| Abstract;Altruistic behavior in a human population can be explained by a model of indirect reciprocity. A key idea here is to express our evaluations of other people's altruistic behavior and store them in some kind of forms for later use. This paper proposes a model of indirect reciprocity based on money in an abstract sense as externalization of internal images of others. Simulation results have shown that money can build a cooperative relationship in a larger group compared to the relationship based on internal image, but it is largely influenced by macro factors. The results of the simulation with money and internal images have shown that money can coexist with internal images, which leads to a more stable cooperative relationship, but that once the relationship is disrupted, it is occasionally hard to resume. This paper also discusses a scenario for the origin and emergence of human cooperative society based on the simulation results. (author abst.) |
