In 2001, Taiwan enacted a law for genetically modified food (GM foods) labeling. Beginning January 1st 2003, food containing more than 5% of GM ingredients must be labeled. Taiwan imports most of its soybeans from the United States. In order to assess the effects of the new policy, a telephone survey was conducted in 2002. A total of 257 interviews were completed. A typology of consumers' attitudes towards GM foods is constructed from the use of a multiple correspondence analysis and a classification method. Four profiles are identified: proponents, 52%, moderate opponents, 32.5%, extreme opponents, 12.5%, and those with no opinion, 5.5%. |

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. |
