The purpose of this essay is to argue that process-regarding preferences or social norms are pervasive in traditional village communities, yet are subject to gradual erosion under the influence of new forces, particularly population growth and market penetration. This is illustrated with respect...

This paper addresses the question of whether our evolutionary history suggests that humans are likely to be individually selected selfish maximizers or group selected altruists. It surveys models from the literature of evolutionary biology in which groups are formed and dissolved and where the...

Since homo sapiens is a social animal, one might expect human nature the set of psychological propensities with which our species is naturally endowed to equip human beings to live in social groups. In this chapter, we consider the implications of this idea for economics and game theory. We...

Behind my reciprocation of a friend's gift may lie both instrumental reasons (I expect further future gifts) and communicative reasons (I want to establish or confirm a friendship per se ). In a theory of rational individual action, such communicative reasons can be incorporated as an argument...

Most economic models are based on the self-interest hypothesis that assumes that material self-interest exclusively motivates all people. Experimental economists have gathered overwhelming evidence in recent years, however, that systematically refutes the self-interest hypothesis, suggesting...

The goal of this paper is to draw some lessons for economic theory from research in psychology, social psychology and, more briefly, in biology, which purports to explain the formation of social preferences. We elicit the basic mechanisms whereby a variety of social preferences are determined in...

It consists of being favourable to others because others are favourable to you (and not from an exchange in the strict sense).
