Experiments in business ethics enable researchers to draw causal inferences about moral judgment and moral behavior. They can uncover the determinants of individual morality and help identify the psychological impact of factors that normative ethicists would typically not capture through introspection alone. Understanding these tendencies is important for informing the design of ethically aligned institutions that are intended to promote morally desirable behavior in complex social environments. To this end, experiments in institutional ethics systematically investigate the phenomena that arise from the interaction of multiple individuals and the influence of incentives on these phenomena. This is crucial for ensuring that well-intentioned institutions do not generate unintended adverse effects. Experiments in folk economics and folk ethics can contribute to a better understanding of how laypeople think about economic mechanisms and how they normatively assess economic processes and outcomes. Such findings are relevant for understanding how economists can communicate their field’s descriptive and normative implications in a more audience-appropriate way. Crucially, the aim of experimental business ethics is not to replace normative reflection but to complement it. Indeed, one of its central goals is to stimulate important new normative debates.
