Do Consumers Really Refuse to Buy Genetically Modified Food?
通过实验测量法国消费者对转基因食品的支付意愿，发现仅35%拒绝购买，42%在价格足够低时愿意购买，与调查显示的普遍反对形成对比。
We elicit willingness-to-pay information for similar food products that differ only in their content of genetically modified organisms (GMOs). Participants in the experiment are a demographically representative sample of French consumers. 35% of participants are unwilling to purchase products made with GMOs, 23% are indifferent or value the presence of GMOs, and 42% are willing to purchase them if they are sufficiently inexpensive. The results contrast with surveys that indicate overwhelming opposition to GM foods. There is a surplus to be gained from the segregation of the market for food products into a GMO-free segment and a segment allowing GMOs. Copyright 2004 Royal Economic Society.
