How Common is "Parking" Among Social Security Disability Insurance (SSDI) Beneficiaries? Evidence from the 1999 Change in the Level of Substantial Gainful Activity (SGA)
Jody Schimmel Hyde, David Stapleton and Jae Song
WP 2009-220

  • We estimate that 0.2 to 0.4 percent of disability beneficiaries "parked" their earnings below the $700 "substantial gainful activity" cap during 2002-2006.
  • Those who park keep earnings low in order to retain disability benefits.
  • The fraction of beneficiaries who park earnings is large relative to the number of individuals whose benefits are suspended because of work in a typical month (0.5 percent) or terminated in a typical year (0.5 percent).
