Technical Analysis as a Rational Tool of Decision Making for Professional Traders

The psychological background of technical analysis usage is investigated to further explain the popularity and common usage of technical analysis as an investment decision tool. Attitudes toward technical analysis of professional futures market traders and neophyte investors, represented by finance students, were examined. Technical analysis is one of the most popular methods supporting investment decisions and it is much more popular among future market traders than among neophyte investors. The concept of processing information was used to explain this phenomenon. Neophyte investors are more experiential and intuition-driven while using technical analysis models, while futures market traders are more rationally driven. Technical analysis methods help professional traders on futures markets, which are less transparent than regulated stock markets, to process information; those methods are perceived by them as rational, cognitive tools supporting their decision making.

家族企业的“掏空”行为与会计盈余质量

以2003-2004年家族控制的上市公司为研究样本,实证考察了控制性家族的"掏空"行为对会计盈余质量的影响。研究结果表明,控制性家族的"掏空"行为加剧了公司内部人与外部投资者之间的信息不对称,降低了会计盈余的可靠性和价值相关性。上市公司的盈余管理程度与"掏空"行为显著正相关,会计盈余的信息含量与"掏空"行为显著负相关。     

风险分类对保险市场效率的影响分析

本文将社会福利作为衡量保险市场效率的标准,分析保险人的风险分类行为是否有助于信息不对称保险市场效率的提高.本文首先证明了信息不对称保险市场存在市场失灵,然后比较了实施风险分类前后社会福利的差异.结论表明:当保险市场处于R-S均衡时,准确性较高的分类能使社会福利得到改进,准确性不高的分类不能使社会福利得到改进;当保险市场...     

An integrated system for information security management with the unified framework

Information security management plays an essential role for drawing the roadmap of information security; thus, many theoretical methodologies and practical standards are brought into this domain. However, many standards and methodologies are too cumbersome to be adopted by an organization. Additionally, there is no unified framework to systematically handle the tedious tasks of information security management. This study’s primary goal is to design an integrated system for information security management (ISISM) that aims to use current methodologies and standards to solve the above-mentioned issues. Because business impact analysis and risk analysis are the most important areas within this domain, we carefully select the related methods and then integrate them into a unified framework, upon which the proposed ISISM depends. To achieve this outcome for this study, security requirement engineering is adopted, which enables the designed system to support system users in generating risk assessment reports with related information security policies.
