In a large sample of European firms we analyze the value discount associated with disproportional ownership structures first documented by Claessens et al. (2002). Consistent with a theoretical model of incentive and entrenchment effects, we find higher value discount in family firms, in firms with low cash flow concentration, and in industries with higher amenity value. Furthermore, the discount is higher in countries with good investor protection and higher for dual class shares than for pyramids. We find no impact on operating performance, likelihood of bankruptcy, dividend policy, or growth. Finally, we discuss policy implications of these findings.

Empirical studies of large publicly traded firms have shown a robust negative relationship between board size and firm performance. The evidence on small and medium-sized firms is less clear; we show that existing work has been incomplete in analyzing the causal relationship due to weak identification strategies. Using a rich data set of almost 7000 closely held corporations we provide a causal analysis of board size effects on firm performance: We use a novel instrument given by the number of children of the chief executive officer (CEO) of the firms. First, we find a strong positive correlation between family size and board size and show this correlation to be driven by firms where the CEO’s relatives serve on the board. Second, we find empirical evidence of a small adverse board size effect driven by the minority of small and medium-sized firms that are characterized by having comparatively large boards of six or more members.
