Keine Chance für genetisch veränderte Lebensmittel in Deutschland? Eine experimentelle Analyse von Zahlungsbereitschaften

In this paper we use laboratory experiments to investigate (i) consumer acceptance of genetically modified (GM) foods in Germany, (ii) the effect of neutral information on consumer acceptance, and (iii) the existence and the extent of a hypothetical bias. Participants in our sample generally preferred non-GM over GM products and discounted GM food products by around 50 %. We do not find significant impacts of neutral information on consumer valuation of GM food products. We show the existence of a hypothetical bias finding a significant upward bias in the valuations elicited in a hypothetical scenario.
