Most studies utilizing experimental auction mechanisms to elicit consumers’ willingness to pay are designed to avoid potential substitution or demand-curve effects that may influence bid prices. However, previous research and auction designs have not considered the potential impact on bid...

With the controversy over genetically modified (GM) foods continuing to grow, there has been a major push for mandatory labeling of GM foods by consumer advocacy and environmental groups in the United States. These groups maintain that consumers would benefit from labels. Other groups think that...

In many countries, including those in the European Union, Japan, Australia, and China, labeling is required for foods that contain genetically modified material. Other countries, including the United States, do not require mandatory labeling of GM foods. The United States, however, does allow...

Many countries require labeling for GM food products. These countries often have different levels of genetic modification that they will tolerate before a food product must be labeled as genetically modified. For example, the European Union and Australia allow up to one percent of any ingredient...

This paper assesses consumers’ acceptance of nutritionally enhanced vegetables using a series of auction experiments administered to a random sample of adult consumers. Evidence suggests that consumers are willing to pay significantly more for fresh produce with labels signaling enhanced...

Early GM traits were obtained by transferring genes across species, largely from soil bacteria. Part of the consumer resistance to them has been their transgenic nature. Recently, breakthroughs have occurred using intragenic bioengineering where genes are moved long distances within a specie,...

Consumers' willingness to pay for food products decreases when the food label indicates that a food product is produced with the aid of modern biotechnology. This bulletin presents empirical evidence on consumers' willingness to pay for biotech foods based on the presence or absence of labels...

This paper examines the market characteristics that push consumers in high income countries to resist GM foods, with an emphasis on negative information from environmental groups and third-party, verifiable information. For this study, unique data were collected from adult consumers in the...
