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 … results that relate situations of positive externalities with stable networks that cannot be 'too dense' in a well …

and the implications for the structure of pairwise stable networks. First, different definitions of convexity (concavity … own links and strategic complements, a local uniqueness property of pairwise stable networks is derived. The results do …

We present a new approach to the study of networks where the formation of links is driven by unilateral initiative of … generalization of the model in which intermittent states can make the evolution of connectivity slower. In this class of networks … to a class of networks not based on the rationale of linking probability between pair of nodes, but it is based on the …
