New research from PSC ressearcher, Olivia S. Mitchell, a Wharton professor of business economics and public policy, attempts to answer these questions. The paper, “Evaluating Lump Sum Incentives for Delayed Social Security Claiming,” was co-authored with Raimond Maurer, a finance professor at Goethe University in Frankfurt, Germany. Mitchell, who also serves as director of Wharton’s Pension Research Council, recently appeared on the Knowledge@Wharton radio show on SiriusXM to discuss their findings.
