我们在不平等和增长之间建立了一种新的理论联系。在我们的模型中，生育和教育决定是相互依赖的。贫穷的父母决定生很多孩子，而在教育上投资很少。收入分配中保持平均水平的差距增加了富人和穷人之间的生育率差距，这意味着教育程度低的家庭受到更多的重视。因此，不平等的加剧降低了平均教育水平，从而降低了增长率。我们发现，这种生育率差异效应解释了不平等与增长之间的大部分经验关系。
We develop a new theoretical link between inequality and growth. In our model, fertility and education decisions are interdependent. Poor parents decide to have many children and invest little in education. A mean-preserving spread in the income distribution increases the fertility differential between the rich and the poor, which implies that more weight gets placed on families who provide little education. Consequently, an increase in inequality lowers average education and, therefore, growth. We find that this fertility-differential effect accounts for most of the empirical relationship between inequality and growth.
