GTAP Data Bases: GTAP 8 Data Base

What is the GTAP 8 Data Base?
The centerpiece of the Global Trade Analysis Project is the GTAP Data Base, a fully documented, publicly available global data base which contains complete bilateral trade information, transport and protection linkages. The GTAP Data Base is utilized by thousands worldwide and is a key input into contemporary applied general equilibrium analysis of global economic issues. The current release, the GTAP 8 Data Base, boasts dual reference years of 2004 and 2007 as well as 129 regions for all 57 GTAP commodities.

The GTAP Data Base is most commonly used with the GTAP Model and RunGTAP software. First, the user must aggregate the data (regions, commodities and endowments) using the GTAPAgg (or FlexAgg) program provided with the data base to the desired level and then use with the GTAP or GTAPinGams model/s to analyze the impact of global policies (trade, environmental, migration policies are commonly examined). Alternatively a user may be interested in extracting country SAMs or I-O tables from the GTAP Data Base for single country models. If you are interested in these alternative uses of the GTAP Data Base, we suggest you read through the points detailed on this page about what GTAP Data Base is not.

How GTAP Network members are using the GTAP 8 Data Base
United Nations Economic Commission for Africa (ECA)
Sub-regional Office for Eastern Africa (SRO-EA)
Kigali, Rwanda

African governments have embraced regional integration as a strategy to accelerate economic development and reduce poverty. The primary goal of regional integration through Preferential Trade Agreements (PTA's) is to promote trade and deeper integration by reducing trade barriers and increasing market access to member countries. The proposed Free Trade Area between the Common Market for Eastern and Southern Africa (COMESA), the South African Development Community (SADC) and East African Community (EAC), has the main objective of strengthening and deepening economic integration in the southern and eastern Africa region. The COMESEA-SADC-EAC free trade area would include 26 African countries (more than half of the countries in Africa) with 57% of the population of the African Union. The free trade area is therefore considered an important milestone in the economic integration of the African continent.

In Economic Effect of the proposed COMESA-SADC-EAC Free Trade Area on Eastern Africa, we will use the GTAP (Global Trade Analysis Project) CGE model and database (8.0 version) to measure the effects of the proposed COMESA-SADC-EAC Free trade area on welfare, trade flows, prices, consumption and production in the region.

Associate Professor Jayatilleke S Bandara has been a member of the GTAP Network since 1997 and contributed to the GTAP 4 Data Base while he was at GTAP for four months on his sabbatical leave. He was instrumental in incorporating Vietnam, South Africa and Sri Lanka, for the first time, into GTAP 4. He has since been a regular contributor of the Sri Lankan I-O table to the GTAP Data Base. While contributing, he has used the GTAP Model and the data base to address various trade policy issues related to South Asia. His GTAP-related work has been published as book chapters and journal articles. He has also been a regular participant of the annual GTAP conference. Currently he is using the GTAP 8 Data Base to implement both static and dynamic GTAP models in order to analyse trade and food security related issues in South Asia. As a CGE modeller, he strongly believes that the GTAP 8 Data Base is extremely useful to address a wide-range of global issues such as trade, regional integration and climate change.

Kunming, China

As the foreign direct investment enters china in forms of setting up new enterprises, this research tends to apply the computable general equilibrium method to analyse its effects on the whole economy, factor market, product market, foreign market, and social welfare, etc., under the assumptions of perfect and imperfect competition, instead that former literatures focus more with the FDI inflow data on the technology spillover, export effect and economy boost under the econometrical method which turns to be relatively disconnected the link with the rest parts of the economy.

I utilized the past GTAP Data Bases and model for measuring impacts of international trade and freight transport policies as well as forecasting future amount of international trade and cargo, by combining with our originally developed model for predicting worldwide international cargo flow. As for the latest version, GTAP 8 Data Base, I'm also using it for renewing our estimation results on the future trade and logistics worldwide as well as those in several regions of the world. In particular, since I'm now engaged in several projects to support developing countries in North Africa (e.g. Egypt) and Southeast Asia (e.g. Myanmar) from the viewpoint of international logistics and infrastructure planning, the GTAP Data Base essentially needs when estimating future amount of international trade and cargo as well as measuring impacts of international trade and logistics policy including infrastructure investment in these regions.

Armidale, Australia

I have used previous versions of GTAP Data Base to analyse trade policy issues of Australia, Japan, South Asia and China and the extended regional coverage of the GTAP 8 Data Base will facilitate further my research in this area. I have just received an Australian Research Council (ARC) Linkage grant for next four years and there are 6 researchers in my team. The AGL Energy Ltd is our linkage partner. Our aim is to develop a multi-regional CGE model for Australia which is capable of analysing the responses of energy users (consumers) and energy suppliers (producers) to the carbon tax in Australia, especially at regional level. As an extension to our work, we plan to use the GTAP 8 Data Base and GTAT-E to link our national model to the world model. In doing so, we plan to generate our modelling capacity to analyse the impact of government's proposed policy of linking Australian carbon price to the EU's emissions trading scheme.

I am a Senior Research Economist at the Central Bank of Venezuela. My area of interest lies in the applied optimization methods. Sectorial analysis is part of my job along with other issues regarding international macroeconomics. The GTAP Data Base and the computable general equilibrium models (both the static-comparative and the recursive) are applied in my research about factual and counter-factual analysis of trade policy and tax incidence. For instance, currently I am working on the sectorial impacts and macroeconomic risks relative to Venezuela's accession to MERCOSUR. I have been part of the GTAP Network since 2003 and, at the present time, I am a data contributor in representation of the Central Bank of Venezuela.

I am a development economist with interest in exploring the issues of growth and development in the context of the economies already integrated into global trade and those pursuing their efforts to catch up with the forces of globalization. My research emphasizes on the issues of growth and technological change and its spillover; trade, international economic integration; human capital, skill acquisition and technology adoption. I am also interested in diversifying in the area of export sophistication, fragmentation, and migration issues. I follow economy-wide impact analysis of these issues employing global CGE GTAP Model. Being a user since my Doctoral studies at Monash University and a GTAP Data Base subscriber since 2002, I find GTAP 8 extremely useful for furthering my work in the area of trade, technology and migration. Most of my publications are based on different versions of the GTAP Data Base and augmented GTAP Model.

The research area "The Environment and Natural Resources" uses the GTAP Data Base to calibrate its multi-regional, multi-sectoral, recursive dynamic CGE model DART that is designed and used for the analysis of international climate policy and related issues. We have just finished work on the strategic incentives for higher than "fair" border carbon adjustments and are in the process of analyzing the implications of different Post-Kyoto climate policy scenarios for China and India within a larger set of soft-linked models. There is special focus on land-use and bioenergy and DART is currently coupled to a physical model of biomass growth in order to derive medium term scenarios for land-use dynamics. The GTAP 8 Data Base with its extended coverage of regions will be especially helpful for our project to analyze the economic impacts of the DESERTEC project for Europe and the MENA region.

I use the GTAP Data Base for a variety of investigations including trade liberalisation and agricultural development policies in sub-Sahara African countries. I have found the data base to be useful as single country models are not available for many of the countries in which I am interested. I am currently working with the Land Use and Land Cover Data Base to analyse possible climate change mitigation policies.

The paper I have been using the GTAP 8 Data Base for is called "Trade Wars and Trade Talks with Data".

How large are optimal tariffs? What tariffs would prevail in a worldwide trade war? How costly would be a breakdown of international trade policy cooperation? And what is the scope for future multilateral trade negotiations? I address these and other questions using a unified framework which nests traditional, new trade, and political economy motives for protection. I find that optimal tariffs average 59 percent, world trade war tariffs average 58 percent, the welfare losses from a breakdown of international trade policy cooperation average 2.4 percent, and the possible welfare gains from future multilateral trade negotiations average 0.5 percent.

I am analysing the effects of regional integration in South Asia with the GTAP 8 Data Base. To my knowledge, there is no alternative to the GTAP Data Base if someone is willing to embark on a project that require an equilibrium database that is global in nature. The extension of the data base to implement dynamic version of the GTAP Model has been particularly useful for me.

I use the GTAP 8 Data Base to evaluate the textile and apparel (T&A) sectoral impact of various newly-reached or negotiated free trade agreements. For example, in my recent studies, I finds that the Transpacific Partnership Agreement (TPP) might lead to a fundamental shift in the pattern of T&A trade within the Pacific Rim, creating both winners and losers. According to the findings, such a result would be caused jointly by the trade creation and trade diversion effect of the TPP as well as the T&A-specific regional production and trade network (RPTN) in the Asia-Pacific region.

We are using the GTAP 8 Land Use and Land Cover Data Base to provide inputs into a land-use-change (LUC) model, called BioLUC, that uses a system-dynamics approach. The BioLUC model takes aggregated data from the GTAP data base (and other resources) such as yields and production area and then through a stock and flow system dynamically tracks how land use changes overtime to meet future demand scenarios. Existing more detailed models are typically not intended to easily and quickly run multiple alternative scenarios or switch easily between datasets. BioLUC is intended to complement existing LUC modeling approaches by being a tool to more easily testing assumptions and examine possible trends in future LUC.

Recently a research work on 'Economy wide Impacts of Comprehensive Economic Partnership Agreement between India and Canada at 2030' led by me as a principal investigator in collaboration with the Department of Economics, Jadavpur University, Calcutta, India under the 'Shastri Pro Development Initiative Grant' of Shastri Indo-Canadian Institute, Calgary, Canada has used GTAP 8 Database extensively. The GTAP 8 Data base and model played a central role in assessing the possible long term economic and environmental impacts of a Comprehensive Economic Partnership Agreement (CEPA) between India and Canada. Adopting a CEPA will greatly enhance bilateral trade between the two nations despite having a small positive impact on output and marginal environmental cost.

So far I have used the GTAP data in three different ways:
  • I teach two courses, one on international trade theory, the second one on trade policy analysis. In these courses I am using GTAP to demonstrate how GE models work.
  • I am using GTAP to extract some of the data which I need for research work on effects of exchange rate misalignments.
  • I tried to use GTAP for (cautious) estimates of effects of proposed trade liberalization (TTIP) on the Czech Republic.

I am Professor at the Department of Economics and Director of the Centre for Jawaharlal Nehru Studies, Jamia Millia Islamia, New Delhi. I have also served as Senior Economist and Economist at the United Nations Conference on Trade and Development (UNCTAD), India Programme, New Delhi. While working at UNCTAD, I have used the GTAP 6 and 7 Data Bases for analysing various trade policy issues such as Assessment of Green Box Subsidies, Quantification of Benefits from Economic Cooperation in South Asia, India-EU FTA, India-ASEAN FTA and on many other Indian regional and multilateral trade integration initiatives. I have also worked on India-Korea CEPA, India-Australia FTA and India-Japan CEPA using GTAP Model and data bases. I have published 7 research papers using GTAP (Model and Database) in refereed international and national journals of repute. I intend to use GTAP 8 Data Base to assess the effects of Indian regional trade agreements, trade-environment linkages, fiscal deficits and economic growth and patterns of energy uses in India under the assumptions of perfectly competitive and imperfectly competitive market conditions.

My research interests are in trade and regional integration with a focus in the East Asia region. I use the GTAP Data Base and CGE simulations extensively in my research work that looks into potential economic effects of various FTA scenarios on members and non-member economies as well as likely effects of liberalising individual sectors or sub-sectors of individual economies. The GTAP Data Base is also very useful for me to investigate industries linkages across countries, vertical integrations, and global production chains.
