Bid prices were elicited for standard-label cookies, muffins, and potato chips and those identified as not including genetically modified (GM) ingredients using an experimental auction. Including a statement that the product did not include GM ingredients increased bids over those offered for standard-label products. Providing negative-biased information about the impact of GM crops on the environment increased the risk participants associated with GM foods, and positive-biased information decreased perceived risk. Overall, providing impact information, whether positive- or negative-biased, increased bids for products presumed GM. The influence of information bias on bids varied among selected participant groups, supporting the presence of uniquely responsive market segments.
