International codes of corporate behavior have been proposed, discussed, negotiated, and promulgated by governments, transnational corporations, and inter-corporate associations over the past few decades. It is not clear that they have been resoundingly as successful in changing corporate behavior – particularly as to corruption and environmental protection – as have national government requirements imposed on foreign enterprises and their own officials. This article arrays the many attempts to structure cooperative action to re-order corporate behavior on several dimensions – restrictive business practices, labor conditions, human rights, environmental production, and corruption. It then assesses the extent to which behavior has been changed and what techniques are more effective in making corporate behavior more ethical.
