Trust and Diversity : A Game Theoretic Approach to Social Norms in a Voluntary Transaction Society

我们研究了信任和社会规范如何在自愿分离的囚徒困境模型中发挥作用。我们已经证明，使用参考字母的昂贵和自愿的信息传输提高了均衡效率。我们还证明了，当一定条件成立时，既包含合作策略又包含非合作策略的均衡比只包含合作策略的均衡更有效。

We studied how trust and social norms work in the voluntarily separable Prisoner's Dilemma models. We have shown that costly and voluntary information transmission using reference letters improves equilibrium efficiency. We also have shown that, when a certain condition holds, equilibrium involving both cooperative and non-cooperative strategies is more efficient than equilibrium with cooperative strategies only.
