Data from a discrete choice experiment is used to investigate the implications of failing to account for attribute processing strategies (APSs). The research was designed to elicit the economic benefits associated with landscape restoration activities that were intended to remediate environmental damage caused by illegal dumping activities. In this paper we accommodate APSs using an equality constrained latent class model. By retrieving the conditional class membership probabilities we recover estimates of the weights that each respondent assigned to each attribute, which we subsequently use ensure unnecessary weight is not allocated to attributes not attended to by respondents. Results from the analysis provide strong evidence that significant gains in...

The mandatory Country of Origin Labeling (COOL) troubles beef exporters to the U.S. This study evaluates the extent that U.S. consumers are receptive to imported steak and their perception of food safety level of beef from various countries. In addition, using conjoint analysis, willingness to pay for strip loin steak from Australia, Canada and the United States is estimated along with several increasingly important food safeties and quality attributes in beef. We find that on average U.S. consumers are willing to pay significantly less for imported steaks.

Determinants of Decision to Pay a Price Premium for Modified Food by Consumers of the Republic of Korea

Kuchler, Fred.

Because each Federal agency uses a different valuation method to estimate the costs of illness, it is difficult to compare programs across agencies. As a first step toward generating a consensus on the current state of knowledge and deciding on a common approach, several agencies planned this conference, held September 14-15, 2000, at the University of Maryland, College Park, Maryland. The outcome of the conference will serve as guidance for a consensus approach.

The knowledge of the overall willingness-to-pay and the specific price premiums consumers accept when buying foods with less fat, saturated fat, sodium, sugar and more fiber shapes food manufacturer and distributor marketing strategies and supports the development of public health strategies. This study applies survey data collected in Korea to identify consumer profiles associated with the expressed willingness to pay a premium for foods with nutritionally desired attributes and, next, estimates the influence of consumer and household characteristics on the WTP a particular premium level for such foods. Results indicate the importance of socio-economic variables such as location, income and education, variables representing the risk of health problems...

This paper reports the results of an experiment involving a sample of 204 members of the public who were assessed on three occasions about their willingness to pay for the conservation of the mahogany glider. They were asked this question prior to information being provided to them about the glider and other focal wildlife species; after such information was provided, and finally after participants had had an opportunity to see live specimens of this glider. The mean willingness to pay of the relevant samples are compared and found to show significant variations. Theories are considered that help explain the dynamics of these variations. Serious concerns are raised about the capacity of information provision to reveal ‘true’ contingent valuations of public...

Auction market users and operators were surveyed regarding their source and use of livestock auction price information. Although important for marketing and to a lesser extent production decisions, only 30 percent preferred publicly reported prices over reports from market operators or other sources. The small share of market users willing to pay for public price reports suggests acceptable substitutes are available. Based on these results it is unlikely that user fees will be able to replace the current level of public support for auction market price reporting.

Verifying Credence Attributes in Livestock Production

Olynk, Nicole J.; Tonsor, Glynn T.; Wolf, Christopher A..

Livestock producers can respond to increasing consumer demand for certain production process attributes by providing verifiable information on the practices used. Consumer willingness to pay data were used to inform producer decision-making regarding selection of verification entities for four key production process attributes in the production of pork chops and milk. The potential for informing farm-level decision-making with information about consumer demand for product and production process attributes exists beyond the two products assessed as example cases in this analysis.

Experimental Economics and the Environment: Eliciting Values for Controversial Goods

Shogren, Jason F.; Parkhurst, Gregory M.; Hudson, Darren.

We illustrate the experimental method by examining bidding behavior for controversial goods, i.e., goods in which bidders have positive and negative values. Our results suggest that bidding behavior differs across auction type. Bidders with positive induced values bid sincerely in a WTP auction. Bidders bid conservatively, however, in the WTA auction, foregoing profitable opportunities. Informing bidders of their optimal strategy serves to attenuate bidding discrepancies but does not eliminate them. Treating the WTP and WTA auctions as equivalent given positive and negative values could lead one to overstate the costs relative to the benefits of the controversial good.

Some Problems in Estimating Willingness to Pay with Contingent Valuation Surveys: Case for Consumer Acceptance of Genetically Modified Food

Chern, Wen S.; Kaneko, Naoya.

This paper reports results from a U.S. national telephone survey on genetically modified foods. The objectives of this paper are to determine the effect of "indifference" response on the estimate of willingness to pay and to test the assumption of common marginal utility of income among respondents.

The Net Benefit of Saving the Asian Elephant: A Policy and Contingent Valuation Study

He, Na; Bernard, John C..

Auction experiments were used to examine demand and premium differences between organic, non-GM (genetically modified), and conventional versions for two pairs of fresh and processed foods. Results showed processed foods had greater substitutability among the versions than fresh products. Conventional versions were the least price sensitive, while non-GM versions were the most sensitive. Significant premium differences were found between fresh and processed foods for sweet corn and tortilla chips, but not for potatoes and potato chips. Results from random effects models mirrored these findings. In general, the extent of premium differences between fresh and processed versions appears dependent on the food product.

Reports results from a contingent valuation survey of willingness to pay for the conservation of the Asian elephant of a sample of urban residents living in three selected housing schemes in Colombo, the capital of Sri Lanka. Face–to–face surveys were conducted using an interview schedule. A non-linear logit regression model is used to analyse the respondents’ responses for the payment principle questions and to identify the factors that influence their responses. We investigate whether urban residents’ willingness to pay for the conservation of elephants is sufficient to compensate farmers for the damage caused by elephants. We find that the beneficiaries (the urban residents) could compensate losers (the farmers in the areas affected by human–elephant...

Loureiro, Maria L.; Umberger, Wendy J..

In this paper, we assess consumer willingness to pay for a mandatory country-of-origin labeling (COOL) program applied to beef ribeye steaks, chicken breasts, and pork chops, all labeled as “Certified U.S.” products. A consumer survey was mailed in spring and early summer 2003 to households in the continental United States. Results indicate that consumers are in general very concerned about food safety issues, viewing U.S. meats as the safest among the selection of countries considered. Nevertheless, consumer willingness to pay for Certified U.S. products is relatively small, although above the expected implementation costs associated with a mandatory labeling program. This finding coincides with the fact that only 36% of the sample favored consumers...

THE EFFECTS OF INFORMATION ON CONSUMER DEMAND FOR BIOTECH FOODS: EVIDENCE FROM EXPERIMENTAL AUCTIONS

Tegene, Abebayehu; Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F..

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 advising that the food was prepared with the aid of biotechnology. The authors designed and conducted an experimental auction to elicit consumers' willingness to pay for "genetically modified" (GM)-labeled and standard-labeled foods under different information regimes. The evidence gathered for vegetable oil, tortilla chips, and potatoes shows that labels matter. In particular, under all information treatments, consumers discounted food items labeled "GM" by an...

Asymmetric Willingness-to-Pay Distributions for Livestock Manure

Norwood, F. Bailey; Luter, Ryan L.; Massey, Raymond E..

The Environmental Protection Agency's new Concentrated Animal Feeding Operations (CAFO) regulations are forcing some farms to export livestock manure to off-farm acres. The regulation compliance cost depends on the willingness of neighboring crop producers to accept or pay for the manure. This study estimates a manure willingness-to-pay distribution for crop producers using a contingent valuation mail survey. A flexible parametric distribution is borrowed from the crop yield literature, which shows that manure willingness to pay is left-skewed. Most crop producers in our sample will pay a positive price close to the savings in commercial fertilizer, but approximately 25% require a payment before accepting manure.

The Role of Sensory Experiences and Information on the Willingness to Pay for Organic Wheat Bread

Boxall, Peter C.; Cash, Sean B.; Wismer, Wendy V.; Muralidharan, Vijay; Annett, Lisa E..

This study examined the size and the determinants of the price premium a sample of Edmonton-area consumers was willing to pay for organic wheat bread. The development of these premiums included consideration of providing information on health or environmental advantages of organic production and consideration of sensory (taste) acceptance. To do this conventional and organic wheat was grown under similar conditions and milled and baked into 60% whole wheat bread under identical conditions. Samples of these breads were presented to consumers for sensory acceptance and a survey of their attitudes, behaviours and characteristics. The survey included a closed-ended contingent valuation question to examine consumers' willingness-to-pay (WTP) premiums for the...

This case study concentrates on the extent of knowledge of members of the Australian public of Australia’s tropical bird species and their willingness to pay for their conservation. In order to place this issue in context, it first provides background information on the status of Australian bird species, focusing attention on species that occur in tropical Australia. Then, using survey results, this study considers the hypothesis that the public’s relative support for the conservation of different bird species depends on its comparative knowledge of their existence and status. Based on experimental results from a sample of residents of Brisbane, Queensland (Australia), it is found that their knowledge of bird species that occur exclusively in the...

E-commerce represents both threats to and opportunities for rural communities. This study addresses one element of the issue: farmers' willingness to substitute online merchants or national farm input stores for local businesses. Results of a conjoint analysis of contingent choice experiments suggest that farmers are willing to purchase from online or national stores outside their communities if compensated with lower prices or greater services. Results also demonstrate that the context of the input purchase, such as time constraints, was very important not only in valuing these services, but, more broadly, in terms of the farmer's loyalty to a local merchant.
