Abstract: "The first generation of genetically modified (GM) crop varieties sought to increase farmer profitability through cost reductions or higher yields. The next generation of GM food research is focusing also on breeding for attributes of interest to consumers, beginning with golden rice, which has been genetically engineered to contain a higher level of vitamin A and thereby boost the health of unskilled laborers in developing countries. Anderson and Jackson analyze empirically the potential economic effects of adopting both types of innovation in Sub-Saharan Africa (SSA). They do so using the global economywide computable general equilibrium model known as GTAP. The results suggest that the welfare gains are potentially very large, especially from nutritionally enhanced GM wheat and rice, and that contrary to the claims of numerous interests those estimated benefits are diminished only slightly by the presence of the European Union's current barriers to imports of GM foods. In particular, if SSA countries impose bans on GM crop imports in an attempt to maintain access to EU markets for non-GM products, the loss to domestic consumers due to that protectionism boost to SSA farmers is far more than the small economic gain for these farmers from greater market access to the EU. This paper a product of the Trade Team, Development Research Group is part of a larger effort in the group to better understand the contributions of both new technologies and discriminatory trade policies to economic welfare of different groups in developing countries"--World Bank web site.
