Capital Shares and Income Inequality: Evidence from the Long Run
利用新构建的历史跨国数据库，研究国民收入中资本份额与顶层个人收入份额之间的长期关系，发现两者存在强正相关且随时间增强，对理解收入不平等有参考价值。
This article studies the long-run relationship between the capital share in national income and top personal income shares. Using a newly constructed historical cross-country database on capital shares and top income data, we find evidence on a strong, positive link that has grown stronger over the past century. The connection is stronger in Anglo-Saxon countries, in the very top of the distribution, when top capital incomes predominate, when using distributed top national income shares, and when considering gross of depreciation capital shares. Out of-sample predictions of top shares using capital shares indicates several cases of over- or underestimation.
