Public Pensions and Retirement: Evidence from the Railroad Retirement Act

Area of Science:

• Economics
• Public Policy
• Labor Economics

Background:

• Private railroad pensions were replaced by the Railroad Retirement Act of 1937, a national program similar to Social Security.
• Understanding the impact of public pensions on retirement decisions is crucial for policy-making.

Purpose of the Study:

• To estimate the effect of public pension generosity on retirement timing.
• To analyze the retirement response to the Railroad Retirement Act of 1937 and its implications for Social Security.

Main Methods:

• Utilized linked decennial census records from 1910-1940.
• Compared male labor force nonparticipation rates before and after the pension changes.
• Employed a difference-in-differences approach and exploited benefit structure changes to estimate elasticity.

Main Results:

• Higher pension benefits were associated with earlier retirement, especially at age 65.
• The estimated elasticity of nonparticipation with respect to benefits for men aged 65-69 was 0.55, indicating a substantial retirement response.
• Rising Social Security benefits in the 1950s likely drove earlier retirement among the insured male population.

Conclusions:

• Public pension programs, like the Railroad Retirement Act, have a significant impact on individuals' retirement decisions.
• The design of pension benefits, particularly their generosity, is a key determinant of retirement timing.
• Findings provide insights into the effects of Social Security expansions on labor force participation.
