本文旨在量化德国累进养老金安排的福利效应。我们从纯供款相关的福利制度出发，引入供款的基本津贴和固定的福利比例。由于我们的重叠代模型考虑了可变劳动力供给、借贷约束和随机收入风险，我们可以比较政策改革的劳动力供给、流动性和保险效应。我们的模拟表明，对于一个现实的参数组合，养老金累进率的增加将产生超过2%的资源的总效率增益。然而，这样的改革不会得到实施，因为它不会得到当代人的政治支持。
The present paper aims to quantify the welfare effects of progressive pension arrangements in Germany. Starting from a purely contribution-related benefit system, we introduce basic allowances for contributions and a flat benefit fraction. Since our overlapping-generations model takes into account variable labor supply, borrowing constraints as well as stochastic income risk, we can compare the labor supply, the liquidity, and the insurance effects of the policy reform. Our simulations indicate that for a realistic parameter combination an increase in pension progressivity would yield an aggregate efficiency gain of more than 2 percent of resources. However, such a reform would not be implemented because it would not find political support of the currently living generations.
