Replication Data for: Risk Pooling, Risk Preferences, and Social Networks

Using data from an experiment conducted in 70 Colombian communities, we investigate who pools risk with whom when trust is crucial for enforcing risk pooling arrangements. We explore the roles played by risk attitudes and social networks. Both empirically and theoretically, we find that close friends and relatives group assortatively on risk attitudes and are more likely to join the same risk pooling group, while unfamiliar participants group less and rarely assort. These findings indicate that where there are advantages to grouping assortatively on risk attitudes those advantages may be inaccessible when trust is absent or low.本研究依托70个哥伦比亚社区的实验数据，针对风险共担（risk pooling）协议的执行高度依赖信任的场景，探究个体将与何人结成风险共担关系。本研究同时考察风险态度与社会网络在其中的作用。无论从实证还是理论维度，本研究均发现：至亲好友与亲属会依据风险态度进行同配性（assortative）分组，且更倾向于加入同一风险共担群体；而陌生参与者的分组概率更低，且极少发生同配行为。上述研究结果表明，若基于风险态度进行同配性分组存在收益优势，那么在信任缺失或信任水平低下的场景中，此类优势将难以获取。
