Whom should we believe? Aggregation of heterogeneous beliefs

We examine the collective risk attitude of a group with heterogeneous beliefs. We prove that the wealth-dependent probability distribution used by the representative agent is biased in favor of the beliefs of the more risk tolerant consumers. Moreover, increasing disagreement on the state probability raises the state probability of the representative agent. It implies that when most disagreements are concentrated in the tails of the distribution, the perceived collective risk is magnified. This can help to solve the equity premium puzzle. We show that the trade volume and the equity premium are positively correlated.

Americans are more exposed to difference than we think: Capturing hidden exposure to political and racial difference

Use of name generators (NG) in assessing exposure to political difference has led to the conclusion that disagreement is uncommon. Data from two representative surveys tested a NG modification to probe for exposure to difference. Over half for whom NG results suggest no exposure to difference were able to name an alter who supported an alternative candidate. Over a quarter whose NG results indicate no exposure to a racial difference were able to name someone of the opposite race with whom they’d talked politics. These findings demonstrate that mixed or diverse networks are more common than prior NG research suggests.     

中国古代对“两不和同”的法律规制:以买卖契约为例

中国古代契约实践对当事人"和同"意志的强调由来已久。法律对"两不和同"行为也进行了严格规制,禁止买卖契约中的"较固取"、"更出开闭"与"参市"等行为,这体现了对契约当事人自由意愿的尊重,并在很大程度上保障了契约自由。     

孔子反对"铸刑鼎"的法哲学解读

孔子对铸刑鼎的反对立场是没有疑问的,但对孔子反对铸刑鼎这一经验性事实的理论性解读却是争议不断的。放在孔子的整个思想体系去考察,孔子站在经验主义的立场上,对人的理性持审慎的怀疑态度,对单凭人的理性所制定的法典的质量并不乐观。这体现了孔子对自由秩序和良法的追求。孔子对铸刑鼎的反对观点自有其闪光的深刻之处,不能简单地定论为落后。
