Standard theories of insurance, dating from Rothschild and Stiglitz (1976), stress the role of adverse selection in explaining the decision to purchase insurance. In these models, higher risk people buy full or near-full insurance, while lower risk people buy less complete coverage, if they buy...

This paper examines the standard test for asymmetric information in insurance markets: that its presence will result in a positive correlation between insurance coverage and risk occurrence. We show empirically that while there is no evidence of this positive correlation in the long-term care...

We examine whether unregulated, private insurance markets efficiently provide insurance against reclassification risk (the risk of becoming a bad risk and facing higher premiums). To do so, we examine the ex-post risk type of individuals who drop their long-term care insurance contracts relative...

The introduction of Medicare in 1965 was the single largest change in health insurance coverage in U.S. history. Many economists and commentators have conjectured that the introduction of Medicare may have also been an important impetus for the development of new drugs that are now commonly used...

Recent work by a number of economists has opened a debate about the role played by intergenerational transfers. Using the new Health and Retirement Survey (HRS), we are better able to address the issues involved. Contrary to the current literature on bequests, we do not find that parents give...

In the Health and Retirement Survey respondents were asked about the chances they would live to 75 or to 85, and the chances they would work after age 62 or 65. We analyze the responses to determine if they behave like probabilities, if their averages are close to average probabilities in the...

We study the influence of job characteristics on prospective retirement as measured by the probability of working past age 62 or 65. The characteristics fall into three broad classes: physical and mental requirements, job flexibility including employer accomodation to older workers, and...

The choice of a retirement date is one of the most important decisions facing older workers. It is a decision that will affect their economic well-being for the remainder of their lives. One of the factors that undoubtedly impacts this choice is the worker's health. However, the many studies...

The same low participation rates which plague many welfare programs have been observed among the elderly eligible for Supplemental Security Income (SSI). A number of hypotheses have been offered to explain the low enrollment, but none has attracted universal acceptance. In this paper I use the...

Although expectations (or subjective probability distributions) play a prominent role in models of decision-making under uncertainty, we have very little data on them and are instead forced to base our models on unverifiable assumptions. Macroeconomic models often assume rational expectations,...
