Local Network Effects and Complex Network Structure
Sundararajan, Arun - 2014
This paper presents a model of local network effects in which agents connected by a social network each value the …-Nash equilibria of this network game are in monotone strategies, can be strictly Pareto-ranked based on a scalar neighbor … which the social network is an instance of a Poisson random graph, when it is a complete graph, a standard model of network …

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,...

The price of anarchy for network formation in an adversary model
Kliemann, Lasse - In: Games 2 (2011) 3, pp. 302-332
We study network formation with n players and link cost α > 0. After the network is built, an adversary randomly …

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...

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...

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 …

The Optimal Defense of Network Connectivity
Kovenock, Dan; Roberson, Brian - 2016
-theoretic model of attack and defense of a network in which the defender's objective is to maintain network connectivity and the … attacker's objective is to destroy a set of nodes that disconnects the network. The conflict at each node is modeled as a … which a single random [minimal] set of nodes that disconnects the network is attacked …

Network Comparative Statics
Harkins, Andrew - 2021
This paper develops a framework for analyzing the effect of arbitrary changes to network structure in linear …-quadratic games on networks. Changes to network structure which increase total activity and total utility are studied for the case of … centrality which counts the total length of walks from a node.Two optimal network design problems are then considered. Total …
