Although the financial contribution to the common good has been investigated in social dilemma research, the psychological literature has mostly focused on understanding why and when people make cooperative rather than selfish choices by examining a number of constructs ranging from internal psychological variables, such as social value orientation (Van Lange, 1999), Machiavellian traits (Czibor, Vincze, & Bereczkei, 2014), social identity (Brewer & Kramer, 807247S GOXXX10.1177/2158244018807247SAGE OpenCastiglioni et al research-article20182018 1 Università Cattolica del Sacro Cuore, Milan, Italy 1986), empathy (Batson et al, 1995), and emotions (Ketelaar & Tung Au, 2003), to external variables, such as incentives and sanctions (Molenmaker, De Kwaadsteniet, & Van Dijk, 2016), information (Van Dijk, De Kwaadsteniet, & De Cremer, 2009), and framing effects (Van Dijk & Wilke, 1997). However, all these studies tend to use money as a way to operationalize people's contribution rather than made it the object of study itself.…”
