Key Contributions / Features

• Life-cycle framework for SSI children (Davies, Rupp, and Wittenburg 2009): Lead author of the contextual anchor for the JVR special issue on SSI children in transition; documented the Sullivan v. Zebley history, NSCF family profiles, and longitudinal outcomes showing ~40% of childhood awardees still on SSI at age 45 with a flat earnings trajectory.
• SSA data infrastructure primer (Rupp and Davies ~2000): Co-authored reference documenting SSA's five core administrative databases (MBR, SSR, NDDS, MEF, NUMIDENT) and SIPP-SSA exact matching methodology; Project NetWork evaluation and SSI eligibility simulation as case studies.
• NSCF overview (Davies and Rupp 2005/2006, SSB): Overview of the National Survey of SSI Children and Families design and products — the primary source of descriptive data on the child SSI population as of 2000–2001.
• 1996 welfare reform impact (Karoly and Davies 2004): Evidence from matched SIPP-SSA data on the impact of the 1996 SSI childhood disability reforms.
