利用在 70 个哥伦比亚社区进行的一项实验的数据，我们调查了当信任对于执行风险分担安排至关重要时，谁与谁分担风险。我们探讨了风险态度和社交网络所扮演的角色。从经验和理论上来看，我们发现亲密的朋友和亲戚在风险态度上存在不同的分组，并且更有可能加入同一风险分担小组，而不熟悉的参与者则较少且很少进行组合。这些发现表明，在风险态度上进行分类分组具有优势的地方，当信任缺失或信任度较低时，这些优势可能无法获得。 （JEL C93、O12、O18、Z13）
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. (JEL C93, O12, O18, Z13)
