Multiple-objective methods in regulatory decision making: A conceptual framework applied to U.S. automobile safety standards

Public policy making is a complex matter. Policy makers are charged with balancing a broad spectrum of competing objectives, reflecting in varying degrees the interests and aspirations of a diverse range of constituencies and stakeholders. Policy decisions have differential impacts on differing constituencies and the contributions of these impacts to objectives are frequently uncertain, difficult to quantify, and hotly disputed. Formal methods of decision analysis have been advanced as aids for coping with complexity and have been applied to some public policy issues, most notably the management of water resources. While formal methods have the apparent benefit of rationalizing the policy process and improving the efficacy and equity of policy decisions, serious questions remain concerning the acceptability and ultimate usefulness of formal analyses in the public arena. In this article we examine these questions in the context of policy making relating to government regulation of automobile designs for safety. We consider what would be involved in attempting to use a relatively modern, multiple-objective approach in this context. The key questions are how and, more importantly, why multiple-objective methods might be used. The article begins with an illustrative case study, describes the current policymaking process, identifies the parties involved in and affected by this process, elicits key objectives, looks briefly at some scalar-objective approaches, and then outlines a multiple-objective approach. The framework developed arguably is useful in assisting policy making, at least at a qualitative level. Issues which impede a more quantitative resolution of this framework are discussed. This article is intended as a pilot study which may promote research toward the achievement of a useable multiple-objective procedure applicable in the public domain.     

通过预防召回获得边际竞争优势

对消费品公司来说，产品召回是一个严重的问题。在美国，每年因为安全原因有成千上万的产品被召回。如图1所示，在1999年和2001年间，14个主要类别的消费品的召回数量在稳定地增加。保守地估计，每个公司召回的平均成本多于800万美元，包括对消费者的赔偿。对消费品行业来说，这可以转化为多于60亿美元的成本，这个估计不包括市场信誉造成的销售损失和失去的市场份额。     

Ethical or practical: An empirical study of students' choices in simulated business scenarios

Graduate and undergraduate students were asked to evaluate the ethicality and practicality of the lead character in several case scenarios. Students' responses indicated they believed practicality was more important than ethicality. The majority of students were able to determine the correct ethicality of the cases presented to them. The authors conclude that more research is needed in the antecedents of a student's value system.Dr. White is U.C.

AN APPROACH TO LINKING AN ECOLOGICAL VEGETATION MODEL TO AN AGRICULTURAL ECONOMIC MODEL

Agricultural policy measures are directed increasingly towards encouraging production systems that are deemed to be favourable for ecologically valued plant communities and species. This paper presents an approach to linking an ecological model of vegetation with a regional economic model of agricultural production to provide a means of estimating the costs of achieving a given area of a desired vegetation type. This is demonstrated by an empirical study of heather and hay meadow conservation in the River Tyne catchment in northern England. The results show that policy measures need to take account both of spatial linkages within agriculture and temporal links between ecological processes and agricultural productivity.     

Subsampling the distribution of diverging statistics with applications to finance

In this paper we propose a subsampling estimator for the distribution of statistics diverging at either known or unknown rates when the underlying time series is strictly stationary and strong mixing. Based on our results we provide a detailed discussion of how to estimate extreme order statistics with dependent data and present two applications to assessing financial market risk. Our method performs well in estimating Value at Risk and provides a superior alternative to Hill's estimator in operationalizing Safety First portfolio selection.     

Do New Product Development Managers in Large or High-Market-Share Firms Perceive Marketing-R&D Interface Principles Differently?

In the quest for successful innovation, the importance of the R&Dlmarketing interface is virtually unquestioned. For many organizations, however, effective integration of technical and marketing functions is difficult, if not impossible. Despite seemingly widespread understanding of fundamental new product principles, some companies still manage to gain a larger share of the market than their competitors. This raises the question of whether managers in more successful companies have special insights into R&D'/'marketing interface principles that give them an edge over their competitors. To gain a better understanding of managers' perceptions of new product principles defined in the academic literature, Ted Haggblom, Roger J. Calantone, and C. Anthony Di Benedetto conducted a survey of 687 nonacademic members of the Product Development and Management Association. The basis for the survey was a set of 78 product management principles compiled from a search of more than 500 books and articles from various disciplines. From this survey, 14 of the 78 principles were selected as relevant to the study reported in this article. The principles discussed in this article involve such issues as resistance to change, short-term orientation, communication and trust between marketing and technical people, the effect of centralized decision-making on innovation, the importance of open communication flows, senior management's role in the R&D I marketing interface, and the necessity of a product champion. The primary quesstion addressed in this study is whether managers from successful companies perceive these principles differently from managers of less successful firms. The study provides partial support for the proposition that managers' perceptions of these new product principles depend on their company's success. In other words, the survey results suggest that managers in companies with higher market shares tend to agree more strongly with these principles than their counterparts in less successful firms. The study also explores the relationship between firm size and agreement with these principles of new product success. Specifically, the study assesses whether the perceptions of managers from smaller, more entrepreneurial companies differ from those of managers in larger companies. Although managers from small and large firms may view these principles from different perspectives, there were no statistically significant differences in the perceptions of managers from small and large firms.
