Introduction -- Board composition and its heterogeneity -- Directors' characteristics and firm's performance: research design and hypotheses -- Family firms board characteristics -- Econometric analysis -- Conclusions.

This book expands on the literature on the characteristics of management boards by especially focusing on family-listed and family-controlled companies, as they are ideal for studying board heterogeneity. It uses specific multidimensional indices and in-depth econometric analysis to introduce new variables, such as international experience, that represent a source of competitive advantage for firms in today's globalized world. In addition, by examining the heterogeneity ratio and the representation of independent and family directors, the book demonstrates how family-controlled firms use independent directors to import their heterogeneous expertise. The book makes a threefold contribution: for regulators, it offers suggestions on improving the quality of reporting in family-controlled firms; for researchers, it demonstrates the importance of including directors' characteristics apart from the firm-specific factors in their analyses; and for practitioners, it shows that selecting directors with specific characteristics can have a substantial impact on firms' performance. .
