摘要 我们研究了生产过程标签和有关转基因技术潜在积极和/或消极方面的信息如何影响新型海鲜产品的需求。我们在一项针对 1,043 名美国海鲜消费者的在线选择实验中收集了数据。我们的结果表明，未提供转基因信息的参与者愿意为经过验证的非转基因和有机鱼片支付溢价，但要求为 Fed-GM 和转基因鱼片提供折扣。正面信息会降低有机、非转基因和转基因鱼片的支付意愿 (WTP)，而负面信息会显着提高有机鱼片的支付意愿并降低转基因鱼片的支付意愿。平衡的信息会降低有机和经过验证的非转基因鲑鱼的支付意愿，其程度与正面信息相似，并会降低转基因喂养和转基因鲑鱼的支付意愿，其程度与负面信息相似。根据我们的研究结果和更广泛的文献，我们就生产商和食品销售商如何鼓励他们与消费者之间的有效沟通提供了一些建议和讨论。
Abstract We investigate how production process labels and information about potential positive and/or negative aspects of GM technology affects demand for novel seafood products. We collected data during an online choice experiment distributed among 1,043 United States seafood consumers. Our results indicate participants not provided with GM information are willing to pay a premium for Verified Non-GM and Organic fillets, but require a discount for Fed-GM and GM fillets. Positive information reduces willingness to pay (WTP) for Organic, Non-GM and GM fillets, while negative information significantly increases WTP for Organic fillets and reduces WTP for GM fillets. Balanced information reduces WTP for Organic and Verified Non-GM salmon, similar in magnitude to positive information, and reduces WTP for GM-Fed and GM salmon, similar in magnitude to negative information. We provide some recommendations and discussion on how producers and food sellers might encourage effective communication between themselves and consumers based on our findings and the broader literature.
