Reconciling Findings on the Employment Effect of Disability Insurance
John Bound and Timothy A. Waidmann
Over the last 25 years the Social Security Disability Insurance Program (DI) has grown dramatically. During the same period of time employment rates for men with work limitations showed substantial declines in both absolute and relative terms. While the timing of these trends suggests that the expansion of DI was a major contributor to employment decline and raises questions about the targeting of disability benefits, studies using denied applicants suggest a more modest role for DI expansion. In order to reconcile these findings, we decompose total employment changes into population and employment changes for three categories: DI beneficiaries, denied applicants and non-applicants. Our results show that during the early 1990s, the growth in DI can fully explain the employment decline for men only under an extreme assumption about the employment potential of beneficiaries. For the period after the mid-1990s, we find little role for the DI program in explaining the continuing employment decline for men with work limitations.
