Maintaining the security of critical infrastructure networks is vital for a modern economy. This paper examines a game …-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 …

network formation. We model a network where good/green firms enjoy direct and indirect benefits from linking with one another … connections. In efficient networks the green firms should form large connected components with very few brown firms attached. The … equilibrium networks, on the other hand, have many more brown firms attached, and components are also smaller than the efficient …

networks, such coordination may be very difficult to achieve and may depend on the communication technology and the network … structure. We examine how pre-play communication and clustering within networks affect coordination in a challenging … experimental game on eight-person networks. Free-form chat is enormously effective in achieving the non-equilibrium efficient …
