Is there regional convergence in the gender wage gap in Mexico?

The objective of the paper is to analyze the behavior of the gender wage gap, disaggregating formal and informal workers, and to contrast the existence of regional convergence, for the period 2005-2017 in Mexico. Applying the Oaxaca-Blinder methodology, wage gap measurements adjusted for composition effects are obtained and the existence of sigma and beta convergence among Mexican states is analyzed. The results provide evidence of sigma, beta and beta-conditional convergence. It is identified that the explained component plays a more relevant role in formal workers, while the unexplained part plays a more relevant role in informal workers.
