From life course theory individuals’ roles in society vary over their life stages. Such roles are gendered to the extent that institutions in society differentially constrain opportunities and differentially assign roles and role expectations to men and women during their life courses. In this study, we explore how different levels of gender-egalitarianism cause different patterns in men’s and women’s engagement in opportunity driven entrepreneurship relative to their age. The analysis based on unique data suggests that women’s response to increasing gender egalitarianism is equal across life stages while men’s response is highly age-graded.
