对成绩单的估计反应可能反映了在没有这些反应的情况下对质量的了解（“基于市场的了解”）。使用面板数据的医疗保健组织，我们研究了注册和质量之间的关系之前和之后的报告卡邮寄给4000万医疗保险受益人在1999年和2000年。我们发现，消费者从公开的成绩单和市场来源中学习，后者的影响更大。当HMO质量的差异更大时，消费者对这两种信息来源特别敏感。成绩单的效果取决于受益人对消费者满意度评分的反应。
Estimated responses to report cards may reflect learning about quality that would have occurred in their absence ("market-based learning"). Using panel data on Medicare HMOs, we examine the relationship between enrollment and quality before and after report cards were mailed to 40 million Medicare beneficiaries in 1999 and 2000. We find consumers learn from both public report cards and market-based sources, with the latter having a larger impact. Consumers are especially sensitive to both sources of information when the variance in HMO quality is greater. The effect of report cards is driven by beneficiaries' responses to consumer satisfaction scores.
