Objective Summary

Global general equilibrium modelling is a widely accepted input into trade policy formation process in Australia. In Australia a primary database used to analyse trade policy is produced by the Global Trade Analysis Project (GTAP) at Purdue University in the United States. A new version of this database is scheduled to be released in March 2005. While the GTAP database provides a good coverage of global trade and protection, the development of the trade protection data is not sufficiently focussed on Australianspecific trade issues. This is understandable given GTAP produce a database with 87 regions. In any exercise as large as this, simplifications must be made (such as the use of dated information averaging and simple estimation techniques). However, these simplifications can result in inaccuracies that affect the representation of trade protection of critical importance from an Australian perspective. The main objective of this project is to critically review and reestimate where appropriate the agricultural protection data in the GTAP database. This will greatly enhance the capacity of Australian trade researchers to analyse the economic impacts of international agricultural trade policy and therefore better informed policy making.
