Summary
Stapleton and Martin (2012) use matched Rehabilitation Services Administration (RSA) 911 vocational rehabilitation (VR) closure records (1998–2009) linked to the Social Security Administration's (SSA) Ticket Research File (TRF), Master Earnings File (MEF), and Numident to document how many VR applicants enter Social Security Disability (SSD) in the 60 months following application — the first study to do so. The 2002 cohort (N=480,566) shows 17.8% entered SSD within 60 months, with Supplemental Security Income (SSI) recipients at VR application being the single strongest predictor (94% SSD entry). The paper shows that institutional incentives in the SSA cost-reimbursement payment system may perversely encourage VR agencies to accelerate, rather than prevent, SSD entry. The causal effect of VR service delivery on SSD entry is theoretically ambiguous and empirically unidentified.
Key Claims
- One in six VR applicants enters SSD within 5 years: For the 2002 cohort, 5.5% were already on SSD at VR application, rising to 10.3% at closure and 17.8% at 60 months. For the 2003 cohort, 11.3% (50,000+) entered SSD after application.
- SSI status is the dominant predictor: 94% of SSI recipients at VR application entered SSD within 60 months, versus 14.5% of non-SSI applicants. The mechanism: SSI recipients already meet SSD medical eligibility and need only become disability-insured via work; VR services help them earn enough quarters of coverage without engaging in substantial gainful activity (SGA).
- Older and more educated applicants have higher SSD entry rates: Age 50–59 applicants: 32.2% at 60 months. Bachelor's degree holders: 26.2% — counterintuitively higher than dropouts (11.7%), explained by greater disability-insured status (more work history → more quarters of coverage).
- Wide state variation: 60-month SSD entry ranges from ~15% (UT, SC, DC, Puerto Rico) to ~30% (ME, MA, NH) — roughly 2:1 ratio unexplained by observable applicant characteristics.
- Perverse institutional incentives: SSA's cost-reimbursement system pays VR agencies when SSD clients engage in SGA for 9 months. This incentivizes agencies to help non-insured clients become disability-insured (to qualify for SSA payment) rather than preventing SSD entry. States also benefit fiscally by shifting Medicaid clients to Medicare (federal-only). Current policy may systematically accelerate SSD entry among VR clients.
- Theoretical ambiguity: VR services may reduce SSD entry (helping capable clients engage in SGA) or increase it (helping marginally employable clients understand eligibility, become insured, and enter SSD). Direction is client-dependent; net effect is unknown.
- Positive but confounded wait-time gradient: VR applicants with longer waits to their Individualized Plan for Employment (IPE) have higher 60-month SSD entry (14.3% for 37+ months vs. 11.9% for <3 months). This likely reflects selection and business cycle confounding, not a causal effect of wait time.
- Fiscal stakes are large: A 10,000-person shift in annual SSD decisions implies ~$1.7B/year in SSD + Medicare expenditures — comparable to the $3.1B federal VR budget. Impact could be in either direction.
- Data: RSA 911 + SSA TRF/MEF/Numident. N=3,656,105 unique new VR applicants 1998–2005; 480,566 in 2002 focus cohort.

Quotes
"VR services might accelerate the client's entry into SSD, perhaps by helping the client understand SSD rules and obtain a job that does not represent SGA."
"The state has a financial incentive to help the client obtain Medicare. The state pays a share of Medicaid expenditures, whereas Medicare is funded entirely by the federal government."
My Take
The paper's core descriptive finding — ~1 in 6 VR applicants enters SSD within 5 years, with SSI recipients at near-certain risk — is policy-relevant and actionable. The institutional incentive analysis is particularly insightful: the SSA cost-reimbursement structure and state Medicaid-to-Medicare fiscal incentives create a situation where VR agencies rationally accelerate SSD entry rather than preventing it. This is a systemic design flaw, not a behavioral failure. The causal question (do VR services cause more or less SSD entry?) remains open; the proposed instrumental variable (IV) (state-month duration percentile) is creative but the authors correctly acknowledge business cycle confounding as a serious threat. As a descriptive study, it is highly reliable — the statistics are population-level administrative data counts, not estimates. The main limitation is the absence of a comparison group to assess counterfactual SSD entry absent VR services.
