Crime and Early Retirement Among Older Americans
Dan Silverman and Olivia S. Mitchell
BWP2004-01
This paper investigates the relationship between local crime rates and the retirement decisions of older Americans. We do so by linking data from the Health and Retirement Study with measures of local crime patterns taken from the Federal Bureau of Investigation's Unified Crime Reports. If we condition on crime rates alone, there is either a weakly positive or no relationship between local crime patterns and older men's propensity to retire early. But unobservable factors associated with early retirement may be correlated with residence in higher-crime rate cities, so next we condition on both the expectation for the crime rate and deviations from average crime levels. We find a positive and statistically significant association between early retirement and expectations for murder rates, and a positive but, on average, imprecisely estimated positive association between early retirement and unexpected increases in crime. The effect of unanticipated increases in crime is greatest, and significant for those in poor health. In this latter group, men are 14 percent more likely to retire early given a standard deviation increase in unexpected murder rates. These findings are consistent with a pattern of more early retirement among those who live in higher crime areas, and earlier retirement among those in poor health when crime levels rise above anticipated levels.

Death Spiral or Euthanasia? The Demise of Generous Group Health Insurance Coverage
Mark Pauly, Olivia Mitchell, and Peter Zeng
BWP2004-02
Employers must determine which sorts of healthcare insurance plans to offer employees and also set employee premiums for each plan provided. Depending on how they structure the premiums that employees pay across different healthcare insurance plans, plan sponsors alter the incentives to choose one plan over another. If employees know they differ by risk level but premiums do not fully reflect these risk differences, this can give rise to a so-called "death spiral" due to adverse selection. In this paper, we use longitudinal information from a natural experiment in the management of health benefits for a large employer to explore the impact of moving from a fixed dollar contribution policy to a risk-adjusted employer contribution policy. Our results suggest that implementing a significant risk adjustment had no discernable effect on adverse selection against the most generous indemnity insurance policy. This stands in stark contrast to previous studies, which have tended to find large impacts. Further analysis suggests that previous studies which appeared to detect plans in the throes of a death spiral, may instead have been experiencing an inexorable movement away from a non-preferred product, one that would have been inefficient for almost all workers even in the absence of adverse selection.

Modeling Lifetime Earnings Paths: Hypothetical versus Actual Workers
Andrew Au, Olivia S. Mitchell, and John W. R. Phillips
BWP2004-03
To assess the distributional effects of social security reform proposals, it is essential to have good information on real-world workers' lifetime earnings trajectories. Until recently, however, policymakers have relied on hypothetical earnings profiles for policy analysis. We use actual lifetime earnings data from the Health and Retirement Study (HRS) to compare actual workers' covered earnings profiles to these hypothetical profiles. We show that the hypothetical profiles do not track earnings patterns of current retirees; thus lifetime pay levels are much higher than for most HRS workers. Therefore, using hypothetical profiles could misrepresent benefits paid and taxes collected under such reforms.

Plan Design and 401(k) Savings Outcomes
James J. Choi, David Laibson, Brigitte C. Madrian
BWP2004-04
We assess the impact of 401(k) plan design on four different 401(k) savings outcomes: participation in the 401(k) plan, the distribution of employee contribution rates, asset allocation, and cash distributions. We show that plan design can have an important effect on all of these savings outcomes. This suggests an important role for both employers in determining how to structure their 401(k) plans and government regulators in creating institutions that encourage or discourage particular aspects of 401(k) plan design.

Employee Stock Purchase Plans
Gary V. Engelhardt and Brigitte C. Madrian
BWP2004-05
Employee stock purchase plans (ESPPs) are designed to promote employee stock ownership broadly within the firm and provide another tax-deferred vehicle for individual capital accumulation in addition to traditional pensions, 401(k)s, and stock options. We outline the individual and corporate tax treatment of ESPPs and the circumstances under which ESPPs will be preferred to cash compensation from a purely tax perspective. We then examine empirically ESPP participation using administrative data from 1997-2001 for a large health services company that employs approximately 30,000 people. The picture that emerges from the analysis of these data suggests that there is substantial non-participation in these plans even though all employees could increase gross compensation through participation. We discuss a number of potential explanations for non-participation.
