RT Journal Article SR Electronic T1 The Impact of Leakages from 401(k)s and IRAs JF The Journal of Retirement FD Institutional Investor Journals SP jor.2021.1.096 DO 10.3905/jor.2021.1.096 A1 Alicia H. Munnell A1 Anthony Webb YR 2021 UL https://pm-research.com/content/early/2021/11/19/jor.2021.1.096.abstract AB This article summarizes what is known about leakages from existing studies and relates these results to detailed data on leakages in 2013 provided by Vanguard’s How America Saves. It then uses two data sets—the Survey of Consumer Finances and the Survey of Income and Program Participation—to estimate the impact of leakages on wealth at retirement.The Vanguard data are a critical component because they provide a comprehensive picture of assets and participant flows, whereas the surveys on which earlier studies were based tended to focus on one component, such as loans. A key limitation is that Vanguard’s population is probably wealthier than the general population.
