现代金融学理论的疏漏与分歧

基于理性人假设的有效市场理论认为证券价格总是可以充分反映可获得的信息。传统金融学的绝大多数研究领域,尤其是证券分析理论,都是在这一学说及其应用的基础上建立起来的。然而从上个世纪80年代开始,这一理论受到了空前的质疑,首先是来自噪音学派关于交易成本的批评,随后是来自行为金融学关于有限套利和噪音交易等更为严厉的质疑。本文从现代金融学理论的分歧入手,讨论资产价格决定因素的不同解释,分析了传统金融学与行为金融学的关系,认为有效市场理论与行为金融学两者本是同一理论体系的两个方面,相互补充和完善,而不是相互排斥。     

地方政府行为模式多样性的经济学分析

中国的市场化改革带来了经济领域的分权,导致各地方政府成为具有独立地位的利益主体,分别在特定的约束条件下追求自身的最大化利益。可以将地方政府界定为以地方党委主要领导为首的在地方事务中发挥核心作用的领导层,其在特定的约束条件下追求特定的利益目标。通过地方政府效能分配模型可以说明,不同地方政府由于面临约束条件的差别,产生了利益目标、追求目标方式等方面的差别,因而产生了多样化的地方政府行为模式。     

试论西周初期的“德”观念——以今文《周书》为中心的考察

周初之“德”是一个较为宽泛的观念,它可以分为以德配天、敬德保民、明德慎罚、任德尚贤四个重要组成部分,其价值与意义主要体现在政治领域,“德”是周人为论证政权的合法性及谋求政权的持久性而提出的。从内涵上来看,“德”字在周初尽管有了道德的意义,但“德”观念在人自身内在心灵的领域尚未达到深入的程度,“德”的外在意义在周初占有主导地位,它与后世具有普遍意义的个体心性道德还有一定的差距,并不等同于我们今天所说的“道德”。

Behavior Management of Client Contacts in a Real Estate Brokerage

A Project intended to increase client-contacting behavior on the part of 16 real-estate sales persons was described. Both contacts with prospective (initials) and with established clients (followups) were targeted for change. During a 20-week baseline, agent self-reports were used as a basis for posting weekly charts of contact behavior together with measured sales and listing performances. A conjunctive token-reinforcement procedure involving both contact behaviors was introduced during a 15 week intervention phase. For all agents as a group, a sustained increase in both behaviors was noted during this phase. Additional analyses revealed, however, that for low baseline performers, the intervention effect was only short-lived. During a subsequent three-week prewithdrawal stage, the increased behavion from the previous phase reverted nearly to baseline levels, despite the continued intervention, in response to instructions that program withdrawal was imminent. Contact behaviors further declined to below baseline levels during the following 4-week withdrawal stage when both posting and token procedures were actually discontinued. A tenninal 6 week reversal phase was marked by a nearly full recovery for all agents of asymptotic intervention levels of contact behavior under a reversed conjunctive token reinforcement schedule. Evidence indicating a correlation between changes in contact behaviors and changes in sales was presented. Also, other company benefits presumably derived from the program were described. Finally, the outcomes of this study were discussed in terms of several important validity concerns.     

Perceptions of efficacy in the use of contemporary film in social work education: An exploratory study

This article discusses the use of contemporary film in social work education, including the theoretical rationale for the inclusion of film from the perspective of narrative and adult learning theory as well as the application of the case method to the use of film. The student viewpoint and perspective is provided through the results of an exploratory research study with 109 Baccalaureate social work students who completed a survey questionnaire following a classroom activity involving a contemporary film. Analysis of the quantitative data and qualitative comments indicates that students believe that film is a beneficial adjunct to textbook and lecture content.

组织行为学发展的新领域——积极组织行为学

积极组织行为学是组织行为学科在21世纪才兴起的新的研究领域,由鲁森斯于2002年正式提出,强调对人类心理优势的开发与管理。与传统组织行为学将研究领域的重点放在解决管理者和员工的机能失调、冲突、工作压力等问题上所不同的是,积极组织行为学将研究重点放在如何采取积极的方法和怎样发挥员工优势以提高组织的绩效水平上。其研究范畴包括信心/自我效能、希望、乐观、主观幸福感、情绪智力等,具备积极性、独立性、可测量性、可开发性、有助于提高工作绩效等基本特征。
