Project Scope

This study builds on the report of the first study phase Aging and the Macroeconomy: Long-term Implications of an Older Population.  This report, which was published in December 2012, summarized what is known about how factors such as savings rates, stock market exposure, productivity, consumption patterns, and global capital flows react to demographic shifts.

For the Phase II of the study, an ad hoc committee will help clarify the long-term macroeconomic effects of population aging in the United States. This phase will incorporate quantitative modeling and projections in order to develop new insights about the long-run macroeconomic effects of the aging U.S. population. The primary focus of the study will be on the implications of increases in the spread of population distributions of income and longevity for age-related public programs and for the reform of these programs to meet the challenges presented by an aging population.
Phase II of the study shall include, but will not be limited to, the following elements:

  • Evaluation of long-term trends in the share of national output devoted to support of the elderly population.
  • Documentation and exploration of the underlying causes of the growing gaps in income and life expectancy in the United States.
  • Examination of how the growing gaps in income and life expectancy affect national public programs such as Social Security, Medicare and Medicaid, and how these gaps interact with proposed policy adjustments to achieve sustainability in the context of population aging.
  • Construction of generational accounts by lifetime income or education for different population cohorts under different policy regimes.

This project is sponsored by the U.S. Department of Treasury. The approximate start date for this project is September 29, 2012. The Phase II report will be issued at the end of this project in approximately 24 months.
