We build a theory of prosocial behavior that combines heterogeneity in individual altruism and greed with concerns for social reputation or self-respect. The presence of rewards or punishments creates doubt as to the true motive for which good deeds are performed, and this 'overjustification...

This paper proposes a novel explanation for the context dependency of individual choices in two-player games. Context dependency refers to the well-established phenomenon that a player, when choosing from a given opportunity set created by the other player’s strategy, chooses differently in...

There is growing evidence on the roles of fairness and social preferences as fundamental human motives, in general, as well as in voting contexts. In contrast, models of political economy are based on selfish-voters who derive utility solely from 'own' payoff. We examine the implications of...

We implement the Rawlsian thought experiment of a veil of ignorance in the laboratory which introduces risk and possibly social preferences. We find that both men and women react to the risk introduced by the veil of ignorance. Only the women additionally exhibit social preferences that reflect...

We argue that with interdependent utility functions growth can lead to a decline in total welfare of a society if the gains from growth are sufficiently unequally distributed in the presence of negative externalities, i.e., envy.

Many diverse problems in economics can only be reasonably explained by assuming that people have social preferences, i.e., in addition to their own payoffs they are altruistic towards those who are poorer and envious towards those who are richer. How do people with social preferences choose...

Common tax competition models suggest that welfare states will undercut each other's tax rate to attract taxpayers and keep welfare recipients at bay. This will lead to a zero-taxation outcome in the absence of migration costs or other barriers to migration. This paper develops a two-country...

This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...

The median voter model (direct democracy) has wide applicability, but it is based on selfish voters i.e. voters who derive utility solely from 'own' payoff. The recent literature has pointed to fairness and concern for others as basic human motives that explain a range of economic phenomena. We...

The celebrated relation between inequality and redistribution is based on selfish voters who care solely about own-payoffs. A growing empirical literature highlights the importance of other regarding preferences (ORP) in voting over redistribution. We reexamine the relation between inequality...
