基于消费者显著性偏好的双边平台转换成本和定价策略研究

针对消费者对转换成本和价格属性具有显著性偏好的实际情况，基于显著性理论对垄断双边平台企业的转换成本和定价策略问题进行了研究。研究发现：1)在显著性偏好非对称型市场上，对价格敏感的一方收取的价格最低，对高转换成本的一方收取的价格最高，而在显著性偏好对称型市场上，平台的最优价格位于非对称型市场之间，但是对价格敏感型市场收取的价格低于转换成本敏感型市场的价格。2)在高转换成本的市场，平台利润最低；低转换成本市场平台利润最高，而混合型情况的最优利润位于这两者之间。该研究结论说明平台企业应该采取措施来降低用户加入平台的转换成本，从而增加利润，这与现实的案例研究结论相吻合。     

幼儿园实际教育成本的模型构建与核算——以佛山某幼儿园为例

在界定幼儿园实际教育成本含义的基础上，确认其成本项目包含人员支出、公用支出、固定资产折旧和土地使用成本，以此为基础构建了幼儿园实际教育成本计量模型，并以佛山市某幼儿园为例核算出该幼儿园的实际教育成本。通过该园实际教育成本与标准教育成本的比较，发现该幼儿园教育经费投入不足且投入结构不合理，将来应重点增加人员投入。

A Comparative Analysis and Evaluation of a University Employee Assistance Program

Abstract

The major goal of this presentation is to provide overview of evaluation results of the University of Pittsburgh (Pitt) Faculty and Staff Assistance Program (FSAP). The major goal of the Pitt FSAP evaluation was to generate information pertaining to the program's service adequacy, program effectiveness, client satisfaction, cost-efficiency and cost-savings. Such an evaluation effort is becoming increasingly important due to the recent trend of organizational downsizing and coping with resource constraints. As Universities downsize, it can be challenging to justify allocating scarce funds to employee assistance programming. This study also includes review of EAPs among eighteen universities and colleges from around the country in order to compare program performance of the Pitt FSAP system.     

外商直接投资在中国经营方式变迁的新制度经济学分析

通过回顾外商直接投资在中国经营方式的变迁,认为经营方式的独资化趋势是一种自上而下以渐进式发生的强制性制度变迁,是在中国政府政策引导下的有微观主体自愿参与的制度变迁。运用新制度经济学的研究方法,通过对谈判结构和交易成本的分析,揭示了这一变迁的原因在于：合营企业和合作企业与外资企业在设立与运营过程中由于谈判结构的不同,而使后者在产权保护以及协议执行的成本更低,从而导致了外商直接投资在中国的独资化趋势。认为中国政府应出台政策提高利用外资的质量和水平,以降低＂独资化＂带来的负面影响。     

装卸搬运在物流管理环节中的作用研究

物流活动离不开装卸搬运,它贯穿于不同的物流阶段,因此装卸搬运是物流系统中重要的子系统之一。由于装卸搬运的伴生性和起讫性特点,导致它们经常被忽视,而只被看作是其他活动过程的一部分,没有像运输、储存等物流环节一样受到足够的重视。通过分析装卸搬运的特点,进而阐述装卸搬运在物流管理中的作用和意义。     

从国际视野看研究生教育成本分担

在西方国家,研究生交费入学,即生均教育成本分担被视为必然现象。如何联系我国研究生教育发展的实际,积极借鉴发达国家发展研究生教育的经验,把制订研究生教育成本分担与资助政策作为推进我国研究生教育运行机制改革的有效手段,已成为人们关注的焦点。建议在构建我国研究生教育投资主体多元化与资助政策的过程中,积极引进政策调节与市场竞争相结合的机制;实行研究生教育成本分担与资助的政策措施要与高校内部管理体制的改革有机结合起来。     

The Effects of Multitasking on Operations Scheduling

This study considers a typical scheduling environment that is influenced by the behavioral phenomenon of multitasking. Under multitasking, the processing of a selected job suffers from interruption by other jobs that are available but unfinished. This situation arises in a wide variety of applications; for example, administration, manufacturing, and process and project management. Several classical solution methods for scheduling problems no longer apply in the presence of multitasking. The solvability of any scheduling problem under multitasking is no easier than that of the corresponding classical problem. We develop optimal algorithms for some fundamental and practical single machine scheduling problems with multitasking. For other problems, we show that they are computationally intractable, even though in some cases the corresponding problem in classical scheduling is efficiently solvable. We also study the cost increase and value gained due to multitasking. This analysis informs companies about how much it would be worthwhile to invest in measures to reduce or encourage multitasking.     

Managing Logistics in Regional Banknote Supply Chain Under Security Concerns

We study the logistics problem faced by Regional Branches (RBs) of a central bank in managing the currency supply under security concerns. While making banknote supply decisions to Sub‐Branches (SBs), the management of RB must achieve two goals simultaneously: (i) guarantee that each SB has sufficient inventories of all denominations of banknotes to satisfy the demands from all commercial banks within its service area, and (ii) control the annual spending on this banknote supply operation. Due to security concerns, the following methods are implemented in the process of transporting banknotes: (i) the capacity of a cash truck is limited by the total face value (instead of the physical space) of banknotes, and (ii) empty decoy trucks are deployed along with the trucks filled with banknotes. After deriving a polynomial‐time strategy to guarantee an optimal solution for the special Bin‐Packing Problem faced in this study, we provide an exact formulation for the RB's supply planning problem. We also propose several polynomial‐time algorithms for deriving either optimal or near‐optimal solutions for the problem under different settings. Using the weekly demand data obtained from the central bank, we verify the performance of our algorithms, and analyze the impacts of changes in these features and in the fleet capacity on the total cost incurred by an RB under various scenarios.     

发电成本垂直差异电力市场概率发电——基于大用户电量偏好视角

针对碳减排后普遍存在的发电成本垂直差异电力市场及其显著的大用户电量偏好差异,本文提出概率性电量供给以及与之对应的概率发电,并利用价格杠杆调控发电商低碳发电尤其高发电成本发电机会与供给效能不足.先后构建发电成本内、外生选择下的概率发电模型,求解发电商的电量供给均衡并分析概率发电策略的最优性.最后,将发电成本内生选择模型拓展到分解市场需求不确定性的概率发电模型.研究发现:相比基准发电,概率发电可以作为一种有利可图的发电容量过剩的解决方法,即使在发电成本内生选择时也是可行的;当发电商采用“强”成本差异的发电策略时,引入折中的概率发电会让产品线上成本水平相互更接近,且大用户的消费者剩余得到提高;与此相反,在市场中实施“弱”成本差异发电,发电商利用概率发电则增大成本分离并降低大用户的消费者剩余;在不确定性市场需求下,当偏好低发电成本电量的大用户对单位发电成本的估价相对于偏好高发电成本电量的大用户对单位发电成本的估价足够高时,概率发电可以以一种管理不利需求状况工具的身份出现.
