Celebrity Endorsement for Nonprofit Organizations: The Role of Celebrity Motive Attribution and Spontaneous Judgment of Celebrity-Cause Incongruence

This study investigated relationships among celebrity motive attribution, celebrity-cause congruence, and involvement with a cause. A 2 (altruistic motive: high vs. low) X 2 (congruence: high vs. low) X 2 (involvement: high vs. low) experimental study examined perceptions of celebrity credibility, attitudes toward celebrity endorsement and nonprofit organization, and intentions to donate money and volunteer time. The findings attest to main effects of causal attribution of a celebrity's altruistic motive and interaction effects between motive attribution and congruence (i.e., spontaneous judgment of celebrity-cause incongruence). Further, three-way interaction effects suggest the role of involvement in spontaneously activating celebrity-cause disassociation.     

Female,married and endorsing: integrating celebrity marital status,role congruence and credibility

In this study, we investigate the effect of marital status and perceived role congruence (RCN) of a female celebrity endorser on consumer attitudes incorporating the role of credibility in the Indian context. The research hypotheses were tested using a series of experimental designs. The main study had a 4 (Celebrity: Unmarried/Just Married/Married but Endorsing/Married and Comeback) × 2 (Product: Role Congruent/Role Incongruent) full factorial design. Non-student samples were used in this study. Major findings implied a significant effect of celebrity marital status, RCN and the interaction term on consumer attitudes. The three source credibility dimensions were found to have differential effects on consumer attitudes when they were included as moderators. This study finds evidence in support of diminishing effectiveness of female celebrities over time/marriage. In this study, we explored a new dimension of congruence (RCN) and found the same to influence consumer attitudes favourably towards the endorsed product.     

Celebrity versus film persona endorsements: Examining the effect of celebrity transgressions on consumer judgments

This study introduces film personas (e.g., Hermione Granger, Jack Sparrow, Bridget Jones) as effective brand endorsers. A three study, mixed‐method approach is used. Results show that a film persona (e.g., Legolas, from Lord of The Rings, vs. celebrity, Orlando Bloom) is a more (less) effective endorser (i.e., resulting in more positive attitudinal and behavioral judgments). Exploratory findings indicate that this may be due to film personas possessing a tight (vast) association set, which is more (less) easily transferred onto the endorsed brand. Results of this study also illustrate that endorsed brands are shielded from the negative effects of celebrity transgressions when they are featured as their film persona in an endorsement. This study has important implications for advertisers in the choice and execution of their advertisements featuring celebrities.
