信息模糊：消费决策领域中的有限理性

信息模糊（obfuscation）是行为经济学研究的重要领域,主要解释了在商品买卖过程中,销售商通过把商品信息复杂化等手段,让人们的消费过程变得更加复杂和困难,从而使消费者在购买商品时面对信息模糊做出种种不明智的选择的现象问题。本文从以往的研究成果出发,就信息模糊、有限理性和销售者的决策行为的关系进行了探讨,以期为信息模糊的跨学科研究提供可借鉴的思路和方法。     

The CEO Selection Decision Process: Bounded Rationality and Decision Component Ordering

This paper presents a model of the basic components of the CEO selection decision process used by corporate boards of directors. It describes selection as a purposeful and boundedly rational process characterized by three key components: aspiration, judgment and justification. Each of these components is described in detail. In addition, the ordering of these elements is examined. Specifically, it is suggested that the exact ordering varies depending on a number of factors. Among the most important are (1) the performance of the organization, (2) the availability of qualified candidates and (3) the standardization of the CEO's office within the organization at the time of the succession decision. Examples are provided to help illustrate various order effects. Following this, sample research propositions are presented to assist researchers in future studies devoted to this topic.     

行为决策研究的新取向——基于经验的决策

基于经验的决策是指,在统计概率情境中,个体通过重复选择与反馈获得选项的收益分布信息后进行的决策.基于经验的决策的研究范式主要包括探索-利用范式和探索→利用范式.其暗含的决策人假设是朴素直觉统计学家.其研究关注的主要内容是描述-经验的差异及其原因,以及基于经验的决策内部过程.未来的研究主要从描述-经验差异的原因、描述性决策范式下的结论的重新检验、基于经验的决策的解释模型及其应用研究等方面进行探讨.     

"Leaky" Rationality: How Research on Behavioral Decision Making Challenges Normative Standards of Rationality

ABSTRACT— For more than 30 years, decision-making research has documented that people often violate various principles of rationality, some of which are so fundamental that theorists of rationality rarely bother to state them. We take these characteristics of decision making as a given but argue that it is problematic to conclude that they typically represent departures from rationality. The very psychological processes that lead to "irrational" decisions (e.g., framing, mental accounting) continue to exert their influence when one experiences the results of the decisions. That is, psychological processes that affect decisions may be said also to "leak" into one's experience. The implication is that formal principles of rationality do not provide a good enough normative standard against which to assess decision making. Instead, what is needed is a substantive theory of rationality—one that takes subjective experience seriously, considers both direct and indirect consequences of particular decisions, considers how particular decisions fit into life as a whole, and considers the effects of decisions on others. Formal principles may play a role as approximations of the substantive theory that can be used by theorists and decision makers in cases in which the formal principles can capture most of the relevant considerations and leakage into experience is negligible.     

Escalating Commitment in Individual and Group Decision Making: A Prospect Theory Approach

An explanation for escalating commitment based on prospect theory (Kahneman & Tversky, 1979) is extended to the group level of analysis. Hypotheses concerning the likelihood and degree of escalating commitment of individuals and groups were derived from the model and tested using six investment decision scenarios. Subjects responded to decision dilemmas in which substantial funds have been invested in a failing course of action. Subsequent investment would likely exacerbate although it could potentially reverse the situation. Consistent with hypotheses derived from the model, escalating commitment occurred in both individual and group decision making. Group decision making amplified trends apparent at the individual level in terms of the frequency with which escalation occurred and its severity. Although the results are consistent with a prospect-theory-based explanation of escalating commitment at two levels of analysis, support for the self-justification approach was also found. Motives for self-justification, however, do not appear to be a necessary condition for escalation to occur.     

The Theory and Practice of Foreign Policy Decision Making

Central to Alex George's work was a concern with the psychology of presidential decision making. Our analysis focuses on George's work at the intersection of leadership psychology and the psychology of judgment in the making of consequential foreign policy decisions, specifically those dealing with issues of war and peace. We begin with a review of the fundamental dilemmas of political decision making, focusing on the various factors that present challenges to leaders seeking to make high-quality decisions. We then move to an analysis of the nature of judgment and the ways in which it both shapes and is shaped by cognitive dynamics and conclude by examining a number of steps designed to help leaders avoid the most damaging blind spots of their own psychologies and cognitive biases.     

基于预期理论的风险决策的神经机制

预期理论基于对期望效用理论的批判与发展,提出了价值函数与权重函数,对以往风险决策研究中所发现的现象进行了很好的预测与解释。预期理论的核心概念包括参照依赖、损失规避与权重函数。基于预期理论的一些决策偏差包括框架效应、禀赋效应和默认偏差也部分揭示了与人们风险决策有关的脑区。近年来,通过采用功能性核磁共振等脑成像手段对预期理论的一些核心成分进行的研究表明,涉及到人们风险决策的脑区主要有前额叶、纹状体、脑岛与杏仁核。未来的研究可以从预期理论的产生根源、个体发展以及遗传基因等角度进行进一步的探讨。
