Gender diversity in top-management positions in large family and nonfamily businesses

(Why) does the sex ratio in top-management positions in large family and nonfamily businesses differ? Using a unique data set and estimating (fractional) logit regressions we show that the female share in top-management positions in family businesses exceeds the one in nonfamily businesses. One reason is the selection mechanism social homophily from which females in family businesses benefit more because of a higher female share in the decision making body in family businesses. Another reason is the pathway self-appointment as (co-) leader of one's own business which is more common in family businesses. Nepotism seems not to play a role.
