评估消费者对转基因食品的看法和支付意愿一直是农业经济学实证研究中最活跃的领域之一。在过去的15年里，研究人员通过调查和实验方法，对消费者购买转基因食品的意愿进行了100多次评估。在这篇综述中，我们探讨了一些悬而未决的问题，这些问题与三个问题有关，在考虑构成消费者对转基因食品偏好证据的个人贡献总和时，这些问题至关重要。
Assessing consumer perceptions and willingness to pay for genetically modified (GM) foods has been one of the most active areas of empirical research in agricultural economics. Researchers over the past 15 years have delivered well over 100 estimates of consumers' willingness to pay for GM foods using surveys and experimental methods. In this review, we explore a number of unresolved issues related to three questions that are critical when considering the sum of the individual contributions that constitute the evidence on consumer preferences for GM foods.
