Can ethics be taught in accounting

Abstract This paper extends the work of accounting educators and researchers who have sought to develop and implement effective ethics interventions in the accounting curriculum. Its purpose is to assess the influence of ethics interventions, integrated into a one-semester introductory auditing course at both the undergraduate and graduate level, on the moral development and ethical behavior of accounting students. Ethics interventions were based on the review and discussion of ethics cases following a well known pedagogical framework over the first 10 weeks of one academic semester. The effectiveness of these interventions was tested two ways. First, using the Defining Issues Test (DIT) and a pre/post-test research design, the moral development of accounting seniors and graduate students in four separate auditing classes was assessed. Second, students' unethical behavior, defined as excessive “free-riding” on an economic-choice experiment based on the Prisoners' Dilemma, was observed by the researcher. In summary, results of this study show that ethics interventions did not cause accounting students' level of ethical reasoning to develop (increase) and did not curtail students' free-riding behavior. Findings also provide evidence of an association between ethical reasoning and students' economic choices, where students with relatively low and high levels of ethical reasoning were most likely to engage in free-riding. The implications of these findings are discussed in the last section of the paper.
