Modelling soccer matches using bivariate discrete distributions with general dependence structure 总被引:1,自引:0,他引:1
In this paper copulas are used to generate bivariate discrete distributions. These distributions are fitted to soccer data from the English Premier League. An interesting aspect of these data is that the primary variable of interest, the discrete pair shots-for and shots-against, exhibits negative dependence; thus, in particular, we apply bivariate Poisson-related distributions that allow such dependence. The paper focuses on Archimedian copulas, for which the dependence structure is fully determined by a one-dimensional projection that is invariant under marginal transformations. Diagnostic plots for copula fit based on this projection are adapted to deal with discrete variables. Covariates relating to within-match contributions such as numbers of passes and tackles are introduced to explain variability in shot outcomes. The results of this analysis would appear to support the notion that playing the 'beautiful game' is an effective strategy—more passes and crosses contribute to more effective play and more shots on the goal. 相似文献

按劳分配与收入公平分配 总被引:1,自引:0,他引:1
白书祥 《湖北经济学院学报》2006,4(6):31-36
按劳分配与收入公平分配存在正相关,主要表现在按劳分配存在前提和分配主体转换的公平性、分配依据和利益结构及其主体地位的合理性五个方面.按劳分配的实践与收入公平分配存在负相关,主要表现在由于理解上的偏差、应用中的偏差、实施对象客观条件不同而导致收入分配中事实上的不公平.为了强化按劳分配与收入公平分配的正相关、弱化按劳分配的实践与收入公平分配的负相关,必须采取相应对策. 相似文献

翻译学是一门综合社会科学,包括文学翻译,句法翻译,科技翻译,同声翻译和电脑翻译等学科,其采用的方法的手段又是多样的,诸如:直译、意译、扩译、省译、词类转换和正反译等等,但所遵循的原则是译者用一种语言表达原作者用另一种语言所表达的同一概念或思想。该文力图通过具体的实例浅析正反译法在翻译实践中的相互应用。 相似文献

资产减值等有关问题是目前我国会计理论和实务中急需加以关注的问题之一,本文试图通过对我国有关资产减值准则制度与英国会计准则委员会(ASB)发布的财务报告准则第11号(FRS11)比较,以期从中借鉴有益部分,促进我国有关资产减值会计的完善。 相似文献

税收公平原则富含社会伦理的思想。对个人所得税的征管,不仅要强调其经济功能,更要关注其社会公正和伦理维护的社会功能。我国的个人所得税制存在纳税人身份确定、纳税能力确定、征税范围确定三个方面的公平伦理扭曲。因此,新的个人所得税构想中应当强调全民纳税、量能负担原则,实行低累进税率和负所得税税率,同时要改进征管模式。 相似文献

This study investigates the effect of flexible tax enforcement on firms’ excess goodwill using unique manually collected data on taxpaying credit rating in China from 2014 to 2021. We document that A-rated taxpayer firms have less excess goodwill; A-rated firms reduce excess goodwill by 0.005 vis-a-vis non-A-rated firms, which accounts for 100% of the mean value of excess goodwill. This finding holds after multiple robustness tests and an endogeneity analysis. Moreover, this negative effect is more pronounced in firms with low information transparency, that are non-state-owned and that are located in regions with low tax enforcement intensity. The channel test results suggest that taxpaying credit rating system as flexible tax enforcement reduces firms’ excess goodwill through a reputation-based effect and not a governance-based effect. This study reveals that the taxpaying credit rating system in China as flexible tax enforcement can bring halo effect to A rating firms, thereby limiting irrational M&As and breaking goodwill bubble. 相似文献

关于商誉会计理论的思考 总被引:5,自引:0,他引:5
商誉是会计界所关注的一个焦点问题,历来倍受争议。本文从对商誉本有关质诸多观点的分析出发, 得出商誉的再定义。同时,针对理论界与实务界区别对待自创商誉与外购商誉的现状,也分析论证了两者的内在统一性,提出当前更应重视自创商誉问题研究的建议,并对自创商誉的计量及后续处理问题予以探讨,以期有助于商誉会计的整体协调发展并最终达成科学的共识。 相似文献

Summary. We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous
and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem
stated in terms of prices and commodities into a finite-dimensional Negishi problem involving individual weights in a social
value function. This method allows us to obtain detailed results concerning the properties of competitive equilibria. Because
of the simplicity of the techniques utilized our approach is amenable to be adapted by practitioners in analogous problems
often studied in macroeconomics.
