金融学中的技术分析理论基础研究综述

虽然技术分析在金融实业界得到了广泛的关注和应用,但是金融学术界却较少关注它,原因在于技术分析认为价格可以预测,而这与有效市场假说是背道而驰的。然而,金融学者通过对新古典金融理论的修正,建立了基于信息不对称的噪音理性预期模型和基于行为金融学的正反馈模型,为技术分析提供了理论支持。此外,其他理论模型从市场摩擦、羊群效应、市场影响力等角度出发,也证明了技术分析的有效性。

Accounting for optimism and pessimism in expected utility

We provide a preference foundation for decision under risk resulting in a model where probability weighting is linear as long as the corresponding probabilities are not extreme (i.e., 0 or 1). This way, most of the elegance and mathematical tractability of expected utility is maintained and also much of its normative foundation. Yet, the new model can accommodate the extreme sensitivity towards changes from 0 to almost impossible and from almost certain to 1 that has widely been documented in the experimental literature. The model can be viewed as “expected utility with the best and worst in mind” as suggested by Chateauneuf, Eichberger and Grant (Chateauneuf, Alain, Eichberger, Jürgen, Grant, Simon, 2007. Choice under uncertainty with the best and worst in mind: NEO-Additive capacities. Journal of Economic Theory 137, 538–567) or, following our preference foundation, interpreted as “expected utility with consistent optimism and pessimism”.

Measuring the Quality of Life in the Workplace （QLW） Through Job Diagnostic Survey （JDS）： Comparative Study on Two Legal Nature Differentiated Organizations

The article presents a theoretical-empirical reflection about concepts, models, and practices of Quality of Life at Work （QLW） in organizations of different legal nature. The initial proposition of the research suggested that private organizations, that are more susceptible to competitive pressures in the market for resources and the uncertainties regarding the employability tend to have worse indicators of QLW than the public organizations that exhibit greater control over their influx of resources and greater stability in jobs that are offered. The literature review included the concepts and models of QLW as well as the characteristics and application methodology of the Job Diagnostic Survey （JDS）, and your score on Task Motivational Potential （TMP）, as instruments of evaluating the dimensional indicators of QLW in organizations. In methodological terms, we proceeded to a multiple case study comparative, supported by the application of the reduced version of JDS, through its questionnaire that has already been validated in previous studies in two organizations, a private foundation supporting university and a public company of electricity supply, both located in the State of Amazonas-Brazil. The research findings using the JDS instrument indicated failed to detect significant differences between the scores of TMP between the two organizations, nor any robust correlation between their respective legal personalities and environments of institutional performance. Nevertheless, the small differences found suggest a framework of indicators of QLW slightly more favorable to the foundation of university support.
