This paper illustrates the importance of consumer segments for the estimation of the distribution of sample willingness to pay. We find evidence that those who prefer non-GM have a different marginal utility of income and that naïve pooling of consumer segments may yield a misleading recommendation for both agribusinesses and policy makers.

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.

This paper estimates the impact of generic and brand advertising on the demand for peanut butter in the U.S. An error correction model is estimated with quarterly data from 1985 to 2004 to study both the short- and long-run adjustments. The results indicate that brand advertising has a significant but short-lived effect on aggregate consumption while generic advertising has little short-run but significant long-run effects.

This paper finds Taiwanese consumers' willingness to pay a premium on the non-GM food differs from their willingness to accept a discount on the GM food. It further finds that the non-GM choosers are more committed to the non-GM food than the GM choosers to the GM food.

This paper reports results from a pilot U.S. national telephone survey on genetically modified foods (vegetable oil, cornflake cereal, and salmon). The survey featured contingent valuation in which respondents chose between the GM and non-GM alternatives. The binary and multinomial logit models yield estimated willingness to pay to avoid the GM alternatives. Perceived risk of GM food is an important determinant of GM choice along with the price. Respondents are willing to pay 41.2%, 31.4%, 40.9%, and 52.5% of the base prices to avoid GM vegetable oil, GM cornflakes, GM-fed salmon, and GM salmon, respectively.

Willingness to Pay for PEF-processed Orange Juice: Evidence from an Auction Experiment

This paper reports results from a U.S. national telephone survey on genetically modified foods (vegetable oil, cornflakes, and salmon). The survey featured a contingent valuation in which respondents chose between the GM and non-GM alternatives with an option of indifference. The binomial and multinomial logit models yielded estimated willingness to pay (WTP) to avoid the GM alternatives. Respondents were willing to pay 20.9%, 14.8%, 28.4%, and 29.7% of the base prices to avoid GM vegetable oil, GM cornflakes, GM-fed salmon, and GM salmon, respectively. The inclusion of indifference option could increase the sample size and moderate the mean WTP.

This paper presents the results of experimental auctions of the orange juice processed with the pulsed electric field (PEF) technology. A series of experimental auctions are conducted to elicit consumers' willingness to pay (WTP) for the PEF orange juice along with WTP for three other types of orange juice: unprocessed (fresh), thermally processed not-from-concentrate, and thermally processed from-concentrate orange juice. We adopt the second-price sealed-bid auction. With this auction method, the highest bidder claims the product at the price equal to the second highest bid. The auction results show that unprocessed "fresh" juice had the highest mean bidding price of $2.68/half gallon. The second-highest mean bidding price was for PEF juice at...
