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 the 80% of the global output and the 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 capitalization process, and China is the main responsible of this global trend. The findings of this paper are robust to changes in the income definition, and top-income adjustments. The global composition of capital and labor incomes is, therefore, more equal today than it was twenty years ago.
