In this paper we test the celebrated `Strength of weak ties' theory of Granovetter (1973). We test two hypotheses on the network structure in a data set of collaborating economists. While we find support for the hypothesis of transitivity of strong ties, we reject the hypothesis that weak ties...

We use a unique regulatory event that occurred in Queensland, Australia, from 2007- 2012, to examine the predictive power of landowner relationship networks and lobbying behaviour on successfully gaining value-enhancing rezoning. A State authority, the Urban Land Development Authority (ULDA),...

In this paper, the search model is proposed, in which homogeneous firms are uncertain about the job seekers' number of friends, who can help them in the job search (social capital). All workers have the same productivity and differ only in the social capital. A firm offers a take-it-or-leave-it...

This paper develops a search model with heterogeneous workers and social networks. High ability workers are more productive and have a larger number of professional contacts. Firms have a choice between a high cost vacancy in the regular labour market and a low cost job opening in the referral...

Studies in the social capital literature have documented two stylised facts: first, a decline in measures of social participation has occurred in many OECD countries. Second, and more recently, the success of social networking sites (SNSs) has resulted in a steep rise in online social...

We explore how participation in social networking sites (SNS) such as Facebook and Twitter affects the most economically relevant aspect of social capital, trust. We use measures of trust in strangers (or social trust), trust in neighbours and trust in the police. We address endogeneity in the...
