520 3 $a"Patient cost-sharing for primary care and prescription drugs is designed to reduce the prevalence of moral hazard in utilization. Yet the success of this strategy depends on two factors: the elasticity of demand for those medical goods, and the risk of downstream hospitalizations by reducing access to beneficial health care. Amazingly, we know little about either of these factors for the elderly, the most intensive consumers of health care in our country. We remedy both of these deficiencies by studying a policy change that raised patient cost-sharing for retired public employees in California. We find that physician office visits and prescription drug utilization are very price sensitive; while direct comparison is difficult, the price sensitivity appears to greatly exceed that of the famous RAND Health Insurance Experiment (HIE). Moreover, unlike the HIE, we find large "offset" effects in terms of increased hospital utilization in response to the combination of higher copayments for physicians and prescription drugs. These offset effects are concentrated in patients for whom medical care is presumably efficacious: those with a chronic disease. Finally, we find that the savings from increased cost-sharing accrue mostly to the supplemental insurer, while the costs of increased hospitalization accrue mostly to Medicare; thus, there is a fiscal externality associated with cost-sharing increases by supplemental insurers. Our findings suggest that optimal insurance should be tied to underlying health status, with chronically ill patients facing lower cost-sharing. We also conclude that the externalities to Medicare from supplemental insurance coverage may be more modest than previously suggested due to these offsets"--National Bureau of Economic Research web site.
