AI 中文摘要
本文在有限状态的Anscombe-Aumann框架中发展了一个可识别的平滑模糊模型,在该框架中,模糊感知和模糊态度表示可能依赖于行为的内生确定性等价效用水平。该框架分离了标准平滑模糊模型所固定的效用水平依赖的两个来源。在揭示单元内的中性转移实验恢复了条件信念,而跨单元的补偿实验恢复了单元权重和局部揭示的模糊态度尺度。这些对象具有不同的行为内容。在水平内结构全局扩展后,模糊感知在每个确定性等价水平上被识别,而可容许的特定水平全局态度指数的变化本身不一定反映行为上识别的模糊态度变化。跨水平限制决定了局部揭示的态度尺度何时可以改为由一个共同的全局模糊态度指数表示。基线特征化产生了一个双重隐式平滑模糊表示,具有特定水平的感知和可能特定水平的全局态度指数。要求一个共同的模糊态度指数给出了一个中间稳定态度模型,其中只有感知可能变化;同时要求感知稳定性在维持全支持、中性分离、固定划分且至少有三个揭示单元的环境中产生了标准的可识别平滑模糊。因此,贡献在于将平滑模糊中效用水平依赖的行为分解为分别揭示的感知和态度组成部分。
英文摘要
This paper develops a model of identifiable smooth ambiguity in a finite-state Anscombe-Aumann framework in which ambiguity perception and the ambiguity-attitude representation may depend on the act's endogenous certainty-equivalent utility level. The framework separates two sources of utility-level dependence that standard smooth-ambiguity models hold fixed. Neutral-transfer experiments within revealed cells recover conditional beliefs, while compensation experiments across cells recover cell weights and locally revealed ambiguity-attitude scales. These objects have distinct behavioral content. After the within-level structure is extended globally, ambiguity perception is identified at each certainty-equivalent level, whereas variation in admissible level-specific global attitude indices need not by itself reflect behaviorally identified variation in ambiguity attitude. Cross-level restrictions determine when the locally revealed attitude scales can instead be represented by one common global ambiguity-attitude index. The baseline characterization yields a doubly implicit smooth-ambiguity representation with level-specific perception and potentially level-specific global attitude indices. Requiring one common ambiguity-attitude index gives an intermediate stable-attitude model in which only perception may vary; imposing perception stability as well yields standard identifiable smooth ambiguity within the maintained full-support, neutrally separated, fixed-partition environment with at least three revealed cells. The contribution is therefore a behavioral decomposition of utility-level dependence in smooth ambiguity into separately revealed perception and attitude components.
