This study investigates the role that moral identity, religiosity, and the institutionalization of ethics play in determining the extent of justification of norm violating behavior among business practitioners. Moral justification is where a person, rather than assuming responsibility for an outcome, attempts to legitimize ethically questionable behavior. Results of the study indicate that both the internalization and symbolization dimensions of moral identity as well as intrinsic religiosity and the explicit institutionalization of ethics within the organization are significant determinants of the (...) moral justification of unethical behaviors.
