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, we combine a network game introduced by Ballester...

R&D networks : theory, empirics and policy implications

König, Michael D.; Liu, Xiaodong; Zenou, Yves - 2014 - This version: February 7, 2014

We study a structural model of R&D alliance networks in which firms jointly form R&D collaborations to lower their production costs while competing on the product market. We derive the Nash equilibrium of this game, provide a welfare analysis and determine the optimal R&D subsidy program that...

Social Norms in Networks

Ushchev, Philip - 2019

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this study, we develop a social-norm model that provides a microfoundation of the linear-in-means model and investigate its properties. We show that...

Coordination on Networks

Leister, C. Matthew - 2019

We study a coordination game among agents on a network, who choose whether or not to take an action in an uncertain environment that yields value increasing in the actions of neighbors. We develop an algorithm that fully characterizes the equilibrium partitions (coordination sets) and thresholds...

Conflicts in Spatial Networks

Amarasinghe, Ashani; Raschky, Paul; Zenou, Yves; Zhou, … - 2020

We develop a network model of conflict in which players are involved in different battles. A negative shock in one locality affects the conflict in this locality but may also increase battles in path-connected localities depending on the location of the battle in the network and the strength of...

Social Norms in Networks

Ushchev, Philip - 2018

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this paper, we investigate how social norms affect individual effort, aggregate effort, and welfare. While individual productivity always positively...

Community Formation in Networks

bochet, olivier; Ferrali, Romain; Zenou, Yves - 2022

We study a strategic model of community formation on networks. Starting from a seed community member, the process of … community formation is sequential, with infinitely-patient and forward-looking agents making strategic offers to their neighbors …. Each agent makes an irreversible binary choice, and each time she accepts an offer, she joins the community. For arbitrary …

Spillovers in criminal networks : evidence from co-offender deaths

Lindquist, Matthew J.; Patacchini, Eleonora; … - 2024

We study spillover effects within co-offending networks by leveraging deaths of co-offenders for causal identification. Our results demonstrate that the death of a co-offender significantly reduces the criminal activities of other network members. We observe a decaying pattern in the magnitude...

Nestedness in networks: A theoretical model and some applications

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

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...
