用全覆盖的区域政策构建大协调的发展新格局

自促进中部地区崛起的战略提出以后，我国已形成了全面覆盖的区域政策体系。本文对我国4大区域战略进行了详细阐述，勾画了东西南北中大协调、共发展的崭新格局；并对各省级区域内部的协调发展进行了初步研究。     

Relative Guarantees

Many real-world financial contracts have some sort of minimum rate of return guarantee included. One class of these guarantees is so-called relative guarantees, i.e., guarantees where the minimum guaranteed rate of return is given as a function of the stochastic return on a reference portfolio. These guarantees are the topic of this paper. We analyse a wide range of different functional specifications for the minimum guaranteed rate of return, hereunder both so-called maturity and multi-period guarantees. Several closed form solutions are presented.     

美国会计目标研究的历史考察及其对我们的启示

会计目标不仅是一个重要的理论问题,亦是一个重要的实际问题。美国是世界上研究会计目标最早、取得研究成果最丰富的国家之一。从美国会计学会1966年发表基本会计理论研究公告算起,美国从事会计目标研究已有30余年的历史。美国会计学会、会计原则委员会、特鲁布罗德委员会、财务会计准则委员会都对会计目标的研究作出过重要贡献,形成了像基本会计理论公告、APB第4号报告、特鲁布罗德报告和企业财务报告的目标等一系列研究成果。通过对美国会计目标研究历史的分析,我们从中可以得到如下三点启示: 第一,会计目标的研究与对会计本质的认识密不可分; 第二,会计目标研究应密切联系一定的社会经济环境; 第三,会计目标研究应采取理论分析与实证研究相结合的方法。     

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.     

The Long-run Effects of the Italian Pension Reforms

The paper analysesthe reforms of the Italian mandatory pension scheme for employeeslegislated in the 1990s. To assess the effects of the reforms,a microsimulation model calibrated on cross-section data is developed.The model is aimed at estimating the average income of a memberof a cohort, as well as the average per capita income of allindividuals alive in a given year. The long-run effects of thereform are analysed, comparing the characteristics of alternativefinancing schemes. A substantial improvement of the equity aswell as the long-run sustainability of the Italian public pensionschemes emerges. However, the dreary demographic scenario callsfor further tightening of eligibility rules sometime in the nextdecades if long-run sustainability of public debt is to be achieved.On the basis of sensitivity analysis, some changes aimed at hedgingthe system against unexpected shocks are suggested.     

Research notes and communications strategic planning as competitive advantage

Since 1970, over forty empirical studies have examined the performance consequences of formal strategic planning. This line of research has drawn heavy criticism from reviewers on methodological grounds, and has produced confusing, apparently contradictory results. This article reevaluates the planning-performance relationship from a resource perspective, arguing that strategic planning does not satisfy the criteria for sustainable competitive advantage– although it may produce economic value, it is easily imitated and may be substitutable. The article suggests that previous studies produced inconsistent results because they did not account for the dissemination of strategic planning over time, or for industry differences in strategic planning factor markets. An empirical test in two industries finds that formal strategic planning and financial performance are unrelated in a ‘planning equilibrium’ industry, but positively related in an industry with strategic planning factor market imperfections.     

Believing in employment discrimination: The case of Forrest Mims,Scientific American,and title VII protection

This article reviews the law regarding Title VII employment discrimination protection from religious discrimination. The issues surrounding the principal legal protection in this regard are explored in the context of a recent controversial case in which an author, Forrest Mims, was not hired as a regular contributor forScientific American magazine, ostensibly because of his belief in the theory of creation over the theory of evolution. The definition of what constitutes a protected religious belief or practice is seen to have expanded over time. However, a belief in creationism is not necessarily seen as being tantamount to a religious belief under present legal interpretation of Title VII. The implications of this finding for future needed Title VII revision are discussed.
