Under-connected and over-connected networks

Buechel, Berno; Hellmann, Tim - 2008

Since the seminal contribution of Jackson & Wolinsky 1996 [A Strategic Model of Social and Economic Networks, JET 71, 44-74] it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has...

Convexity and complementarity in network formation: Implications for the structure of pairwise stable networks

Hellmann, Tim - 2009

This paper studies the properties of convexity (concavity) and strategic complements (substitutes) in network formation … shown that there always exists a pairwise stable network as long as the utility function of each player satisfies convexity … in own links and strategic complements. For network societies with a profile of utility functions satisfying concavity in …
