In light of the declining pension coverage of low-income workers, policy makers have discussed requiring all employers to offer individual retirement accounts, similar to defined contribution plans. How likely to participate are workers who currently do not have access to a pension plan? We address this question by using plausibly exogenous variation in pensionplan availability to estimate the determinants of participation in a standard selection on unobservables model. We find that currently uncovered low-income workers are fairly likely to participate in a newly offered plan, yet they are much less likely to do so than currently covered workers.

This article explores the extent to which health, employment, family, or finances are associated with earlier-than-planned retirement using the Health and Retirement Study (HRS). The importance of any shock that drives early retirement depends both on its effect on those experiencing it and its prevalence in the population; therefore, the analysis proceeds in two steps. First, a probit regression is used to determine the strength of the relationship between the shocks and earlier-than-planned retirement, controlling for individual characteristics. Second, to incorporate the prevalence of the shock, counterfactual experiments are run to determine how much early retirement would be reduced in the population if these shocks did not occur. Our results indicate that health—both health “shocks” and initial poor health—is the most important factor in earlier-than-planned retirement, followed by involuntary job loss, and then changes within the family, especially a spouse’s retirement and having a parent move into the house. Changes in financial wealth do not have a significant impact on early retirement, but other, idiosyncratic factors may have some influence.

Over the last 25 years, the United States has seen a dramatic shift in the private sector away from defined benefit plans and towards defined contribution plans. While commentators constantly cite an increase in labor mobility as a major reason for the shift in the private sector from defined benefit to defined contribution plans, researchers to date have not been able to document any difference in mobility by pension type. This study argues that the inability to find such a relationship stems from ignoring the important role of job tenure. Using data from the Survey of Income and Program Participation (SIPP) and the Panel Study of Income Dynamics (PSID), the results of duration analyses that include the interaction of job tenure and pension type reveal that workers with between five and ten years of tenure at a firm are 23 % more likely to leave a job with a defined contribution plan than with a defined benefit plan. This difference is consistent with differences in the timing of benefit level entitlement between the two types of plans.
