•      Social capital theorists say that reputations circulate in dense and highly homogeneous social networks. However, Yamagishi (1998) distinguishes the trust to specified others from the trust to unspecified ones. He points out that such a reputation cannot promote cooperation toward unspecified others. I built a model based on Macy & Sato (2002), assuming that a network was modified by the reputations via one-step neighbors. I analyze the relation between cooperation to general others and opportunity costs. As a result, when opportunity costs are extremely small, a star-type network tends to be formed, and social order to cooperate to unspecified others is generated by agents who can access many reputations. It also became clear that when opportunity costs are extremely large, market-shaped order is generated from reputations.
