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

A methodology for improving the process of selection and development of scientists and engineers for management is presented. This involves (1) specifying the R&D management role in terms of both behavior and style; (2) utilizing such a specification to estimate ‘probabilities of trainability’ and (3) employing the probabilities as criteria for the allocation of resources among managerial selection efforts versus training and development.  相似文献

One of the most effective tools of promotion in industrial markets, though often misused and little understood, is the proper use of direct mail. This article focuses upon the major considerations, with numerous examples, for planning and executing different direct mail programs.  相似文献

Conditional and Unconditional Conservatism:Concepts and Modeling   总被引:15,自引:1,他引:15  
We develop a model that captures the distinct natures of and interactions between conditional and unconditional conservatism. Under unconditional conservatism, the book value of net assets is understated due to predetermined aspects of the accounting process. Under conditional conservatism, book value is written down under sufficiently adverse circumstances, but not up under favorable circumstances. The specification of earnings provided by the model yields hypotheses about how unconditional conservatism and other factors preempt conditional conservatism and so affect the asymmetric response of earnings to positive and negative share returns, both current and lagged, documented by Basu (1995, “Conservatism and the Asymmetric Timeliness of Earnings.” Ph.D. dissertation, University of Rochester’ 1997, “The Conservatism Principle and the Asymmetric Timeliness of Earnings.” Journal of Accounting and Economics 24, 3–37).This revised version was published online in August 2005 with a corrected cover date.  相似文献

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown   总被引:4,自引:0,他引:4  
Theory suggests that economic instruments, such as pollution taxes or tradable permits, can provide more efficient technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing dramatic decreases in allowed pollution – the U.S. petroleum industry's phasedown of lead in gasoline. Using a duration model applied to a panel of refineries from 1971–1995, we find that the pattern of technology adoption is consistent with an economic response to market incentives, plant characteristics, and alternative policies. Importantly, evidence suggests that the tradable permit system used during the phasedown provided incentives for more efficient technology adoption decisions.  相似文献

Dividend Pricing Models and REITs   总被引:4,自引:0,他引:4  
Dividend pricing/present value models relate current stock prices to expectations of future dividends. In this study we apply the West and Campbell–Shiller tests of the dividend pricing relation to an index of real estate investment trusts (REITs). REITs provide a unique test of these models since, during our study period, REITs were mandated to pay out at least 95% of taxable income as dividends. While our results complement previous research which finds that the dividend pricing model cannot be rejected if share repurchase is included as part of dividends, our data contain a much less significant amount of share repurchase, so that our approach to the issue of the viability of dividend pricing models offers an alternative insight. Our research suggests that, for our REIT population, dividend pricing models cannot be rejected.  相似文献

This study investigates the potential for farmland to improve mixed-asset portfolio efficiency. Three major conclusions are drawn from the research. First, in a world with certainty, farmland can be shown to statistically improve mixed-asset portfolio efficiency. Second, with the introduction of uncertainty into the portfolio allocation model, investors can justify small or no allocations of farmland in a mixed-asset portfolio, although it appears that even with uncertainty prudent investors should evaluate the asset class. Third, with respect to farmland investment and geographic diversification, the results question the ability of an optimized mean–variance portfolio to provide substantial improvement in comparison to a naïve portfolio. The marginal improvement in portfolio efficiency of an optimized farmland portfolio versus a naïve farmland portfolio is not statistically significant.  相似文献

In the context of this article the author states that the present law situation is quite sufficient, in order to fight frauds within the insurance range effectively. In his personal view it is missing however at general consciousness that such frauds represent criminal injustice. In all other respects the author demands the attitude of the insurance industry to bring already detected criminal offences also to criminal pursuit.  相似文献

We study the short‐ and long‐term valuation effects of Swedish takeovers. Using a sample of 93 bidding firms that acquired 101 targets between 1980 and 1995, we find that diversifying acquisitions lead to a negative market reaction and deterioration of the operating performance of the bidder. Announcement and performance gains in each of the three years following the acquisition occur only when bidders expand their core rather than their peripheral lines of business. Our findings suggest that focused acquisitions lead to greater synergies and operating efficiencies than diversifying acquisitions. Intra‐group acquisitions, however, show that bidders do not realise significant gains whether they adopt diversifying or focusing investment strategies by purchasing firms controlled by the Wallenberg and SHB conglomerate groups. Intra‐group targets realize significant gains regardless bidder's investment strategy. Finally, the evidence does not support the view that intra‐conglomerate acquisitions are associated with expropriation of minority shareholders. However, they appear to enhance the control rights of large shareholders of the bidding firm.  相似文献
