“…The effects of social networks (e.g., peer effects) on individual behaviors and outcomes are already amply documented in the contexts of work time (Collewet, 2015), education (Hanushek, Kain, Markman, & Rivkin, 2003), smoking (Ali & Dwyer, 2009), obesity (Gwozdz et al, 2019), fast food consumption (Fortin & Yazbeck, 2015), crime (Bayer, Hjalmarsson, & Pozen, 2009), financial decisions (Bursztyn, Ederer, Ferman, & Yuchtman, 2014), and agricultural revenue (Songsermsawas, Baylis, Chhatre, & Michelson, 2016).
