Conclusions Unlike McKenzie and Tullock, we do not know how personsshould treat their bodily organs or what is an ideal exit. That depends upon their utility goals, which are defined in output terms specific to the decision maker. We contend that the body is an input into the utility production process, and therefore, as with any input, it must be maintained and repaired at a level consistent with the output goals for maximization of utility. Thus, from this framework, it is quite consistent for a person to die with healthy organs without any thought of belief in reincarnation or the desire to bequeath one's bodily organs to others, or religious values. Self interest is all that must prevail.Also, the fact that there are interrelationships between the organs in the system, and at points these relationships take on fixed factor characteristics such that reduced levels of operation in one organ can create disorientation or coma or damage to other organs, means that the body cannot die as M-T suggest. Zero capacity for all organs at death is a technical impossibility as well as being inconsistent with the output goals of utility maximizers. 相似文献

The discussion of industrial democracy in Britain has exploded in the last few years, but the result has been to write an agenda which has still to be worked through, not to reveal a consensus which can be written into action at once. 相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling 总被引:1,自引:0,他引:1
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework. 相似文献

Measures developed for the analysis of corporate diversification have become fundamental to a broad range of strategy research. This paper examines the content validity of the two most widely used continuous measures of related diversification—the related component of the entropy index and the concentric index—and raises fundamental questions about their validity as indicators of portfolio relatedness. These questions are not driven by the use of SIC data for estimation of the indexes; they involve validity problems intrinsic to the construction of the measures. The related component of entropy and the concentric index are sensitive to features of corporate portfolio composition that may not be directly linked to portfolio relatedness. These sensitivities can create important ambiguities in strategy research. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

The expected restructuring of Asian corporations in the aftermath of the 1997 financial crisis has not materialized. This paper argues that restructuring in Asia will depend upon two institutional changes. First, the creation of high quality institutions that promotes the growth of new entrants and provides incentives to incumbents to restructure and or exit. Second, that the market scope of dominant incumbents be confronted and limited. The first condition creates pathways for new organizational populations to enter the economy and the second ensures room for their growth. The current debate emphasizes the former but neglects the latter. The absence of either inhibits the rate and direction of restructuring for two reasons. First, incumbents may lack the incentive and ability to exit or transform their structures and, secondly, incumbents can create a ‘blocking coalition’ to diminish competition from new entrants. 相似文献

Der vorliegende Beitrag fragt nach der demographischen Struktur der zentralen akademischen Akteure der Kommunikationswissenschaft
in Deutschland und nach m?glichen Ver?nderungen dieser Struktur in den letzten 50 Jahren. Die Analyse zeigt zum einen, dass
von einem einheitlichen Zugang zum Hochschullehrerberuf nach wie vor keine Rede sein kann, und zum anderen, dass das Fach
vor einer demographischen Herausforderung steht. Die Kommunikationswissenschaft hat sich durch Akademisierung und ?Versozialwissenschaftlichung?
von ihren Wurzeln gel?st. War Berufserfahrung im Medienbereich bis in die 1960er Jahre Voraussetzung für eine Berufung, verfügt
heute nur noch eine Minderheit über solche Erfahrungen. Da die Existenz des Faches im Rahmen der Universit?t auch von der
Nachfrage der Studierenden abh?ngt, kann man über die Folgen des anstehenden Generationswechsels nur spekulieren. In jedem
Fall fehlt es an formal für die Hochschullehrerlaufbahn qualifiziertem Nachwuchs. Deshalb sind erhebliche Anstrengungen erforderlich,
wenn der Boom im letzten Drittel des 20. Jahrhunderts sich nicht als Seifenblase erweisen soll. 相似文献

The Government has decided that referenda will be held in three northern regions of England regarding the establishment of elected regional assemblies. If these are established, the areas with two-tier local government would be converted to unitary structures. The Government asserts that this would be necessary because the retention of the two tiers would be the retention of one tier too many, but offers no evidence to back up this assertion. This assertion has been tested by an analysis of the Audit Commission's Comprehensive Performance Assessment (CPA) ratings for the single tier and county councils, which shows that the counties have achieved better assessments than the other principal authorities. In addition, the Boundary Committee has been advised by the Government to use a costing model which is seriously inadequate: transition costs are ignored and the basis for assessing on-going costs is extremely narrow. Transition costs would be at least £110 per resident in the two-tier areas if there were to be three unitary councils for each county area, and there is no reasonable prospect that there would in fact be on-going savings except with unitary counties. 相似文献

The leaf tobacco marketplace is highly organized. Prior to 1940, the few large tobacco companies controlled that organization explicitly. The question is whether this organization set oligopsonistic leaf prices or minimized production and transaction costs. A model of joint oligopsonyoligopoly shows that pricing of cigarettes and leaf tobacco was unified: oligopolistic cigarette pricing was sufficient to curtail both cigarette production and leaf purchases. The companies could just bid in the market for the leaf necessary for that cigarette production rate.Prima facie, the organization was not for oligopsony coordination. The implied econometric model of pricing fits observed behavior well.Malcolm Boyd, Dennis Carlton, John Garen, Stephen Karlson, Li Way Lee, An-loh Lin, Robert Miller, Stephen Spurr and the referee have given me thoughtful, perceptive and useful comments. I am pleased to acknowledge their involvement without implicating them in whatever errors remain. 相似文献
