“…Social norms have long been of interest to social scientists and economists (Cahan, Chen, & Chen, 2017; Coleman, 1986, 1990; Elster, 1989; Hong & Kacperczyk, 2009; Horne, 2009; Krupka & Weber, 2013; Lindenberg, 2008; Opp,1982; Rost & Weibel, 2013) and are suggested to act as default rules in social dilemmas (Biel & Thøgersen, 2007). An increasing number of researchers apply this concept to explain social responsibility (Blay et al, 2019; Cahan et al, 2017; Shen & Benson, 2016), honesty (Blay et al, 2019), gambling (Callen & Fang, 2020), diversity (Chang, Milkman, Chugh, & Akinola, 2019), cooperation (Fehr & Fischbacher, 2004a; Pillutla & Chen, 1999), and fairness (Fehr & Fischbacher, 2004b; Rabin, 1993; Rost & Weibel, 2013). Among social norms, fairness norms are suggested to be especially important (Binmore, 1998; Brosnan & de Waal, 2014; Opp, 1982).…”
