Age‐related Optimal Income Taxation*
研究了根据年龄调整所得税能否改善再分配机制，发现年龄依赖的所得税可以实现帕累托改进，并刻画了最优年龄依赖所得税的特征，其中利息税是结构的一部分。
Abstract In most countries, average income varies with age. In this paper we investigate if and how it is possible to enhance the redistributive mechanism by relating tax payments to age. Using an OLG model where some individuals are low skilled all their life while others are low skilled when young but high skilled when old, we first show how an age dependent optimal income tax can Pareto improve upon an age independent income tax. We then characterize the optimal age dependent income tax. A tax on interest income is part of the optimal tax structure.
