in scope of my interest. Lastly, tax-subsidy policies and its modeling in GTAP frame (as an example EU Common Agricultural Policy).
Head of Economic Modeling at the Centre for Global Trade and Investment, São Paulo School of Economics - Getulio Vargas Foundation
I have been using the GTAP 9 Data Base to better understand the interplay between Preferential Trade Agreements and the formation of Global/Regional Value Chains, taking into account the role of non tariff barriers such as TBT, SPS and trade facilitation. This is, nowadays, a crucial issue for less integrated economies such as Brazil.
Energy Analysis Team, Sustainable Systems and Social Sciences Group, Oak Ridge National Laboratory
Uses the GTAP framework to implement and simulate CGE models for applied energy-environmental policy analysis. Static and dynamic CGE models are used to assess the impacts of U.S. biofuel policy on land use change, greenhouse gases emission, and the economy. Others applications include dynamic evaluations of the comparative implications of demand vs. supply shocks on global and regional economies.
PhD Student, University of Arkansas
I am interested in modeling renewable energy adoption in Saudi Arabia. My plans to use a combination of GTAP modeling and life cycle assessment (LCA). The LCA's analysis will be extended to include changes in economy and technology through using the Computable general equilibrium (CGE) in GTAP framework in order to include the indirect environmental consequences caused by the RE adoption.
Research Fellow, Inst of Econ, Academia Sinica
The GTAP Model and Data Base has been used by our GEMTEE(General Equilibrium Model for Taiwan Economy and Environment) team in Academia Sinica to investigate the macroeconomic and sectoral impacts of Taiwan’s population dynamics and policies related to sustainable development and free trade agreements with New Zealand, Singapore and China. Recently, policy debates upon whether Taiwan should join TPP and RCEP are mostly based on GTAP simulations.
Researcher, Academy of State Administration of Grain
I am engaged in the Chinese grain supply and demand analysis trying to establish a partial equlibrium model using lots of unique data. GTAP is a very effective and important tool kit to support this global analysis.
Researcher, Norwegian University of Science and Technology
Richard Wood works with the GTAP Data Base in analysing environmental impacts associated with trade and final demand. Taking a “consumption based” approach, Richard looks at the interconnection between development, trade and the environment, in order to determine underlying drivers of our impacts. Richard is involved in database development of multi-regional input-output (MRIO) models, and in this context uses the GTAP Data Base alongside other MRIO databases to understand robustness and variability across the databases (see www.environmentalfootprints.org).
Ph.D. Research Fellow, Indian Institute of Technology Kanpur
The topic of my Ph.D. dissertation is the evaluation of proposed Regional Comprehensive Economic Partnership (RCEP) agreement between 16 Asia-Pacific countries using general equilibrium framework. For this purpose, I am using the Static GTAP Model and the GTAP 9 Data Base is the only database which provides the latest, detailed and consistent data to estimate it. The main objective of my research is to evaluate the impact of reduction in trade barriers due to RCEP agreement on economies of member and non-member countries. The usage of the GTAP Model with the GTAP 9 Data Base allows me to report the direct and indirect effects of reducing trade barriers in a post-simulation environment.
Professor, Kobe Gakuin University
I have studied the impacts of trade policy and climate change policy by using the GTAP Data Base and Model under several research projects. In particular, I am interested in the structural change caused by the policy and analyzing it by combining a CGE approach with an input-output approach. I intend to use the GTAP 9 Data Base and GDyn-E Model to investigate the economic and environmental effects of East Asian emission trading in the context of China’s 2030 carbon peak out.

Pantelis CAPROS is Professor of Energy Economics at NTUA (National Technical University of Athens). Over 25 years, he is leading research based on large-scale numerical models, which simulate energy markets, project energy investment into the future, optimize roadmaps for climate change mitigation and assess economic and societal impacts. He is the Director of E3MLab, a laboratory operating within the NTUA that specializes in the construction and use of large scale computerized models covering the areas of Energy, the Economy and the Environment. Such models are used to make projections and analyze complex issues requiring system-wide consideration. The European Commission, Governments, electricity and gas companies, and their associations, are widely using these models, namely PRIMES and GEM-E3, in their policy analysis, continuously over the last 20 years. Electricity and Gas market design, long-term energy/environment planning and macroeconomic analysis are the main topics of Prof. Capros's consultancy activities. Mathematical programming, mathematical economics and energy analysis are the scientific disciplines of Prof. Capros's teaching and publishing activities.

For me, the GTAP 9 Data Base is an essential source of data for a number of different lines of research on trade policy and regional integration. Our work at CEFIR is particularly focused on the countries of the Eurasian Economic Union (EAEU): Armenia, Belarus, Kazakhstan, Kyrgyzstan and Russia. The GTAP 9 Data Base is unique since it contains social accounting matrices for all five EAEU countries. This is why the GTAP 9 Data Base is the cornerstone of most CGE-type analysis produced by CEFIR, for example, a recent assessment of reduction of non-tariff barriers in the EAEU. We also use GTAP 9 as a source of input-output tables for assessment of trade in value-added and estimation of effective rates of protection for the EAEU countries.
Full Professor, Federal University of Juiz de Fora
I am using the GTAP framework to assess the systemic effects of increased economic relations between Brazil and the countries of the America Continent. To this end, we build scenarios such as: a) the formation of a new Free Trade Area of the Americas, namely, the elimination of import tariffs and export subsidies and production among the members; b) assessment of agreements such as the Pacific Alliance and Mercosur; and c) evaluation of NAFTA agreements - Mercosur, among others. We expected to bring answers on the trade integration of the Brazilian economy with other American countries.
