Board of Directors and Ethics Codes in Different Corporate Governance Systems

摘要

Business ethics is one of the most significant demands made by institutional and individual investors, who usually require the participation of the board of directors in the planning and implementation of ethical behaviour in corporations. This is done by drawing up an ethics code (EC) and then monitoring its fulfilment. This study has a dual objective: first, to analyse the role played by the composition of the board of directors, and by that we mean its independence and the diversity of its members, on the implementation and scope of an EC, and, second, to detect whether the corporate governance (CG) system moderates the level of involvement of the board in ethical issues. The findings obtained from a data panel sample made up of 760 listed companies from 12 countries for the years 2003-2009 show that the largest companies with large-sized and diverse boards implement the most developed ECs. Nevertheless, the extent of involvement of the independent directors is conditioned by the level of shareholder orientation characteristic of the system of CG in the corporation's country of origin.
