Does female management influence firm performance? Evidence from Luxembourg banks

In this study, we examine the relationship between the proportion of women in top management positions at banks and these institutions' financial performance. Using prudential data from supervisory reporting for all credit institutions in the Grand Duchy of Luxembourg from 1999 to 2013, we find a positive association between female management and firm performance. The economic effect is substantial: a 10% increase in women in top management positions improves the bank's future return on equity by more than 3% p.a. Moreover, we show that this positive relationship is (i) almost twice as large during the global financial crisis than in stable market conditions and (ii) non-linear, with banks having 20-40% female management being the most successful.
