This study is the first attempt to elicit individual willingness to pay (WTP) for varying attributes of a specific food product, the organic egg, using three elicitation methods, namely, a real choice experiment (RCE), the Becker–DeGroot–Marschak (BDM) mechanism, and a RCE by using the BDM mechanism (RCE-BDM). The experimental setting allows for a comparison of these three methods. The mixed logit models in WTP space for the choice data and the random-effects Tobit model for the BDM data are used for the analyses. The results show that the individuals' WTP varies across elicitation methods. More specifically, the WTP of the RCE is lower than the WTP of the BDM experiment, and mixed results have been found while comparing the WTP of the RCE-BDM experiment and WTP of the BDM experiment. Lastly, individuals are willing to pay a premium for health, environment-friendly, and animal welfare attributes for all three elicitation methods: the health attribute's premium having the highest value followed by those of animal welfare and environment- friendliness. The results have not changed with information treatment indicating robustness of the findings. [EconLit Citations: C91, C35, D12].

通过三种诱导机制比较支付意愿：有机蛋制品的实验证据

本研究首次尝试使用三种诱导方法，即真实选择实验 (RCE)、Becker-DeGroot-Marschak ( BDM）机制，以及使用 BDM 机制的 RCE（RCE-BDM）。实验设置允许对这三种方法进行比较。选择数据的 WTP 空间中的混合 logit 模型和 BDM 数据的随机效应 Tobit 模型用于分析。结果表明，个体的 WTP 因诱导方法而异。更具体地说，RCE的WTP低于BDM实验的WTP，并且在比较RCE-BDM实验的WTP和BDM实验的WTP时发现了混合结果。最后，个人愿意为健康支付溢价，所有三种诱导方法的环境友好和动物福利属性：健康属性的溢价具有最高值，其次是动物福利和环境友好属性。结果没有随着信息处理而改变，表明结果的稳健性。[EconLit 引文：C91、C35、D12]。
