HOW THE GROWING GAP IN LIFE EXPECTANCY MAY AFFECT RETIREMENT BENEFITS AND REFORMS

Area of Science:

• Health Economics
• Gerontology
• Public Policy

Background:

• Recent decades show significant increases in life expectancy for older Americans.
• However, these gains disproportionately benefit higher-income individuals.
• This trend raises concerns about equitable access to resources and program benefits.

Purpose of the Study:

• To analyze how increasing life expectancy inequality affects lifetime benefits from Social Security and Medicare.
• To investigate the interaction between life expectancy disparities and potential program reforms.
• To quantify the financial implications of diverging longevity across income groups.

Main Methods:

• Projected life expectancy at age 50 for different income quintiles across birth cohorts (1930-1960).
• Calculated the widening gap in average lifetime program benefits between highest and lowest income quintiles.
• Simulated the impact of Social Security reforms (e.g., raising retirement age, altering benefit formulas).

Main Results:

• Life expectancy at age 50 for males in the top two income quintiles is projected to increase by 7-8 years between the 1930 and 1960 birth cohorts.
• The two lowest income quintiles are expected to experience minimal to no increase in life expectancy.
• The difference in average lifetime benefits from programs like Social Security and Medicare between the highest and lowest income quintiles is projected to widen by $130,000 (in 2009 dollars).

Conclusions:

• Growing inequality in life expectancy exacerbates disparities in lifetime program benefits.
• Proposed Social Security reforms may have varying effects on mitigating or enhancing this reduced progressivity.
• Addressing life expectancy gaps is crucial for ensuring equitable outcomes in social insurance programs.
