我们认为，平台市场使用的声誉机制存在两个问题。首先，买家可能会从单笔交易中得出关于平台质量的结论，从而导致卖家之间的声誉外部性。其次，由于我们讨论的各种原因，声誉会有偏见。我们使用eBay的数据记录了这些问题，并声称平台可以从识别和推广高质量的卖家中受益。我们创建了一个不可观察的卖家质量衡量标准，并通过一个优先考虑优质卖家的对照实验，展示了我们方法的好处。我们强调了声誉外部性的重要性，并制定了旨在创建更现实的平台市场模型的议程。
We argue that reputation mechanisms used by platform markets suffer from two problems. First, buyers may draw conclusions about the quality of the platform from single transactions, causing a reputational externality across sellers. Second, for a variety of reasons we discuss, reputations will be biased. We document these problems using eBay data and claim that platforms can benefit from identifying and promoting higher quality sellers. We create an unobservable measure of seller quality and demonstrate the benefits of our approach through a controlled experiment that prioritizes better quality sellers. We highlight the importance of reputational externalities and chart an agenda that aims to create more realistic models of platform markets.
