Extrapolating experimental-auction results using a stated choice survey

During the last decade, experimental auctions and stated choice (SC) surveys have been widely used to study food demand. These methods have complementary strengths and weaknesses. Experimental auctions are limited by the availability of products and the use of locally recruited participants, whereas SC surveys lack real economic incentives. We use an SC survey to extrapolate the results of an experimental auction to hypothetical products with non-existing attribute combinations and to a representative sample of Norwegian consumers. The method is illustrated using Norwegian consumers' preferences for country-of-origin and hormone status for beef.
