We examine the effect of gaining prescription drug insurance as a result of Medicare Part D on use of prescription drugs, use of other medical services, and health for a nationally representative sample of Medicare beneficiaries. Given the heightened importance of prescription drugs for those with chronic illness, we provide separate estimates for those in poorer health. We find that gaining prescription drug insurance through Medicare Part D was associated with a 70% increase in the number of annual prescriptions, but that obtaining prescription drug insurance is not significantly related to use of other health care services or health, as measured by functional status and self-reported health. Among those in poorer health, we find that gaining prescription drug insurance was associate...

with Robert Kaestner, Swu Jane Lin: w12848
The Medicare Modernization Act was recently established, to provide limited drug coverage to the elderly. However, there is limited evidence on how drug coverage might affect health. The goal of this paper is to obtain "causal effects" of prescription drug coverage on drug use, use of other medical services and health of the elderly. We use fixed-effects analysis to control for unmeasured person-specific effects that may confound the relationships of interest. Results show prescription drug coverage, particularly public coverage, significantly increased the utilization of prescription drugs, but had no discernable effect on hospital admissions or health.
