摘要
We offer a unified screening perspective to study network interventions in a product market with positive network externalities when each agent has private information on their network degrees (i.e., susceptibility and influence). As long as the agents’ incentive constraints are respected, we show that the principal directly screens an agent along the susceptibility dimension and indirectly infers their implied influence. Based on this simplification, we fully characterize the optimal intervention policies for both a profit-maximizing monopolist seller and a welfare-maximizing social planner. We also analyze the two problems under a quadratic intrinsic value and show additional insights on the optimal allocation, pricing patterns and respective surplus for the principal and the agents. Our analysis not only offers practical suggestions for interventions in product markets with positive network externalities, but also sheds light on the value of network information.
