This chapter summarizes the many aspects of public policy for health care. I first consider government policy affecting individual behaviors. Government intervention to change individual actions such as smoking and drinking is frequently justified on externality grounds. External costs of...

We study the impact of health insurance expansion in the US on health expenditure, longevity growth and welfare in an overlapping generations economy in which individuals purchase health care to lower mortality. We consider three sectors: final goods production; a health care sector, selling...

We examine the welfare effects of the interaction of three types of technological progress in medicine and health insurance; some paradoxes emerge. The model specifies three types of people: W (well); H (sick with high cure rate if treated); and L (sick with low cure rate if treated). There are...

We model a health insurance market where rising cure rates for a disease may paradoxically diminish welfare and even negate the desirability of health insurance altogether. In the model, rising cure rates can affect welfare in two ways: (1) directly, by improving some individuals' health, and...

We study the design of nonlinear reimbursement rules for expenses on secondary preventive and on therapeutic care. With some probability individuals are healthy and do not need any therapeutic health care. Otherwise they become ill and the severity of their disease is realized and identifies...

Theoretical models predict asymmetric information in health insurance markets may generate inefficient outcomes due to adverse selection and moral hazard. However, previous empirical research has found it difficult to disentangle adverse selection from moral hazard in health care. We empirically...

This paper studies a market for a medical product in which there is perfect competition among health insurers, while the good is sold by a monopolist. Individuals differ in their severity of illness and there is ex post moral hazard. We consider two regimes: one in which insurers use coinsurance...
