The Morishima gross elasticity of substitution

We show that the Hotelling–Lau elasticity of substitution, an extension of the Allen–Uzawa elasticity to allow for optimal output-quantity (or utility) responses to changes in factor prices, inherits all of the failings of the Allen–Uzawa elasticity identified by Blackorby and Russell [(1989) Am Econ Rev 79: 882–888]. An analogous extension of the Morishima elasticity of substitution to allow for output quantity changes preserves the salient properties of the original Hicksian notion of elasticity of substitution. We thank Paolo Bertoletti for drawing our attention to the issue addressed in this paper and for his comments on an earlier draft.

基于模糊聚类的客户分类应用研究

为解决客户关系管理中的客户分类问题，引入了模糊聚类分析算法。通过分析客户购买力的单因素数据矩阵，以客户胸买力之间相似程度作为聚类指标，应用模糊聚类分析法，求得客户的相对隶属度，从而为客户类别的划分提供科学分类依据。在特征函数确定问题上，提出了结合2/8营销理论的一种新方法。     

Public goods provision: Unit-by-unit cost-sharing rules and the core

In a simple model of one public good producible from one input, we show that unit-by-unit cost-sharing rules have two properties. First, a unit-by-unit cost-sharing rulealways chooses a core allocation. Second, every allocation in the core will be chosen by at least one unit-by-unit cost-shring rule. We argue that costs should be shared on a unit-by-unit basis. We propose a simple mechanism to implement the family of unit-by-unit rules.

Ownership structure and post-issue operating performance of firms conducting seasoned equity offerings in Thailand

This paper investigates the post-issue operating performance of companies that conducted seasoned equity offerings (SEO) in the Stock Exchange of Thailand (SET) during the period 1991 to 1994. It is documented that SEO firms exhibited declining operating performance after the offering. Further, there is a negative relation between inside ownership concentration and postissue operating performance decline. In support of the signaling effect, the ratio of issue proceeds to pre-issue equity also negatively relates to post-issue operating performance. Further, the negative relation between issue proceeds and operating performance decline is intensified among SEO firms with high insider ownership concentration. The finding offers evidence in support of agency conflicts and information asymmetry and suggests that the two factors are operating simultaneously.     

对ESOP激励有效性的质疑

本文提出在ESOP实施过程中存在着员工持股股份占企业总股份的比例较低;员工个人持股比例很低的现状,并针对这种现状,质疑“有效员工激励”是否能够实现。本文将结合模型,主要从ESOP是否能增加员工有形动力和是否能增加员工无形动力两个方面来具体阐述自己的观点。
