A. “The Decision to Delay Social Security Benefits: Theory and Evidence,” by John B. Shoven and Sita Nataraj Slavov (w17866, February 2012, .pdf format, 49p.).

Abstract:

Social Security benefits may be commenced at any time between age 62 and age 70. As individuals who claim later can, on average, expect to receive benefits for a shorter period, an actuarial adjustment is made to the monthly benefit amount to reflect the age at which benefits are claimed. We investigate the actuarial fairness of this adjustment. Our simulations suggest that delaying is actuarially advantageous for a large subset of people, particularly for real interest rates of 3.5 percent or below. The gains from delaying are greater at lower interest rates, for married couples relative to singles, for single women relative to single men, and for two-earner couples relative to one-earner couples. In a two-earner couple, the gains from deferring the primary earner’s benefit are greater than the gains from deferring the secondary earner’s benefit. We then use panel data from the Health and Retirement Study to investigate whether individuals’ actual claiming behavior appears to be influenced by the degree of actuarial advantage to delaying. We find no evidence of a consistent relationship between claiming behavior and factors that influence the actuarial advantage of delay, including gender and marital status, interest rates, subjective discount rates, or subjective assessments of life expectancy.

B. “Financial Sophistication in the Older Population,” by Annamaria Lusardi, Olivia S. Mitchell, and Vilsa Curto (w17863, February 2012, .pdf format, 49p.).

Abstract:

This paper examines data on financial sophistication among the U.S. older population, using a special-purpose module implemented in the Health and Retirement Study. We show that financial sophistication is deficient for older respondents (aged 55+). Specifically, many in this group lack a basic grasp of asset pricing, risk diversification, portfolio choice, and investment fees. Subpopulations with particular deficits include women, the least educated, persons over the age of 75, and non-Whites. In view of the fact that people are increasingly being asked to take on responsibility for their own retirement security, such lack of knowledge can have serious implications.

C. “Insurance as Delegated Purchasing: Theory and Evidence from Health Care,” by Robin McKnight, Jonathan Reuter, and Eric Zitzewitz (w17857, February 2012, .pdf format, 35p.).

Abstract:

Household demand for actuarially unfair insurance against small risks has long puzzled economists. One way to potentially rationalize this demand is to recognize that (non-life) insurance is an incentive-compatible means of engaging an expert buyer. To quantify the benefits of expert buying, we compare prices paid by the insured and uninsured for health care. In categories of health care where uncompensated care is more difficult to obtain (drugs, doctor office visits, and hospital outpatient visits), we find that insurers pay 10-20% less than the uninsured. For forms of care where payment by the uninsured is more likely to be negotiated after services are rendered (hospitalizations and emergency room visits) the uninsured pay about 30% less on average, due largely to the nontrivial share of uninsured who pay 5% or less of their billed charges. At least in settings where free services are difficult to obtain, expert buying is an important benefit of insurance. We discuss the implications of the delegated-purchasing view of insurance for con-sumer-driven health insurance and for self-insurance by employers.

D.  “Effects of Medicare Payment Reform: Evidence from the Home Health Interim and Prospective Payment Systems,” by Peter J. Huckfeldt, Neeraj Sood, José J Escarce, David C. Grabowski, and Joseph P. Newhouse (w17870, February 2012, .pdf format, 56p.).

Abstract:

Medicare continues to implement payment reforms that shift reimbursement from fee-for-service towards episode-based payment, affecting average and marginal reimbursement. We contrast the effects of two reforms for home health agencies. The Home Health Interim Payment System in 1997 lowered both types of reimbursement; our conceptual model predicts a decline in the likelihood of use and costs, both of which we find. The Home Health Prospective Payment System in 2000 raised average but lowered marginal reimbursement with theoretically ambiguous effects; we find a modest increase in use and costs. We find little substantive effect of either policy on readmissions or mortality.
