Equity in Health Care Utilization: Further Tests Based on Hurdle Models and Swedish Micro Data
使用障碍模型和瑞典微观数据，分别检验医生和医院服务中寻求医疗的概率和获得服务数量是否存在水平不公平，发现收入、居住地规模等社会经济因素显著影响利用。
This paper tests the null hypothesis of no horizontal inequity in delivery of health care by use of count data hurdle models and Swedish micro data. It differs from most earlier work in three principal ways: First, the tests are carried out separately for physician and hospital care; second, the tests are carried out separately for the probability of seeking care and the amount of care received (given any use); and third, the tests are based on a model that includes several socioeconomic variables, e.g. income, education and size of community of residence. The paper rejects the hypothesis of no inequity because socioeconomic factors also have significant effects on utilization, e.g. income and size of community of residence. Size of community of residence has a positive significant effect on the frequency of physician visits but not on the probability of visiting a physician.
