Intermediation in networks
Siedlarek, Jan-Peter - 2014
I study intermediation in networked markets using a stochastic model of multilateral bargaining in which traders compete on different routes through the network. I characterize stationary equilibrium payoffs as the fixed point of a set of intuitive value function equations and study efficiency...

A Dynamic Model of Network Formation with Strategic Interactions
Koenig, Michael - 2010
In order to understand the different characteristics observed in real-world networks, one needs to analyze how and why … networks form, the impact of network structure on agents' outcomes, and the evolution of networks over time. For this purpose … real-world networks. We also find that there exists a sharp transition in efficiency and network density from highly …

Games on Networks
Jackson, Matthew O.; Zenou, Yves - 2014
We provide an overview and synthesis of the literatures analyzing games in which players are connected via a network structure. We discuss, in particular, the impact of the structure of the network on individuals' behaviors. We focus on game theoretic modeling, but also include some discussion...

The formation of networks with transfers among players
Bloch, Francis; Jackson, Matthew O. - 2004
We examine the formation of networks among a set of players whose payoffs depend on the structure of the network. We … links. We characterize the networks that are supported under these variations and show how each of the above aspects is …

Games on networks : direct complements and indirect substitutes
Currarini, Sergio; Fumagalli, Elena; Panebianco, Fabrizio - 2013
Many types of economic and social activities involve significant behavioral complementarities (peer effects) with neighbors in the social network. The same activities often exert externalities that cumulate in "stocks" affecting agents' welfare and incentives. For instance, smoking is subject to...

Network effects and research collaborations
Essers, Dennis; Grigoli, Francesco; Pugacheva, Evgenia - 2020
We study the determinants of new and repeated research collaborations, drawing on the coauthorship network of the International Monetary Fund (IMF)'s Working Papers series. Being an outlet where authors express their views on topics of interest, and given that IMF staff is not subject to the...

Communication with tokens in repeated games on networks
Wolitzky, Alexander - In: Theoretical economics : TE ; an open access journal in … 10 (2015) 1, pp. 67-101
A key obstacle to coordination and cooperation in many networked environments is that behavior in each bilateral relationship is not observable to individuals outside that relationship: that is, information is local. This paper investigates when players can use communication to replicate any...

Formation of Decentralized Two-Sided Networked Market
Shirata, Yasuhiro - 2015
This paper examines stability and efficiency of the Walrasian equilibrium outcome in a decentralized two-sided networked market, where any pair of a buyer and a seller must be connected by a link to engage in trading. In this networked market, buyers and sellers first form a network and then...

Under-connected and over-connected networks
Buechel, Berno (contributor); Hellmann, Tim (contributor) - 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 … results that relate situations of positive externalities with stable networks that cannot be "too dense" in a well …
