Policies and explicit incentives designed for self-regarding individuals sometimes are less effective or even counterproductive when they diminish altruism, ethical norms and other social preferences. Evidence from 51 experimental studies indicates that this crowding out effect is pervasive, and...

Empirical evidence is provided for the importance of non-reciprocal pro-social behavior of individuals in an anonymous, n-person pure public good setting. A unique panel data set of 136,000 observations is matched with an extensive survey. Even under anonymous conditions, a large number of...

We develop a theory of prosocial behavior that combines heterogeneity in individual altruism and greed with concerns for social reputation or self-respect. Rewards or punishments (whether material or image-related) create doubt about the true motive for which good deeds are performed and this...

We examine behavioural models involved in the provision of public goods when income inequality exists within groups. Our sample consists of individuals from urban and rural South African fishing communities. We find that behaviour observed in unequal groups does not accord with models of...

Reciprocity is one of the main basic social relations that constitute societies. It consists of being favourable to others because others are favourable to you (and not from an exchange in the strict sense).

Altruism, giving and pro-social conduct, and reciprocity, are the basis of the existence and performance of societies, through their various occurrences: in families; among the diverse motives of the political and public sector; as the general respect and moral conduct which permit life in...

Important economic thinkers such as Sen, Arrow and Harsanyi have argued for the existence of multiple preference orderings, allowing individuals to make choices, both when only private welfare is at stake and when the good of some collective is involved. Further, recent literature has shown that...
