This grant provides four years of renewed support to a postdoctoral fellowship program run by the National Bureau of Economic Research which supports talented young researchers interested in working on the economics of an aging workforce. Fellows receive a one-year stipend to carry out research at NBER’s office in Cambridge, Massachusetts, as well as limited funds for research-related purposes. In addition, fellows have the opportunity to participate in NBER’s weekly lunch seminars, NBER’s Summer Institute workshops on Aging and Labor Studies, relevant activities related to the larger NIA-NBER fellows program on Aging, and collaborative research and networking activities with a similar postdoctoral fellowship program at the Harvard Center for Population and Development Studies. Selection of the three fellows per year will be made by a panel of experts who are members of both the Aging and Labor Studies NBER programs. Nicole Maestas of Harvard University will chair the selection committee, which will include leading scholars in the fields of labor economics and the economics of aging. The committee’s decisions will be based on their evaluation of the fellows’ potential to make an important contribution to the understanding of the behavior of older workers and the functioning of labor markets for these workers.
