The purpose of this paper is to analyze the relationship between national culture and ethical decision making. Established theories of ethics and moral development are reviewed and a culture-based model of ethical decision making in organizations is derived. Although the body of knowledge in both cross-cultural management and ethics is well documented, researchers have failed to integrate the influence of cultural values into the ethical decision-making paradigm. A conceptual understanding of how managers from different nations make decisions about highly ethical (...) issues will provide business ethics researchers with a sound theoretical foundation upon which future empirical inquiry can be based.
