Provider performance reports and consumer welfare
研究了提供者绩效报告如何影响其行为（如抛弃弱势消费者）以及消费者福利，发现竞争激烈时报告会促使提供者抛弃消费者，统计调整可能加剧这一问题。
A provider's performance report consists of his service average outcome and volume. The two variables depend on the provider's private quality type and current demand, but he can raise his average outcome by dumping vulnerable consumers. Prospective consumers infer providers' qualities from their reports. Performance reporting drives some providers to dump consumers when competition is intense, but it may not reveal providers' qualities when their average quality is high. Statistical adjustment aiming at making reports independent of consumer characteristics can lead to more dumping, less informative reports, or both. There is more dumping when volume information is withheld and less dumping when ratings information is coarse.
