This article investigates whether exchanging Social Security delayed retirement credits, currently paid as increases in lifelong benefits, for a lump sum would induce later claiming and additional work. We show that people would voluntarily claim about 6 months later if the lump sum were paid for claiming after the early retirement age, and about 8 months later if the lump sum were paid only for those claiming after their full retirement age. Overall, people will work one-third to one-half of the additional months. Those who would currently claim at the youngest ages are most responsive to the lump sum offer.
