提出 Menger 概率赋范线性空间上集合有界性的简化定义,利用 Menger概率赋范空间的线性拓扑性质,在较弱的 t-模条件下,建立了概率有界、概率半有界、非概率无界意义下线性算子的共鸣定理。     

考虑消费者有限理性的体验式商品订购与库存配给策略

退货遗忘与缺货后悔是消费者在现实中普遍存在的有限理性行为。在考虑这两种有限理性行为以及销售商提供无理由退款承诺的基础上,构建了一个两期模型对体验式商品的订购与库存配给策略进行了分析。研究得到如下结论：首先,只有当产品价值的上界大于某个临界值时,消费者才会在两个销售期内购买产品,销售商应该采取库存配给策略以应对消费者的策略行为;其次,销售商的收益随着消费者满意概率、退货遗忘率和缺货后悔程度的增大而增大。数值分析表明：当消费者满意概率或产品满足率感知偏差较大时,消费者策略行为的负面影响在一定程度上得到减轻;虽然有限理性总是可以提高销售商的收益,但是退货遗忘与缺货后悔对销售商收益增长的影响作用是不同的。

A dynamic and cyclical model of bounded ethicality

We introduce a new model of bounded ethicality which helps explain three persistent puzzles of ethical behavior: when moral awareness is or is not present, when ethical behavior is more or less consistent with past behavior, and when blind spots obscure our ethical failures. The original conception of bounded ethicality (Chugh, Banaji, & Bazerman, 2005) described the systematic psychological constraints on ethical behavior and has contributed to our field's understanding of the phenomena of everyday, “ordinary” unethical behavior. In this more detailed model, we delineate these systematic processes and mechanisms and show how concepts of automaticity, self-view, and self-threat play critical roles in our ethical decision-making. The model describes distinct, asymmetric patterns of (un)ethical behavior and pinpoints the contingency which determines which pattern is more likely to unfold, including when we will trend to more or less automaticity and more or less ethical behavior. Our model integrates and synthesizes many of the key models and findings in recent behavioral ethics research into a single, overarching model of ethical decision-making, offering an anchor for new questions and a new realm of study.     

基于有限理性的投资项目评价与决策研究

现行的项目经济评价方法的隐含假设,是古典经济学的“完全理性”。但现实中的人做不到完全理性。西蒙从心理学角度提出了“有限理性”假说。项目评价与决策的有限理性有多种表现。决策的三要素——目标、方案、决策行为,都很大程度地受到有限理性的影响,并会导致一定的决策效果偏差。有限理性对于不同类型项目的影响方式又有着重要的差异。为应对有限理性的消极影响,应对决策活动进行一些规制：首先,调整决策预期和决策行为,既然最优选择可遇不可求,能够获得满意方案即可;其次,在决策方式上,灵活地采取诸如群体决策、集中／分散决策、柔性决策等方式,来尽量消除有限理性的影响。     

“Take-the-Best” and Other Simple Strategies: Why and When they Work “Well” with Binary Cues

The effectiveness of decision rules depends on characteristics of both rules and environments. A theoretical analysis of environments specifies the relative predictive accuracies of the “take-the-best” heuristic (TTB) and other simple strategies for choices between two outcomes based on binary cues. We identify three factors: how cues are weighted; characteristics of choice sets; and error. In the absence of error and for cases involving from three to five binary cues, TTB is effective across many environments. However, hybrids of equal weights (EW) and TTB models are more effective as environments become more compensatory. As error in the environment increases, the predictive ability of all models is systematically degraded. Indeed, using the datasets of Gigerenzer et al. (1999, Simple Heuristics That Make Us Smart, New York: Oxford University Press), TTB and similar models do not predict much better than a naïve model that exploits dominance. Finally, we emphasize that the results reported here are conditional on binary cues.
