摘要：

In a random search framework, agents decide whether to visit the market, thereby forgoing their heterogeneous outside options. Coordination failure in market entry leads to congestion. We address the overparticipation issue by introducing a priority search program, which facilitates expedited matching in the market by charging a priority service fee. It naturally raises market entry costs and hence mitigates congestion. We establish that a profit-maximizing priority search program induces the socially optimal level of market participation. Additionally, priority search is superior to conventional intervention via the pricing scheme, which overcorrects the congestion problem and results in underparticipation. Our results are robust to several market design details and have important implications for regulating congested markets such as medical resource rationing and ride hailing.
