选民比消费者更注重食品安全

Voters are more willing to pay for a decreased risk of food-related illness than consumers, but female consumers are more willing to pay than male consumers, according to an international team of researchers. "The question is, what would consumers prefer?" said Amit Sharma, associate professor of hospitality management and finance, Penn State. "Would they prefer a market-driven, or a policy-driven approach? Either of those two approaches could lead to some price increase. Improving quality costs money, and food safety is no different."

Sharma and colleagues wanted to know whether people would pay more for a lowered risk of a food-related illness, and in particular whether their choices would vary if they were thinking about the issue from a consumer perspective as opposed to a voter perspective.

"The question is whether it matters whether we elicit consumer or citizen preferences when valuating food safety," said the researchers in a recent issue of Food Policy.

The researchers created two surveys for distribution to participants. One survey asked about the participant's willingness to pay more at a neighborhood restaurant to ensure reduced risk of food-related illness. The other asked whether the participant would vote yes or no for regulations to reduce this risk that would result in the same increase in restaurant prices. Participants were asked about their willingness to pay increased amounts -- from none, to 1 to 5 percent, to over 30 percent of the meal price -- for a lowered risk of food-related illness. Respondents answered the survey for a 25 percent, 50 percent, and 75 percent reduction in risk.

Over the course of a semester, the team collected survey responses from 864 people at a university campus restaurant. Participants covered a range of ages, income levels and educations levels and included local residents, students and university employees.

The researchers also developed models, taking into account variables including participant gender and age, to determine whether the participants responded to the survey differently as consumers than as voters.
