Three tests for the skewness of an unknown distribution are derived for iid data. They are based on suitable normalization of estimators of some usual skewness coefficients. Their asymptotic null distributions are derived. The tests are next shown to be consistent and their power under some sequences of local alternatives is investigated. Their finite sample properties are also studied through a simulation experiment, and compared to those of the √ b 2-test.  相似文献

外推型预期公式的检验与评价   总被引:1,自引:0,他引:1  
陈昭 《商业研究》2003,(7):24-26
经济学中的很多变量需要预测,其中的一个方法是运用外推型预期公式。由于外推型预期公式有 其自身特点和规律,即趋势值的选择是影响预测效果的一个主要变量,因此使用该公式进行经济预测时, 短期预测应选择较小的趋势值,长期预测应选取中间的趋势值。  相似文献

This article examines judicial and administrative rulings and legislation involving or related to the issue of drug testing in the workplace. It discusses the rights of employees in the public and private sector: constitutional rights; federal, state, and local statutory rights; rights of unionized employees; and common law rights. It analyzes both the current state of the law and future directions the law may take, as courts and administrative agencies decide more cases and governmental bodies continue to pass drug testing legislation.  相似文献

社会主义和谐社会建设作为我们全面建设小康、加快推进现代化事业的一项战略任务和重要内容,已经被提上了重要议事日程。而社会的和谐稳定、民众的共同富裕,都离不开社会阶层结构的优化、中等收入者阶层的不断扩大。为此,需要我们以科学发展观总揽改革发展全局,从多方面入手,努力塑造“橄榄型”的阶层结构模式。  相似文献

This paper investigates the phenomenon of judicial corruption and incorporates it into Polinsky, A. M. (1980). Strict liability vs. negligence in a market setting. American Economic Review, 70, 363–367 framework so as to analyze the efficiency of the negligence rule. By shedding light on the role of social norms in regard to the phenomenon of judicial corruption, this analysis provides implications for policy. First, more prevalent corruption at the status quo tends to intensify the extent of the corruption itself and, as a result, the effectiveness of the government’s corruption enforcement is greatly lessened. This implies that an excessively lenient policy of corruption may result in an uncontrollable consequence; once corruption becomes rampant, it is costly to bring it down. Of great importance, in the presence of such a corruption effect, the social optimum cannot be achieved based on the negligence rule and the equivalence between the strict liability and negligence rule fails. Secondly, the attitude of the society toward a corrupt judge plays a crucial role in governing the effectiveness of an efficient wage arrangement. If the society can fully accept a corrupt judge, corruption will never be controlled even with the incentive wage scheme.

To determine the various performance criteria concerning journalism it is reasonable to develop a broad concept, which integrates the different theoretical approaches. In a functional and system-oriented perspective, fundamental performance criteria can be based on the social function and the specific code of journalism, which emerged in an historical process of mutual observation of journalists and audiences. In a normative-democratic perspective, performance criteria can be derived from societal and human values codified in diverse regulations. However, in this regard it has to be taken into account that specific claims of the political subsystem also play an important role. Finally from an audience and action oriented viewpoint, it is important to keep in mind that journalistic communication must be useful and applicable in the world the audience lives in.  相似文献
