“…The CEB literature proposes that customers can have different motives to engage in these behaviors (Jaakkola and Alexander, 2014;van Doorn et al, 2010). Moreover, customers can target different actors (e.g., the firm, its employees, other customers) with CEBs (e.g., Brodie et al, 2011;Verleye et al, 2014). From the aforementioned description, CEBs overlap with customer voluntary performance (CVP) and customer citizenship behaviors (CCBs), which are defined as, respectively, "helpful, discretionary behaviors of customers that support the ability of the firm to deliver service quality" (Bettencourt, 1997, p. 384) and "voluntary and discretionary behaviors that are not required for the successful production and/or delivery of the service but that, in the aggregate, help the service organization overall" (Groth, 2005, p. 11).…”
