This study estimates benefit-cost relationships for many subgroups of disabled persons, using regression analysis. The results sharply contradict the findings of a previous study, which suggested that low-productivity groups benefit as much, per dollar of expenditure, as do higher productivity groups. This study finds that, except for the variable of race, the relationship between rehabilitation outcome and variables such as age, sex, etc., are similar to the relationships often observed between these variables and labor market earnings of the general population. In short, high-productivity groups benefit most, per dollar of expenditure, from the provision of rehabilitation services.
