A preference foundation for Fehr and Schmidt's model of inequity aversion

Abstract

Fehr and Schmidt (FS) introduced an influential social utility function for individuals in interpersonal contexts that captures self-centered inequity aversion. The value of this social utility function lies in its exceptionally good balance between parsimony and fit. This paper provides a preference foundation for exactly the model of FS with preference conditions that exactly capture the exceptionally good balance of FS. Remarkably, FS is a special case of Schmeidler's rank-dependent utility for decision under uncertainty. © The Author(s) 2009.
