This research focuses on the information asymmetries between producers and consumers with regard to corporate social and environmental behavior. Similar to the nutrition facts Panel, the authors propose a facts panel on Corporate Social and Corporate Environmental Behavior (CSEB facts Panel) and test its effects on consumer response. Based on the results of a qualitative pre-study, findings of an experimental study demonstrate that when the CSEB facts Panel indicates responsible (vs. irresponsible) corporate behavior, companies can benefit from consumers’ increased willingness to pay a price premium. The authors discuss managerial, public policy, and theoretical implications.
