论企业物流成本管理

进入21世纪后,企业通过在生产领域降低成本获得竞争优势的空间已非常狭小,无疑,物流管理成为当前企业最重要的竞争领域。文中通过对企业物流成本现状进行分析,提出加强物流成本管理、降低流通费用、建立科学的物流成本核算体系的方法,从企业综合管理角度和物流方向各环节进行物流成本管理和控制,以获取市场竞争优势。     

The conservative equal costs rule, the serial cost sharing rule and the pivotal mechanism: asymptotic welfare loss comparisons for the case of an excludable public project

We examine the asymptotic behavior of two strategyproof mechanisms discussed by Moulin for public goods – the conservative equal costs rule (CER) and the serial cost sharing rule (SCSR) – and compare their performance to that of the pivotal mechanism (PM) from the Clarke–Groves family. Allowing the individuals’ valuations for an excludable public project to be random variables, we show under very general assumptions that expected welfare loss generated by the CER, as the size of the population increases, becomes arbitrarily large. However, all moments of the SCSR’s random welfare loss asymptotically converge to zero. The PM does better than the SCSR, with its welfare loss converging even more rapidly to zero.     

我国企业应用作业成本法面临的问题及对策

随着高科技在企业中的应用、市场竞争的加剧和顾客需求的多样化,作业成本法在我国企业应用的客观条件越来越成熟,对其展开的理论研究也必然有着广阔的空间和潜力。笔者从探讨应用作业成本法的实现途径与寻求解决作业成本法应用环境中存在问题的可行办法入手,以期对作业成本法在我国企业的应用有所帮助。     

基于价值链思想的作业成本法研究

首先,论述了基于价值链思想的成本管理方法如何弥补传统成本管理方法存在的诸多局限性;而后,对基于价值链思想成本管理的具体应用——作业成本法(ABC)进行研究,对其传统模型加以改进;同时,对存在的主要问题构建简单数学模型加以解决。     

On the cost-benefit of the regionalisation of the National Health Service

In this paper we analyse in formal terms the desirability of the regionalisation of a National Health Service. The policy consists of a devolution process, i.e. the increase in the health services provision to be decided by a region and financed by an increase in its revenues. The change is a marginal one, as it regards the part of supply of the health services exceeding a minimum standard, which for purposes of equity is maintained uniform in the national territory. As the central government is responsible for this component of the provision of health care (a federal “mandate”), the level of the said component is chosen by this authority and financed by federal taxation. Moreover, the government also applies an equalisation scheme based on the difference between a standard level of tax revenues and the revenues which the region is deemed able to raise for this purpose. Within the theoretical context of welfare improving reforms with distortionary taxation, we derive two conditions which focus on the regional, as well as the social, convenience of regionalisation.

The opportunity cost of duality

A dual representation of a technology, e.g., a cost function, may not contain all of the technological information, but it will contain all of the information about input vectors that would be chosen by a cost-minimizing firm. At least this much is clear for deterministic technologies. The main question addressed in this paper is whether the same can be said about stochastic technologies and their dual representations. Despite some pessimism expressed in the stochastic frontier literature on this question, we argue that there is no extra cost imposed in the stochastic case. Thus, the conclusion of this paper is: Just dual it!     

GAME THEORETIC MODELS OF MIXED OLIGOPOLY

Abstract. In this paper we review various models that have been proposed for the study of mixed oligopoly, that is markets in which private and public firm compete on equal basis using only market instruments.     

玻壳合格率及质量成本对策

本文从数理统计入手，给出了玻壳生产中更换产品前后合格率的关系公式，并和实际统计值进行了比较，有较好的符合，为科学量化分析提供了工具。并据此分析，不同尺寸的玻壳产品，当池炉系统的质量水平下降时，它们的合格率的差别也在扩大，并量可能会使得原先利润相对高的产品变得利润相对低。通过合理地计划产品品种的生产，可以获得更多的利润，降低单位成本。同时也阐明原有的新产品质量目标设定方法的不合理性，给出了质量目标设定的科学依据。
