Value elicitation for multiple quantities of a quasi‐public good using open ended choice experiments and uniform price auctions
比较了开放式选择实验、第二价格维克瑞拍卖和随机第N价格拍卖在估计准公共物品（动物福利产品）多数量支付意愿上的表现，发现仅用单单位支付意愿会低估总需求。
Abstract Choice experiments and experimental auctions have become popular mechanisms for estimating willingness to pay (WTP). However, these methods have primarily been used for estimating WTP for single units of goods. We analyze the results from experimental auctions and choice experiments in the context of multiple quantities of a quasi‐public good (animal welfare product). We show that the use of WTP values for a single unit of a product, a common practice in experimental valuation literature, can result in underestimation of aggregate demand. We use and compare open ended choice experiments (OECE), second price Vickrey auctions, and random N th price auctions as mechanisms for valuing WTP. Our results also suggest that individual level demand estimates from OECE are less elastic than demand estimates from uniform price auctions.
