Social and organisational implications of CAD usage: a grounded theory in a fashion company

This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas.     

DS-optimal designs in one way ANOVA

Characterization and construction of optimal designs using the familiar optimality criteria, for example A-, D- and E-optimality are well studied in the literature. However the study of the Distance Optimality (DS-) criterion introduced by Sinha (1970) has very recently drawn attention of researchers. In the present article, we consider the singularly estimable full rank problem of estimating the full set of elementary treatment contrasts using the DS optimality criterion in the set up of a one way ANOVA model. Using a limit argument it turns out that a CRD in which difference between any two allocation numbers is at the most unity is uniquely DS-optimal. Acknowledgement. We are thankful to Prof. B. K. Sinha for suggesting the problem to us and many helpful discussions with him. We are also thankful to the referees for drawing our attention to the reference of Bischoff (1995) and many helpful comments.     

Executives’ Orientations as Indicators of Crisis Management Policies and Practices*

ABSTRACT The paper examines effects of executives’ orientations on crisis management awareness and practices, drawing on the simplicity and paradox management theories. It is suggested that a focus on single‐sided management constitutes an antecedent of crisis proneness. Employing a set of key corporate domains and based on a holistic organizational approach, the study aims at assessing the extent to which companies are crisis prone or prepared. In a sample of 82 Istaeli business and not‐for‐profit organizations it was found that human resource management, strategy, structure, and unlearning factors significantly predicted crisis preparedness. These results suggest that unlearning, despite a mere allusion to this correlate in the simplicity and paradox management theories, correlates better with crisis preparedness. By contrast, traditional strategy‐related and structural effects were marginally related to crisis management policies. Implications and suggestions for further research are proposed.

The Effects of Participation and Job-Relevant Information on the Relationship Between Evaluative Style and Job Satisfaction

This study investigates the intervening effects of budgetary participation and job-relevant information on the relationship between budget emphasis and job satisfaction. It proposes that budgetary participation and job-relevant information are endogenous to budget emphasis. Using the path analytical technique and based on a sample of 152 senior managers, the study found that budget emphasis has an insignificant direct effect on job satisfaction, but a strong indirect effect through job-relevant information and budgetary participation. The results also indicate that job-relevant information has an intervening effect on the relationship between participation and job satisfaction.     

Public-Private Partnerships and Prices: Evidence from Water Distribution in France

We use an original database of 5000 French local public authorities to explore the impact of organizational choice and performance as measured by consumer prices. In quantifying the impact of the choice of public-private partnerships (PPPs) on performance, we consider the related issue of the determinants of organizational choice. We estimate a switching regressions model to account for the endogeneity of organizational choice, and find that in our sample, (i) the choice by local public authorities to engage in a PPP is not random, and (ii) conditional on the choice of a PPP, consumer prices are significantly higher on average.     

HEDONIC PRICING MODELS FOR VEHICLE REGISTRATION MARKS

Abstract.  This paper attempts to link Chinese numerology to the determination of vehicle registration mark (VRM) prices in Hong Kong through the hedonic pricing analysis. The values of different patterns of the numbers and Roman alphabet letters are examined. We find that there is a very strong preference for the number '8', that visually appealing patterns add great values to a VRM and that the non-transferable VRMs are more expensive than transferable ones. We also show that their prices move in tandem with the Hang Seng Index. The findings suggest that the government can raise revenue by auctioning off intangible assets containing alphanumerical identification marks.     

离散选择模型的基本原理及其发展演进评介

离散选择模型的研究真正兴起于19世纪50年代末，属于微观计量经济学的范畴。该模型能够对个体和家庭行为进行经验性的统计分析，因而在经济学和其他社会科学中得到广泛的应用。本文从离散选择模型的基本性质及效用最大化的理论背景出发，指出logit模型虽然使用的是最早并且最为广泛的离散选择模型，但是其存在着三大局限性：不能表示随机口味的变化、暗含成比例的替代形式和不能处理不可观测因素在不同期间相关的情形。GEV（含嵌套logit）、probit和混合logit模型等其他的离散选择模型，很大程度上都是为了避免这些限制而产生并发展起来的。     

股东、政府及管理层之间的委托代理分析

传统意义上的委托代理理论是指单重委托代理理论，主要用来分析以私有产权和私有制为基础的公司制企业在经营权和所有权分离的背景下产生的公司治理问题。但在我国，国有企业从初始委托人（全体人民）到最终代理人（管理层）存在着多层的委托代理关系，企业内所有者缺位，所有权的监督比较薄弱，因此单重委托代理理论不适合用来分析我国的国有企业。运用双重委托代理理论对我国国有企业中的股东（全体人民）、政府及管理层之间的委托代理关系进行了分析而得到双重委托代理理论比单重委托代理理论更具解释力的结论。对委托代理模型的主要变量进行了讨论，并给出全民和政府分别作为委托人时的最优激励合同、政府侵占全民的租金及双重委托代理的总代理成本。
