Evidence based on US firms suggests that large boards restrain risk taking. We investigate whether a similar effect exists in Japan. Our results confirm that firms with larger boards exhibit lower performance variability relative to firms with smaller boards. However, this effect is less...

Foreign investors have in recent years increased their ownership of Japanese firms. Has this greater involvement contributed to improve firm performance? We show that the answer depends on the assumptions regarding the unobservable firm effects. If the latter are assumed to be time invariant, as...

We analyze the role of board age on firm performance using a large sample of Japanese firms. The results reveal the existence of a significant negative relationship. After controlling for endogeneity using firm size as instrument, the effect of board age is found to be more significant,...

We show that large boards are detrimental to the performance of Japanese firms. Unlike in the US, this effect is concealed by the fact that Japanese firms that have performed well are more likely to increase the size of their boards. Using an instrumental variable approach to address this...
