Abstract

This paper reports results from a U.S. national telephone survey ongenetically modified foods (vegetable oil, cornflakes, and salmon). Thesurvey featured a contingent valuation in which respondents chose betweenthe GM and non-GM alternatives with an option of indifference. The binomialand multinomial logit models yielded estimated willingness to pay (WTP) toavoid 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, GMcornflakes, GM-fed salmon, and GM salmon, respectively. The inclusion ofindifference option could increase the sample size and moderate the meanWTP.
