Health Care Spending Risk, Health Insurance, and Payment to Health Plans
Journal Article


This chapter will deal with the actual and efficient functioning of health insurance in settings where risk (expected value) of medical spending or insurance benefits varies across individuals at a given point in time or over time for a given individual. It will deal with equilibrium in insurance markets with risk variation and will also deal with various configurations of information, the impacts on such markets of regulation motivated by risk variation, and the actual and optimal impact of governmental policies to deal with risk variation in national insurance systems. © 2012 Elsevier B.V.
