This paper offers a cross-disciplinary examination of ethics education in MBA programs. Based on survey data underlying the Beyond Grey Pinstripes (BGP) ranking we find: (1) that most courses covering ethics content, and especially standalone ones, are electives, (2) that integration of ethical issues into the curriculum focuses on a few selected disciplines, and (3) that over time schools increase the absolute number of courses, however without changing their core/elective status and their affiliation with selected disciplines. We argue that these results point towards a problem: business schools increasingly risk creating a gap between their upbeat rhetoric around ethics education and their actual curriculum. We explain why our findings imply such decoupling and suggest that, given the persistence of ethical problems in today’s business environment, more mandatory ethics courses as well as a stronger integration of ethics-related debates in disciplines like finance and accounting are needed. We claim that decoupling is likely to emerge because business schools face a conflict between increasing external institutional pressures to legitimize their MBA programs and internal impediments to fully integrate ethics education into the curriculum.
