Equilibria with Communication in a Job Market Example
研究求职者与雇主之间无成本信息传递的均衡，发现至少需要两步信号或无限期对话才能实现某些均衡，且借助沟通设备可扩大均衡收益集。
We study (costless) information transmission from a job applicant to an employer who must decide whether to hire him and, if so, which position to give him. We construct equilibrium payoffs requiring at least two signaling steps, or even that no deadline be imposed on the (plain) conversation. The set of communication equilibrium payoffs (achieved with the help of a communication device) is larger than the set of equilibrium payoffs of the plain conversation game but coincides with the set of correlated equilibrium payoffs.
