In this paper, we connect the social network theory on centrality measures to the economic theory of preferences and … different networks. The famous degree measure assigns to every position in a weighted network the sum of the weights of all … links with its neighbours. A crucial property of a preference relation over network positions is neutrality to ordinary risk …

When workers send applications to vacancies they create a network. Frictionsarise because workers typically do not know … frictionaffects network formation, while the second coordination friction affects networkclearing. We show that those frictions and … arise and the number of matches on a given network. Equilibria that exhibitwage dispersion are inefficient in terms of …

that the individual's incentives depend on the architecture of the network as well as on the position of the individual … within the network. In particular, when an efficient interaction requires players to mutually cooperate, efficient social …

Agents involved in the formation of a social or economic network typically face uncertainty about the benefits of … creating a link. However, the interplay of such uncertainty and risk attitudes has been neglected in the network formation … literature. We propose a dynamic network formation model that builds on standard microeconomic concepts of utility maximization …
