Modeling Celebrity Endorsement and Consumer Buying Behavior Using STARS
Abstract

Celebrity endorsement has been one of the most successful mantras for grabbing the attention of the customers towards the products. This study focuses on the relationship between a celebrity and their role in endorsing a brand, and the combined effect of celebrity attractiveness, trustworthiness and celebrity-product matchup on consumer buying behavior and brand choice. Regression analysis was used to derive the mathematical equation about the choice of brand and attributes of celebrities. The findings reveal that ads featuring clebrities attract consumers, generating trust in the product. It is also found that the celebrity-product fit affects consumers’ purchase intention. Further, the study proposes an original 'STARS' model for celebrity endorsement, which is useful for brands to decide which celebrity to approach to for endorsement of their brand.
