Group Size as Selection Device
在存在多个帕累托排序均衡和人口不确定性的协调博弈中，群体规模有助于选出唯一均衡，类似于全局博弈文献中的机制，且均衡时出现临界质量现象，群体规模对参与者有激励作用。
Abstract In a coordination game with multiple Pareto ordered equilibria and population uncertainty, we show that group size helps select a unique equilibrium, for reasons reminiscent of the global games literature. A critical mass phenomenon emerges at equilibrium. Group size has an emboldening effect on participants.
