Software for Learning and for Doing Statistics

The community of statisticians and statistics educators should take responsibility for the evaluation and improvement of software quality from the perspective of education. The paper will develop a perspective, an ideal system of requirements to critically evaluate existing software and to produce future software more adequate both for learning and doing statistics in introductory courses. Different kinds of tools and microworlds are needed. After discussing general requirements for such programs, a prototypical ideal software system will be presented in detail. It will be illustrated how such a system could be used to construct learning environments and to support elementary data analysis with exploratory working style.     

Investment Opportunities and the Relation Between Equity Value and Employees' Bonus

A sample of firms where employee stock options and other long‐term incentives are absent but an annual bonus is required is examined. A positive relation is found between firm equity value and stock bonus but not cash bonus. The positive relation is stronger when the firm has greater investment opportunities. Additionally, the relation is shown to be nonlinear in the sense that the marginal effect of stock bonus on equity value is positive but decreasing (negative) when the stock bonus is below (above) the breakpoint. Overall, the annual stock bonus is valued positively by investors even though it is linked to the firm's contemporaneous but not future performance.     

On Sraffa's Standard commodity: is its price invariant with respect to changes in income distribution?

In his 1960 book, Sraffa suggested using a composite commodity,which he called the ‘Standard commodity’, to solveRicardo's search for an invariable measure of value, i.e., astandard capable of isolating the price movements of any othercommodity induced by changes in income distribution. The absencein Sraffa's book of an explicit proof of the invariance propertyof this standard gave rise to many misunderstandings about itsmeaning and its role as an invariable measure of value. In orderto clear up these questions, Bellino (On Sraffa's Standard commodity,Cambridge Journal of Economics, vol. 28, 121–32, 2004)has proposed a ‘proper’ definition of an ‘invariablemeasure of value’, showing that Sraffa's Standard commoditydoes fulfil the requirements of this definition. He claims thatthe fulfilment of this property (but not the constancy of its‘nominal’ price) qualifies the Standard commodityas an invariable measure of value. In this paper, a proof ofthe invariance of the price of the Standard commodity with respectto changes in income distribution is given, and the equivalenceof this property with Bellino's definition of invariance isshown.     

公司财务控制机理:一个基于制度博弈的分析

财务控制的目标是对出资者和经营者之间形成的代理契约的冲突进行管理和协调.以出资者与经营者的制度博弈模型为分析基础,可以清楚表明财务控制机理特征:首先,财务控制本身具有的制度成本(控制成本)是制约控制成效的关键因素;其次,财务控制作为一种制度安排,应具备使经营者违背代理契约的外部成本内部化的功能;最后,财务控制本质是一种契约安排,是出资者和经营者之间多次动态博弈的结果,因此需要不断进行修正完善.     

基于“行为经济学理论”的旅游者行为分析

传统的旅游者行为分析方法,主要是进行定性的分析,将各个因素进行框架分析,而对旅游者行为的影响因素分析深度不够。借助行为经济学的理论和分析方法,从旅游者的心理活动角度入手,注重旅游者的心理变量分析,应用前景理论和心理账户分析旅游者行为,充分考虑了情境因素和体验因素,使得关于旅游者的行为分析更加细化和接近现实生活。     

基于博弈视角的供应链伙伴关系研究

科学技术的飞速发展、经济的全球化以及竞争的日益激烈，使得企业要想在市场上取得成功，就必须和供应商、客户建立紧密的伙伴关系，通过整体协作增强各节点企业的竞争力。对于供应链伙伴关系，可以从交易费用、资源观、博弈论等到不同视角进行研究，本文将从博弈的视角，通过企业间博弈的不同阶段，包括囚徒困境、鹿的陷阱以及单方承诺三个阶段，对供应链内企业间的伙伴关系进行探讨，揭示其内在规律。     

Control of intellectual assets in client relationships: implications for innovation

This empirical study of business‐to‐business service firms examines the determinants and effects of control rights to intellectual assets in a property rights theoretic framework. Regression analyses using survey data suggest that service suppliers that retain control over their intellectual output are more innovative. In long‐term relationships, service firms' clients may thus be better off balancing their need to control outsourced activities with the suppliers' incentives to invest in learning and innovation. Additionally, and aligned with property rights theoretic predictions, service suppliers' bargaining power and their indispensability in service projects are positively associated with their ability to retain control rights. In contrast, innovation capabilities are not very significant in determining control rights allocation between service suppliers and their clients. Copyright © 2008 John Wiley & Sons, Ltd.     

超产权理论刍议——兼评“超产权论与企业绩效”

产权理论是以产权为基本分析工具来研究企业的治理结构与绩效的关系。而超产权理论试图改变这一基本分析范式,以“竞争性”代替产权作为企业治理结构与绩效的基本分析工具。比较和分析这两种理论可看出,超产权理论所主张的竞争性分析方法并不能取代传统的产权分析,产权结构是决定企业治理结构和绩效的最基本制度因素,产权理论仍然是进行企业分析的合理有效的基本方法。     

深化对马克思企业理论的研究

深化对马克思企业理论的研究既有助于澄清一些人认为“马克思没有企业理论”的误解,也有助于纠正企业理论研究中“言必称西方”的倾向,还可以为我国的企业改革实践提供指导。研究的途径有“回到马克思”、“依据变化了的实际分析马克思企业理论的‘合理内核’与时代局限”、“批判性地借鉴西方经济学的企业理论”等。     

Use of Statistics in the Monetary Policy of the Czech National Bank: The Case of a Country in Transition

In the presented text the authors judge the importance of statistics in the monetary policy of the Czech National Bank (CNB) over the course of the economic transformation process, with particular consideration of changing statistical needs and the possibilities and limits of statistical data exploitation in the monetary analyses. The importance of statistics lies on the level of collection and processing of statistical information and on the level of use of statistical methods to analyse data. Since the start of the 1990s the requirements for statistics were significantly influenced by monetary policy. In the period 1990–1997, monetary targeting was the primary influential factor. Since 1998, the monetary policy is influenced by inflation targeting. Statistical priorities switched from monetary data to economy and financial market data. Much progress has been made in the use of statistical methods for analysing data. Statistics available at present cover the CNB's standard monetary-policy requirements and are on par with those in developed countries. Its further development will reflect the standard changes taking place in the more advanced countries.
