[영문]The authors examine how benefit amounts and family income would change in response to changing the Social Security (Old-Age, Survivors, and Disability Insurance, OASDI) benefit indexing scheme. In this article, the authors focus on the distributional effects on the disabled. The analysis uses a cross-sectional sample of OASDI beneficiaries from the 1996 Survey of Income and Program Participation matched to Social Security administrative records. Specifically, the cross-sectional estimates suggest that the average change in OASDI benefit levels would be higher for disabled-worker beneficiaries than for retired-worker beneficiaries. The estimated effects of changing the indexing scheme are further muted when total family income is considered. This occurs on a roughly equivalent scale for disabled and retired workers. Finally, the authors examine the most economically vulnerable subgroups of OASDI beneficiaries. Within the general group of beneficiaries, they find that the most vulnerable would be less affected than average, primarily as a result of the mitigating effect of Supplemental Security Income benefits.
