Three-dimensional representation of company business and investigational activities

This paper describes a management aid devised to illustrate the inter-relationships between present company business activities and the investigational activities of the various company R&D functions. It is based on the- construction of a three-dimensional model in which the raw material, process and market parameters are the axes. Use of the model can facilitate project definition and selection in R and D departments and can be extended as a management aid in studies of R & D resource allocation and acquisition studies.     

Structural Uncertainty and Pollution Control: Optimal Stringency with Unknown Pollution Sources

We relax the common assumption that regulators know the structural relationship between emissions and ambient air quality with certainty. We find that uncertainty over this relationship can manifest as a unique form of multiplicative uncertainty in the marginal damages from emissions. We show how the optimal stringency of environmental regulation depends on this structural uncertainty. We also show how new information, like the discovery of previously unknown emission sources, can counterintuitively lead to increases in both optimal emissions and ambient pollution levels.     

半导体厂商生产节能芯片设立新标准

德州仪器(TI)的最新半导体加工厂本月底将开始安装生产设备,与该公司以前的加工厂相比,它生产单位晶圆可节能20％。此举初步可为TI节约能源成本支出 100万美元,当该加工厂达到满负荷生产时,每年最多可节约能源成本支出400万美元。     

Dissecting the Random Component of Utility

We illustrate and discuss several general issues associated with the random component of utility, or more generally unobserved variability. We posit a general conceptual framework that suggests a variance components view as an appropriate structure for unobserved variability. This framework suggests that unobserved heterogeneity is only one component of unobserved variability; hence, a more general view is required. We review a considerable amount of empirical research that suggests that random components are unlikely to be independent of systematic components, and random component variances are unlikely to be constant between or within individuals, time periods, locations, etc. We also review evidence that random components are functions of (elements of) systematic components. The latter suggests considerable caution in the use and interpretation of complex choice model specifications, in particular recently introduced forms of random parameter models that purport to estimate distributions of preference parameters. Several areas for future research are identified and discussed.     

Demystifying demotion: A look at the psychological and economic consequences on the demotee

Given the high levels of attrition in the teaching profession there is a need for research to better understand factors that lead to greater teacher well-being and engagement. The present study explores the roles of coping and buoyancy in predicting teacher well-being and engagement. In particular, a process model is hypothesized in which the use of ‘direct’ coping strategies (mastery orientation and planning) predict high levels of buoyancy, well-being, and engagement, while ‘palliative’ coping strategies (self-handicapping and failure avoidance) predict low buoyancy, well-being, and engagement. Amongst a sample of 515 teachers from 18 schools, results generally supported this model with particularly strong direct effects for buoyancy and strong direct and indirect effects for mastery orientation. Failure avoidance, self-handicapping, and planning also produced significant direct and/or indirect effects via buoyancy on teacher well-being and engagement. Implications for school executives and future research are discussed.

Self–Interest and Business Ethics: Some Lessons of the Recent Corporate Scandals

The recent accounting scandals at Enron, WorldCom, and other corporations have helped to fuel a massive loss of confidence in the integrity of American business and have contributed to a very sharp decline in the U.S. stock market. Inasmuch as these events have brought ethical questions about business to the forefront in the media and public consciousness as never before, they are of signal importance for the field of business ethics. I offer some observations and conjectures about the bearing of the recent scandals on the literature on business ethics. I defend the following contentions:1. Recent events reveal serious weaknesses of the stakeholder theory about the social responsibilities of business which lacks prohibitions against fraud and deception. This is a glaring deficiency of standard versions of the stakeholder theory, but it is easily remedied by adding explicit prohibitions against fraud and deception. In addition, recent events highlight the stakeholder theory's very naive and unrealistic hopes and expectations for business executives as moral arbiters and agents of social improvement.2. Recent events do not constitute an objection to the shareholder theory about the social responsibilities of business, however, these events make evident the implausibility of strong versions of the invisible hand theory.3. Schemes of payment and reward often create perverse incentives for individuals to engage in unethical conduct.4. Both the shareholder theory and the stakeholder theory need to add a constraint that requires executives to respect the professional obligations of employees.     

Vulture Investors, Predators of the 90s: An Ethical Examination

Investment in financially distressed companies has taken place since the end of the depression. But a new breed of predatory activist investors called "vultures" has emerged in recent years. They take sizable debt positions in insolvent companies with the intention of significantly increasing the value of their investment through aggressive negotiation either in bankruptcy or in pre-bankruptcy restructurings. Predators thrive on adversarial conflict. Vulture investment is legal, but is it morally acceptable? This paper argues that the strategies and tactics of vultures may be very unpleasant, but in themselves these are insufficient grounds for moral censure.
