A Closer Look at the Employment Impact of the Americans with Disabilities Act
复现了《美国残疾人法案》实施后残疾人就业下降的发现，并指出下降源于劳动力参与率降低，而非就业概率恶化，可能是非残疾非参与者被重新分类为残疾所致。
Abstract This paper replicates recent findings that employment among disabled people has declined since the ADA. A closer look indicates that this decline results from a drop in the labor force participation rate among those classified as disabled. Further analysis indicates that this labor force participation rate decline, however, was not the result of disabled individuals fleeing the labor market, but, rather, more likely a result of the reclassification of nondisabled, nonparticipants, as disabled. The unconditional employment probability among disabled people (taking selection into the labor market into account) has not declined, and may have actually improved for certain disability classifications.
