Increasing older people's employment rates could reduce the economic pressures of an aging population, and many older adults say they want to delay retirement. Yet, numerous public policies and private practices continue to encourage early retirement. The Urban Institute, with support from the Alfred P. Sloan Foundation, sponsored an October 2007 roundtable to examine the value of older adults' work. Researchers, practitioners, employers, and policymakers discussed the potential supply of and demand for older workers, the benefits of working longer, barriers to continued employment, and policy solutions to encourage work at older ages. This document summarizes the issues and discussion.
