Peer Advice on Financial Decisions: A Case of the Blind Leading the Blind?
通过实验室实验，研究同伴互动如何影响财务决策质量，发现面对面交流能显著改善后续私人决策，且技能弱者与弱者配对学习效果最佳。
Abstract We investigate the impact of peer interaction on the quality of financial decision making in a laboratory experiment. Face-to-face communication with a randomly assigned peer significantly improves the quality of subsequent private decisions even though simple mimicry would have the opposite effect. We present evidence that the mechanism involves general conceptual learning (because the benefits of communication extend to previously unseen tasks), and that the most effective learning relationships are horizontal rather than vertical (because people with weak skills benefit most when their partners also have weak skills). The benefits of demonstrably effective financial education do not propagate to peers.
