世代別積立方式に基づく公的年金制度への移行方法

抄録

In this paper, we propose transferring methods from the present pay-as-you-go scheme to a generation-based funding scheme. We make a mathematical model for the public pension system consisting of national pension, employee pension and mutual pension. Simulating the mathematical model the necessary government contribution is evaluated for the case with or without transferring to the generation-based funding scheme where we take into account the demographic structural change and the variation in economic situation.
