SOCIAL SECURITY AND RETIREES’ DECISION TO WORK

Abstract

Non-linearities in the Social Security benefits formula are used to estimate the effect of benefit size on the probability married beneficiaries work after initiating benefits. Consistent with economic theory, benefit size has a significant, negative effect on the probability of post-retirement work. A 10% increase in benefit size decreases the probability of work 3-4 percentage points for recently retired husbands (from a mean of 25.5%) and 2-3 percentage points for recently retired wives (from a mean of 12.8%). For both spouses, the effect erodes in later years of retirement.Social Security, retirement, labor supply
