在最近对公共养老金制度理论的贡献中，有人认为，从一个既定的无基金养老金制度向一个有基金养老金制度的帕累托改进过渡是可能的。这一结果是在具有相同个体的世代交替模型中得出的。在本研究中，一个扩展的模型，不同的个人，一代人内公平的无基金养老金计划的介绍。在这个更现实的框架内，它表明，在一般情况下，帕累托改善过渡到一个供资系统是不可能的，因为任何工具适用于在过渡阶段的养老金融资涉及代内再分配。
In recent contributions to the theory of public pension systems it was argued that a Pareto-improving transition from an established unfunded pension system to a funded one is possible. This result is derived in an overlapping-generations model with identical individuals. In the present study an extended model, with differing individuals, of an intragenerationally fair unfunded pension scheme is introduced. Within this more realistic framework it is shown that, in general, a Pareto-improving transition to a funded system is not possible because any instrument applied to the financing of pensions in the transition phase involves intragenerational redistribution.
