This study confirms that substantial barriers to market access will remain both rich and poor countries following full implementation of the Round agreement. The analysis finds that approximately 40% the costs of these barriers to developing countries arise from barriers to access in industrial countries and 60% from barriers in developing themselves. The results suggest that there would be large gains almost all regions from a round of negotiations that increased market in the North and South.
