This paper explores the issues and pitfalls encountered when attempting to test empirically the hypothesis that physician, hospital, or any other input supply level induces increasing demand for health services in the strict sense of demand shift and, through that, increased demand for the input in question. Evidence is presented which suggests that an empirical test of the supplier induced demand (SID) hypothesis of the type traditionally performed may not in fact be feasible with cross-sectional aggregate data such as is usually used.
医生、医院或任何其他投入供应水平会在严格意义上的需求转移方面引发对医疗服务的需求增加,并由此增加对相关投入的需求。文中给出的证据表明,传统上所进行的那种对供应商诱导需求(SID)假设的实证检验,实际上对于通常使用的横截面汇总数据而言可能并不可行。
