 The academic field of business ethics is shared by social scientists and normative theorists. But they address different questions. Social scientists try to answer descriptive questions like: Does corporate social performance improve corporate financial performance, i.e., does ethics pay (Vogel 2005; Zhao &amp; Murrell 2021)? Why do people engage in unethical behavior (Bazerman &amp; Tenbrunsel 2011; Werhane et al. 2013). How can we make them stop (Warren, Gaspar, &amp; Laufer 2014)? I will not consider such questions here. This entry focuses on questions in normative business ethics, most of which are variants on the question: What is ethical and unethical in business?
