The Value of Verifiable Information in a Controversial Market: Evidence from Lab Auctions of Genetically Modified Food
Get PDFTwo interested parties dominate the current debate on genetically modified (GM) foods: environmental groups and agribusiness companies. For the average consumer to arrive at an informed decision on these new foods, they must rely on information from interested parties. Unfortunately, information from interested parties does not provide an accurate picture of the benefits and risks of new products. This paper examines the effects of information on consumers? demand for new food products, GM-foods, in an environment where information from one or more interested parties is provided. We design and conduct laboratory auction experiments using randomly chosen adult consumers from two large metropolitan areas who are grouped into twelve experimental units and subjected to six randomly assigned information treatments. We find that in this environment, verifiable information has a small but positive value to sample consumers, and the projected annual social value to all processed foods consumed is relatively large for this public good. Such a large potential value may make it worthwhile for the United States to establish a new third party institution that would produce and distribute verifiable information on GM food.
Who Do Consumers Trust for Information? The Case of Genetically Modified Foods
Get PDFTo be effective, groups that disseminate information need the trust of consumers. When multiple groups provide conflicting information on a new product or process like GM-foods, consumers place different levels of trust in the various sources. We present a model of the contributions of personal and social capital of a consumer, and test a multinominal logit model of relative trust in five different sources of information on genetic modification using a unique data set. Among our findings is that an increase in consumer's education lowers the probability of trusting information from government, private industry/organizations, consumer and environmental groups, or other sources relative to information from an independent, third-party source, and conservative religious affiliation reduces the odds of a consumer trusting private industry/organization and increases the odds of trusting nobody relative to an independent, third-party source.
Are U.S. Consumers Tolerant of GM Foods?
Get PDFGenetically modified (GM) foods have caused many controversies. One important controversy relates to tolerance?the impurity rate that is tolerated before a commodity must be labeled as genetically modified. Currently, the United States does not have a specific tolerance or threshold level for GM foods. This paper uses experimental auctions to determine consumers? acceptance of non-GM foods with zero, 1 percent, and 5 percent tolerance for genetically modified material. Our results indicate that consumers would pay less for food that tolerates GM material, but the discount is not significantly different for foods with 1-percent and 5-percent GM content.

The Effects of Prior Beliefs and Learning on Consumers' Acceptance of Genetically Modified Foods
Get PDFIn most environments, information is critical to consumersï¾’ decision making. Consumers have prior beliefs about quality and price of goods and services and obtain new information which is used to update these prior beliefs or to form posterior beliefs, i.e., Bayesian learning. New food products made from herbicide-tolerant and insect-resistant crops using bioengineering, have appeared in U.S. supermarkets starting in 1996. The objective of this paper is to examine in depth the role of consumerï¾’s prior beliefs about genetic modification and of diverse, new information on their willingness to pay for foods that might be genetically modified. One hypothesis is that prior beliefs matter and, second, consumers give less weight to information from interested than disinterested par ties. We use a unique data set collected from a set of economics experiments to show that consumers who had informed prior beliefs behaved as if they placed more trust in the third-party information than in information from interested parties. Participants whose prior beliefs were uninformed revealed greater variation in their bidding behavior than informed participants.
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
