本文估计了管理式医疗计划对医疗服务利用的治疗效果，使用的数据来自美国两个同期的、具有全国代表性的家庭调查。本文利用基于模拟的计量经济学的最新进展，将登记纳入管理式医疗计划的内生性考虑在内，并确定管理式医疗登记与利用之间的因果关系。总的来说，两项调查的结果非常相似，为其外部有效性以及计量经济模型和估计方法提供了可信度。有重要的证据表明，自我选择纳入管理护理计划。在考虑了选择因素后，一个参加健康维护组织（HMO）计划的人比参加非管理医疗计划的人每年多看两次医生，多去急诊室0.1次。版权所有©2006约翰威利父子有限公司
This paper estimates treatment effects of managed care plans on the utilization of health care services using data from two contemporaneous, nationally representative household surveys from the USA. The paper exploits recent advances in simulation‐based econometrics to take the endogeneity of enrollment into managed care plans into account and identify the causal relationship between managed care enrollment and utilization. Overall, results from the two surveys are remarkably similar, lending credibility to their external validity and to the econometric model and estimation methods. There is significant evidence of self‐selection into managed care plans. After accounting for selection, an individual enrolled in an health maintenance organization (HMO) plan has 2 more visits to a doctor and has 0.1 more visits to the emergency room per year than would the same individual enrolled in a nonmanaged care plan.
