内容简介:

Platforms in a sharing economy match suppliers that provide a service with consumers who seek that service. The matching platform charges a price to the consumer and pays a wage to the supplier in every match. Determining the optimal matching mechanism for the platform is challenging because of heterogeneity on both supplier and consumer sides (suppliers vary in their service quality and cost and consumers vary in their valuations), private information (supplier cost is private), match interdependence (a supplier can be matched with at most one consumer and vice versa), and match-dependent platform value (value to the platform depends on who is matched with whom). We derive the optimal mechanism --- which includes the prices charged to consumers, wages offered to suppliers, and the matching rule --- for a sharing economy platform. We quantify the extent of gain the platform can achieve by adopting the optimal mechanism in place of the prevalent fixed-commission-rate scheme, in which the platform takes a fixed percentage of the price paid by the consumer as commission. Furthermore, we show that our optimal mechanism or minor variations of it has the potential to offer substantial gains under a wide variety of conditions. Our study extends the vast literature on mechanism design to sharing economy contexts.
