Gender Gaps in STEM Occupations in Costa Rica, El Salvador and Mexico

This paper documents the existence of significant gender gaps in STEM occupations in Costa Rica, El Salvador, and Mexico and estimates the aggregate costs associated with these gaps in Mexico. For Mexico we calibrate and simulate a version of the general equilibrium occupational choice model of Hsieh et al. (2019) to estimate the output losses associated with these differences since 1992. We find that if barriers in STEM occupations were eliminated aggregate output would have been between 1% and 10% larger, depending on the year. If female-specific social norms were also eliminated, the rise in aggregate output would be between 1.4% and 14%. For comparison purposes, we also compute the gains of eliminating all the distortions in high-skilled occupations as well as in all occupations. We find that aggregate output would rise between 16.5% and 3.6% in the first case and between 36.7% and 12% in the latter.
