Algunos hechos estilizados y explicativos sobre el diferencial y la discriminación salarial por sexo en México, 1987-2015

This paper aims to analyze some stylized and explanatory facts about income differentials by monthly and hourly income in Mexico for the period 1987-2015. The explanatory power of human capital theory, synthesized in years of schooling, training and experience, is evaluated using the Blinder-Oaxaca methodology, which weighs the explanatory factors of endowments, full wage discrimination and factors not considered represented by the constants. The results show, in general, that the endowments of human capital have a temporary and partial effect, so that the trends of the hourly and monthly long-term earnings differentials are mainly explained by the behavior of wage discrimination and endowments of years of experience. Schooling as a factor of discrimination was relevant only for the period prior to the 1995 economic crisis and nafta, while the training factor has small and intermittent effects throughout the period of analysis.
