Since seminal meta-analytical work in 2006 we have witnessed burgeoning research on ethical climates. This article offers a comprehensive review of literature examining the antecedents and outcomes of ethical climates over the last decade, as well as moderators of the relationship between ethical climates and other variables. Based on the review, an agenda for future research is also presented. In addition to highlighting the potential for incorporating alternative theoretical perspectives such as situational strength theory, trait-activation theory, social information processing theory, and institutional theory to better our understanding of ethical climates, this article highlights the need for future research to incorporate a dynamic perspective to study ethical climates, examine the curvilinear effects of ethical climates on work outcomes, extend the study of ethical climates to different levels of the organization, and examine the effects of culture on ethical climates.
