Conjoint analysis is used to elicit consumer preferences for attributes of genetically modified foods. Market segments are identified based on a cluster analysis of respondents' preferences for brand, price, and GMO content. A logit analysis is used to analyze consumer characteristics associated with the acceptance of GMO foods. Those consumers who were most risk averse, most likely to believe that GMOs improved the quality or safety of food, and most knowledgeable about biotechnology were the most likely to be accepting of GMO foods. These findings are used to develop implications for producers and regulators of GMO foods.
