Replication Data for: \"Information Transmission in a Social Network: A Field Experiment\"

Using an app for smartphones, we run an experiment among high school students to study the pattern of aggregation of sparsely distributed information. Agents are randomly arranged in small networks and can share only non-verifiable pieces of information. Results show that while \textcolor{black}{information exchange} is high, the level and the distribution of centralities among network members are important to shape the overall level of information aggregation. A reduction in the asymmetry among agents’ network centralities is associated with an improvement in the performance of the group in terms of aggregation of information.本研究借助智能手机应用程序，面向高中生开展实验，以探究稀疏分布信息的聚合模式。智能体（Agents）被随机配置于小型网络内，仅可共享无法验证的信息片段。研究结果表明，尽管信息交换（information exchange）活跃度较高，但网络成员的中心性水平及其分布特征，对整体信息聚合水平具有重要塑造作用。实验主体间网络中心性的不对称程度降低，与群体在信息聚合任务中的表现提升显著相关。
