Funds from this grant provide continued support to the National Bureau of Economic Research (NBER) in its efforts to lead a network of top economists in the examination of issues related to aging and work and to the barriers to working longer. Led by economist David Wise, this network of scholars has substantial past and ongoing research expertise on health and health trends at older ages, population aging and its implications, the determinants of work and retirement, the incentives in public and employer policies, and the psychosocial factors that influence behavior. Grant funds will help NBER extend the network collaboration by producing at least nine papers focused on how to facilitate work at older ages. Additional topic areas to be addressed include work capacity at older ages; how public and employer benefit policies affect work and retirement; and factors that facilitate work by seniors, such as work environments and job flexibility.
