Approximating unanimity orderings: An application to Lorenz dominance

Stochastic dominance and Lorenz dominance are examples of orderings which require unanimous agreement among an infinite set of indices. This paper considers various subsets of inequality measures that respect Lorenz dominance, and assesses the extent to which a small number of indices can reproduce the Lorenz ordering. Using income data for 80 countries, our results suggest that Lorenz dominance can be predicted with 99% accuracy using just 3 or 4 inequality measures, as long as two of them focus on the extreme upper and lower tails of the distribution. In contrast, confining attention to the index families and parameter ranges normally considered may fail to detect the majority of occasions when Lorenz curves intersect. These results lead us to question the faith placed in procedures based on a finite set of inequality indices, and to suggest that similar lessons will apply to other types of unanimity orderings.     

Ethics and Australian International Business which way to Asia?

In an era of domestic and economic reform wherein deregulation/privatisation becomes a priority, short shift has too often been given to evaluative analyses of business activities. Evaluative monitoring and oversight are especially needful in highly competitive international business environments, where the temptations are very strong to adjudge individual effectiveness by the sole criterion of the bottom line. But what additional or alternative criteria should be administered, and by whom, is less clear. That any but the most vague Judeo-Christian or secular ethical standards are applicable (e.g. notions of fairness) is widely contested. The debate is significantly only widened when doing business across national borders involving peoples from different cultures and languages. This section is devoted to explicating the normative role of international codes of conduct for guiding the decision making of managers involved in multinational operations, and clarifying what ethical frameworks are available to the international manager for taking decisions which require selecting actions inconsistent with either home or host country demands.Daniel W.

Corporate Strategy and ethics

Corporate Strategy has emerged as a central metaphor for private-sector enterprise. Given inherent imperfections in markets, one important question to consider is how well the practice of Corporate Strategy contributes to social welfare. An account of the implicit morality of free markets is developed as a standard against which two particular, second best solutions to market imperfections — namely, American federal antitrust policy and Corporate Strategy — are compared. Corporate Strategy is subsequently evaluated in terms of the fundamental principles of Rawls' theory of justice. In both analyses, Corporate Strategy is found to depart significantly and systematically from the standards of social justice. An alternative principle, grounded in the concept of duty, is introduced as a means for reconceptualizing Corporate Strategy.Daniel R.

Measuring Hospital Performance in the Presence of Quasi-Fixed Inputs: An Analysis of Québec Hospitals

This research proposes an approach to measure hospital performance based on a generalization of Banker and Morey (1986) and Førsund (1996). This approach considers quasi-fixed inputs explicitly, calculates their implicit cost, and quantifies returns to scale. The performance measure is decomposed into allocative and technical inefficiencies. Based on a very complete data set of Québec hospitals, we find that significant inefficiencies of up to 17% ($700 CAN million) could have been saved through improved performance. Postestimation analyses that include qualitative measures of care suggest that differences in performance are attributable to differences in management or unobservable quality of care rather than patient case mix.     

Canadian and American Reactions to Drug and Alcohol Testing Programs in the Workplace

We investigated U.S. and Canadian reactions to workplace drug and alcohol testing programs. Canadian truck drivers (n = 183) deemed drug and alcohol testing policies less fair, and were less accepting of these policies, than their American counterparts (n = 153). We also compared the perspectives of recipients versus third-party observers with regard to their reactions to a drug testing program. Unlike the pattern observed among American observers, the responses by Canadian observers were highly similar to those of the recipients. Canadian observers were more inclined to file a formal protest regarding the implementation of a drug and alcohol testing program than were U.S. observers. The results also showed that procedural and interactional justice principles contributed to the program's fairness, acceptance, and lower levels of protest intentions in both Canada and the United States. We propose that scholars and practitioners can gain a better understanding of multinational reactions to drug and alcohol testing by considering not only cultural but also historical, social, political, and other environmental factors that can shape reactions to personnel practices.     

Linear Programming Models for the Measurement of Environmental Performance of Firms—Concepts and Empirical Results

I use linear programming models to define standardised, aggregate environmental performance indicators for firms. The best practice frontier obtained corresponds to decision making units showing the best environmental behaviour. Results are obtained with data from U.S. fossil fuel-fired electric utilities, starting from four alternative models, among which are three linear programming models that differ in the way they account for undesirable outputs (pollutants) and resources used as inputs. The results indicate important discrepancies in the rankings obtained by the four models. Rather than contradictory, these results are interpreted as giving different, complementary kinds of information, that should all be taken into account by public decision-makers.     

The Morishima gross elasticity of substitution

We show that the Hotelling–Lau elasticity of substitution, an extension of the Allen–Uzawa elasticity to allow for optimal output-quantity (or utility) responses to changes in factor prices, inherits all of the failings of the Allen–Uzawa elasticity identified by Blackorby and Russell [(1989) Am Econ Rev 79: 882–888]. An analogous extension of the Morishima elasticity of substitution to allow for output quantity changes preserves the salient properties of the original Hicksian notion of elasticity of substitution. We thank Paolo Bertoletti for drawing our attention to the issue addressed in this paper and for his comments on an earlier draft.     

寻求HR的职业发展阶梯

拓展你的职业生涯,从赢得上司的尊重开始。当人们试图使自己的事业发展更进一步时,许多人将注意力集中到寻找新的雇主、接受更高级的教育和通过专业协会增加自己的交际网络上来。但是,这些方法并不是提升职业生涯的最好方式。对于人力资源从业者,尤其是刚刚开始新的工作或者正处于基层职位的人来说,另一个有效的提升方式是在职发展计划。人力资源从业者可以在工作中磨练重要的技能,并从自己的经理或者主管那里获得职业发展的机会,这其实也是最好的方法之一。
