“…Our study contributes to the literature on what people view as a fair distribution and how fairness considerations shape individual behavior (e.g., Fehr and Schmidt, 1999;Konow, 2000;Cherry, Frykblom, and Shogren, 2002;Falk, Fehr, and Fischbacher, 2003;Tyran and Sausgruber, 2006;Cappelen, Drange Hole, Sørensen, and Tungodden, 2007;Konow, Saijo, and Akai, 2009;Almås, Cappelen, Sørensen, and Tungodden, 2010;Cabrales, Miniaci, Piovesan, and Ponti, 2010;Rodriguez-Lara and Moreno-Garrido, 2012;Cappelen, Moene, Sørensen, and Tungodden, 2013b;Durante, Putterman, and Weele, 2014;Bartling, Weber, and Yao, 2015;Jakiela, 2015). A number of papers both in social psychology and in behavioral economics have shown that a majority of people appear to view income inequalities as fair if the inequalities are proportional to differences in performance (e.g., Adams, 1965;Walster, Berscheid, and Walster, 1973;Leventhal, 1980;Konow, 2000;Frohlich, Oppenheimer, and Kurki, 2004;Cappelen, Sørensen, and Tungodden, 2010;Cappelen et al, 2007Cappelen et al, , 2013a.…”
