Bargaining power and the evolution of un-fair,non-mutualistic moral norms

摘要

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.
