Health insurance menu design for large employers
为大型雇主设计健康保险计划菜单提供框架，利用哈佛大学数据估计计划选择和利用模型，评估成本分摊和计划多样性的收益。
Abstract We provide a framework for large employers designing a menu of health plan offerings that differ on both financial and nonfinancial dimensions. Using administrative data from Harvard University, we estimate a model of plan choice and utilization, and evaluate the benefits of cost sharing and plan variety. For this population of consumers, and a single plan with a generous out‐of‐pocket maximum and zero deductible, modest cost sharing of approximately 30% maximizes average employee surplus. Gains from offering choice are meaningful only if financial differentiation is paired with differentiation along other dimensions where consumer preferences are correlated with efficient coverage levels.
