This volume presents innovative research on issues of importance to the well-being of older persons: labor market behavior, health care, housing and living arrangements, and saving and wealth.

Specific topics include the effect of labor market rigidities on the employment of older workers; the effect on retirement of the availability of continuation coverage benefits; and the influence of the prospective payment system (PPS) on rising Medicare costs. Also considered are the effects of health and wealth on living arrangement decisions; the incentive effects of employer-provided pension plans; the degree of substitution between 401(k) plans and other employer-provided retirement saving arrangements; and the extent to which housing wealth determines how much the elderly save and consume.

Two final studies use simulations that describe the implications of stylized economic models of behavior among the elderly. This timely volume will be of interest to anyone concerned with the economics of aging.

"Defensive medicine" is a potentially serious social problem: if fear of liability drives health care providers to administer treatments that do not have worthwhile medical benefits, then the current liability system may generate inefficiencies many times greater than the costs of compensating malpractice claimants. To obtain direct empirical evidence on this question, we analyze the effects of malpractice liability reforms using data on all elderly Medicare beneficiaries treated for serious heart disease in 1984, 1987, and 1990. We find that malpractice reforms that directly reduce provider liability pressure lead to reductions of 5 to 9 percent in medical expenditures without substantial effects on mortality or medical complications. We conclude that liability reforms can reduce defensive medical practices.
