Freedom of choice between unitary and two-tier boards: an empirical analysis
Résumé
We examine board structure in France, which since 1966 has allowed firms freedom to choose between unitary and two-tier boards. We analyze how this choice relates to characteristics of the firm and its environment. Firms with severe asymmetric information tend to opt for unitary boards; firms with a potential for private benefits extraction tend to adopt two-tier boards. There is enhanced sensitivity of CEO turnover to performance at firms with two-tier boards, indicating greater monitoring. Our results are broadly consistent with the Adams and Ferreira (2007) model and suggest there are gains from allowing freedom of contract about board structure.
