Explaining International and Intertemporal Variations in Income Inequality
利用新数据集验证了收入不平等在国家内部相对稳定、国家间差异显著的命题，并发现公民自由、初始中学教育、金融深度和初始土地分配是重要决定因素。
This paper explores the propositions that, income inequality is relatively stable within countries; and that it varies significantly among countries. A new and expanded data set provides broad support for both propositions. Drawing on a political economy and capital market imperfection arguments to explain the intertemporal and international variation in inequality, the empirical analysis shows that the predicted variables associated with the first argument (a measure of civil liberties and the initial level of secondary schooling) and the second argument (a measure of financial depth and the initial distribution of land) are indeed important determinants of inequality.
