Global distributions of capital and labor incomes: capitalization of the global middle class

This article studies the global distributions of capital and labor incomes among individuals in 2000 and 2016. By constructing a novel database covering approximately 80% of the global output and 60% of the world population, two major findings stand out. First, the world underwent an important process of capitalization. The share of world individuals with positive capital income rose from 20% to 32%. Second, the global middle class benefited the most, in relative terms, from such a capitalization process, with China being the main driver of this global trend. The findings of this paper are robust to changes in the income definition, top-income and functional income distribution adjustments. The global composition of capital and labor incomes is more equal today than it was twenty years ago.
