Society continues to be concerned about the impact of ethics on decision making. While many researchers have focused on this issue, the increased globalization of today's business suggests that more emphasis should be given to the potential impact of culture on ethical decisions. The current study is based, in part, on the work of Hofstede (1980, 1991) who identified multiple dimensions on which countries differ in terms of culture. As such, it gives consideration to the impact of national culture on ethical decision making. The study focuses on ethical decisions made by U.S. and Taiwanese accounting students and examines cross-cultural differences in business-related ethical perceptions. Results indicated significant differences between the ethical perspectives and judgments of U.S. and Taiwanese accounting students in a whistle-blowing scenario, particularly with respect to Hofstede's individualism dimension. These findings enhance our understanding of cross-cultural ethical differences. The implications of these results are discussed and suggested areas for future research are proposed.
