Summary:
This article analyzes the incentives of a monopolistic matchmaker to generate user-specific information. By merging two-sided market modeling with two-sided matching, we derive a micro-foundation of cross-side externalities as a function of the number of potential matches and the accuracy level of user-specific information. Incentives to make fixed investments in identification technologies are determined by two effects that work in opposing directions: Whereas economies of scale work in favor of platforms with large customer bases, expected improvements to match quality are more significant for small-scale platforms.
