Pension Projection Models

PSG Models

Three stochastic microsimulation models &mdash SSASIM, PENSIM, GEMINI &mdash work together seamlessly to provide an easy-to-use, well-documented, fast-running, extensively-validated, publicly-available capability for U.S. pension and social security analysis. The combination of capabilities is unique.

Pension analysis capabilities focus on the implications of employer offerings, employee behavior, and government policy for the distribution of lifetime accumulations of employer-sponsored pension wealth and the resulting retirement incomes generated by pension wealth. Details

Social security analysis capabilities focus on the implications of government policy, demographic trends, economic conditions, and individual behavior for the solvency of the trust funds and for the distribution of benefits within and across birth cohorts. Details

Major Sponsors

The PSG models are sponsored in part by the following U.S. government agencies:
