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. Gilbert, Jr. is a doctoral student in the Strategic Management and Organization program, School of Management, University of Minnesota, and also serves as an Instructor in Strategic Management and a Research Associate in the Strategic Management Research Center.  相似文献

When our society holds widely shared norms and values, we can agree on what constitutes unethical business practices. To the extent our social consensus is unraveling, agreement becomes increasingly problematic. Unfortunately, mainstream Western moral philosophy offers no guidance in this situation. We must therefore begin to focus on the types of social relationships that must exist for there to be agreement on what is right, good and just. This line of argument is, at best, merely suggested in discussions and articles on business ethics. Jonathan B. King is Associate Professor of Managment at the College of Business at Oregon State University. He received his B.A. in philosophy from Antioch College (1965); subsequently served for eight years as an officer in the United States Navy; received his M.B.A. (1975) and Ph.D. (1980) in Business, Government and Society from the University of Washington. His primary research interests are in the areas of epistemology and moral philosophy — e.g., the contribution of the liberal arts to interpretive thought, the sociology of moral knowledge, and the organizational distortion of information. His most important publications are: Teaching Business Ethics, Exchange1984 and A Case for the Humanities Perspective, Organizational Behavior Teaching Journal1984  相似文献

Summary This paper considers the relationship between economic size and vulnerability to external disturbances. In order to analyze this issue effectively a model comprising three different-sized economies is constructed. The issue of economic size and insulation is approached from this alternative perspectives depending upon the relative size of (a) the `recipient' country and (b) the transmitting country. The results of the analysis indicate that, contrary to popular belief, a small country under floating exchange rates is less severely affected by external economic events than a large economy regardless of the type of external disturbance and the degree of domestic wage indexation.This paper has been improved by the helpful comments of a referee. We alone are solely responsible for all remaining errors.  相似文献

For an arbitrary subset A of the finite state space 5 of a Markov chain the so–called embedded matrix P A is introduced. By use of these matrices formulas expressing all kinds of probabilities can be written down almost automatically, and calculated very easily on a computer. Also derivations can be given very systematically.  相似文献

In this paper, we discuss the properties of preliminary test estimators (PTE) of the parameters of simple linear model with measurement error (ME model) when the slope of the linear model is suspected to be zero. Expressions of the bias, MSE and efficiencies are obtained under conditional as well as unconditional situations with known reliability coefficient. Conditional model results are compared to the standard model without measurement error. We also provide the unconditional model analysis in finite samples. Asymptotic theory under local alternatives is developed when the variance of measurement error or the ratio of the variance of the model error relative to the variance of the measurement error is known. Asymptotic expressions of bias and MSE of the estimators along with their efficiencies are obtained. In every case, it is shown that the measurement error tend to increase the variability of the estimators compared to the estimators without measurement error. Graphs and tables are provided to see these results and to determine optimum level of significance for minimum guaranteed efficiency. Received October 2001 RID="*" ID="*"  A. K. Md. E.

We examine the two traditions of content analysis: the first in which one substitutes words of a text with categories, and the second in which one looks for clusters of words that may refer to a theme. In the first tradition, preexisting dictionary categories give meaning to the words; in the second, meaning comes after the fact. Preexisting dictionary categories (the substitution model) are calibrated instruments applied within experimental designs that leave no space for doubt; meanwhile, the ability of the correlational model to conjure up complex themes from fragments of a text yields no unique solution. These differences have bearings on the production of new social knowledge. We expound on the epistemological foundations of the two traditions of interpretation and draw from them decision rules upon which one may rely for choosing among appropriate content-analytic tactics. Two reasons make this essay timely and critical: (1) the increasing variety of new content-analyticsoftware for particular purposes and (2) the almost exclusive focusing on software and technology at the expense of adjusting the choice of the software to the nature of the text. Two studies, one in historiometry, the other in autobiography, illustrate the liabilities and benefits of the two models of content analysis.  相似文献

Many employers are extending workplace rights by allowing for more employee voice in decision making. Numerous unionized organizations have established formal worker participation processes to help achieve this end and to improve organizational performance. Based largely on theory, such processes are normally designed to operate independently from the bargaining process. The purpose of this study was to examine the relationship between participation and bargaining processes, and the effect of this relationship on workplace satisfaction. A total of 712 Midwest union officials were surveyed, and the results indicate that the processes tend to become integrated in the workplace. Further, union officials' workplace satisfaction was greater where formal worker participation is institutionalized within the bargaining process.  相似文献

Summary The exact mean square error for the ratio estimator of a finite population total based on simple random sampling without replacement is shown to have an expected value less than that of the variance of the ratio estimator based on Midzuno’s scheme, under a usual super-population model.  相似文献

This study explores the effects of task structure and leader power on participative leadership across Australian, African, Papua-New Guinea and Pacific Island managers. Managers in all national groups are more participative in situations of low structure and low power than for high structure and high power, respectively. Participation in situations of low structure and low power declines in the order: Australia, Africa, Papua-New Guinea, Pacific Islands. It is argued that this effect is an instrumental effect of managerial education, rather than being culturally determined. the Vroom-Yetton leadership methodology is used to measure participation levels. Subjects are a total of 150 middle-level managers attending management education courses.  相似文献
