Cognitive Ability, Character Skills, and Learning to Play Equilibrium: A Level-kAnalysis
通过实验研究认知能力和性格技能如何影响人们在重复策略互动中向纳什均衡的演化，发现认知能力更强的被试更接近均衡、收益更高且更频繁收敛到均衡，同时性格中的宜人性和情绪稳定性也促进学习。
We investigate how cognitive ability and character skills influence the evolution of play toward Nash equilibrium in repeated strategic interactions. We find that more cognitively able subjects choose numbers closer to equilibrium, earn more, and converge more frequently to equilibrium play. We estimate a structural model of learning based on level k reasoning and find a positive relationship between cognitive ability and levels. Furthermore, the average level of more cognitively able subjects responds positively to the cognitive ability of their opponents. More agreeable and emotionally stable subjects also learn faster, although the effect of cognitive ability is stronger than that of personality.
