价格促销对消费者品牌选择的影响研究

本文通过实验方法探索性地研究了价格促销对消费者品牌选择的非对称影响。研究表明:消费者对不同产品的价格敏感性有所不同;较贵重的笔记本电脑、手机等耐用消费品行业中的低端品牌在与高端品牌的短期价格竞争中会获得更多市场份额,而对较廉价的洗发水等非耐用消费品来说,高端品牌将会在降价促销时获益更多。本文研究结论与国外同类研究结论有所不同,对企业的定价决策有重要的理论指导意义。

A Theory of Rational Choice under Ignorance

This paper contributes to a theory of rational choice for decision-makers with incomplete preferences due to partial ignorance, whose beliefs are representable as sets of acceptable priors. We focus on the limiting case of `Complete Ignorance' which can be viewed as reduced form of the general case of partial ignorance. Rationality is conceptualized in terms of a `Principle of Preference-Basedness', according to which rational choice should be isomorphic to asserted preference. The main result characterizes axiomatically a new choice-rule called `Simultaneous Expected Utility Maximization'. It can be interpreted as agreement in a bargaining game (Kalai-Smorodinsky solution) whose players correspond to the (extremal) `acceptable priors' among which the decision maker has suspended judgment. An essential but non-standard feature of Simultaneous Expected Utility choices is their dependence on the entire choice set. This is justified by the conception of optimality as compromise rather than as superiority in pairwise comparisons.     

Choice Functions: Rationality re-Examined

On analyzing the problem that arises whenever the set of maximal elements is large, and a selection is then required (see Peris & Subiza 1998), we realize that logical ways of selecting among maximals violate the classical notion and axioms of rationality. We arrive at the same conclusion if we analyze solutions to the problem of choosing from a tournament (where maximal elements do not necessarily exist). So, in our opinion the notion of rationality must be discussed, not only in the traditional sense of external conditions (Sen 1993), but in terms of the internal information provided by the binary relation.     

组织职业生涯管理与工作卷入关系的研究

本研究以龙立荣开发的组织职业生涯管理问卷的简缩版和修订过的Kanungo的工作卷入问卷为测量工具,对多家企业的员工进行了调查。统计分析结果显示:组织职业生涯管理与员工的工作卷入之间存在显著的正相关关系,组织职业生涯管理中的各个维度与员工工作卷入的相关关系均达到了显著性水平,其中与员工工作卷入相关性最大的是“晋升公平”,相关性最小的是“注重培训”。此研究证明了组织职业生涯管理的必要性。     

社会网络对企业管理人员职业生涯成功影响的实证研究

本文从社会网络的角度出发,基于社会交换理论,建立了社会网络对企业管理人员职业生涯成功的作用模型,并指出社会网络对职业成功两者之间的关系是通过网络利益(资源和职业支持)的中介作用实现的.本文以407位企业管理人员为研究对象,采用结构方程模型对假设模型进行检验,研究结果验证了网络利益(资源和职业支持)的中介效应.研究同时得出,社会网络各指标会对网络利益产生影响.相对于网络规模和网络异质性,网络密度和关系强度对于网络利益的获取有更为重要的影响.在网络利益对职业生涯成功作用的过程中,网络资源仅对管理人员职业满意度产生显著的正向影响,而职业支持对管理人员的职业生涯成功各指标都有显著的影响.文章最后指出了研究的局限性和未来研究方向.     

Data-Driven Model Choice in Multivariate Nonparametric Regression

The problem of choosing between different regression models, is investigated. A completely automatic model selection procedure is defined and asymptotic optimality results are shown. These results are stated in a general framework including as well nested as unnested situations, including as well i.i.d. as dependent samples, and without specifying any class of non-parametric smoothers. Because of the well-known curse of dimensionality, model selection is of particular interest in multivariate regression settings, and it will be discussed how the previous general model choice approach can be used in several different highdimensional situations.     

Behavioral implications of providing real incentives in stated choice experiments

This paper explores the potential impacts of introducing real economic incentives in choice experiments (CE). While many others have investigated such impacts before, the majority of the literature has focused solely on mitigation of hypothetical bias. We contribute to this literature by widening the scope of research to other behavioral aspects where consumers in CE are often found to deviate from homo economicus. We develop a theoretical model where not only Willingness to pay (WTP) measures but also decision processing can be affected by the introduction of an economic incentive. Specifically, our model allows for differential impacts on attribute processing, depending on the character of the attribute as well as self-image effects. In an empirical CE survey, we find some, though not unequivocal, support of our model. Even though we find no impact on WTP from introducing an economic incentive, we find marked benefits in relation to a number of behavioral aspects that together would favor the use of an economic incentive regardless of hypothetical bias being present or not.
