No Man is an Island: Social Coordination and the Environment
建立了一个社会协调与环境外部性的简化模型，探讨了网络效应和社会压力如何导致环境友好或破坏的自我强化循环，并讨论环境政策如何帮助人们转向更环保的协调方式。
Abstract Humans are fundamentally social. Social activities require coordination, possibly leading to multiple equilibria in the form of self-reinforcing patterns of herd behavior. When alternative equilibria differ substantially with respect to environmental damage, they represent virtuous and vicious cycles from an environmental perspective. Such cycles can be sustained by network effects, social pressure to conform, or other mechanisms directly or indirectly yielding coordination benefits. Breaking the vicious cycles can be an important task for environmental policies. I present a stylized model of social coordination with environmental externalities, using it to discuss how environmental policies may help agents coordinate in more environment-friendly ways.
