Prescription Drug Insurance

We examine the impact of the expansion of public prescription-drug insurance coverage from Medicare Part D and find evidence of substantial crowd-out. Using the 2002–2007 waves of the Medical Expenditure Panel Survey, we estimate the extension of Part D benefits resulted in 75 percent crowd-out of both prescription-drug insurance coverage and expenditures of those 65 and older. Part D is associated with sizeable reductions in out-of-pocket spending, much of which has accrued to a small proportion of the elderly. On average, we estimate a welfare gain from Part D comparable to the deadweight cost of program financing. (JEL H51, I18, J14)

Prescription Drug Insurance

I examine whether lack of an individual market for prescription drug insurance causes individuals to delay retirement. Exploiting the 2006 introduction of Medicare Part D, which subsidized drug insurance for Americans over age 65, I use a triple-differences design that compares labor outcomes of individuals with retiree health insurance up to age 65 to those with insurance for life, before and after age 65, before and after 2006. I find that those with benefits only to age 65 decreased full-time work by 8.4 percentage points, of which 70 percent was due to transitions to part-time work. (JEL G22, H51, I13, I18, J14, J26)

Enrollment Data

I use the Medicare Part D prescription drug insurance market to examine the dynamics of firm interaction with consumers on an insurance exchange. Enrollment data show that consumers face switching frictions leading to inertia in plan choice, and a regression discontinuity design indicates initial defaults have persistent effects. In the absence of commitment to future prices, theory predicts firms respond to inertia by raising prices on existing enrollees, while introducing cheaper alternative plans. The complete set of enrollment and price data from 2006 through 2010 confirms this prediction: older plans have approximately 10 percent higher premiums than comparable new plans.

Investment Portfolios

Economic theory suggests that medical spending risk affects the extent to which households are willing to accept financial risk, and consequently their investment portfolios. In this study, we focus on the elderly for whom medical spending represents a substantial risk. We exploit the exogenous reduction in prescription drug spending risk due to the introduction of Medicare Part D in the U.S. in 2006 to identify the causal effect of medical spending risk on portfolio choice. Consistent with theory, we find that Medicare-eligible persons increased risky investment after the introduction of prescription drug coverage, relative to a younger, ineligible cohort.

Financial Characteristics

We evaluate the choices of elders across their insurance options under the Medicare Part D Prescription Drug plan, using a unique dataset of prescription drug claims matched to information on the characteristics of choice sets. We document that elders place much more weight on plan premiums than on expected out-of-pocket costs; value plan financial characteristics beyond any impacts on their own financial expenses or risk; and place almost no value on variance-reducing aspects of plans. Partial equilibrium welfare analysis implies that welfare would have been 27 percent higher if patients had all chosen rationally. (JEL D12, I11, J14)
