Envy as a Secondary Criterion of Fairness

In the recent experimental literature several utility models
have been suggested that address observed behavior not
reducible to the pursuit of self-interest. Most models are
based on some kind of social preferences, where the payoff
distribution is relevant for an individual's utility. Envy
has repeatedly been mentioned as an explanatory factor. Envy
is a central criterion in the theoretical literature on fair
division, whose definition differs from the more casual
usage of the word envy in the experimental literature. We
analyze several fair division problems where envy and social
preferences can be distinguished. Envy is shown to matter,
although only as a secondary criterion.
