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 …

A symmetric network consists of a set of positions and a set of bilateral links between these positions. Examples of … symmetric network we define a cooperative transferable utility game that measures the power of each coalition of positions in … the network. Applying the Shapley value to this game yields a network power measure, the beta-measure, which reflects the …

These two arguments do not distinguish between … abilities andtrust in intentions). The closure argument emphasizes that dense network structures enforceindividuals to be …
