摘要:

时间结构化的私人和社会信息如何塑造集体决策?为了解决这个问题,我们考虑一个理性代理网络,这些代理独立地积累私人证据,这些证据在达到阈值时触发决策。当被整个网络看到时,第一个代理的选择会引发一波新的决策;后来的决策影响较小。在异质网络中,冲动的个体会很快做出第一个决定,他们几乎不需要证据就能做出选择,但即使是错误的,也能向几乎所有人揭示正确的选择。我们的结论是,不同的个人组成的群体可以比同质的更有效的决策。

英文摘要:

How does temporally structured private and social information shape collective decisions? To address this question we consider a network of rational agents who independently accumulate private evidence that triggers a decision upon reaching a threshold. When seen by the whole network, the first agent's choice initiates a wave of new decisions; later decisions have less impact. In heterogeneous networks, first decisions are made quickly by impulsive individuals who need little evidence to make a choice, but, even when wrong, can reveal the correct options to nearly everyone else. We conclude that groups comprised of diverse individuals can make more efficient decisions than homogenous ones.
