Recent legislation has affected the populations served by the Social Security Administration's (SSA's) disability programs. The Contract with America Advancement Act of 1996 mandated that persons whose disability determination was based on drug addiction or alcoholism be removed from the Supplemental Security Income and Social Security Disability Insurance rolls. The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (later amended by the Balanced Budget Act of 1997) tightened the SSI eligibility criteria for children and converted the Aid to Families with Dependent Children program into a block grant, Temporary Assistance for Needy Families. This article describes the design of three related studies evaluating the direct and indirect effects of these policy changes on SSA's disability populations. It describes the methodological challenges of the studies and the strategies used to overcome them. It also presents early evidence from the three studies and discusses future directions.

This article summarizes the results of a major social experiment initiated by the Social Security Administration to test case management as a tool of promoting employment among persons with moderate to severe disabilities. This comprehensive analysis shows the benefits of using an experimental design to derive realistic net outcome estimates. While the results cannot be generalized to other case management interventions, they are nevertheless instructive for planning new initiatives.

This article compares participation rates in three existing voluntary individual account-type plans—individual retirement accounts (IRAs), 401(k)s, and the federal Thrift Savings Plan (TSP)—in an effort to analyze who might participate in a voluntary individual account system.

In this article we explore the extent of and reasons for attrition in the New Beneficiary Survey (NBS) between the first interview in 1982 and the followup interview in 1991. We examine a variety of potential determinants of attrition, separating the probability of attrition due to death from a refusal to be interviewed. Because the NBS sample is drawn from and linked to Social Security administrative records, information on mortality as a cause of attrition is exact. Hence, we are able to examine differences in the patterns and predictors of attrition due to these two causes of attrition and differences between attrition among retired and disabled workers.
