A review of arguments for and against including business ethics courses in the Master of Business Administration (MBA) curriculum reveals strongly opposing views. Those favoring business ethics courses argue that such courses teach a way to approach and think through a problem and provide a framework for judging behavior, that the university must respond to the needs of business, and that such courses are offered by a majority of schools. Those opposing ethics courses contend that such courses are unnecessary because businesses should not be required to be socially responsible, there is little agreement about course content, corporate responsibility is too vague and idealistic a concept to be taught, graduate students already have firm ideas of right and wrong, students do not consider them necessary, the courses compete with essential classes, faculties lack expertise, some firms will not provide tuition reimbursement, and teachers would be teaching at a trade school level. In the analysis following this summary, it is concluded that few of the arguments against teaching ethics are valid, but none of the arguments for the subject are strong enough to warrant requiring such courses. Teaching about ethics should be concerned with ways of thinking through value judgments, not with value judgments themselves. (IS)
