Branko Milanovic presents an analysis using microdata from 25 Western economies. The study converts all household incomes into the same currency using purchasing power parity (PPP dollars) and expresses them in real terms, treating the group as a single country.
Milanovic shares a resulting Growth Incidence Curve based on this pooled dataset, illustrating income distribution trends for the period referenced.
Milanovic’s approach to examining income convergence across Western economies invites comparison to historical benchmarks for national wealth. Notably, his evaluation of aggregate prosperity aligns with earlier findings on how U.S. GDP per capita reached a peak in 1952, marking a pivotal moment in the country’s economic standing relative to the rest of the world.
