Interdependencies of female board member appointments

We investigate the appointments of female board members of Japanese corporations together with the corporations’ performance. We relate the presence of female board members to the board and ownership networks of the corresponding firms. We find that firms with female board members often show above average performance. We also find that corporate boards and the corresponding members show homophily with respect to gender in their networks. The observed homophily leads to interdependencies in the appointments of new board members. New appointments of female board members are more likely at firms with ties to other boards with female board members.
