We explore how both dimensions of job inflexibility – from occupations and firms – impacts the Gender Wage Gap (GWG) in Brazil. If women demand more flexibility than men, maybe because of paid-work time competing with household chores and childcare, she could avoid working in inflexible occupations or firms with requirements of long hours of work. Also, women could be penalized in wages if she work less hours in occupations with high elasticities of wages in respect to total hours worked. Under the hypothesis that exporters require more hours worked and more commitment from their workers, as they are subjected to more competition in international markets, we explore how this possible shock to a firms job inflexibility affects the GWG when the worker s firm start exporting. We document a significant 18,6% increase in the GWG. This thesis also provide evidence of how occupational inflexibility impacts differentially women’s wages. Our results are consistent with a bigger GWG the more inflexible the occupation. However, this effect is less pronounced –and even reversed–for college educated workers. We hypothesize that this is due to richer women outsourcing household chores and childcare. Finally, we explore both dimensions of job inflexibility trough the analysis of how occupational inflexibility affects the GWG differently in exporting and non-exporting firms. The results are associated with the GWG in more inflexible occupations being bigger in exporting firms compared to non exporters.
