集体模糊态度对个体模糊态度与信念分歧的回应
Collective ambiguity attitude as response to individuals’ ones and belief disagreements
摘要
This paper axiomatically characterizes the rule of aggregating individuals’ ambiguous beliefs into the society’s ambiguous belief. We consider a family of social rankings over acts which are indexed by pairs of utility profiles and ambiguous belief profiles, and impose variable-profile axioms which express how society should respond to changes in belief profiles and changes in how beliefs disagree. Our characterization allows two kinds of collective ambiguity aversion, one arising due to individuals’ ambiguity aversion and the other arising due to disagreements in beliefs.

本文公理化地刻画了将个体模糊信念聚合为社会模糊信念的规则。我们考虑一族关于行为的社会排序，这些排序由效用剖面与模糊信念剖面的配对来索引，并施加可变剖面公理，以表达社会应如何回应信念剖面的变化以及信念分歧方式的变化。我们的刻画允许两种集体模糊厌恶：一种源于个体的模糊厌恶，另一种源于信念分歧。
