Expenditure on physicians’ services in Canada: Was Medicare a structural change?
运用协整分析，研究加拿大1960年代末引入医生服务国家医疗保险（Medicare）是否导致医生服务支出关系的结构性变化。结果支持单一协整方程适用于医保前后时期，未发现根本性结构变化。
This paper uses cointegration analysis to investigate the question of whether the introduction of national health insurance for physicians' services (Medicare) in the late 1960s caused a structural change in the relation driving national expenditure on physicians' services in Canada. The results support the existence of a single cointegration equation applying to both the Medicare and pre-Medicare periods. Structural change tests do not support the presence of a fundamental structural change associated with the introduction of Medicare.
