The premise of this article is that an understanding of psychology and other social science disciplines can inform the effectiveness of the economic tools traditionally deployed in carrying out the functions of government, which include remedying market failures, redistributing income, and...

Including a matching contribution increases savings plan participation and contributions, although the impact is less significant than the impact of nonfinancial approaches. Conditional on participation, a higher match rate has only a small effect on savings plan contributions. In contrast, the...

This paper assesses the impact of employer-provided health insurance on job mobility by exploring the extent to which workers are 'locked' into their jobs because preexisting conditions exclusions make it expensive for individuals with medical problems to relinquish their current health...

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...

Economic theory predicts that an unexpected wealth windfall should increase consumption shortly after the windfall is received. We test this prediction using administrative records on over 40,000 401(k) accounts. Contrary to theory, we estimate a negative short-run marginal propensity to consume...

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...

We study a retirement savings plan with a default contribution rate of 12% of income, which is much higher than previously studied defaults. Twenty-five percent of employees had not opted out of this default 12 months after hire; a literature review finds that the corresponding fraction in plans...

If individuals have self-control problems, they may take up commitment contracts that restrict their spending. We experimentally investigate how contract design affects the demand for commitment contracts. Each participant divides money between a liquid account, which permits unrestricted...

What is the socially optimal level of liquidity in a retirement savings system? Liquid retirement savings are desirable because liquidity enables agents to flexibly respond to pre-retirement events that raise the marginal utility of consumption. On the other hand, pre-retirement liquidity is...

Can governments increase private savings by taxing savings up front instead of in retirement? Roth 401(k) contributions are not tax-deductible in the contribution year, but withdrawals in retirement are untaxed. The more common before-tax 401(k) contribution is tax-deductible in the contribution...
