Changes in Wage Discrimination against People with Disabilities: 1984-93
利用1984和1993年收入与项目参与调查数据，分离健康影响后，发现残疾人的工资歧视在1984年仅占收入差距的3.7个百分点，且到1993年未减少，但健康对收入的负面影响显著下降。
A group of health-impaired workers who self-report in the Survey of Income and Program Participation that their productivity is not affected by their impairment is used to separately measure the effects of discrimination from the effects of poor health on earnings in 1984 and 1993. The results indicate that, in 1984, only 3.7 percentage points of the earnings gap is due to discrimination and the amount of discrimination did not decrease by 1993. Although discrimination did not change over the 1984 to 1993 period, the negative effects of poor health on the earnings of people with disabilities fell substantially.
