Ordering univariate distributions by entropy and variance   总被引:1,自引:0,他引:1  
This paper examines the role of variance and entropy in ordering distributions and random prospects. There is no universal relation between entropy and variance orderings of distributions. But we place their relationship in the context of a stronger ordering relation known as dispersion ordering. Further, some conditions are identified under which variance and entropy order similarly when continuous variables are transformed. We also analyze parametric changes which do not disturb the agreement between these rankings. The results are conveniently tabulated in terms of distribution parameters.  相似文献

This paper proposes a game theoretical approach of internationalnegotiations on transboundary pollution. This approach is distinguished bya discrete time formulation and by a suitable formulation of the localinformation assumption on cost and damage functions: at each stage of thenegotiation, the parties assign the best possible cooperative state, giventhe available information, as an objective for the next stage. It is shownthat the resulting sequences of states converges from a non-cooperativesituation to an international optimum in a finite number of stages.Furthermore, a financial transfer structure is also presented that makesthe desired sequence of states individually rational and stategically stable.The concepts are applied in a numerical simulation of the SO2transboundary pollution problem related to acid rain in Northern Europe.  相似文献

This study investigated several basic research questions suggesting a positive relationship between education and cognitive moral development. More specifically, these research questions examined the relationship between government mandated ethics education and cognitive moral development by testing the efficacy of a compulsory ethics intervention. Kohlberg's (1969, 1984) Cognitive Moral Development Theory was applied to test the efficacy of compulsory ethics education on the moral development of real estate salespeople used comparative statistical measures of ethical reasoning ability.The results of this research, while somewhat counterintuitive, suggest that the value of compulsory ethics education as an intervention to improve the moral reasoning of real estate salespeople is highly questionable. However, the results of the study do provide new insights into the relationship between ethics education and cognitive moral development.  相似文献

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”.  相似文献

Current development in social accounting presents an interesting phenomenon. Companies are increasingly engaging in sustainability initiatives and reporting their activities in annual reports, company websites and other media of communication. Unlike previous studies, which have mainly used ex post content analysis of annual reports or other published data to study the relationship between disclosure and possible determinants, this study starts with an interview with the local preparer before the data is triangulated to determine the significant possible determinants. The interview findings are interpreted through institutional theory for possible identification of determinants. Initially, the interview findings indicate that all three mechanisms of isomorphism, the coercive, the normative and the mimetic, contribute to Malaysian company sustainability reporting. However, the regression results prove that only a government linked company in the plantation industry, which is large in size, has a significant amount of sustainability reporting.

人作为生产活动的主体,往往根据自身需求是否得到满足来决定其工作态度,迫使许多企业和学者对激励进行研究,由此诞生了很多激励理论,其中需求层次理论以人的需求层次来划分人们的不同需求,双因素理论以保健因素和激励因素的划分来分析人们的需求,这两种理论之间相互联系,一个针对人的需要和动机,一个针对满足这些需要的目标和诱因,两者结合起来运用才能够更好、更有效地激励人们。  相似文献

The timing of exchange rate collapse   总被引:1,自引:0,他引:1  
Recent episodes of exchange rate collapse have renewed interest in models of speculative attacks. These episodes have been considered by some observers to be inconsistent with “fundamentals” models of attack since there was no prolonged period of policy misalignment and declining reserves, as required by such models. This paper develops a fundamentals model in which collapse is instantaneous at the time of unexpected policy change and/or a change in the expectations of future policy, even for a reserve abundant country.  相似文献
