TY - JOUR AB - Purpose The purpose of this study is to examine how gratitude appeals and consumers’ sense of power jointly influence customer engagement in a service firm’s corporate social responsibility (CSR) initiatives. Based on previous literature, the authors propose that power moderates the effect of gratitude expression on consumers’ attitudes and behavioral intention to engage in matching donations.Design/methodology/approach A 2 (power: powerful vs powerless) × 2 (gratitude expression: included in the request vs none) between-subjects experiment was conducted to test the proposed hypotheses. Participants were asked to imagine that they recently saw a donation request while dining at a local restaurant and they then complete scales that measured their attitude and donation intention to engage in a restaurant’s CSR practice.Findings The findings of this study indicate that an expression of gratitude enhanced powerless but not powerful customers’ intention to engage in CSR practices. In addition, moderated mediation tests revealed social worth concerns as the underlying mechanism between gratitude expression and customer engagement for powerless consumers. However, such mediation effects were not observed for powerful consumers.Originality/value The current study identifies sense of power as a new psychological state that can influence donation behaviors in the context of CSR. In addition, the current study shows that the serial mediating role of social worth between gratitude expression and prosocial behaviors only holds true for individuals with a low sense of power.
