There are a number of controversial issues that surround agricultural biotechnology and genetically modified products. International trade and policies are at the forefront of these controversies. This book addresses these issues and has been developed from a meeting of the International Consortium on Agricultural Biotechnology Research, held in Revello, Italy, in July 2004. It covers five themes: analytical studies; empirical trade studies; spillover dimensions; intellectual property rights; and applied general equilibrium trade models.
