 With the growing popularity of social media, marketers increasingly employ strategies that target communities of consumers (Muniz & O’Guinn, 2001; Wuyts, Dekimpe, Gijsbrechts, & Pieters, 2010). One strategy is ‘influencer marketing’ — the practice of recruiting central consumers, i.e., consumers with relatively large number of social ties in the group, to spread word-of-mouth about brands (Noyan 2017; Likqia, 2016; Garcia, 2017). Centrality has multiple indices, but herein, we focus on the psychological states that emanate from degree centrality — the number of ties one holds in a social network.
