This paper studies kinship band networks as capital market institutions. It explores two of the channels through which membership in a community where individuals are genealogically linked, such as a kinship group, can a¤ect their access to informal credit. The ...rst is that incentives to default are lower for community members who can expect retaliation to fall on their o¤spring as well as on...
In directed networks, reciprocal links have dramatic effects on dynamical processes, network growth, and higher-order structures such as motifs and communities. While the reciprocity of binary networks has been extensively studied, that of weighted networks is still poorly understood, implying an ever-increasing gap between the availability of weighted network data and our understanding of thei...
Decisions to engage in collaborative interactions require enduring considerable risk, yet provide the foundation for building and maintaining relationships. Here, we investigate the mechanisms underlying this process and test a computational model of social value to predict collaborative decision making. Twenty-six participants played an iterated trust game and chose to invest more frequently w...
Understanding how cooperative behaviour emerges within a population of individuals has been the focus of a great deal of research in the multi-agent systems community. In this paper, we examine the effectiveness of two different learning mechanisms – an evolutionary-based technique and a social imitation technique – in promoting and maintaining cooperation in the spatial N-player Iterated Priso...
This paper presents, in a series of simple diagrams, concise results about the replicator dynamics of direct and indirect reciprocity. We consider repeated interactions between donors and recipients, and analyse the relationship between three basic strategies for the donor: unconditional cooperation, all-out defection, and conditional cooperation. In other words, we investigate the competition ...
Work-for-welfare style unemployment policies have been introduced in the majority of western countries as part of an overarching contractual regime, which demands various prescribed forms of reciprocation of citizens who require government income support. Communitarian scholar, Lawrence Mead, argues that such policies are ethically justified because they demand 'civic equality' of unemployed ci...
Using data on 60 intentional communities from the Urban Communes Data Set, we examine factors related to the persistence of ties 12 years later, when nearly all members had left the groups. We find strong evidence of triadic effects—people are more likely to remain in contact with others when they share patterns of contact with third parties. Such triadic effects retain importance even when we ...
Human infants as young as 14 to 18 months of age help others attain their goals, for example, by helping them to fetch out-of-reach objects or opening cabinets for them. They do this irrespective of any reward from adults (indeed external rewards undermine the tendency), and very likely with no concern for such things as reciprocation and reputation, which serve to maintain altruism in older ch...
Viewing desperate love as marked by urgency, neediness, dependence, a great need for reciprocation, indealization, and affective extremes, personality traits leading to desperate love were examined. A sample of 251 undergraduates, in desperate love, nondesperate love, and random groups, completed several questionnaires examining characteristic qualities of self and important others and attitude...
How do people react to those who have helped them? The authors propose that a recipient's evaluation of a helper's intentions and the recipient's own attitudes about future interactions with the helper depend partly on the recipient's perceptions of how the helper decided to assist: on the basis of affect, of role, or of cost-benefit calculation. When a recipient perceives that the decision was...
