Leij, Marco van der; Goyal, Sanjeev - 2006

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...

Characterizations of network power measures

Brink, René van den; Borm, Peter; Hendrickx, Ruud L. P.; … - 2005

A symmetric network consists of a set of positions and a set of bilateral links between these positions. Examples of such networks are exchange networks, communication networks, disease transmission networks, control networks etc. For every symmetric network we define a cooperative transferable...

Collaboration in bipartite networks, with an application to coauthorship networks

Hsieh, Chih-Sheng; König, Michael D.; Liu, Xiaodong; … - 2020

This paper studies the impact of collaboration on research output. First, we build a micro-founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...
