Factor analysis for ranked data with application to a job selection attitude survey

Summary.  Factor analysis is a powerful tool to identify the common characteristics among a set of variables that are measured on a continuous scale. In the context of factor analysis for non-continuous-type data, most applications are restricted to item response data only. We extend the factor model to accommodate ranked data. The Monte Carlo expectation–maximization algorithm is used for parameter estimation at which the E-step is implemented via the Gibbs sampler. An analysis based on both complete and incomplete ranked data (e.g. rank the top q out of k items) is considered. Estimation of the factor scores is also discussed. The method proposed is applied to analyse a set of incomplete ranked data that were obtained from a survey that was carried out in GuangZhou, a major city in mainland China, to investigate the factors affecting people's attitude towards choosing jobs.     

论资本质量与财务目标

从传统财务目标的缺陷在于忽视资本质量的分析入手 ,论述了资本质量是资本的内在规定性 ,是资本社会属性的总和与资本经济属性的质量方面 ;将资本质量引入财务目标是由资本的本质和财务的本质、资本质量与资本数量之间的关系、时代特征和国家财务所决定的 ,资本质量最优化与资本数量最大化是财务目标的必然选择 ;提出了资本质量考核指标体系。     

ADDITIVE MODELS WITH PREDICTORS SUBJECT TO MEASUREMENT ERROR

This paper develops a likelihood‐based method for fitting additive models in the presence of measurement error. It formulates the additive model using the linear mixed model representation of penalized splines. In the presence of a structural measurement error model, the resulting likelihood involves intractable integrals, and a Monte Carlo expectation maximization strategy is developed for obtaining estimates. The method's performance is illustrated with a simulation study.     

生产函数与成本函数的关系研究

本文给出了生产函数与成本函数之间的一般关系,并证明齐次生产函数与齐次成本函数之间存在着一种齐次对应关系:齐次生产函数在厂商的成本最小化决策下必然产生齐次的成本函数且齐次成本函数必然产生对应于齐次的生产函数。     

行为目标偏离、规模扩大与利润率降低——对国有企业规模不经济的一种解释

我国国有企业经历过一个亏损的阶段,国有企业的规模与经济利润并不对称.国有企业的行为目标的偏离,使得国有企业的规模不断扩大,并最终出现规模不经济.必须实行"政企分开",培育有效的竞争机制,打破某些企业的垄断局面,让国有大中型企业逐步分解成依赖市场交易的多个主体,缩小企业规模.

Competition and Coordination in Two‐Tier Public Service Systems under Government Fiscal Policy

As a result of government budgetary limits and rapid market growth, many public service systems—such as health care—are characterized by extensive customer wait times that have become a serious problem. This problem might be solved by allowing private firms to enter these markets, which would provide customers with a choice between a free (governmental) public service provider (SP) and a fee‐charging (or “toll”) private SP. In such a two‐tier service system, the two SPs are differentiated by service quality and cost efficiency. This study focuses on the competition and coordination issues for two‐tier service systems with customers who are sensitive to both service quality and delay. The free system attempts to maximize its expected total customer utility with limited capacity, whereas the toll system attempts to maximize its profit. Neither goal is aligned with the social welfare goal of the public service. To achieve the social welfare goal, the government plays a crucial role in coordinating the two‐tier service system via the budget, the tradeoff of social members' goals, and tax‐subsidy policies. Using a mixed duopoly game, we establish Nash equilibrium strategies and identify the conditions for the existence of the two‐tier service system. We employ several interesting and counter‐intuitive managerial insights generated by the model to show that the public service can be delivered more efficiently via customer choice and SP competition. In addition, we show that a relatively low tax‐subsidy rate can almost perfectly coordinate the two SPs to achieve most of the maximum possible benefit of the two‐tier service system.     

网络群体事件政府治理的演化博弈分析

利用演化博弈模型预测舆论的发展趋势,对政府应对网络群体事件采取的治理模式进行了研究.在一般化复制动态模型基础上建立网络群体事件舆论的传播方程,将地方政府部门与弱势群体的策略互动和行为演化融入到传染病传播模型中,用以模拟舆论的扩散和收敛过程.结果表明:在网络群体事件初期,如果弱势群体通过抗争获得政府补偿的概率不断增大,将造成事态的扩大.此时,地方政府应控制信息的交流程度与初始抗争人数,减缓舆论的扩散;在网络群体事件舆论大范围扩散阶段,上级政府介入并采取惩罚措施,及时披露信息,促使网络舆论的收敛平息,实现社会福利最大化.     

利益相关者管理——新经济下的机会与挑战

"股东至上主义"是盎格努--萨克逊体系公司治理模式的核心,但是它却忽视了相关者的利益要求,从而给企业带来了一系列的管理悖论.而在知识化、信息化为主要特征的新经济条件下,利益相关者的参与同合作情况对企业的经营成败有着至关重要的影响作用.于是,利益相关者管理逐渐受到了理论与实践上的重视.虽然通过利益相关者管理可以实现企业长期价值的提高,促进企业可持续发展等,但在实际操作过程中还存在许多需要进一步明确的问题.     

文化与效用极大化的方向——20世纪30年代一个内地村庄的生活方式及其经济学意义

人类效用极大化的方向至少有两个:一个方向是欲望满足的最大化,对应于西方文化里的生活态度与人生目标;另一个方向是身心痛苦的最小化,对应于中国传统文化里的生活态度与人生目标.在费孝通早年研究的云南禄村,小地主们过着一种整天闲混的生活,他们依靠雇工种田,自己尽可能不工作.这是一条追求身心痛苦最小化的人生道路,与资本主义精神格格不入.因此,解释人类行为及社会现象的经济学理论,需要与当事人的生活态度及文化传统相契合,故具有本土特征.
