Group Decision Making Under Conditions of Distributed Knowledge: The Information Asymmetries Model.
提出一个理论模型，解释为何群体成员间信息分布不均时，群体决策常未能有效利用这些信息，并指出在特定条件下群体可优于个体和投票机制。
We present a theoretical model that synthesizes and expands current explanations of the failure of decision-making groups to effectively use information that is distributed among their members. We propose that groups can outperform individual decision makers and voting schemes if certain asymmetries in information distribution are present and certain asymmetries in information processing are absent. How to achieve this we deduce from a review of the relevant literature. Finally, we discuss directions for future research and practical implications.
