Value-elicitation and value-formation properties of discrete choice experiment and experimental auctions
通过实地实验比较第二价格维克里拍卖与离散选择实验是否等价，发现两者在引出消费者对健康和环境可持续食品的偏好时存在差异，且离散选择实验更能揭示真实需求。
Abstract This paper tests if second-price Vickrey auction (SPVA) and discrete choice experiment (DCE) are isomorphic, and whether lack of isomorphism is due to value elicitation, value-formation or both. We conduct an artefactual field experiment that combines induced-value (IV) and home-grown (HG) procedures using SPVA and DCE. Induced-value preferences are elicited for tokens and HG preferences for multi-attribute lasagnes. Attributes are healthiness and environmental sustainability. Our results suggest that HG preferences differ across elicitation methods. This discrepancy is due to value-elicitation and value-formation. DCE is the most demand revealing approach and provides the highest premiums for healthy and environmentally sustainable lasagnes.
