In this paper we develop a framework of pro-social behaviour for understanding and explaining soccer fans’ intentions to buy shares from their club in order to provide assistance in times of financial need. Based on the theory of norms, two alternative versions of the framework are empirically tested. Our results yield support for a mediating role of personal norms in the relationship between s...
