The tradition of keeping written records of gift received during household ceremonies in many countries offers researchers an underutilized means of data collection for social network analysis. This paper first summarizes unique features of the gift record data that circumvent five prevailing sampling and measurement issues in the literature, and we discuss their advantages over existing studie...

The folk theorem allows a very unequal division between players. In nonrepeated experimental games with many equilibria, such as ultimatum, observed play involves a relatively equal division between players. In a two-player repeated game setting there is a simple intuition about this: a poor player has little to lose by deviating from his equilibrium strategy. So a rich player ought to be willi...

This paper suggests a relationship model for describing, analyzing and foreseeing conflicts of interest in file-sharing networks. The model includes levels of relationship ranging from the individual (ego), to the small group of close peers (micro), to a larger network of acquaintances (meso) to the anonymous larger network (macro).

We tested the hypothesis that gifts act as markers of interpersonal similarity for both acquaintances and close relationship partners. Participants were led to believe that a new opposite sex acquaintance (Experiment 1) or romantic partner (Experiment 2) had selected either a desirable or undesirable gift for them. In Experiment 1, men viewed themselves as less similar to their new acquaintance...

Nuptial food gifts given by males to females at mating are widespread in insects, but their evolutionary origin remains obscure. Such gifts may arise as a form of sensory trap that exploits the normal gustatory responses of females, favouring the selective retention of sperm of gift-giving males. I tested this hypothesis by offering foreign food gifts, synthesized by males of one cricket specie...
