Perspectives in health economics.

This paper, originally presented at the Institute d'Etudes Politiques de Paris, October 12, 1993, provides a perspective on envisioned changes in the practice of health economics. Foreseen changes include: (1) Study of more homogeneous units of analysis; (2) More original data gathering; (3) Increased attention to uncertainty and the supply of and demand for information; (4) Increased attention to institutional structures and their effects on economic behaviour; (5) Expansion of relevant tools for studying economic issues in health care; and (6) Continuing breakdown of disciplinary barriers between health economics and other disciplines. Of these, the two overriding features will be increased emphasis on understanding the many roles of uncertainty in economic behaviour, institutions, and outcomes in health care, and in the use of more and more 'micro' data to study these issues.
