We compare consumers' attitude towards and willingness to pay (WTP) for gene-edited (GE) apples in Europe and the US. Using hypothetical choices in a lab and different technology messages, we estimate WTP of 162 French and 166 US consumers for new apples, which do not brown upon being sliced or cut. Messages center on (i) the social and private benefits of having the new apples, and (ii) possible technologies leading to this new benefit (conventional hybrids, GE, and genetically modified (GMO)). French consumers do not value the innovation and actually discount it when it is generated via biotechnology. US consumers do value the innovation as long as it is not generated by biotechnology. In both countries, the steepest discount is for GMO apples, followed by GE apples. Furthermore, the discounting occurs through "boycott" consumers who dislike biotechnology. However, the discounting is weaker for US consumers compared to French consumers. Favorable attitudes towards sciences and new technology totally offset the discounting of GE apples.
我们比较了欧洲和美国消费者对基因编辑(GE)苹果的态度和支付意愿(WTP)。通过实验室中的假设选择和不同的技术信息,我们估计了 162 名法国消费者和 166 名美国消费者对新型苹果的支付意愿,这种新型苹果切片或切开后不会变色。信息主要集中在(i)拥有这种新型苹果的社会和私人利益,以及(ii)可能导致这种新利益的技术(传统杂交、GE 和基因修饰(GMO))。法国消费者并不重视这项创新,实际上当它是通过生物技术产生时会对其进行折扣。只要创新不是通过生物技术产生,美国消费者就会重视这项创新。在这两个国家,对 GMO 苹果的折扣最大,其次是 GE 苹果。此外,通过“抵制”生物技术的消费者进行的抵制会导致折扣。然而,与法国消费者相比,美国消费者的折扣幅度较弱。对科学和新技术的有利态度完全抵消了对 GE 苹果的折扣。
