How are wages distributed globally? Wages do not follow a normal distribution, do they? Is wealth distributed in the same way or differently?
Globally, there is Lakner and Milanovik (2015)'s elephant graph:
Hellebrandt and Mauro (2015)
Thus, the two previous distributions look like bimodal log-normal distributions.
or CDFs, as in MacAskill's book Doing Good Better
Did not find something strictly related to wages. For most of people, income may be a good proxy of wages.
Both distributions are often modelled log-normal, with a substantial number of zeros. A pareto distribution is also sometimes used (Piketty & Saez (2012), p.32) for modelling the distribution of top incomes. Wealth distributions are also in general far more skewed than wage (or income) distributions.
