Proponents of state antitakeover legislation argue that previous empirical tests by financial economists of the wealth effects of Pennsylvania's 1990 antitakeover law are biased. We show that the proponents are correct. In particular, firm size, event-time clustering, and non-synchronous trading effects account for the wealth decreases reported in earlier studies. We also show, however, that both proponents and critics of the Pennsylvania legislation have ignored the earliest press release about it. The wealth effect associated with this announcement is negative, large, and statistically significant. These results therefore are consistent with the hypothesis that the Pennsylvania law decreased company values and with the hypothesis that the initial market reaction is an unbiased estimate of the law's effect on firm values.  相似文献

A bstract The article traces the development of the market for hospital services through evolutionary stages to the present emphasis on merger and consolidation. Examination of the traditional principles of antitrust analysis suggests they are sufficiently flexible to warrant their application in evaluating the competitive impact of hospital mergers.  相似文献

In search of the meaning of entrepreneurship   总被引:9,自引:0,他引:9  
This paper is an attempt to build a bridge between the popular and the academic usage of the terms entrepreneur and entrepreneurship, and to identify the raw materials needed to construct an interpretive framework capable of illuminating the nature of entrepreneurship and its role in economic theory. We review briefly the contributions made to this topic by Cantillon, Schumpeter, Schultz and Kirzner. We advance a synthetic definition of the entrepreneur as someone who specializes in taking responsibility for and making judgemental decisions that affect the location, the form, and the use of goods, resources, or institutions. We then conclude with some observations on the basic choice confronting economics regarding the place of entrepreneurship in economic analysis.  相似文献

Modern professionals are engaged in making things better, but the specific advances on the micro-level are increasingly undercut by problems on the macro-level. The content of this better is typically guided by values such as efficiency, productivity or cost-effectiveness, which are essentially output over input ratios unable to account for how a specific improvement will fit into the broader human, social and ecological contexts. Hence, micro-level advances lead to fragmentation and a loss of harmony, compatibility and conviviality. The situation is further complicated by the fact that, culturally speaking, science and technology have become good in themselves, making reasonable discourse difficult. This paper concludes with an analogy from an earlier epoch suggesting how the situation may be resolved.

Fair markets     
The paper challenges a minimalist strategy in business ethics that maintains if it's legal, it's moral. In hard cases, judges decide legal issues by appealing to moral ideals. Investigation shows that the bedrock concept is fairness. Often judges define fairness in terms of non-coerciveness or equality of bargaining power. The prudent manager must look beyond the legal department to the ethical notion of fairness. Moreover, if the courts were to consistently appeal to non-coerciveness and equality of bargaining power, some practices now considered morally acceptable would be neither moral nor legal. Norman E. Bowie is Professor of Philosophy and Director of the Center for the Study of Values at the University of Delaware. He is the author of numerous articles on business ethics and social and political philosophy and of Business Ethics, Making Ethical Decisions (ed.), The Tradition of Philosophy (co-ed.), and Ethical Theory and Business (co-ed.).  相似文献

The increase of scandals in the business sector is forcing many companies to examine their corporate ethical behavior with a view toward rebuilding their corporate value system. This article describes how value-system reconstruction must proceed in a company and demonstrates that corporate ethics can only become plausible if based on a corporate ethical ethos. It outlines a five-step development plan of management strategies toward rebuilding a company's value system on this corporate ethos through: corporate policy and strategy reformulation; corporate ethical code promulgation and value-statement formulation; management ethical training and corporate ethical education; and corporate ethical performance evaluation. The role of the corporate ethical consultant is also outlined to illustrate how corporate ethical consulting can provide the specialized services designed to insure an enduring management ethical upgrading and to improve a company's corporate ethical performance record. The discussion indicates how corporate ethical consulting promotes good business through its capacity to deliver industry credibility and company security.

Constant Market Share (CMS) analysis is a popular tool for analyzing changes in exports of a country. Nevertheless, its theoretical foundations (and policy relevance) have been questioned. In this paper, we provide such a foundation by relating CMS analysis to a two-stage homothetic demand model. An indication of the empirical relevance of this relationship is given by comparing the CMS analysis with a two-stage Constant Elasticity of Substitution demand model applied to 1972–1976 data of the Economic and Social Commission for Asia and the Pacific (ESCAP).Paper presented at the XX-th world conference of the Applied Econometric Association in Istanbul, December 1986. The research reported in this paper was carried out as part of the project Disequi-librium and Equilibrium in Demand and Supply, which is approved by the Dutch Office of Education and Sciences. Ivo J. Steyn and Philip A. ten Cate provided excellent research assistance. We thank an anonymous referee for helpful comments.  相似文献

"This study surveys the policy issues associated with urbanization following the abolition of the pass laws [in South Africa]. The demographic background is briefly sketched. Using neo-classical analysis as a starting point, particular attention is paid to the present inefficiencies of city form associated with segregation. It is argued that current planning procedures are in danger of perpetuating or even worsening the situation. Obstacles to employment generation are considered and transport, local government and housing issues are discussed. On every front, urbanization policy is unstable and, even in the short term, there will be pressures to change it."  相似文献

"A projection model based on a multivariate continuous state, stochastic process is presented. The model allows multiple time-varying covariates to be used so parameters can be estimated from time series information on health changes and mortality, and their interaction. Health changes are simulated by altering parameters controlling the age trajectory and diffusion of risk factor means, variances, and covariances....By increasing the information used in projections it may be possible to better (a) anticipate the state of health at extreme ages, (b) forecast changes in health at specific ages over time, (c) stimulate the effects of specific interventions, and (d) determine the sensitivity of outcomes to a range of interventions."  相似文献

The critical state of the hospital industry, as previously described, generates a difficult decision environment for the materiel manager and those in the purchasing function. The unique life- and death circumstances of hospitals impose a further onus on those who manage them. In the name of saving lives, they can find a convenient excuse to disregard all moral principles, forgetting the Socratic dictum "it is not enough that one lives, but that one lives well." Without the moral "right stuff," they can easily give in to the seductions of momentary gains and glory through ethical short-cuts. There is wisdom and consolation in the words that "nice guys may appear to finish last, but usually they're running in a different race." Studies have established a direct relationship between corporate excellence and ethical values. The reality of competition in the hospital industry dictates that the integration of ethics into the life of the organization should happen by design and not by accident. This is what is meant by strategy. If hospitals would strive for excellence to survive and grow, they should have a strategy with a mission statement that also embodies its moral values and moral agenda. Such an approach does not guarantee that an organization will become immune to moral contamination, but it does provide an antidote.  相似文献
