Implicit in most comparative ethical studies is the assumption that cultural and religious differences between countries are the major reasons behind the variations in ethical beliefs and business practice across nations. This article examines research on the international ethical issues and the common moral concerns that permeate differing religious and philosophical perspectives--not only Judaism and Christianity, but also Islam, Hinduism, Buddhism, and Confucianism with emphasis on the Golden Rule. Many commonalities were found. The authors suggest that students (and practitioners) should understand the basic tenets of the major religions and their implications on international business ethics because of the apparent failure of current philosophical approaches.
