This paper provides a game-theoretic model of network formation with a continuous effort choice. Efforts are strategic … complements for direct neighbors in the network and display global substitution/congestion effects. We show that if the parameter … links according to a network cost function. Again all socially optimal configurations are such that the network is a nested …

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 …

By design, the Bitcoin protocol has a low throughput. The Lightning Network (LN) is a layer-two solution built to …

-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 …

I present a behavioural model of network formation with positive network externalities in which individuals have …

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 …

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.

In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors … in the network benefit from each other's action levels through local complementarities and there exists a global …
