To examine the relationship between participation in a wellness program and the amount of absenteeism and medical claims, seven years of retrospective absenteeism and medical claims records were collected for 207 employees (pre- and postwellness intervention) and entered into a database. A proportional stratified random sample of workers by wellness participation was selected. While there was no significant change in the amount of sick leave taken over time, a log transformation revealed a significant increase in the dollar amount of medical claims over time, particularly for the middle-aged group of employees. This confirms that wellness intervention slowed the rate of increasing claims among middle-aged participants after just three years of wellness intervention.  相似文献

The elimination of unneeded services is a key to reducing medical costs and enhancing quality of care. Diagnostic tests have been a target of efforts to reduce costs primarily because they are discretionary and often appear to be unnecessary. Believing that the concept of prior review for many diagnostic tests is a good one, this pilot study sought to evaluate prospectively the propriety of diagnostic tests ordered during the first half of 1989 on individuals insured through a major insurance carrier. A physician review found that 21% of the tests were deemed inappropriate, leading to the conclusion that prospective review can be an effective means of screening inappropriately ordered tests.  相似文献

Summary We study a strategic version of the neoclassical growth model under possible production uncertainty. For a general specification of the problem, we establish (i) the existence of stationary Markov equilibria in pure strategies for the discounted game, and (ii) the convergence, under a boundedness condition, of discounted equilibrium strategies to a pure strategy stationary Markovian equilibrium of the undiscounted game as the discount factor tends to unity. The same techniques can be used to prove that such convergence also obtains in all finitestate, finite-action stochastic games satisfying a certain full communicability condition. These results are of special interest since there are well known examples in the literature in which the limit of discounted equilibria fails to be an equilibrium of the undiscounted game.We are grateful to Marcus Berliant, M. Ali Khan, Mukul Majumdar, and an anonymous referee for helpful suggestions, and to Bonnie Huck for technical assistance.

Returns generated with small firm mutual fund data are used to examine the extent to which identification of a small firm effect is due to the difficulty in measuring the direct and indirect transaction costs involved in investing in the common shares of small capitalization stocks. Little if any evidence of the excess risk-adjusted returns is obtained for either of the period 1978–1983, when the small firm effect was observed, or the period 1984–1989, when it was not. The small firm effect may therefore be attributed to (1) higher direct transaction costs including bid-ask spread and broker fees and (2) higher indirect transaction costs including portfolio management expenses and market impact costs.The authors thank an anonymous referee for helpful comments on an earlier version of this paper, and Brett Salazar for valuable assistance in data collection. Errors remain our own.  相似文献

In a recent important book,The Ethics of International Business, Tom Donaldson argues that multinational corporations (as well as individuals and nationstates) must, at a minimum, respect international human rights. For a purported right to be such a fundamental right it must satisfy three conditions. Donaldson calls the third condition the fairness-affordability condition. The affordability part of this condition holds that moral agents must be capable of paying for the burdens and responsibilities that a proposed human right would impose. If this is impossible, then the purported right is not an international human right.I argue that Donaldson's affordability condition is subject to four objections which reveal its untenability as one of the conditions upon which identification of international human rights must rest. I offer another way of treating problems of affordability and capability when it comes to such rights that all moral agents must respect.George G. Brenkert is Professor of Philosophy at the University of Tennessee/Knoxville. He has recently completed a book,Political Freedom, to be published by Routledge. His current research focuses on issues in business ethics.  相似文献

The paper is a response to Richard De George's essay, Theological Ethics and Business Ethics. It defends the possibility of theologically oriented approaches to business ethics by pointing out certain deficiencies in business ethics narrowly based on the premisses of analytic moral philosophy. In particular it argues, in a manner consistent with Alasdair MacIntyre's After Virtue (1981), that such a program of business ethics is insufficiently critical of its own roots in the social fiction of bureaucratic rationality. After showing how this ideology governs De George's negative judgments on theological approaches to business ethics, the author outlines a program of critical reflection that would draw from the intellectual traditions of both theology and philosophy in order to facilitate a dialogue in business ethics that no longer is captive in the Iron Cage of bureaucratic rationality.

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
