Relative risk aversion, relative prudence and comparative statics under uncertainty: The case of (μ, σ)‐preferences

From the expected‐utility approach, relative risk aversion being smaller than one and relative prudence being smaller than two emerge as preference restrictions that fully determine the optimal responses of decisions under uncertainty to certain shifts in probability distributions. We characterize the magnitudes of relative risk aversion and relative prudence in terms of the two‐parameter, mean‐standard deviation approach. We demonstrate that this characterization is instrumental in obtaining comparative static results in the two‐parameter setting. We further relate our findings to the results in the expected‐utility framework.     

Lies,damned lies and statistics: the accuracy of survey responses

That survey research is error prone is not a new idea and different varieties of non-sampling error have been investigated in the literature as well as consideration being given in many statistics textbooks to the issue of sampling error. The paper here considers research upon corporate environmental reporting. It compares information provided by corporate environmental reports with information that survey respondents claim their organization’s environmental report contains. This enables the accuracy of the claims to be assessed. Consideration is given to two different industries the Water industry and the Energy industry. Errors due to inaccurate reporting by survey respondents are shown to be relatively infrequent and respondents appear just about as likely to claim they report information that they do not, in fact, report as to fail to indicate that they report information that is, in fact, actually reported.     

烯烃装置的绩效分析—一种微观经济的比较研究方法

所罗门管理咨询公司（SAI）是成立于1981年一家美国咨询公司，其经营特色是通过研究企业（客户）绩效确定其获得成功的关键因素，并通过同类企业绩效对比研究的方法，为企业（客户）指明改进绩效跻身先进的途径和措施，创建20年来以其独有的服务特色和经营理念赢得了广大客户，行业覆盖面由初始的炼油，扩大到目前包括石油，化工，造纸，汽车制造，运输，电力，银行等多个领域，成为在某些行业，特别是炼,石化行业颇具声誉的咨询机构，其中企业绩效分析评估更是该公司时间最久，又最具领先地位的核心业务，即以石化行业中的烯烃工厂为例，就已八，九十家作为客户参与其每二年一次的绩效分析活动，我国于1998年开始有一家参与了ASI的第7次全球烯烃绩效分析，参评情况当时就受到了业内领导层重视，以国于1998年开始有一定参与了SAI的第7次全球烯烃绩效分析，参评情况当时就受到了业内领导层重视，以后陆续又有多家企业参加，使这一方法在国内有愈来愈大的影响，希望了解并对此感兴越的人士也逐渐增多，为了实践本刊关注新热点的报道方针，本刊在2000年即着大的影响，希望了解并对此感兴越的人士也逐渐增多，为了实践本直关注新热点的报道方针，本刊在2000年邓着手组织有关这方面的搞件，本文即为其中之一，由于出版安排的原因（其中也有尽先刊载SAI作者来稿的考虑），延至本期才得以达览，而其间，应《 乙烯工业》要求，在该刊2001年第1期上先行发表，则是为了配合中石化集团公司七展烯烃装置绩效比较分析活动的需要，所作出的适应性调整而为之的，请读者谅察，同时本刊热希望并允迎已尼参与此项工作的科技，经济工作者，充分利用本刊这个载体，就绩效分析这个题目，与读者进行更具体，更务实的沟通与交流。所罗门管理咨询公司（SAI）的烯烃装置绩效分析方法是一种将同行各装置进行相对比较，然后确定各装置在其产的相对位置的方法，该方法与国内现行的竞争力分析方法相比更具科学性和可比性，此方法中包含了许多国内企业比较陌生的概念和做法，在此对该方法的特点，作用以及参评装置在提供数据时应注意的问题作了简单介绍，并以国内较早参与此项工作的J装置为例，介绍了该方法进行了情况。

Construct measurement in strategic management research: illusion or reality?

Strategic management research has been characterized as placing less emphasis on construct measurement than other management subfields. In this work, we document the state of the art of measurement in strategic management research, and discuss the implications for interpreting the results of research in this field. To assess the breadth of measurement issues in the discipline, we conducted a content analysis of empirical strategic management articles published in leading journals in the period of 1998–2000. We found that few studies discuss reliability and validity issues, and empirical research in the field commonly relies on single‐indicator measures. Additionally, studies rarely address the problems of attenuation due to measurement error. We close with a discussion of the implications for future research and for interpreting prior work in strategic management. Copyright © 2004 John Wiley & Sons, Ltd.

More thinking on research methods for the resource‐based perspective

We re‐examine the benefits of using a broader set of research methods to address key questions associated with the resource‐based view (RBV) of the firm. In responding to Levitas and Chi, we consider how research inside organizations can complement and augment research relying on secondary data. Copyright © 2002 John Wiley & Sons, Ltd.     

Innovative productivity and returns to scale in the pharmaceutical industry

This study shows that firms in the pharmaceutical industry experience decreasing returns to scale in R & D as the level of R & D expenditures rises. The paper presents the results of our study of the innovative output of 16 pharmaceutical firms over a 19 year period. Given the strong correlation between R & D budgets and firm size, our study suggests the wave of mergers in the industry may yield less innovative productivity than managers expect.
