David Stapleton is a Senior Fellow and was the director of Mathematica’s Center for Studying Disability Policy from 2007 through 2017. He also directs Mathematica’s cooperative agreement with the Social Security Administration (SSA) for the agency's Disability Research Consortium. Since 1991, Stapleton’s research has focused on the impacts of public policy on the employment and well-being of people with disabilities. He co-directs the evaluation of SSA’s Benefit Offset National Demonstration and is a senior advisor to approximately 10 major projects for SSA, the Rehabilitation Services Administration, and the National Institute of Disability, Independent Living and Rehabilitation Research.
With more than 25 years of experience studying support programs for working-age people with disabilities, Stapleton regularly consults with federal and state officials about policy options to improve the economic well-being of these individuals and to reduce their reliance on Social Security Disability Insurance (SSDI), Supplemental Security Income, and other government programs. He has recently supported major efforts, organized by the Bipartisan Policy Center and the Committee for a Responsible Federal Budget, to develop proposals that address the pending exhaustion of the SSDI Trust Fund. He has testified on SSDI and employment issues before the Senate Finance Committee and the Social Security Subcommittee of the House Committee on Ways & Means. In addition, he has provided commentary to major media outlets such as The Hill, The Economist, National Public Radio, The Atlantic, and the Washington Post and the Wall Street Journal, and routinely presents at large research conferences hosted by the Association for Public Policy Analysis and Management and the American Economic Association. His research has been published in numerous academic journals and books.
Stapleton was formerly director of Cornell University’s Institute for Policy Research, senior vice president at the Lewin Group, and associate professor at both Dartmouth College and the University of Maryland, College Park. He has a Ph.D. in economics from the University of Wisconsin-Madison.
