“…Interestingly, in a similar experiment where subjects engage in a real-effort task to generate donations to a charity, Jones and Linardi (2012) find that making contributions observable to future participants increases the effort of male participants but decreases the effort of female participants. Other related studies include Rege and Telle (2004), Dana, Weber, and Kuang (2007), Andreoni and Bernheim (2009), Ariely, Bracha, and Meier (2009), Xiao and Houser (2011), Pan and Houser (2011), Carpenter and Myers (2010), Linardi and McConnell (2011), and Tadelis (2011). 4 Further evidence can be found in field studies on household energy consumption (Schultz et al, 2007), charitable giving (Della Vigna et al, 2011) and voter turnout (Gerber et al 2008).…”
