David Mann’s research interests include the labor force participation, human capital accumulation, and benefit receipt of youth and adults with disabilities. He also has expertise in disability policy reform.
Mann has played a key role in projects examining employment and benefit receipt for people with disabilities, especially vocational rehabilitation customers, Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) beneficiaries, and young adults with childhood onset disabilities. He has helped develop and evaluate Social Security Administration initiatives that promote employment for SSI and SSDI beneficiaries, including Ticket to Work, the Benefit Offset National Demonstration, and the Work Incentive Simplification Pilot. Mann helps oversee Mathematica’s work for two Rehabilitation Research and Training Centers, which are funded by the National Institute on Disability, Independent Living, and Rehabilitation Research to produce new knowledge that can improve the well-being of people with disabilities. He was principal investigator in disability employment policy for the U.S. Department of Labor’s Clearinghouse for Labor Evaluation and Research, which is improving the accessibility of research evidence for policymakers and stakeholders.
Mann, who joined Mathematica in 2011, publishes in peer-reviewed publications such as the Journal of Human Capital, the IZA Journal of Labor Policy, the Journal of Disability Policy Studies, and the Social Security Bulletin. He has co-authored papers on approaches for reforming the nation’s disability support system to achieve fiscal objectives and improve outcomes for people with disabilities. He holds a Ph.D. in economics from the University of Pennsylvania.
