Retirement savings abandonment is a rising concern connected to defined contribution systems and default enrollment. We use tax data on Individual Retirement Accounts (IRAs) to establish that for a recent cohort, 0.4% of retirement-age individuals abandoned an aggregate of $66 million, proxied by a failure to claim over ten years after a legal requirement to do so. Analysis of state unclaimed property databases suggests that workplace defined contribution plans are abandoned at a higher rate than IRAs. Finally, regression discontinuity estimates show that certain accounts created by default enrollment are at higher risk of abandonment by passive savers.

We combine quasi-experimental variation in spousal death and age eligibility for survivors benefits using US tax records to study the effects on American households’ labor supply and the design of social security’s survivors insurance. Benefit eligibility at the exact age of 60 induces sharp reductions in the labor supply of newly widowed households, highlighting the value of survivors benefits and the liquidity they provide following the shock. Among eligible widows, the spousal death event induces no increases in labor supply, suggesting little residual need to self-insure. Using theory, we underscore the program’s protective insurance role and its high valuation among survivors. (JEL D12, D91, G22, G51, H55, J16, J22)
