    This study analyzes how population changes and social security systems impact welfare in the US. It finds that retirement decisions significantly affect outcomes under both pay-as-you-go and actuarially-fair social security models.

    Area of Science:

    • Economics
    • Demography
    • Public Policy

    Background:

    • Demographic shifts, such as aging populations, present challenges to social security systems.
    • Social security policies are crucial for economic welfare, especially concerning retirement.
    • Endogenous retirement decisions complicate the analysis of social security's welfare implications.

    Purpose of the Study:

    • To examine the welfare effects of demographic changes interacting with social security in the United States.
    • To analyze the implications of endogenous retirement decisions within an overlapping generations model.
    • To compare welfare outcomes under pay-as-you-go and actuarially-fair social security systems.

    Main Methods:

    • Utilizing an overlapping generations (OLG) economic model.

  • Incorporating endogenous retirement behavior into the model.
  • Simulating and analyzing welfare implications under different demographic scenarios and social security structures.

    • Main Results:

    • Demographic changes significantly alter welfare outcomes under social security.
    • Endogenous retirement decisions lead to varied welfare impacts depending on the social security system design.
    • The pay-as-you-go system shows different sensitivities to demographic shifts compared to the actuarially-fair system.

    Conclusions:

    • The interaction between demographic trends and social security design critically influences societal welfare.
    • Policy design must account for endogenous retirement behavior to accurately assess social security's welfare impact.
    • Findings highlight the importance of robust social security frameworks in the face of demographic transitions in the US.
