Book excerpt: Supply-side Social Security reforms to increase employment and delay benefit claiming among older individuals may be frustrated by age discrimination. We test for policy complementarities between supply-side Social Security reforms and demand-side efforts to deter age discrimination, specifically studying whether stronger state-level age discrimination protections enhanced the impact of the increases in the Social Security Full Retirement Age (FRA) that occurred in the past decade. The evidence indicates that, for older individuals who were "caught" by the increase in the FRA, benefit claiming reductions and employment increases were sharper in states with stronger age discrimination protections.
