Patrick Button (Tulane University), Mashfiqur Khan (Boston University), Do Stronger Employment Discrimination Protections Decrease Reliance on Social Security Disability Insurance? Evidence from the U.S. Social Security Reforms, Upjohn Inst. Working Paper 20-326 (2020):
The United States Social Security Amendments of 1983 (SSA1983) increased the full retirement age (FRA) and increased penalties for retiring before the FRA. This cut to retirement benefits caused spillover effects on Social Security Disability Insurance (SSDI) applications and receipt by making SSDI relatively more generous. We explore if stronger disability and age discrimination laws moderated these spillovers, using variation whereby many state laws are broader or stronger than federal law.
