This paper examines an important issue facing academia-pay inversion. It discusses how inversion is accompanied by ethical issues including secrecy, moral dilemmas for faculty, honesty, and keeping promises. It then examines this issue from five ethical viewpoints: a legalistic perspective, ethical egoism, utilitarianism, distributive justice, and Kant's deontological approach. As part of the discussion, the effect of the moral philosophy on the university's corporate culture is examined, with attention given to morale and productivity. Finally, alternatives to pay inversion that universities may want to consider are discussed.
