Growth with Optimal Taxation and Public Spending Composition

经济增长中的最优税收与公共支出结构(英文)

BarroChamley, , , , : Incorporating endogenous public spending, the basic characteristic of the Barro model, into the Chamley model, this paper discusses the optimal taxation and public spending composition in economic growth. The two-stage backward induction method is adopted to explore the general optimality (including the first and second best) conditions for taxation and public spending, and the explicit solutions to optimal taxation and public spending composition are showed in a specific example. Finally, we estimate China’s optimal level of macro tax burden with the help of numerical calculation.View full textDownload full text

本文将Barro模型关于内生公共支出的基本特征引入Chamley模型,考察了经济增长中的最优税收与公共支出结构问题。利用两阶段逆向归纳法,分别探讨了社会第一优和次优的税收与公共支出结构的一般条件,并通过一个具体例子给出了最优公共支出与税收的显示路径。最后通过数值计算,对中国的最优宏观税负水平进行了估计。
