Modelling the global market effects of GMOs: The importance of preferences and policy choices

The debate about the use of genetically modified organisms (GMOs) in agricultural production continues to be very polarised. Proponents contend that this new biotechnology promises increased productivity, better use of natural resources and more nutritious foods. Opponents are concerned about potentially adverse implications for the environment and food safety. This paper illustrates how the use of empirical models of the global economy may inform the debate by examining what the effects of widespread adoption of genetically modified crop varieties in some (non-European) countries might be in light of different policy and consumer preference responses in Western Europe and High-Income Asia
