Moral Hazard in Health Insurance

Addressing the challenge of covering heath care expenses-while minimizing economic risks.

Moral hazard-the tendency to change behavior when the cost of that behavior will be borne by others-is a particularly tricky question when considering health care. Kenneth J. Arrow's seminal 1963 paper on this topic (included in this volume) was one of the first to explore the implication of moral hazard for health care, and Amy Finkelstein-recognized as one of the world's foremost experts on the topic-here examines this issue in the context of contemporary American health care policy.

Drawing on research from both the original RAND Health Insurance Experiment and her own research, including a 2008 Health Insurance Experiment in Oregon, Finkelstein presents compelling evidence that health insurance does indeed affect medical spending and encourages policy solutions that acknowledge and account for this. The volume also features commentaries and insights from other renowned economists, including an introduction by Joseph P. Newhouse that provides context for the discussion, a commentary from Jonathan Gruber that considers provider-side moral hazard, and reflections from Joseph E. Stiglitz and Kenneth J. Arrow.
