Independent Project · Labor Market
Tests whether men and women earn the same pay for identical work across 150.8 million employment records. The answer is no: in the same role and city, women still earn 8% less.
Outcome
Within identical occupations and cities, controlling for background, women earn 8% less—a metric consistent across all three years analyzed. Neither hours nor hazard bonuses explain the gap, and across Brazil's 137 mesoregions, not one shows female wage superiority.
