We found that firms with a high degree of internationalization (measured as the percentage of firm revenues from international operations) have fewer women in management. When firms are dependent on foreign operations for their survival, and when foreign countries express prejudices when interacting with women, employers may not see value in hiring and promoting women and deploying them abroad. The gender biases in certain foreign countries may explain why women are less likely to be sent overseas on international assignments. In other words, when women are not considered to be a critical resource to a firm, they are less likely to be promoted. This, in turn, limits women’s advancement into senior management, because they often require international experience as a skill set necessary for leadership roles.
