企业资源标识的方法研究

在企业运作过程中,企业会使用各种资源。资源标识是一种高效明示该资源特征属性的信息形式,但目前国内外还没有文献对企业资源标识这种简述形式进行一般性地理论定义和描述的相关研究。本文通过建立企业资源标识的概念模型、集合结构模型及拼图结构模型,从理论上一般性地定义和描述企业资源标识,并归纳出13条标识的基本原则,为分析、设计和管理企业资源标识奠定一定的理论基础,这是企业微观管理研究的一个原创性探索。     

On the efficiency of the negligence rule

The three versions of the negligence rule discussed in the literature differ regarding whether a negligent injurer is liable for the entire loss or only for the incremental loss; or regarding whether negligence is defined as failure to take at least due care or failure to take a cost‐justified precaution. It is shown in the paper that the incremental version with untaken precaution notion of negligence is not efficient; not even for the unilateral case. The paper also establishes, for the bilateral case, the efficiency of the incremental version with the shortfall‐from‐due‐care way of defining negligence.     

Development of a national competitiveness index based on a structural equation model

In this paper, we propose a national competitiveness index using raw Institute of Management Development (IMD) data and try to overcome a shortcoming in the IMD's own ranking system. The IMD world competitiveness ranking considers 20 factors to define an index, but it does not consider the structural relationships among various factors. We utilise a structural equation model to derive a national competitiveness index that reflects such structural relationships. We then reveal new rankings of world competitiveness. In addition, we conducted a comparison analysis by economy level and identified improvement points in terms of measurement variables as well as latent variables. Our work is expected to promote a new era of national competitiveness rankings and indices.     

Efficiency of health care delivery systems: effects of health insurance coverage

Health insurance expansions may increase the demand for care-creating incentives for health systems to increase input consumption. The possibility remains that added capacity and personnel will have little effect on health outcomes, decreasing the technical efficiency of health care delivery systems. We estimate that a 1 percentage point increase in health insurance coverage decreases the technical efficiency of health care delivery by 1.3 percentage points, translating into approximately 50 billion dollars in additional health expenditures. This finding uncovers a previously unexplored consequence of changes in health insurance on the supply side of health care markets suggesting one avenue through which health care costs growth may occur.     

Competition for foreign direct investment: The role of technology and market structure

We analyze the location choice of a multinational corporation (MNC) between two host countries. We consider both passive and active governments and examine the role of production efficiencies, and of market structure, in the MNC's choice. Our findings include: (i) when the domestic firms export, the country with fewer firms always gets the MNC, but the MNC is indifferent between hosts with firms that have different efficiency levels, (ii) when the domestic firms do not export, the country with more firms gets the MNC if they are sufficiently inefficient, and the MNC locates in the country with less efficient firms.     

20世纪90年代以来中国经济的动态效率

本文借助于西方宏观经济学中的索洛经济增长模型和拉姆齐 卡斯 库普曼斯模型 ,讨论了宏观经济中最优消费和储蓄的确定机制 ,并得出判断宏观经济运行动态效率的黄金定律以及修正黄金定律标准。同时 ,借助代际交叠模型从理论上探讨了自由竞争经济出现动态无效的可能性。在此基础上 ,我们利用黄金定律规则对中国实际经济运行的动态效率进行了考察 ,认为 2 0世纪 90年代初起中国经济运行处于一种动态无效状态 ,进而我们深入分析了造成中国经济出现动态无效的原因。根据中国经济处于动态无效的事实 ,并结合原因探索 ,我们最后提出了摆脱动态无效困境的若干政策建议。     

企业边界:基于动态效率的分析

企业边界是企业理论关注的一个焦点,不同的理论分支对之有不一样的见解.本文在批判了新制度经济学中用边际交易成本解释企业边界论的基础上,从企业的知识、能力出发,按照动态效率标准对企业边界提出了自己的看法,即企业依据自身情况制定的发展战略是影响企业边界的重要因素.
