Sources and notes O Source: author's elaborations based on data Piketty, Thomas and Saez,
Emmanuel (2007). Income and Wage Inequality in the United States 1913-2002; in Atkinson, A. B. and Piketty, T. (editors) Top Incomes over the Twentieth Century. A Contrast Between Continental European and English-Speaking Countries, Oxford University Press, chapter 5. Series updated by the same authors.
O Data available on: http://topincomes.g-mond.parisschoolofeconomics.eu/ O The Pareto-Lorenz coefficients were computed using the top shares estimates.
As a rule they were estimated from the top 0.1% share within the top 1% share: a=1/[1-log(S1%/S0.1%)/log(10)].
