Games Played on Networks

==Notes by yinung==
原本獨立的 game 在 linked network 玩會如何呢?
本文介紹了網路位置 (network position) 觀念, 及其對均衡的影響 (Ballester, CalvÛ-Armengol & Zenou (2006) Örst establish the connection between equilibrium action and Bonacich centrality (Bonacich 1987),另見 Yves Zenou.

This chapter studies games played on fixed networks. These games capture a wide variety of economic settings including local public goods, peer effects, and technology adoption. We establish a common analytical framework to study a wide game class. We unearth new connections between games in the literature and in particular between those with binary actions, like coordination and best-shot games, and those with continuous actions and linear best replies. We review and advance existing results by showing how they tie together within the common framework. We discuss the game-theoretic underpinnings of key notions including Bonacich centrality, maximal independent sets, and the lowest and largest eigenvalue. We study the interplay of individual heterogeneity and the network and we develop a new notion – interdependence – to analyze how a shock to one agent affects the action of another agent. We outline directions for future research.
