Unter welchen Umständen würden deutsche Landwirte gentechnisch veränderten Raps anbauen? Ein Discrete-Choice-Experiment 31
Breustedt, Gunnar; Muller-Scheessel, Jorg; Meyer-Schatz, Henrika Marie.
We examine the factors affecting the willingness of German farmers to adopt genetically modified (GM) oilseed rape after the pending commercial release of GM varieties. The analysis is based mainly on a web-based Discrete Choice Experiment with 217 oilseed rape growers in Germany. The determinants of adoption were estimated with the use of a multinomial probit model. Results indicate a significant impact of economic determinants on the adoption willingness: the difference in gross margins between GM and conventional rape, the probability and level of liability for damage caused by cross-pollination, and the length of the waiting period before a farmer can return to conventional rape are all highly significant. Among the farm characteristics, farm size...

Forecasting the Adoption of GM Oilseed Rape: Evidence from a Discrete Choice Experiment 31
Breustedt, Gunnar; Muller-Scheessel, Jorg; Latacz-Lohmann, Uwe.
This paper explores farmers’ willingness to adopt genetically modified oilseed rape prior to its commercial release and estimates the ‘demand’ for the new technology. The analysis is based upon choice experiments with 202 German arable farmers. A multinomial probit estimation revealed that GM attributes such as gross margin, expected liability from cross pollination, or flexibility in returning to conventional oilseed rape significantly affect the likelihood of adoption. Neighbouring farmers’ attitudes towards GM cropping and a number of farmer and farm characteristics were also found to be significant determinants of prospective adoption. Demand simulations suggest that adoption rates are very sensitive to the profit difference between GM and non-GM rape...

UNTER WELCHEN UMSTANDEN WURDEN DEUTSCHE LANDWIRTE GENTECHNISCH VERANDERTEN RAPS ANBAUEN? EIN DISCRETE CHOICE EXPERIMENT (German) 31
Breustedt, Gunnar; Muller-Scheessel, Jorg; Meyer-Schatz, Henrika Marie.
Mittels eines Discrete Choice Experimentes werden empirisch Determinanten identifiziert, die die Entscheidung für den potenziellen Anbau von gentechnisch verändertem Raps durch 217 rapsanbauende Landwirte bestimmen. Die Deckungsbeitragsdifferenz gegenüber konventionellem Raps, die Haftungswahrscheinlichkeit und –höhe für Auskreuzungsschäden, die Wartezeit für die Rückkehr zu konventionellem Rapsanbau, die Einstellung von Nachbarlandwirten gegenüber Grüner Gentechnik, die Betriebsgröße, der betriebliche Rapsanteil, der Betriebstyp, die Innovationsneigung des Betriebsleiters, das Geschlecht des Betriebsleiters, eine akademische Ausbildung und die Existenz von Kindern unter 16 Jahren werden als signifikante Einflussgrößen identifiziert. Folglich ist neben den...
