To do so, social fundraising campaigns increasingly rely on social influence to motivate individuals to donate. This study aims to analyze the impact of social influence by using descriptive and injunctive social norms on the intention to donate, considering also the central roles that two personal characteristics–i.e., affinity with the social cause and past giving behavior–can play as moderators. The study findings enable us to provide both theoretical and practical implications.2021http://zaguan.unizar.es/record/14844910.1080/10696679.2020.1859335http://zaguan.unizar.es/record/148449oai:zaguan.unizar.es:148449info:eu-repo/grantAgreement/ES/DGA/SS54-17Rinfo:eu-repo/grantAgreement/ES/MICINN-FEDER/ECO2017-83993-PJournal of Marketing Theory and Practice 29, 3 (2021), 375-386by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
