Iijima, Ryota; Kamada, Yuichiro - In: Theoretical Economics 12 (2017) 2, pp. 655-689

This paper proposes a tractable model that allows us to analyze how agents' perception of relationships with others determines the structures of networks. In our model, agents are endowed with their own multidimensional characteristics and their payoffs depend on the social distance between...

A model of weighted network formation

Baumann, Leonie - In: Theoretical Economics 16 (2021) 1, pp. 1-23

possibly different intensities with other agents and to use for private purposes. We show that every equilibrium is either … "reciprocal" or "non-reciprocal". In a reciprocal equilibrium, any two agents invest equally in the link between them. In a non …-reciprocal equilibrium, agents are partitioned into "concentrated" and "diversified" agents and a concentrated agent is only linked to …

Nestedness in networks: A theoretical model and some applications

Zenou, Yves; König, Michael D.; Tessone, Claudio J. - In: Theoretical Economics 9 (2014) 3, pp. 695-752

We develop a dynamic network formation model that can explain the observed nestedness in real-world networks. Links are formed on the basis of agents' centrality and have an exponentially distributed life time. We use stochastic stability to identify the networks to which the network formation...

The formation of networks with local spillovers and limited observability

König, Michael David - In: Theoretical Economics 11 (2016) 3, pp. 813-863

This paper analyzes the formation of networks in which each agent is assumed to possess some information of value to the other agents in the network. Agents derive payoff from having access to the information of others through communication or spillovers via the links between them. Linking...

On Groves mechanisms for costly inclusion

MacKenzie, Andrew; Trudeau, Christian - In: Theoretical Economics 18 (2023) 3, pp. 1181-1223

We investigate Groves mechanisms for economies where (i) a social outcome specifies a group of winning agents, and (ii) a cost function associates each group with a monetary cost. In particular, we characterize both (i) the class of cost functions for which there are Groves mechanisms such that...
