The most mentioned reason for continued membership is helping others. Therefore, the preliminary study concludes that there might be a role of generosity influencing intention. This study aims to develop a conceptual model linking generosity to intention. The method used for critical review is PRISMA systematic review. The result of the critical review is used as the based for concept development. More than three hundred publications published after 2007 in Science Direct were screened with key words “generosity” and “charity”. Finally, thirty journals were included in this review. The finding is that the most discussed topics are terminology (3 journals), motivation (16 journals), consequences (5 journals), and attributes of generosity (5 journals). Based on the review results, two possible relationships between generosity and intention are proposed. The first is that generosity, mediated by positive emotion, will influence intention. The second is that generosity has a direct influence on intention. It concludes with the need for further study to find empirical validation of the two possible relationships between generosity and intention. This is the first study proposed to link the generosity to intention.
