International diffusion of gains from biotechnology and the European Union's Common Agricultural Policy
研究了欧盟在共同农业政策下采用或拒绝转基因作物对经济福利的影响，发现拒绝转基因作物会损失大量福利，但政策保护了农民收入。
This paper analyses the impact of adopting or rejecting genetically modified (GM) crops in the European Union, taking into account the EU Common Agricultural Policy (CAP). In this paper the productivity impact of genetically modified organisms (GMOs) differs across crops, taking factor biased technology change into account. The transfer of knowledge across countries is modelled as a process of endogenous knowledge spill-overs. Analysis with a multi-region applied general equilibrium model shows that the CAP protects farm income and production despite non-adoption of the more productive GM crops in the EU. The EU will forgo substantial benefits in terms of economic welfare if it bans GM imports. (C) 2004 Elsevier B.V. All rights reserved.
