Links and Architecture in Village Networks
利用埃塞俄比亚农村数据检验网络形成模型，发现链接数量和网络架构共同决定社会网络对结果的影响，社会资本的作用因所属网络架构而异。
In this article we test the implications of a model of network formation on data from rural Ethiopia. In contrast to the current literature, we demonstrate the critical role of both number of links and architecture in determining the impact of social networks on outcomes. Social capital matters, but its impact differs by the architecture of the network to which one belongs. Copyright © The Author(s). Journal compilation © Royal Economic Society 2009.
