Wage inequality in the developing world: Evidence from Latin America by Carlos Rodríguez-Castelán, Luis Felipe López-Calva, Nora Lustig, Daniel Valderrama published by Review of Development Economics (7/2022).
We study the dynamics of wage inequality in Latin America in the past two decades. We find a consistent trend reversal in wage inequality in the region since the early 2000s: wage inequality fell across all countries in a way not predicted by the trends each country had experienced in the 1990s. The decline in wage inequality is explained by a disproportional expansion in the real hourly wage among low-paid workers, reducing both lower and upper tail inequality. About 40% of the observed reduction in wage variance was a response to the more equal wage structure, while the rest derived from a reduction in wage dispersion among workers with similar observable traits. The equalization of the wage structure in the 2000s is correlated with a reduction in the wage premium across education, experience, and place of residence. The reduction in the gender gap contributed, to a lesser extent, to the trend reversal.
