This paper examines through the lens of sport whether male and female customers as well as differently aged customers focus on different celebrity characteristics and whether they are influenced by celebrities' facial attractiveness. Drawing on psychological and sociological theories like attachment theory, social role theory of gender, or social norm theory as well as on the academic literature on celebrity endorsement in general, we develop several hypotheses regarding how a fan's age and gender affect the importance of key characteristics of football starsnamely experience, personality, exemplary behavior, and skills. Using a proprietary dataset that combines archival data concerning professional football players and clubs with survey data of more than 2100 football fans, we find evidence that female fans attach more importance to a player's personality and behavior while male fans seem to focus on experience and skills. We further find that when fans get older, the importance of a player's behavior and experience increases. Moreover, our results show that the facial attractiveness of players clearly influences fan perceptions. Our results contribute to existing research on customer segmentation by providing a & Daniel Hoegele more differentiated picture of the effects of key celebrity characteristics on different customers.

This paper examines the effect of superstars on external stakeholders’ organizational identification through the lens of sport. Drawing on social identity theory and the concept of organizational identification, as well as on role model theories and superstar economics, several hypotheses are developed regarding the influence of soccer stars on their fans’ degree of team identification. Using a proprietary data set that combines archival data on professional German soccer players and clubs with survey data on more than 1,400 soccer fans, this study finds evidence for a positive effect of superstar characteristics and role model perception. Moreover, it is found that players who qualify for the definition of a superstar are more important to fans of established teams than to fans of unsuccessful teams. The player's club tenure, however, seems to have no influence on fans’ team identification. It is further argued that the effect of soccer stars on their fans is comparable to that of executives on external stakeholders, and hence, the results are applied to the business domain. The results of this study contribute to existing research by extending the list of personnel‐related determinants of organizational identification.

Purpose – The purpose of this paper is to examine the effect of superstars (and other factors) on football fans’ attraction to competition (i.e. disloyal behavior). Design/methodology/approach – A proprietary data set including archival data on professional German football players and clubs as well as survey data of more than 900 football fans is used. The hypotheses are tested with two-sample mean-comparison t-tests and multivariate probit models. Findings – This study provides evidence that superstars both attract new fans and contribute to the retention of existing fans. While the presence of superstars, team loyalty and team identification prevent football fans from being attracted to competition, the team's recent performance seems to have no effect. Fans who select their favorite player from a competing team rather choose superstars, young players, players who are known for exemplary behavior and defenders. Originality/value – This paper contributes to existing research by expanding the list of antecedents of disloyalty and by being the first to employ independent, quantitative data for the assessment of superstar characteristics in the context of team loyalty.

This paper examines the effect of superstars on external stakeholders' organizational identification through the lens of sport. Drawing on social identity theory and the concept of organizational identification, as well as on role model theories and superstar economics, we develop several hypotheses regarding the influence of soccer stars on their fans' degree of team identification. Using a proprietary dataset including archival data on professional German soccer players and clubs as well as survey data of more than 1,400 soccer fans, we find evidence for a positive effect of superstar characteristics and role model perception. We further find that players who measure up to the definition of a superstar are more important to fans of established teams than to fans of unsuccessful teams. The player's club tenure, however, seems to have no influence on fans' team identification. We argue that the effect of soccer stars on their fans is comparable to that of CEOs on their organizations' external stakeholders and consequently apply our results to the business domain. Our results contribute to organizational identification research by extending the list of determinants related to individual persons.
