Media and Social Capital
综述了经济学中关于媒体技术对社会资本影响的实证文献，涵盖社会参与、政治参与和人际信任等结果，并分析了媒体内容、协调效果和网络特征的作用。
We survey the empirical literature in economics on the impact of media technologies on social capital. Guided by a simple model of information and collective action, we cover a range of different outcomes related to social capital—from social and political participation to interpersonal trust—in its benign and destructive manifestations. The impact of media technologies hinges on their content (information versus entertainment), their effectiveness in fostering coordination, and the networks they create as well as on individual characteristics and media consumption choices.
