Estimating the Distaste for Price Gouging with Incentivized Consumer Reports
通过实验测量人们愿意花多少钱举报疫情期间抬高防护用品价格的卖家，发现超过75%的人愿意付费举报，即使别人愿意以高价购买，这反映了对不公平或非法交易的厌恶。
Thirty-four states prohibit price increases during emergencies, and individuals take costly actions to report violators. We measure experimentally the willingness to pay to report sellers who increase prices of personal protective equipment. Over 75 percent of subjects pay to report, even if others are willing to buy at those prices. We argue that reports contain information about a desire to prevent or punish third-party transactions at unfair or illicit prices. Reports are partially driven by a distaste for firm profits or markups, implying that the distribution of surplus between producers and consumers matters for welfare.
