The theory of inclusive fitness has transformed our understanding of cooperation and altruism. However, the proximate psychological underpinnings of altruism are less well understood, and it has been argued that emotional closeness mediates the relationship between genetic relatedness and altruism. In this study, we use a real-life costly behaviour (travel time) to dissociate the effects of gen...

Inclusive fitness theory provides a compelling explanation for the evolution of altruism among kin. However, a completely satisfactory account of non-kin altruism is still lacking. The present study compared the level of altruism found among siblings with that found among friends and mates and sought to reconcile the findings with an evolutionary explanation for human altruism. Participants (16...

Unconditional altruism is an enduring puzzle for evolutionary approaches to social behavior. In this paper, we argue that costly signaling theory, a well-established framework in biology and economics, may be useful to shed light on the individual diVerences in human unconditional altruism. Based on costly signaling theory, we propose and show that unconditional altruistic behavior is related t...

The role of intergenerational altruism in explaining disparities between predicted and actual patterns of wealth accumulation is still unclear. Recent works suggests traditional testing methods may fail because altruism is in fact heterogeneous across the population. This paper uses a heretofore unexamined data set to attempt to identify demographic characteristics that may be correlated with i...

What are the determinants of altruism? While economists assume that altruism is mainly driven by fairness norms, social psychologists consider empathy to be a key motivator for altruistic behavior. To unite these two theories, we conducted an experiment in which we compared behavior in a standard economic game that assesses altruism (the so-called Dictator Game) with a Dictator Game in which pa...

Evolutionary theory postulates that altruistic behavior evolved for the return-benefits it bears the performer. For return-benefits to play a motivational role, however, they need to be experienced by the organism. Motivational analyses should restrict themselves, therefore, to the altruistic impulse and its knowable consequences. Empathy is an ideal candidate mechanism to underlie so-called di...

Hamilton's rule explains when natural selection will favor altruism between conspecifics, given their degree of relatedness. In practice, indicators of relatedness (such as scent) coevolve with strategies based on these indicators, a fact not included in previous theories of kin recognition. Using a combination of simulation modeling and mathematical extension of Hamilton's rule, we demonstrate...

Prior studies on family business, have found both positive as well as negative affects of altruism and entrenchment on firm performance. Drawing on theoretical underpinnings of resource based view, stewardship theory, and agency theory; we explain how ‘family involvement’ acts as a moderator in contingently explaining positive and negative effects of altruism and entrenchment on family firm per...
