Aging countries should have an interest in policies to assist older beneficiaries in managing finances when there is a need. This project investigated the value of Medicare records as a guide to identifying persons with cognitive impairment in need of assistance with financial management. It used data from the Health and Retirement Study (HRS) on persons 65 and older, who consented to linkage to Medicare records at a rate of approximately 90 percent. Sampling weights were adjusted to account for linkage rates. The HRS survey data provided direct evidence on cognitive impairment and difficulty managing finances. The Medicare records are an imperfect guide to cognitive impairment as a medical diagnosis. About 40 percent of persons with impairment consistent with dementia are not identified in Medicare, and about 40 percent of persons with a diagnosis in Medicare records do not have impairment that severe. The records are even worse as a guide to who perceives or is perceived by others as needing assistance with financial management. Outside of institutional settings, Medicare records identify fewer than half the people needing assistance with financial management, and point to a substantial number of people who say they do not. The use of Medicare records alone to identify older beneficiaries in need of assistance with financial management would lead to substantial errors in coverage.

Parental investments in children can take one of three broad forms: (1) Time investments during childhood and adolescence that aid child development, and in particular cognitive ability (2) Educational investments that improve school quality and hence educational outcomes (3) Cash investments in the form of inter-vivos transfers and bequests. We develop a dynastic model of household decision making with intergenerational altruism that nests a child production function, incorporates all three of these types of investments, and allows us to quantify their relative importance and estimate the strength of intergenerational altruism. Using British cohort data that follows individuals from birth to retirement, we find that around 40% of differences in average lifetime income by paternal education are explained by ability at age 7, around 40% by subsequent divergence in ability and different educational outcomes, and around 20% by inter-vivos transfers and bequests received so far.

This is the first study to use longitudinal data to explore both the antecedents and consequences of fraud victimization in the older population. Because older persons are close to or past the peak of their wealth accumulation, they are often the targets of fraud. This paper reports on analysis of the Leave Behind Questionnaires (LBQs) fielded on Health and Retirement Study (HRS) respondents over three survey waves in 2008, 2010, and 2012. We evaluate the demographic determinants and risk factors of reporting financial fraud victimization in the survey, and explore whether there are demographic subgroups of older victims. In addition, we examine the financial, physical and psychological consequences of fraud. Overall results suggest that there is no single reliable predictor of fraud victimization across all three LBQ samples. When LBQ responses were pooled across survey years, we found that younger, male, better-educated, and depressed persons reported being defrauded significantly more often. Victimization was associated with lower nonhousing wealth in the combined sample controlling for other factors, but had no measurable impact on cognitive, psychological, or physical health outcomes. Future research should examine predictors and outcomes based on the type of financial fraud experienced and the amount of money lost.

This study analyzes the relative performance in terms of welfare of the current U.S. PAYG system compared to an array of cost equivalent alternative specifications of means-tested pension programs. We conduct our analysis under two different settings. While in the first setting, individuals have standard preferences, in the second setting individuals have self-control preferences. We show that the implications of the reform substantially differs across the two settings.

The Supplemental Security Income program (SSI) provides a guaranteed income for the elderly. As such it can serve to mitigate any deleterious effects of reductions in Social Security benefits that might result from any Social Security reform. However, participation in SSI among qualified individuals has proven to be low. We show that this low participation rate, just over 50%, observed at the program’s inception has continued to today with little if any change. We also find that transfers from children are far larger among eligible non-participants suggesting that family assistance may offset the need for public assistance.

Recent studies find that many workers do not return to the labor force after their applications for Disability Insurance (DI) are denied. It is, therefore, important to understand how this group funds their consumption. This paper uses the Survey of Income and Program Participation linked to administrative data to examine the social support participation behavior of rejected applicants. By following cohorts of individuals from 10 years before to 10 years after filing for DI, this paper shows that rejected DI applicants are at most 10 percent more likely to depend on social support programs than healthy workers. More general models show that at the time of application rejected applicants are 25 percent more likely to depend on social support programs than healthy workers. These effects decrease across time, but up to 10 years after filing, rejected DI applicants are still up to 12 percent more likely to depend on social support programs. These are the same levels of social support participation exhibited by DI beneficiaries. While rejecting more DI applicants may reduce DI outlays, these results suggest that rejected applicants are more likely to depend on other federally funded assistance programs to fund their (very) early retirement.

In this paper, we explore and compare how older and younger couple house- holds use adjustments in the wife’s labor supply to mitigate the e?ects of negative shocks to the husband’s employment status. Using di?erence-in-di?erences match- ing methods, we document a substantial added worker e?ect for younger house- holds. However, the wives of older men do not increase employment in response to their husbands’ negative employment shocks. Instead, in older households, fe- male unemployment increases. These results are consistent with older women being constrained by the labor market in the extent to which they can adjust their labor supply to mitigate the e?ects of spousal employment shocks. Our ?ndings suggest that spousal labor supply is not an e?ective intra-household insurance device for older households.

This paper develops a framework to analyze the actuarial adjustments faced by American workers who claim Social Security benefits before or after their Full Retirement Age (FRA). We derive the conditions under which these adjustments are “actuarially fair” (or “neutral”) and develop measures to characterize the devi- ation from the fair form. Fair adjustment schedules are increasing at an increasing rate in take-up age and become flatter as longevity rises. We document that the actuarial fit has improved across generations. Our baseline 3% discount rate scenario estimates that the current schedule deviates from its fair form by less than 1% for average-mortality beneficiaries, compared to 5.1% and 4.0% for male and female beneficiaries in 1980, respectively. The improvement is largely due to the increases in the Delayed Retirement Credit. For men, gains in life expectancy combined with the increase in the FRA also contributed to the improved fit. We predict that the designated increase in the FRA to age 67 will have little effect on the actuarial fit. We investi- gate schedules reflecting (further) increases in the retirement ages, as recommended by the President’s 2010 Fiscal Commission, and propose alternatives. We also discuss results from the analysis of the adjustments to spousal and widow(er) benefits.

Economists’ standard model assumes that improvements in total factor productivity (TFP) raise the marginal product of labor for all workers evenly. This paper uses an earnings dynamics regression model to study whether, in practice, older workers benefit less from TFP growth than younger workers. We utilize panel earnings data from the Social Security Administration’s Continuous Work History Sample. The data include workers of all ages, and we use annual figures for 1950-2004. Our first specification relies on BLS measurements of TFP. Our second model develops a new TFP measure using a principal components analysis. We find that although the earnings of younger workers track TFP growth 1-for-1, the earnings of older workers do not: we find, for example, that a 60-year-old male’s earnings grow only 85-90% as fast as TFP. Nevertheless, our analysis implies that in an economy with an aging labor force, gains from experience tend to outweigh older workers’ inability to benefit fully from TFP improvements.

Besides compensation and financial incentives, several other work-related factors may affect individual retirement decisions. Specifically, job characteristics such as autonomy, skill variety, task significance and difficulty, stress and physical demands, peer pressure and relations with co-workers, play a crucial role in determining psychological commitment to work at older ages. While financial preparedness for retirement and health shocks are often cited as main predictors of the choice to exit the labor force, there exists relatively little research documenting the extent to which the work environment itself and its interaction with economic variables influence retirement decisions. We document that job characteristics are associated with labor force transitions at older ages, in particular transitions to retirement and part-time employment. Additionally, we show that while personality traits do not directly drive labor force transitions, the effect of job characteristics on labor supply outcomes varies with the “intensity” of personality traits. We also document that job characteristics themselves are strongly related to personality traits. This suggests that, depending on their personality, individuals may select into specific jobs, whose characteristics ultimately shape their retirement paths.
