Weaver's paper aims to compare the SSI and Social Security Disability Programs, specifically how federal support compares between approved and denied applicants for such programs (as well as other beneficiaries and the general population). The paper aims to discuss the use of survey data in the 2013 SIPP Panel that helps identify populations denied such benefits.(Survey data is less reliable than the administrative data but the latter is not often made publicly available and can have implications of future research and studies.)
