EFFECTS OF ENVIRONMENT KNOWLEDGE ON AGGLOMERATION AND COOPERATION IN SPATIAL PUBLIC GOODS GAMES

摘要

Nowadays, our society is characterized by high levels of social cohesion and cooperationnthat are in contrast with the selfish nature of human beings. One of the principalnchallenges for the social sciences is to explain the emergence of agglomeration and cooperativenbehavior in an environment characterized by egoistic individuals. In this papernwe address this long standing problem with the tools given by evolutionary game theory.nSpecifically, we explore a model in which selfish individuals interact in a publicngoods creation environment. As a further ingredient each agent is characterized by annindividual expectation and, if unsatisfied, can change its location. In this scenario wen1250056-1nC.-Y. Xia, S. Meloni and Y.

Moreover, our results demonstratenthat only in extreme and very competitive environments cooperation and agglomerationnare lost.
