Globalizing Inequality: ‘Centrifugal’ and ‘Centripetal’ Forces at Work

This paper reassesses national income inequalities in this era of globalization. The main conclusion is that two opposite forces are at work: one ‘centrifugal’ at the two extremes of the distribution—increasing the disparity of income shares appropriated by the top and by the bottom four deciles across countries; and the other ‘centripetal’ in the middle—increasing the uniformity of the share of income going to deciles 5 to 9. Therefore, globalization is creating a situation where virtually all the intercountry diversity of income distribution is the result of differences in what the rich and the poor get in each country.
