The next two decades will mark a new phase in the demographic transition of the United States as baby boomers become eligible for Social Security and Medicare. Drawing on evidence from the United States and other nations, "Explorations in the Economics of Aging" yields important new findings on how economic decisions by households and policy choices by governments will influence the effects of this demographic shift. It explores topics such as the implications of differential mortality rates by income on Social Security, the link between cognition and economic outcomes, and scale variations in self-reported work disability. This volume will be an important reference for economists and policymakers alike.
