Is health care really a luxury?

Abstract

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.
