经济增长与宏观政策选择——基于含人力资本增长模型的动态优化分析

Abstract

本文扩展Rebelo的含人力资本经济增长模型,将其导入内生性政府部门,建立了具一般性的混合经济内生增长模型,以探讨混合经济中的政府最优政策选择。分析表明,不论国营教育体制还是民营教育体制,政府可以通过适当的政策选择引导经济达到社会性最优增长状态。我们导出了关于征税和财政补贴的最优性条件并探讨了它们的政策含意。This paper extends the endogenous growth model with human capital given by Rebelo ( 1990) to construct a g eneral growth model o f the mixed economy of on going growth。 Such a model is appropriate for the analysis of optimal government policies in the modern mixed economy。We show that the government is capable of leading the mixed economy to the social optimum, no matter whether the education is provided by the private sector or by the g overnment。We also derive the taxation conditions for the social optimum and discuss their policy implications。
