英文文献摘要:
Most of the existing literature deals with consumer willingness to pay for GM-free food, or consumer willingness to accept for GM food. However, it is well know that consumers have mixed views about GM foods. In this research, we do not presume that all consumers may just have positive or negative preferences about GM products. Rather, heterogeneous preferences are considered. This paper presents a contingent valuation questioning sequence and associated modeling approaches that allow identification of both positive and negative preferences. Willingness to pay (WTP) for the GM product is contrasted with willingness to accept (WTA) compensation to buy it.
现有文献大多涉及消费者对非转基因食品的支付意愿,或消费者对转基因食品的接受意愿。然而,众所周知,消费者对转基因食品的看法褒贬不一。在这项研究中,我们并不是假设所有的消费者都对转基因产品有正面或负面的偏好。相反,考虑的是异质偏好。本文提出了一个条件估值问题序列和相关的建模方法,允许识别积极和消极的偏好。对转基因产品的支付意愿(WTP)与购买该产品的接受补偿意愿(WTA)进行对比。
