 Another explanation for the retreat of philosophers from business ethics appeals to supply. There are hardly any philosophy Ph.D. programs that have faculty specializing in business ethics and, as a result, few new Ph.D.’s are produced in this area. Those who work in the area are typically “converts” from mainstream ethical theory and political philosophy. Some good news on this front is the recent increase in the number of normative theorists working on issues at the intersection of philosophy, politics, and economics (PPE). Many of the topics these scholars address—the value and limits of markets, the nature of the employment relationship, and the role of government in regulating commerce—are issues business ethicists care about. But PPE-style philosophers hardly cover the whole field of business ethics. There remain many urgent issues to address.
