NBER Reporter Summary - 2014 Number 2

Core Content

The NBER Reporter for 2014 Number 2 provides an overview of the Program on the Economics of Aging, highlighting its role in studying the financial and health well-being of older populations, as well as the broader implications of demographic changes in the United States. The report also includes summaries of recent NBER research on labor market adjustment to trade, gender identity, taxes and talent mobility, and the financialization of commodity markets. Additionally, it outlines the structure and leadership of the NBER, its funding sources, and ongoing research initiatives.

Main Topics and Research Summaries

1. Economics of Aging

• Program Overview:

  • The NBER's Program on the Economics of Aging was established in 1986.
  • It focuses on the health and financial well-being of older people and the broader economic implications of an aging population.
  • The program has evolved from an emerging research area into a well-recognized and influential subfield of economics.

• Key Trends:

  • Demographic Shift: The aging of the baby boomer generation is a major societal challenge.
  • Retirement Policies: There is a shift from employer-provided pensions (DB) to individual retirement savings plans like 401(k)s.
  • Health and Longevity: Increasing life expectancy and improvements in health outcomes are reshaping the labor market and financial planning for older adults.
  • Policy Impact: Public programs such as Social Security, Medicare, and Medicaid are critical to older people's well-being, and their structure significantly influences retirement behavior and financial security.

• Research Focus:

  • Financial Well-Being: Studies analyze how people save, invest, and use their retirement assets, with a focus on the role of default options, behavioral nudges, and financial literacy.
  • Health Outcomes: Research explores the relationship between health, longevity, and economic productivity, including the impact of public health policies and insurance coverage.
  • Work and Retirement: The program investigates how public policies and work environments affect the decision of older workers to continue working or retire.

Key Research Findings

Financial Well-Being

• Saving Behavior:

  • Automatic enrollment in retirement plans is more effective in encouraging saving than financial incentives.
  • Simplified information and peer influences can increase participation in retirement savings.
  • Financial literacy is a critical factor, with many individuals lacking the knowledge to make informed decisions about their retirement savings.

• Investment Decisions:

  • Defaults in investment options significantly influence portfolio allocation.
  • Target-date funds and other automated investment tools are being studied for their impact on retirement planning.
  • Annuity purchases are less common in the private market, but they can provide a stable income stream for older adults.

• Public Policy Impact:

  • The Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) reduce benefits for certain retirees, particularly those with lower lifetime earnings.
  • Research shows that public pension data may be understated in some surveys.

Health and Life Satisfaction

• Health and Longevity:

  • There is evidence of compression of morbidity, where older people are living longer but with fewer years of disability.
  • Health indicators are being aggregated to better understand overall health trends and their economic implications.

• Health Policy Impact:

  • Expanding health insurance coverage leads to increased healthcare utilization and improved health outcomes.
  • Health reforms in Massachusetts have resulted in lower premiums and better health outcomes.

• Behavioral Health Interventions:

  • Studies show that planning prompts can increase adherence to medical appointments and vaccination rates.
  • Research on anemia treatment using fortified salt highlights the potential of public health interventions.

• Well-Being Beyond Health:

  • Researchers are examining non-traditional measures of well-being, such as happiness, life satisfaction, and social relationships.
  • The "new science of pleasure" and the impact of living arrangements on life satisfaction are also being explored.

Work and Retirement at Older Ages

• Labor Force Participation:

  • Public policies, particularly disability insurance (DI) provisions, significantly influence the labor force participation of older workers.
  • Research suggests that health improvements have enabled older people to work longer, though this is affected by policy structures.

• Cross-Country Analysis:

  • A global study on Social Security and retirement involves researchers from multiple countries.
  • The role of DI programs in determining labor force participation is a key focus.

NBER Overview

• Mission and Structure:

  • The NBER is a private, nonprofit research organization established in 1920.
  • It is led by James M. Poterba as President and CEO, with a board of directors including prominent economists and scholars.

• Funding:

  • The NBER relies on funding from individuals, corporations, and private foundations.
  • It receives significant support from the National Institute on Aging (NIA) and the Social Security Administration (SSA).

• Research Output:

  • The NBER publishes Working Papers and Research Volumes on aging.
  • Notable volumes include Research Findings in the Economics of Aging (2010), Explorations in the Economics of Aging (2011), and Discoveries in the Economics of Aging (2014).

• Training and Development:

  • The NBER has supported over 150 investigators through its training programs.
  • John Bates Clark Medal recipients like Esther Duflo, Amy Finkelstein, and Raj Chetty have been active in the Aging Program.
  • The program has also been instrumental in developing new research directions in economics.

Conclusion

The NBER's Program on the Economics of Aging plays a vital role in understanding the financial and health implications of an aging population. It has fostered a multidisciplinary approach to aging research, influencing public policy and improving the well-being of older adults. The program continues to evolve, with ongoing studies on retirement savings, health outcomes, and work behavior, all of which are essential for addressing the challenges of an aging society.
