对供应链中"牛鞭效应"综合治理策略的探讨

通过文献综述,讨论了供应链中牛鞭效应的现象和成因，提出了减轻和消除该效应的对策以及进一步研究方向。     

信用交易保证金与股价波动关系研究

通过对境外市场保证金变动对股价波动影响的实证结果进行梳理后发现,保证金的调整对市场波动产生两种相反的效果,即流动性效果和投机性效果,保证金对市场波动的影响取决于两种效果的力量对比,如果流动性效果较强,则调整保证金对股价波动无影响或加剧市场波动,反之,则会减轻市场波动。     

供应链中的牛鞭效应及其研究

文章通过供应链管理中出现的实际问题,引出了牛鞭效应的概念,阐述了研究牛鞭的重大意义,总结了国内外专家学者对牛鞭效应的研究动态,分析了多级、每级有多个成员的供应链结构的牛鞭效应,并在其基础上进行发展。旨在寻求一种方便可行、从牛鞭的源头动力出发的预警指标,并针对过程中的模型分析重整影响牛鞭效应的要素。     

Do liquidity induced changes in aggregate dividends signal aggregate future earnings growth?

Extant empirical literature does not provide abundant evidence for the information content hypothesis regarding firm-level dividend signaling. Although this is consistent with the argument against an optimal firm-level dividend policy, this does not imply an absence of an optimal aggregate dividend level. Aggregate dividends and earnings may exhibit stronger associations if aggregation filters out firm-specific earnings information and indicates macroeconomic trends. Using macroeconomic data, we show that aggregate payout ratios signal aggregate future earnings growth for horizons up to 4 years, and that excess aggregate liquidity plays an important role in this relationship.

Small-sample Properties of Panel Spatial Autoregressive Models: Comparison of the Bayesian and Maximum Likelihood Methods

Abstract

This article considers autoregressive (SAR) models. We method to estimate the parameters of likelihood (ML) method. Our Bayesian by the Monte Carlo studies. We found the efficient as the ML estimators.     

Pyrrhic victories – anticipating the closedown effect

Previous studies with empirical evidence on social responsible driven closedowns have identified a productivity increase effect that occurs during the process of organizational closedowns, known as the closedown effect. Our proposition is that this effect can be anticipated as a consequence of a closedown decision. Encountering four different non social responsible closedown cases, of various durations, we statistically test this proposition. Further, we identify a need for an analytical distinction of the phases of the closedown process, in terms of the primary ‘advanced notice period’ and the secondary ‘countdown period’. Based on the analysis, and with this distinction, we are able to conclude that the productivity increase effect can be anticipated during the countdown period. The comparably longer time frame in the Studding case provides the strongest support for our proposition. From the analysis we suggest hypotheses for further research.     

基于多Agent的供应链牛鞭效应建模与仿真

文章基于多Agent技术构建了啤酒游戏供应链的仿真模型,给出了基于多Agent技术和Swarm平台构建供应链仿真模型的方法。基于该模型对供应链牛鞭效应进行了仿真分析,进一步深化了对牛鞭效应的认识。     

区域经济发展下物流园区的物流资源聚集效应研究

指出物流园区的物流资源聚集效应与区域经济发展密切相关,前者是后者的发展需求,后者是前者发展的基础。物流园区资源聚集效应形成和扩展受到园区规划、园区运作管理、区域经济发展、区域政府的推动等多种因素影响,区域经济发展下可以从相关因素着手针对性地推动聚集效应的正向发展,从而使资源聚集效应更好更多地为区域经济发展服务。     

消费对经济增长的拉动作用研究——基于城乡消费结构的比较

消费是一个国家经济增长的源动力,是公民福利增加的源泉,如何发挥消费对经济的拉动作用已成为学术界研究的热点问题。基于城乡消费结构比较的视角,就消费对经济的拉动作用以及我国城乡居民消费结构的差异进行了研究,结果显示：消费对经济增长具有积极的拉动作用;居民收入水平较低、收入水平差距较大是我国城乡居民消费对经济增长拉动作用较小的重要原因;我国城乡居民的消费结构存在差别,主要原因在于城乡收入水平的差别,持续强劲的居民消费需要以居民的收入持续增加为基础。为此,应从提高居民收入水平、减小城乡居民收入差距、建立完善的医疗保障体系、合理的消费引导等方面来改善城乡居民的消费结构,以真正发挥消费对经济增长的促进作用。     

个人住房贷款政策对房地产市场的影响研究

金融政策的调整对房地产业发展具有重要影响,这一点在许多国家已经得到证实,在中国也逐步成为政府调节房地产业发展的手段。近年来,个人住房贷款政策随着房地产调控政策的出台而随之变化,本文研究中国个人住房贷款政策调整在对房地产市场的影响,并对如何促进房地产行业的发展,做出相关建议。
