Much of the work which has led to a widely held view that the income elasticity of health care spending exceeds one has been based on international cross-section data, or on pooled cross-sections and time series. In this paper we re-examine this view in the context of long-run equilibrium relationships between non-stationary time series, possibly including autonomous trends. Our results cast doubt upon the usefulness of pooling and upon the notion of an elasticity above one.
许多研究得出了一种被广泛认可的观点，即医疗保健支出的收入弹性超过1，这些研究大多基于国际横截面数据，或汇总的横截面数据和时间序列。在本文中，我们在非平稳时间序列（可能包括自主趋势）之间的长期均衡关系背景下重新审视这一观点。我们的结果对汇总数据的有用性以及弹性大于1的概念提出了质疑。
