Many middle-income workers save for retirement through 401(k) plans. This study addresses the concern that low account balances of older workers may indicate that these vehicles are not sufficient to insure adequate retirement savings. In particular, the study shows that workers are not...

This paper uses numerical methods to compare optimal portfolios in tax-deferred and Roth-type savings accounts. Income and payroll taxes affect optimal portfolios in tax-deferred and Roth-type plans differently. For workers with assets in only one type of plan, the optimal equity share in a...

This paper examines why some employers provide matching contributions to 401(k) plans in company stock and explores the implications of match policy for employee retirement wealth. Unlike stock option grants to non-executives, a firm's decision to match in company stock does not appear to be...

Using panel data for nearly 1,000 companies during 1991 to 2000, this paper finds that employees allocated nearly 20 percent of their total 401(k) contributions to purchases of company stock, and then relates this share to plan design features and firm financial characteristics. We find that the...

We document large differences in trend changes in hours worked across OECD countries over the period 1956-2004. We then assess the extent to which these changes are consistent with the intratemporal first order condition from the neoclassical growth model. We find large and trending deviations...

Despite news reports suggesting a rise in 401(k) borrowing in recent years, we find that the share of eligible households with 401(k) loans in the 2007 Survey of Consumer Finances was about 15 percent, roughly what it has been since 1995. We find that the best predictors of 401(k) borrowing...
