Optimal Discoverability on Platforms
研究了平台在帮助买家发现新卖家时的最优可发现程度，权衡了更多交易与卖家因客户流失而退缩的效应，并分析了多种因素如何影响这一决策。
Choosing how easy to make it for buyers to discover new sellers is a key design decision for platforms. On one hand, enabling more discoverability generates more transactions and can be more attractive for sellers because they anticipate being discovered by new buyers. On the other hand, discoverability can make sellers more reluctant to participate because they anticipate their existing buyers will discover and purchase from other sellers. We model this fundamental trade-off and study how a platform’s optimal level of discoverability depends on various factors: the degree of substitutability between the sellers’ products; the standalone value of the platform’s tools; the size of the platform’s installed base of buyers; the nature of the platform’s fees, including its ability to charge differential fees depending on whether a transaction is with a seller’s existing buyers or not; the number of sellers; and asymmetries between sellers’ sizes.
