Experimental evidence from modified dictator games and simple choice situations indicates that concern for overall welfare is an important motive in human decision making. Models of inequality averse agents, as suggested by Fehr and Schmidt (1999) or Bolton and Ockenfels (2000), fall short in explaining behavior of proposers, who reduce their payoff below a fair split of the endowment to maximize social welfare, while other types of social preferences do well on these data. This has created the impression that inequality aversion is a misguided concept. This paper presents a formal model and shows that a combination of welfare concern and inequality aversion changes this result in favor of inequality aversion. It also establishes a unique link between altruism and social welfare in the proposed model.
