本文分析了人力资本积累外部性的一般均衡模型的动态性，并分析了禀赋冲击对短期和长期产出水平的影响。对于某些参数值，自我实现的期望和埃克斯特- nalities产生一个连续的均衡。一般来说，积极的捐赠冲击之后可能会出现增长率的上升或下降。一个简单的条件是建立了一个积极的影响，实物资本的产出水平在长期。在满足结构参数合理值的相同条件下，一次总付税的效率低于某些资本所得税。
This paper analyzes the dynamics of general equilibrium models with ex- ternalities in human capital accumulation and measures analytically the impact of endowment shocks on the levels of output in the short- and the long-run. For some parameter values, self-fullfilling expectations and exter- nalities generate a continuum of equilibria. In general, positive endowment shocks can be followed by higher or lower growth rates. A simple condition is established for a positive impact of physical capital on the level of output in the long-term. Under the same condition which is satisfied for plausible values of the structural parameters, lump-sum taxa- tion is less efficient than some capital income taxation.
