Abstract

When faced with disaster, strangers, who are not embedded in dense networks, occasionally create communities in which they help one another. This paper introduces a new strategy, Sharing, into the classic Hawk-Dove game and analyzes under what conditions communities emerge and persist. The analyses showed that Sharings are more likely to dominate the population when the value of resources is higher than the cost of fights, although emerged communities do not always persist, due to the invasion of Dove strategies. Future studies should clarify how communities prohibit the expansion of Doves in the population, taking account of spatial structure or asymmetry in resource holding potential.
