Abstract

This paper studies recent inequality patterns and the distributional effects of schooling and job informality on wage inequality in Argentina, Brazil, Colombia and Mexico during the 2002–2014 period. By means of a quantile regression framework, we decompose changes in the wage gap using several techniques including the Machado and Mata algorithm, the RIF regression unconditional quantile regression method and the random-coefficients quantile regression representation. Results show that the reduction in wage inequality is explained by the improvements in the lower part of the wage distribution in which the pricing rather than the composition effect explains most of the changes. We found that the composition effect of education was unequalizing, while their pricing effect was inequality reducing. Job formality favored relatively more workers in the lower part of the distribution and had an important pricing effect below the median for all countries, but only in the 2002–2008 period.
