ARE U.S. CONSUMERS TOLERANT OF GM FOODS? AgEcon
Rousu, Matthew C.; Huffman, Wallace E.; Shogren, Jason F.; Tegene, Abebayehu.
Genetically 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.

ARE US CONSUMERS TOLERANT OF GM FOODS? AgEcon
Rousu, Matthew C.; Huffman, Wallace E.; Shogren, Jason F.; Tegene, Abebayehu.
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 in a food product to be GM before the product must be labeled as genetically modified. Japan allows 5% of any ingredient to be genetically modified before the product must be labeled as such. The United States currently does not require mandatory labeling of GM labeled foods and has no standards for what percentage of an ingredient in a food product can be genetically modified for the product to still be labeled non-GM. For the official "organic"...

BETTER DEAD THAN GM-FED? INFORMATION AND THE EFFECTS OF CONSUMERS' RESISTANCE TO GM-FOODS IN HIGH-INCOME COUNTRIES AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
This paper addressed the puzzling resistance of Presidents of southern African countries to food aid in 2002, given near certain starvation and long-term negative health effects of malnutrition of their constituents. First, I show that NGOs led by Greenpeace and Friends of the Earth are disseminating information claiming that GM foods are dangerous to human health and are "Frankenfoods." Second, people in European Union countries, who are not in any danger of starvation, have strong preferences for non-GM foods, which they can easily afford. Over the long term, however, the tastes of EU consumers matter to southern African countries because some of these countries hope to export agricultural products in the future. GM-food aid, which most likely would...

Choosing a Cigarette Brand: Determining the Value of Countermarketing Information to Smokers Using Field Auctions AgEcon
Rousu, Matthew C.; Nonnemaker, James; Farrelly, Matthew.
Information about cigarettes can help smokers come to an informed decision about what cigarettes to purchase. Countermarketing information can help smokers make informed decisions, but little is known about the value of this information to smokers. In this article, we use data from experimental auctions to estimate the value of countermarketing information that counters industry claims about reduced-risk cigarettes. We find that this information has significant value to smokers who have been exposed to marketing information from tobacco companies touting reduced-risk cigarettes, but we find no evidence it provides value to smokers not exposed to this marketing information.

Consumer Willingness to Pay for Genetically Modified Food Labels in a Market with Diverse Information: Evidence from Experimental Auctions AgEcon
Huffman, Wallace E.; Shogren, Jason F.; Rousu, Matthew C.; Tegene, Abebayehu.
With the continuing controversy over genetically modified (GM) foods, some groups advocate mandatory labeling of these products, while other groups oppose labeling. An important issue is how GM labels affect consumers' willingness to pay for these food products in the market. Using a statistically based economics experiment with adult consumers as subjects, we examine how willingness to pay changes for three food products--vegetable oil, tortilla chips, and potatoes--when GM labels are introduced. Participants in the experiments discounted GM-labeled foods by approximately 14% relative to their standard-labeled counterparts. The evidence also showed that sequencing of food labels affects willingness to pay, and that randomizing treatments is an important...

Consumer Willingness to Pay for "Second-Generation" Genetically Engineered Products and the Role of Marketing Information AgEcon
Rousu, Matthew C.; Monchuk, Daniel C.; Shogren, Jason F.; Kosa, Katherine M..
Environmental and consumer groups have called for mandatory labeling of genetically engineered (GE) food products in the United States, stating that consumers have the “right to know.” Herein, we use a nonhypothetical field experiment to examine the willingness to pay for GE-labeled products, using the only second-generation GE product currently on the U.S. market-GE cigarettes. Our results suggest consumers pay less for GE-labeled cigarettes when marketing information is absent. But, when presented with marketing information on the attributes of the cigarette, we find no evidence that consumers pay less for GE-labeled cigarettes.

CONSUMERS' RESISTANCE TO GENETICALLY MODIFIED FOODS IN HIGH INCOME COUNTRIES: THE ROLE OF INFORMATION IN AN UNCERTAIN ENVIRONMENT AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
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 United States who participated in laboratory auctions of three food types with randomly assigned labeling and information treatments. Using U.S. consumers is important because U.S. consumers are generally supportive of GM foods and free from the BSE "food scare" fears and bias towards "natural" that are hypothesized to lead Europeans to reject GM foods. Key findings are that negative GM-product information supplied by environmental groups pushes some consumers out of...

Demand Curve Effects in Experimental Auctions: The Effect of Quantity Already Owned AgEcon
Colson, Gregory; Huffman, Wallace E.; Rousu, Matthew C..
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 prices of commodity inventories held by auction participants that were obtained through transactions outside of the auction. This omission may present a problem for interpreting and analyzing auction data. Using bids from a random nth-price auction of fresh vegetables conducted in a laboratory style setting, we test whether participants’ outside inventories affect bidding behavior. We find that bidders do in fact consider their inventories, resulting in lower bid...

Demand Curve Shifts in Multi-Unit Auctions: Evidence from a Laboratory Experiment AgEcon
Rousu, Matthew C.; Beach, Robert H.; Corrigan, Jay R..
Basic economic theory predicts that a consumer's willingness to pay for a good is affected by the presence of complements and substitutes. In an auction setting, this theory implies that the presence of complements would increase bid prices for a good, while the presence of substitutes would decrease bid prices for a good. However, several experimental auction studies have sold complementary or substitutable products without regard for the effects these actions could have on bidding behavior. Using data from an experimental auction specifically designed to test the effect of complements and substitutes on bids, we used both unconditional tests and conditional tests where we derived demand flexibilities to analyze whether selling complementary and...

DESIGNING EXPERIMENTAL AUCTIONS FOR MARKETING RESEARCH: EFFECT OF VALUES, DISTRIBUTIONS, AND MECHANISMS ON INCENTIVES FOR TRUTHFUL BIDDING AgEcon
Lusk, Jayson L.; Alexander, Corinne E.; Rousu, Matthew C..
Accurately estimating consumer demand for new products is an arduous task made even more difficult by the fact that individuals tend to overstate the amount they are willing to pay for new goods when asked hypothetical questions. Despite their appeal in eliminating hypothetical bias, marketers have been slow to adopt experimental auctions as a standard tool in pre-test market research. One issue that has slowed adoption of the methodology is the proliferation of auction mechanisms and the lack of clear guidance in choosing between mechanisms. In this paper, we provide insight into the theoretical properties of two incentive compatible value elicitation mechanisms, the BDM and Vickrey 2nd price auction, such that practitioners can make more informed...

Estimating the Impact of Food and Drug Administration Regulation of Cigarette Package Warning Labels and the Potential Added Impact of Plain Packaging: Evidence From Experimental Auctions Among Adult Smokers AgEcon
Thrasher, James F.; Rousu, Matthew C.; Hammond, David; Navarro, Ashley; Corrigan, Jay R..
Objective: To estimate differences in demand for cigarette packages with different packaging and health warning label formats. Methods: Adult smokers (n=404) in four states participated in experimental auctions. Participants bid on two of four experimental conditions, each involving a different health warning label format but with the same warning message: 1. text on 50% of pack side; 2. text on 50% of the pack front and back; 3. text with a graphic picture on 50% of the pack front and back; and 4. same as previous format, but without brand imagery. Results: Mean bids decreased across conditions (1. $3.52; 2. $3.43; 3. $3.11; 4. $2.93). Bivariate and multivariate random effects models indicated that there was no statistically significant difference...

GM FOOD LABELING POLICIES OF THE U.S. AND ITS TRADING PARTNERS AgEcon
Rousu, Matthew C.; Huffman, Wallace E..
Much of the international controversy of GM foods is due to labeling policies. Countries around the world have chosen different policies to label GM foods. We examine the labeling policies of several areas: the United States, the European Union, Australia, Japan, Canada, and China. We discuss each country's GM labeling policy, along with a brief history of how each country arrived at their current policy. We conclude by discussing how different policies are due to different ethical concerns of GM foods, along with the difference in perceived risks GM foods pose to health, the environment, and trade.

Improving the Nutrient Content of Food through Genetic Modification: Evidence from Experimental Auctions on Consumer Acceptance AgEcon
Colson, Gregory; Huffman, Wallace E.; Rousu, Matthew C..
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 levels of antioxidants and vitamin C achieved by moving genes from within the species, as opposed to across species. However, this premium is significantly affected by diverse information treatments injected into the experiments.

SHOULD THE UNITED STATES INITIATE A MANDATORY LABELING POLICY FOR GENETICALLY MODIFIED FOODS? AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
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 firms to voluntarily label their products as non-GM. This raises the question of whether a mandatory labeling or voluntary labeling policy is more efficient. Proponents of voluntary labeling policies say they are less expensive, because only the firms that wish to label their products must incur the labeling costs. In a mandatory labeling regime, all firms would need to incur additional costs, whether the costs are due to product testing, label design,...
