摘要翻译：
研究了不确定条件下的跨期决策问题。我们在一个框架中充分刻画了期望效用的折现。尽管该模型很受欢迎，但在此设置中没有可用的特征描述。由Koopmans提出的确定性效用折现的平稳性概念，对于对待时间和不确定性的态度都起着核心作用。我们证明了一个强平稳性公理刻画了折扣期望效用。当考虑套期保值时，一个较弱的平稳性公理将贴现预期效用推广为Choquet贴现预期效用，允许对不确定性的非中性态度。

英文摘要：
We study intertemporal decision making under uncertainty. We fully characterize discounted expected utility in a framework \`a la Savage. Despite the popularity of this model, no characterization is available in this setting. The concept of stationarity, introduced by Koopmans for deterministic discounted utility, plays a central role for both attitudes towards time and towards uncertainty. We show that a strong stationarity axiom characterizes discounted expected utility. When hedging considerations are taken into account, a weaker stationarity axiom generalizes discounted expected utility to Choquet discounted expected utility, allowing for non-neutral attitudes towards uncertainty.
