Book excerpt: For over a decade, the National Bureau of Economic Research has sponsored the Economics of Aging Program, under the direction of David A. Wise. The program addresses issues that affect the well-being of individuals as they age and a society that is composed increasingly of older people. Within the next twenty years, an unprecedented proportion of Americans will be over sixty-five. New research in the economics of aging is an essential element of understanding what the future holds for this aging population. Inquiries in the Economics of Aging presents both empirical papers that consider questions that are fundamental to public policy and more theoretical contributions that lay new groundwork for future research in the economics of aging. Inquiries in the Economics of Aging provides a timely overview of some of the most important questions facing researchers on aging and outlines new techniques and models that may help to answer these questions. This important volume will be of great interest to specialists and policy makers as it paves the way for future analysis.
