Abstract:
We develop a theory of price discrimination in many-to-many matching markets in which agents' preferences are vertically and horizontally differentiated. The optimal plans induce negative assortative matching at the margin: agents with a low value for interacting with other agents are included in the matching sets of only those agents from the opposite side whose value for matching is sufficiently high (cross-subsidization). We deliver testable predictions relating the optimal matching plans and price schedules to the distribution of the agents' preferences and attractiveness. The analysis has implications for the design of business-to-business platforms, advertising, and cable TV packages.
