The degree to which disability benefit programs provide an adequate standard of living to those with work-limiting disabilities has long been overlooked in social policy research. This paper presents a framework for assessing disability-related decommodification and then applies that framework to an analysis of the Social Security Disability (SSD) programs in the United States. The paper draws on survey data from the Health and Retirement Study linked to administrative records from the Social Security Administration, and further compares the U.S. estimates to those from 27 other countries. The results indicate that more than 50 percent of older adults of working-age with work-disabilities in the U.S. do not receive SSD benefits, though rates of benefit receipt are higher than the average across other high-income countries. Those that receive SSD benefits, moreover, experience greater difficulty achieving an adequate standard of living, as measured by an index of financial security, than those with similar characteristics in the U.S. who do not receive disability benefits. The paper thus provides a framework for future policy research on benefit adequacy, while evaluating the availability and generosity of disability benefits in the U.S.

This policy perspective discusses three important social welfare programs—Social Security Disability Insurance, Medicare, and Temporary Aid to Needy Families—and offers an explanation of how they have expanded over time.

We examine the connection between taxes paid and benefits accrued under the Social Security Disability Insurance (SSDI) program on both the intensive and extensive margins. We perform these calculations for stylized workers given the existing benefit structure and disability hazard rates. On the intensive margin, we examine the effect of an additional dollar of earnings on the marginal payroll taxes contributed and future benefits earned. We find that the present discounted value of disability benefits received from an additional dollar of earnings, net of the SSDI payroll tax, generally declines with age, becoming negative around age 40 and reaching almost zero at age 63. On the extensive margin, we determine the effect of working an additional year on the additional payroll taxes and future benefits as a percentage of income. The return to working an additional year at an income level just large enough to earn Social Security credits for the year is large and positive through age 60. However, the return to working an additional full year is substantially smaller and becomes negative at approximately age 57. Thus, older workers face strong incentives to earn enough to obtain creditable coverage through age 60, but they face disincentives for additional earnings. In addition, workers aged 61 and older face work disincentives at any level of earnings. We repeat this analysis for stylized workers at different levels of earnings and find that, while the program transfers resources from high earners to low earners, the workers experience similar patterns in the returns to working.
