In this report we analyze board diversity and its impact on corporate performance. We investigate the 500 largest companies from Denmark, Norway, and Sweden. This report reveals that Scandinavian boards are surprisingly homogenous in terms of gender and nationality, whereas the age distribution is more diverse. The low level of board diversity in terms of gender and nationality in the Scandinavian countries seems puzzling given the participation of women in the workforce and the internationalization of the work force of Nordic firms.
