The Effect of Dental Insurance on the Use of Dental Care for Older Adults: A Partial Identification Analysis
利用部分识别框架处理内生选择和自报保险状态不可靠问题，估计全民牙科保险可使50岁以上老年人牙科服务使用率从75%升至约80%。
We evaluate the impact of dental insurance on the use of dental services using a potential outcomes identification framework designed to handle uncertainty created by unknown counterfactuals-that is, the endogenous selection problem-and uncertainty about the reliability of self-reported insurance status. Using data from the health and retirement study, we estimate that utilization rates of adults older than 50 years would increase from 75% to around 80% under universal dental coverage.
