2. Technische Universität München Introduction 2 Rapeseeds -Usage: animal feed, human consumption, industrial production, biofuel -Main producer: Europe, North America, China, India and Australia -GM HT rapeseed cultivated in Canada, U.S., Australia and Chile - 24% of the global annual rapeseed production in 2013 (James, 2013) -Farmers in the EU cannot experience possible benefits from cultivating GM HT rapeseeds  socio-economic ex ante assessment of GM HT rapeseeds in Germany

7. Technische Universität München Theoretical model and methods 7 Option value - The option to deregulate has a value itself as it gives a possibility to reduce social losses by postponing the action.

8. Technische Universität München Data -Benefits from GM HT rapeseed: 10% yield increase (Brookes & Barfoot (2012)), no-till -Time series for the incremental, achievable gross margins per hectare with respect to rapeseed cultivation in Germany for the period 2007–2013 for a situation in which GM HT rapeseed cultivation had been adopted. -We compare conventional rapeseed cultivation incorporating ploughing to that using a no- till cultivation system. -Adoption process similar to the adoption of hybrid rapeseeds by German farmers -The differences in CO 2 emissions between conventional and no-till cultivation are, on average, 89 CO 2 equivalent/kg rapeseed (IFEU, 2014). -CO 2 evaluated with €65.18/tonne of carbon (Tol, 2011) 8 Main assumptions

Technische Universität München Results and discussion SocietyPer citizenPer household Per hectare rapeseed MISTICs for 2013 (for infinite time horizon) in € 1,135,317,340 14.0528.141014.62 Possible forgone benefits in 2013 in € 416,026,684 5.1710.31 242.58 9 Monetary effect GM HT rapeseed cultivation in Germany Note: Maximum incremental social tolerable irreversible cost (MISTICs) are calculated for German society comprising a population of 80.5 million citizen (DESTATIS, 2014d), 40.34 million households (EUROSTAT, 2014) and a total rapeseed cultivation area of 1.47 million hectares. To calculate a value per hectare rapeseeds we assume that rapeseed cultivation on the same field is only possible every third year.

10. Technische Universität München Conclusion The low MISTICs value of GM HT rapeseeds for consumers (€14.10) in combination with consumer’s current generally negative attitude towards GMOs (European Commission, 2010) indicates a low political probability for the approval of GM HT rapeseeds in the short term. Regarding MISTICs, we only calculated a threshold value. The remaining question is whether the actual incremental irreversible costs will exceed the MISTICs. 10 Introducing GM HT rapeseeds in Germany
