Linking decisions are based on network-dependent marginal payoff and a … network independent noise capturing exogenous idiosyncratic effects. Moreover, agents have a limited observation radius when …

Information sharing in oligopoly : sharing groups and core-periphery architectures
Currarini, Sergio; Feri, Francesco - In: Games 12 (2021) 4, pp. 1-17
The trade-off between the costs and benefits of disclosing a firm's private information has been the object of a vast literature. The absence of incentives to share information on a common market demand prior to competition has been advocated to interpret information sharing as evidence of...

Social distance and network structures
Iijima, Ryota; Kamada, Yuichiro - In: Theoretical economics : TE ; an open access journal in … 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...

Chain stability in trading networks
Hatfield, John William; Kominers, Scott Duke; Nichifor, … - In: Theoretical economics : TE ; an open access journal in … 16 (2021) 1, pp. 197-234
In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept that plays the same role as pairwise stability in two-sided settings. We show that chain stability is equivalent to stability if all agents' preferences are jointly fully...

On information aggregation and interim efficiency in networks

Locally Bayesian learning in networks
Li, Wei; Xu Tan - In: Theoretical economics : TE ; an open access journal in … 15 (2020) 1, pp. 239-278
Agents in a network want to learn the true state of the world from their own signals and their neighbors' reports … the (possibly misspecified) prior belief that her local network is the entire network. We present a tractable learning … reports in her local network. Despite their limited network knowledge, agents learn correctly when the network is a social …

We study a sequential-learning model featuring a network of naive agents with Gaussian information structures. Agents …' actions in terms of network paths and use this formula to characterize the set of networks where naive agents eventually learn … expected welfare losses, across network structures.
