Assessing economic effects: co-existence of genetically modified maize in agriculture in France and Germany

摘要

Regulations on genetically modified organisms in the EU require the implementation of co-existence systems in agriculture. This paper examines the economic effects and costs for farmers when introducing different co-existence measures in genetically modified maize. For this purpose different scientific methods are used including simulation methodology. First, the co-existence costs in maize crop and seed production for individual farmers are analysed in a region in France. Second, the focus is on the regional dimension of co-existence measures when analysing the costs of buffer zones in maize production in France and Germany. Some general conclusions are then drawn.
