E-participation: social capital and the Internet

We add to the literature by conducting the first empirical assessment of how online networking affects two economically relevant aspects of social capital, i.e. trust and sociability, in a large and representative sample. We address endogeneity in online networking by exploiting technological characteristics of the pre-existing voice telecommunication infrastructures that exogenously determined the availability of broadband for high-speed Internet. We find that participation in SNSs such as Facebook and Twitter has a positive effect on face-to-face interactions. However, social trust decreases with online interactions. We argue that the rising practice of hate speech may play a crucial role in the destruction of trust.
