Bargaining power and the evolution of un-fair, non-mutualistic moral norms
1Department of Economics, Università degli Studi di Milano, 20122 Milan, Italy. francesco.guala@unimi.it
Abstract:
Mutualistic theory explains convincingly the prevalence of fairness norms in small societies of foragers and in large contemporary democratic societies. However, it cannot explain the U-shaped curve of egalitarianism in human history. A theory based on bargaining power is able to provide a more general account and to explain mutualism as a special case. According to this approach, social norms may be more variable and malleable than Baumard et al. suggest.
