Cause-Relating Marketing: The Effects of Purchase Quantity and Firm Donation Amount on Consumer Inferences and Participation Intentions

A conceptual model for a cause-related marketing (CRM) campaign, which examines the effects of purchase quantity and firm donation amount on consumer perceptions of the firm (i.e., firm motive and corporate social responsibility) and participation intentions, is developed and tested in three separate studies. In Study 1, we find the positive effect of firm donation amount on participation intentions was fully mediated by consumer inferences about the firm and the negative effect of purchase quantity on participation intentions was only partially mediated by these inferences. In Study 2, and consistent with the persuasion knowledge model, we demonstrate that the effects of purchase quantity on firm inferences and subsequent participation intentions are moderated by consumer participation effort where higher participation requirements (e.g., mail-in proof-of-purchase) yield more negative purchase quantity effects. We extend the model in Study 3 to incorporate multiple exchange mechanisms and find that although purchase quantity does affect participation intentions by social exchange, the effects of purchase quantity are primarily the result of the economic exchange. Recommendations for the design of cause-related marketing campaigns and for future research are discussed.
