The Negative Effects of Public Benefits on Individual Employment: A Multilevel Analysis of Work Hours.

Nord et al. (2015) looked at a big state vocational-rehab database. They asked: do adults with intellectual or developmental disabilities work fewer hours if they also get public benefits?

The team used a quasi-experimental design. They tracked weekly work hours while people kept or lost benefits like SSI or Medicaid.

People who kept public benefits worked fewer hours each week. Their hours also grew more slowly over time.

The link stayed strong even after the authors controlled for age, job type, and state.

Sannicandro et al. (2018) seems to disagree. They found that adults with ID who finished college worked more and earned more. The difference is the lever: college boosts work, while benefit rules may cap it.

Steege et al. (1989) and Hall (2010) show supported employment pays back most of its cost. Derek et al. add a warning: benefit cliffs can undo those gains by punishing extra hours.

Dai et al. (2023) review shows this kind of large-dataset study is one of the few ways to spot systemic barriers. The 2015 paper is now a go-to example in that review.

If you write employment goals, check each client’s benefit plan. A few extra hours can trigger a cash cliff and stall progress. Build in safeguards: use benefits counseling, gradual hour ramps, or special work incentives so work always pays more than it costs.
