股权结构的适度性与公司治理效率

股权结构与公司治理效率存在着密切的关系,在一定条件下,股权结构决定着公司治理结构,适度的股权结构又是影响公司治理效率的决定因素之一。本文从股权结构的适度性角度来考察德美日公司的治理效率,并在此基础上提出了建立有效的公司治理的股权结构适度性模型,从而对转轨时期的中国企业公司治理改革具有一定的参考价值。     

产业共性技术产学研协同研发策略的微分博弈研究

针对产业共性技术产学研协同研发问题,本文以单个研究机构（大学、科研院所）和单个企业为研究对象,通过构建微分博弈模型,运用HJB方程分别分析了三种产业共性技术研发博弈情形下研究机构和企业各自的最优研发努力程度、最优研发收益、双方最优研发总收益以及企业对研究机构的研发投入补贴。通过对三种博弈结果的比较分析发现：（1）研发投入补贴作为一种激励策略,可促进研究机构研发努力程度、研究机构与企业各自研发收益以及双方研发总收益的提升;（2）协同合作博弈情形下研究机构与企业各自研发努力程度、各自研发收益和双方研发总收益均优于非合作情形。为协调研究机构与企业的产业共性技术协同研发行为,通过讨论收益分配系数α的取值范围进而分析产业共性技术产学研协同研发的收益协调机制。最后,通过算例分析验证了理论推导的结果。

Ex Ante and Ex Post Values for Changes in Risks

In this paper, I take risk to mean a composite of the probability of an adverse event and the severity of the consequences of the event. I explore two issues in the economic valuation of changes in individual risks brought about by public policies. These are: (1) the relationship between the values of risk prevention (i.e., the lowering of the probabilities of adverse events) and risk reduction (i.e., the reduction of the severity of the consequences of adverse events); and (2) the relationship between ex ante and ex post measures of the value of changes in risk.     

日本企业的董事会改革

董事会是股份公司治理结构的核心部分。本文通过对日本企业董事会现状的分析,揭示出相对于欧美企业,日本的董事会具有人数多、内部董事比例高且同质化、决策职能、执行职能和监督职能没有分开等特点,其结果是董事会在公司治理中事实上已蜕变成仅是应商法要求而存在的机构。为改变这种状况,日本现正从修改商法入手对董事会进行变革。     

Uncertainty and Variability Analysis in Multiplicative Risk Models

Currently, there is a trend away from the use of single (often conservative) estimates of risk to summarize the results of risk analyses in favor of stochastic methods which provide a more complete characterization of risk. The use of such stochastic methods leads to a distribution of possible values of risk, taking into account both uncertainty and variability in all of the factors affecting risk. In this article, we propose a general framework for the analysis of uncertainty and variability for use in the commonly encountered case of multiplicative risk models, in which risk may be expressed as a product of two or more risk factors. Our analytical methods facilitate the evaluation of overall uncertainty and variability in risk assessment, as well as the contributions of individual risk factors to both uncertainty and variability which is cumbersome using Monte Carlo methods. The use of these methods is illustrated in the analysis of potential cancer risks due to the ingestion of radon in drinking water.     

Technological newness: An empirical study in the process industries

Technological change in product development is a crucial issue in the management of technology. The entire sweep of technological changes over the past hundred of years is, in essence, the sum of thousands of individual product development projects in thousands of firms. Yet the degree of technological change in individual development projects has not been extensively studied. This paper presents a four-dimensional characterization of technological newness for product development projects in the process industries in which product development is closely tied to process innovation. The characterization uses four dimensions of change that are required in the development of new products: chemistry, production equipment, fabrication technology and process control. Based on the framework of technological newness, the paper presents data collected on the degree of process change in a set of 20 product development projects conducted by a large manufacturer of advanced polymers. The data provide a clear demonstration of the value of the measurement framework, showing a strong relationship between the characterization of change and the project performance.     

基于政府隐性担保退出预期的金融机构违约风险重定价

取消政府隐性担保或将成为未来政策重点,这将引起隐性担保退出的市场预期,导致金融机构违约风险的重定价。在金融机构自身资产价值随机运动的情形下,文章分别分析了离散时间隐性担保与连续时间隐性担保下金融机构总资产价值的动态随机运动规律,在结构化模型框架内构建了考虑政府隐性担保预期的违约风险模型,度量了政府隐性担保退出过程中不同风险状态金融机构的违约概率与预期损失。研究表明：（1）随着政府隐性担保逐步退出,金融机构违约概率逐渐增加,预期损失呈现先增加后递减的过程。（2）金融机构资产价值波动率越大,杠杆率越高,在政府隐性担保退出过程中其违约概率与预期损失越大。     

The impact of R&D sources on new product development: Sources of funds and the diversity versus control of knowledge debate

We build on the knowledge-based view to study the relative impact of alternative R&D sources on innovation performance. We contrast two arguments that have created a debate in the literature: One is that diversity of knowledge is better for innovation, because the integration of a larger variety of knowledge helps create new products that can fulfill unmet customer needs; another is that control of knowledge is better, because the incentives and contextual system of the firm facilitate employees' experimentation, which supports the creation of new products. We provide one solution to this debate by arguing that the relative importance of diversity and control of knowledge on innovation depends on the sources of finance. Hence, we find that, in general, control of knowledge has a higher impact than diversity of knowledge on the sale of new products. We also find that alternative sources of finance moderate the relationships: internal funds strengthen the impact of R&D sources with more diversity of knowledge on the sale of new products, while external funds strengthen the impact of R&D sources with more control of knowledge on the sale of new products.     

协商式转移定价与成本转移

企业制定转移定价的目的之一是对管理者的业绩进行评价,而转移定价采用协商方式进行,其目的则在于制定一个转移双方都满意的转移价格,从而有利于企业经营业绩的提高。那么,协商方式是否会影响转移定价的业绩评价功能呢?本文运用实验研究方法就此展开研究。研究结果表明,当卖方成本上升时,协商式转移定价也会随之上升,它表明协商式转移定价导致了成本转移,从而对转移定价的业绩评价功能产生负面影响。本文首次研究了协商式转移定价对转移定价业绩评价功能的负面影响,为实施协商式转移定价的企业提出需要关注的重要问题。     

Negative Effekte von Coaching und ihre Ursachen aus der Perspektive der Organisation

Negative effects of business-coaching and their causes have been barely addressed in research so far. In this qualitative pilot-study the perspective of organisations is being addressed for the first time. The most frequently stated negative effects were a too strong development of clients in the perception of the interviewees, a termination of the job by clients, a lack of sustainability of the results and an insufficient return on investment. As influencing factors e.?g. the attitude of the organisation towards coaching, imprecise clarification of coaching assignments, lack of motivation of the client or the working methods of coaches were reported.     

Selection of Probability Distributions in Characterizing Risk of Extreme Events

Use of probability distributions by regulatory agencies often focuses on the extreme events and scenarios that correspond to the tail of probability distributions. This paper makes the case that assessment of the tail of the distribution can and often should be performed separately from assessment of the central values. Factors to consider when developing distributions that account for tail behavior include (a) the availability of data, (b) characteristics of the tail of the distribution, and (c) the value of additional information in assessment. The integration of these elements will improve the modeling of extreme events by the tail of distributions, thereby providing policy makers with critical information on the risk of extreme events. Two examples provide insight into the theme of the paper. The first demonstrates the need for a parallel analysis that separates the extreme events from the central values. The second shows a link between the selection of the tail distribution and a decision criterion. In addition, the phenomenon of breaking records in time-series data gives insight to the information that characterizes extreme values. One methodology for treating risk of extreme events explicitly adopts the conditional expected value as a measure of risk. Theoretical results concerning this measure are given to clarify some of the concepts of the risk of extreme events.     

Dimensions of Control in UK International Joint Ventures*

From a sample of UK joint ventures with partners from Western Europe, the USA and Japan, dimensions of parent control of the ventures are considered by way of a taxonomy based on the mechanisms, extent and focus of control. The origins of the mechanisms of control identified in the study indicate that UK parents have not been sufficiently responsible for providing the mechanisms to allow them to exercise a greater leverage of control than that obtained by the foreign partners. The origins of the mechanisms of control also indicate relatively little autonomy for the managements of the joint ventures. Evidence from the study supports the view that joint venture parents seek to focus their influence of control over particular decisions and activities of the venture, rather than attempting to extend their control over the whole venture. The study considers the mechanisms and focus of control across the characteristics of the sample: contractual form of the venture, relative equity shareholding of the UK parent, time period of formation, nationality of foreign partner, industry group of the venture and broad purpose of the venture. Chi-squared tests show that there is little evidence of any systematic variation in the dimensions of control across the characteristics of the sample, the major exception to this being the relative equity shareholding of the UK parents.     

Rising prices,financial statements and fundamental research

Adequate consideration cannot be given to the subject of inflation accounting without a rigorous reappraisal of the nature and usefulness of published financial statements. It is argued that much fundamental research is a necessary prerequisite for the evaluation of methods of accounting in a period of inflation. Such research should begin with a consideration of the purposes to be served by the publication of financial statements. A framework is presented for such fundamental research and the results of some preliminary work outlined to assess the usefulness of financial statements in providing information to assist investors to make investment decisions. The use of financial statements by investors for this purpose is one of a number of possible objectives for financial statements.

考虑公平偏好的双重信息不对称下PPP项目激励机制研究

PPP项目中社会资本的能力禀赋和努力水平为其私有信息,如何激励社会资本显示真实的能力禀赋和努力水平一直是PPP项目治理研究的重要议题。在传统的PPP项目激励治理研究中,往往假设社会资本只具有单一私有信息,由此形成单一的逆向选择或道德风险问题。但在PPP激励治理现实中,社会资本经常同时拥有关于能力禀赋和努力水平双重私有信息,从而导致关于类型不对称信息的逆向选择和关于行为不对称信息的道德风险问题共存。本文研究了PPP项目中逆向选择和道德风险共存的激励机制设计问题。构建了针对社会资本同时拥有能力禀赋和努力水平两种私有信息的激励机制设计模型。该模型以项目产出绩效为激励途径,通过设计最优契约使得社会资本谎报信息类型的收益水平不高于其真实汇报类型的收益,从而激励社会资本显示真实能力禀赋的同时付出最优努力水平,保证项目效率。同时考虑了社会资本的公平偏好,探讨了公平偏好对这种双重不对称信息激励机制设计的影响。研究表明：通过设计合理的PPP项目激励机制能够实现对社会资本的信息甄别和激励其付出最优努力的双重目的,政府对社会资本的激励强度同社会资本市场分布有关,且随着社会资本嫉妒偏好强度的提高和被指责偏好强度的减弱而增大。本文的研究可以为解决现实中PPP项目的激励机制设计问题提供理论依据和决策参考。     

Price Setting With Menu Cost for Multiproduct Firms

We model the decisions of a multiproduct firm that faces a fixed “menu” cost: once it is paid, the firm can adjust the price of all its products. We characterize analytically the steady state firm's decisions in terms of the structural parameters: the variability of the flexible prices, the curvature of the profit function, the size of the menu cost, and the number of products sold. We provide expressions for the steady state frequency of adjustment, the hazard rate of price adjustments, and the size distribution of price changes, all in terms of the structural parameters. We study analytically the impulse response of aggregate prices and output to a monetary shock. The size of the output response and its duration both increase with the number of products; they more than double as the number of products goes from 1 to 10, quickly converging to the response of Taylor's staggered price model.
