Spontaneous Discrimination
研究在动态经济中，代理人基于物理颜色和社会颜色信号自发形成歧视性均衡的条件，对理解非经济因素导致的歧视行为有参考价值。
We consider a dynamic economy in which agents are repeatedly matched and decide whether or not to form profitable partnerships. Each agent has a physical color and a social color. An agent's social color acts as a signal, conveying information about the physical color of agents in his partnership history. Before an agent makes a decision, he observes his match's physical and social colors. Neither the physical color nor the social color is payoff relevant. We identify environments where equilibria arise in which agents condition their decisions on the physical and social colors of their potential partners. That is, they discriminate.
