Abstract
I argue that Plato was right in claiming that justice is more profitable, more rational, and more intrinsically valuable than injustice, and that this is particularly true for business organizations. The research on prisoners’ dilemmas and social dilemmas shows that ethical behavior is more profitable and more rational than unethical behavior in terms of both the negative sanctions on unethical behavior when interactions with stakeholders are iterated, and the positive rewards of habitually ethical behavior when stakeholders can identify those who are predisposed to be ethical. In addition, the psychological research on justice shows that justice is intrinsically valued, both from an outcome and from a process perspective, and so crucial for business organizations, particularly in terms of organizational effectiveness
