It calibrates the impact each has on different wel- fare indicators and on the world’s income distribution. For personal income inequalities worldwide, the forces assuming first-order impor- tance are macroeconomic ones determining cross-country patterns of growth and convergence. The relation between a country’s growth performance and its inequality is insignificant in global inequality dynamics. The paper concludes that standard panel data economet- ric methods produce results misleading for the relation between in- equality and growth. Once this is t
