In their new study, "The Wealth Inequality of Nations," appearing in the August 2021 issue of the American Sociological Review, authors Fabian T. Pfeffer and Nora Waitkus show that comparing countries in terms of their wealth inequality instead of income inequality provides a fundamentally different picture of nations' relative level of economic inequality.
