The Americans with Disabilities Act (ADA) provides civil rights protections
to persons with disabilities, but the debate that preceded passage of the
Act was not based on empirical estimates that could be used to measure its
performance. This article estimates the extent of wage discrimination again
st men with disabilities in 1990, providing a reference that can be used to
evaluate the impact of the ADA. The results show large productivity-standa
rdized wage differentials between disabled and nondisabled men that are wea
kly correlated with the strength of prejudice against different impairments
. Physical limitations explain part, but not all, of the wage differentials
. The results also show that low employment rates are a more serious proble
m than wage discrimination for workers with disabilities.
