内部人控制的形式、危害与解决措施

内部人控制问题引起了经济理论界和社会各界的广泛关注，经济学对其进行了较为深入的研究。但是，在对内部人控制的形式、产生的具体危害以及如何消除内部人控制的研究方面缺乏应有的深度。本文在分析内部人控制形式的基础上，探讨内部人控制对企业的影响，阐述了彻底解决具有垄断企业内部人控制的公开信息措施的原理。同时，也针对竞争性行业的内部人控制提出了内部人控制的一般解决措施。     

信息技术对竞争景框的影响--对波特观点的完善与修正

在分析信息技术对企业的影响时，波特教授对竞争景框变化的论述并不全面和完全正确。不全面在于，他只述及信息技术对地理景框和产业景框的影响，没有提到另两个方面——细分景框和纵向景框的变化。不正确在于，他笼统地提竞争景框的扩大或缩小，而竞争景框四方面在外力作用下变化并不总是一致的。本文认为，在信息技术影响下，竞争景框发生了四个方面不同的变化：细分景框、产业景框和纵向景框三个方面是缩小的，地理景框是扩大的。

工程造价市场信息分析及其在线系统开发

了解和熟悉某地区的市场信息对工程造价咨询公司在该地区开拓市场及造价工程师在该地区从事业务十分重要。本旨在探讨如何利用当代信息技术开发一个高性能的信息系统，它能为造价工程师提供及时的、全面和准确的市场信息(以上海地区为例)。系统开发所用的方法是一种改进的生命周期法。按照该方法，首先对工造价市场进行系统分析。然后，基于系统分析的结果，对市场信息进行分类，并在分类的基础上用超本技术建立信息模型。最后，基于模型开发信息系统。     

Informational Networks, Entrepreneurial Action and Performance

This paper develops a model that incorporates personal and business networks, firm action, and performance based on the existing literature. It explores the links between information and entrepreneurial-type action, and action and performance. Survey data was collected from a sample of 100 manufacturing firms in Thailand. Results show that entrepreneurs value the information they receive from their networks. However, there is little statistical support for tangible links between personal or business networks and entrepreneurial action and performance, or between action and performance.     

Characteristics of Earnings-Leading Versus Price-Leading Firms

This study attempts to identify firm characteristics that explain the disparity between the information content of accounting earnings and stock prices. Granger's causality concept was employed to classify sample firms into four groups: price-leading firms, feedback-system firms, earnings-leading firms, and no-causation firms. The feedback-system firms were either combined with the no-causation firms or eliminated entirely to form three sample groups. The entire sample firms then were divided into two classes. The first is for estimation, and the second is for prediction. Results indicate that firm size, capital structure, R-square of regressing prices at time t against earnings at time t – 1, R-square of regressing earnings at time t against prices at time t – 1, and percentage of shares held by institutions are the significant explaining variables. The application of the coefficient estimates to the hold-out sample indicates that 76.2% of the firms can be correctly classified into the corresponding groups. These results were consistent with those from canonical discrimination and other multivariate statistical methods.     

Models of Capital Investments with Private Information and Incentives: a Selective Review

The purpose of this paper is to selectively review research that addresses capital budgeting decisions in settings characterized by dispersed information and incentive problems. The papers are theoretical; they formulate and analyze models that vary in the number of periods considered, the number of economic actors involved, and the number of alternative projects available. The aims of the review are to describe some of the formulations that have been studied, to highlight their key economic and mathematical properties, to reveal their common economic forces, and to collect and organize their basic results.     

对金融衍生品市场内幕交易的一些新思考--澳大利亚现行的反内幕交易法及其带给我们的若干启示

本文着眼于澳大利亚在治理金融衍生品市场内幕交易中积累的丰富经验,针对一个崭新的前瞻性课题,即金融衍生品市场的内幕交易问题展开研究。作者认为,由于内幕交易与信息非对称性之间存在的内在冲突,实际上反内幕交易法规很难有效地阻止金融衍生品的内幕交易行为,过于复杂的反内幕交易法规会对市场产生一些负面影响,而放松内幕交易监管这一新思维将对市场的良性发展更为有益,应该让市场来决定内幕交易行为的“存亡”。但目前最为现实、温和的选择仍然是修改现行反内幕交易法,以维护市场的公平性和有效性。最后,笔者对如何缓解中国目前内幕交易猖獗的现状提出建议。     

交易透明度与信息揭示制度：国际趋势与启示

由于经济文化环境、交易制度、市场结构，技术模式和投资者分布等方面的差异，不同交易所在交易信息揭示的种类，数量和程度方面有所区别。本文首先总结了采取指令驱动的主要交易所的交易信息揭示制度和市场透明度，在比基础上分析了交易所交易信息揭示制度变革与市场透明度的发展趋势．希望能对我国证券市场交易信息揭示制度的发展提供一点有益的借鉴和启示。
