上海股市周日历效应及长期记忆研究

运用ARMA-GARCH-M、EGARCH-M及FIGARCH-M模型对上海股市A股指数收益率及其波动性的周日历效应进行联合检验;另外还检验了成交量的周日历效应。研究结果表明:(1)风险溢价系数为正值,上海股市的风险传递机制正在发挥作用;(2)股市收益率序列存在显著的周日历效应,并且其异常收益并非来自风险溢价;(3)波动性过程同时存在周日历效应和长期记忆效应;(4)股市交易量同时存在周日历效应和长期记忆效应。最后利用混合分布假说进行了解释,信息可能是周日历效应形成的重要原因。     

战略阻绝效应对战略联盟决策的影响分析

本文将对战略联盟决策的分析纳入SCP范式,并通过构造在位者和潜在进入者之间的三阶段博弈模型来分析战略阻绝效应对战略联盟决策的影响.本文认为:在位者的合适的战略联盟行为具有战略阻绝效应,可以通过改变潜在进入者的进入预期、影响进入者的行为并促进在位者的支付,这种支付的改变将拓宽战略联盟的决策空间,在位者将在更高的联盟成本或更低的固定边际成本下降程度上建立战略联盟.

Attracting Micro‐Enterprises To Learning

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’.

A simple estimator for a shared frailty regression model

Summary. We propose a simple estimation procedure for a proportional hazards frailty regression model for clustered survival data in which the dependence is generated by a positive stable distribution. Inferences for the frailty parameter can be obtained by using output from Cox regression analyses. The computational burden is substantially less than that of the other approaches to estimation. The large sample behaviour of the estimator is studied and simulations show that the approximations are appropriate for use with realistic sample sizes. The methods are motivated by studies of familial associations in the natural history of diseases. Their practical utility is illustrated with sib pair data from Beaver Dam, Wisconsin.

太平天国乡官的任用标准与社会功效

对太平天国乡官制度的研究,传统的阶级分析论观点过分拘泥在乡官的阶级成分上,并以此为基础判定政权的性质。其实,以历史当事人的视角去认识当时的政策,是一种更客观的研究角度。太平天国任用乡官的标准,是建立在太平天国地方行政的政治需要之上的。出于以征收粮赋为重点的传统地方行政的需要,太平天国着意与精通传统行政事务的地方名流合作。从社会功效角度来看,太平天国当局通过发挥地方人士的行政优势,很好地弥补了自身行政经验的不足,成功影响了地方政治,并有效缓冲了自身对农村社会的冲击。
