GTAP Research: Extending the GTAP Data Base for Analysis of Climate Change

This project was funded by the United States Department of Energy and was undertaken jointly by researchers at the Global Trade Analysis Project (GTAP) of Purdue University (Thomas Hertel, Robert McDougall, Gerard Malcolm, Truong P. Truong), the University of Colorado, Boulder (Thomas Rutherford and Mustafa Babiker) and the OECD Development Centre (Jean-Marc Burniaux and Christophe Complainville). It aimed to improve the analytical basis for the development of policies relating to carbon restrictions under the Framework Convention on Climate Change. Cost-effectiveness analysis demands some attention to the question of 'leakage' - how much are the restrictions on Annex I countries likely to be diluted by shifting patterns of trade and production.

In addition, questions of international competitiveness have surfaced. Past studies of this problem suffered from severe data limitations.

The goal of this project was to construct a publicly available data base which contains the necessary combination of, The approach involved collection of consistent data on energy quantity flows, prices and taxes, thereupon incorporating them into the GTAP Data Base.

A special purpose data base, known as GTAP 4-E, has been constructed, which contains information on energy quantities. In addition, these new energy data will be incorporated into the publicly-released version 5 GTAP Data Base. These products allow researchers analyzing the trade, production and welfare consequences of international carbon restrictions to provide more reliable assessments of the national costs and benefits of these policies.

Background Information
Contribution of additional price/tax information
To see where gaps in the price/tax database exist, view the price documentation and data. In particular, more data for the former Soviet Union and Eastern Europe and data on energy taxes would be very useful.

If you have ideas or information on new data sources, please contact Robert McDougall.
