报告内容简介：Platforms in a sharing economy face suppliers who are heterogeneous in their service quality and their private opportunity cost. Moreover, consumers have heterogeneous valuations of the service offered by the suppliers. We investigate a platform’s optimal mechanism for matching suppliers with consumers in the sharing economy. The problem is challenging not only because of the multidimensional heterogeneity (i.e., consumer valuation, supplier quality, and supplier cost) and incomplete information (i.e., supplier cost), but also because a supplier can be matched with at most one consumer and vice versa and the platform’s value depends on who is matched with whom. We derive the optimal mechanism and characterize the optimal payment and matching rules. Our optimal mechanism extends the vast literature on mechanism design that has examined analogous issues in other contexts. We compare our optimal mechanism with the prevalent fixed-commission-rate scheme, in which the platform takes a fixed percentage of the price paid by the consumer as a commission, to illustrate the extent of gain the platform can achieve by adopting the optimal mechanism in place of fixed-commission-rate scheme.
