The role of advisory provision and policy objective information in dairy farmers’ preferences for methane-reducing feed additives
通过320名瑞典奶农的离散选择实验，研究发现饲料添加剂的环境效益和农场顾问提供信息能提高采纳率，而政策目标信息降低了农户对30%甲烷减排水平的接受意愿。
Abstract In a discrete choice experiment with 320 Swedish dairy farmers, we investigate preferences for methane-reducing feed additives, finding that higher environmental effectiveness and a farm advisor as the provider of accompanying information increase the probability of adoption. Additionally, an information treatment on methane reduction policy objectives lowers willingness to accept for the 30 per cent methane-reduction level of the feed additive. Latent class analysis shows that innovation-friendly farmers are more likely to be adopters, while those with stronger pro-animal-welfare attitudes are not. Finally, we predict feed additive market shares and discuss the economic implications for emissions reduction.
