Influential or frequently cited business ethics research does not appear in a vacuum; our study reveals its predominant sources and contributors by discipline. By examining citations from articles published in three top business ethics journals (Journal of Business Ethics, Business Ethics Quarterly and Business Ethics: A European Review) over the period 2004–2008, we document that the preponderance of influential business ethics research comes primarily from the management faculty. In addition, management journals and management books are the predominant sources for influential business ethics research. Further, among the management fields, organizational behavior and organizational structure predominate leadership and strategy as the major subject areas for influential business ethics research, suggesting that this influential body of research is focused on a micro rather than on a macro context. These empirical results lend credence to the perception that there is a silo effect in influential business ethics research and suggest that business ethics research in a micro context might have permeated to the teaching of business ethics.
