The dynamics of population growth differential fertility and inequality.
分析生育率收入差异对洛伦兹曲线和标准不平等指标的影响，利用巴西数据模拟发现消除生育率差异后两个不平等指标在稳态和过渡期反向变动，证实差异化生育率会导致跨期不平等比较产生误导。
This paper analyzes the effects of income differentials in fertility on Lorenz curves and standard inequality measures. The role of intergenerational mobility is examined and incorporated into counterfactual simulations based on Brazilian data. Two standard inequality measures move in opposite directions in both the steady state and the transition in response to the elimination of fertility differentials. The counterfactuals confirm the theoretical predictions of misleading intertemporal inequality comparisons in the presence of differential fertility. Copyright 1986 by American Economic Association.
