<p>Firms increasingly rely on entertainment value to communicate Corporate Social Responsibility (CSR), yet audiences often question sincerity and credibility. This study examines whether two orthogonal entertainment-value manipulations in CSR messages, hedonic entertainment and eudaimonic entertainment, positively predict moral elevation, and whether moral elevation is associated with CSR beliefs and downstream reputation-relevant outcomes under different levels of perceived argument specificity. Drawing on entertainment theory, moral elevation, and dual-process perspectives, we analyze data from a 2 (hedonic entertainment cues: absent vs. present) × 2 (eudaimonic entertainment cues: absent vs. present) between-subjects experiment (<i>N</i> = 384). Results showed that both hedonic and eudaimonic entertainment cues positively predicted moral elevation. Higher moral elevation was associated with stronger CSR beliefs, which, in turn, were associated with more favorable attitude toward the firm and greater support allocation to the CSR initiative. These associations were weaker when perceived argument specificity was higher. The study contributes by extending entertainment theory to CSR communication, identifying moral elevation as a key explanatory mechanism linking entertainment-based CSR messages to reputation-relevant outcomes, and positioning perceived argument specificity as an important boundary condition.</p>
