Human Capital Inequality, Life Expectancy and Economic Growth
构建模型，研究不平等如何通过影响个体教育投资决策（受父母人力资本决定的预期寿命影响）作用于人均收入，发现存在多重稳态，低稳态为贫困陷阱，实证表明预期寿命机制解释了不平等与人力资本积累间的主要关系。
This paper presents a model in which inequality affects per capita income when individuals decide to invest in education taking into account their life expectancy, which depends to a large extent on the human capital of their parents. Our results show the existence of multiple steady states depending on the initial distribution of education. The low steady state is a poverty trap in which children raised in poor families have low life expectancy and work as non-educated workers. The empirical evidence suggests that the life expectancy mechanism explains a major part of the relationship between inequality and human capital accumulation.
