How Common is "Parking" among Social Security Disability Insurance Beneficiaries? Evidence from the 1999 Change in the Earnings Level of Substantial Gainful Activity
The authors explore the extent to which Social Security Disability Insurance (DI) beneficiaries restrain their earnings below the substantial gainful activity (SGA) level in order to maintain their cash benefits. The extent of "parking" is measured by exploiting the 1999 change in the nonblind SGA earnings level from $500 to $700 and assessing its effect on cohorts of DI beneficiaries who completed their trial work period, one of which was affected by the SGA change, and one that was not.
The authors use longitudinal Social Security administrative data to produce statistics on the number of Disability Insurance (DI) and Supplemental Security Income (SSI)-only beneficiaries whose cash benefits were first suspended or terminated because of work and on the number of months thereafter that those beneficiaries remained in nonpayment status before their return to the program rolls, attainment of the full retirement age, or death—for each year from 2002 through 2006. We also explore differences by program title (DI versus SSI-only) and by participation in the Ticket to Work program. Finally, we examine outcome payments made on behalf of Ticket to Work participants in months of nonpayment status following suspension or termination because of work.
