How to implement emission trading is one question in the current negotiations on a new sulfur protocol in Europe. Whereas the current protocol stipulates a 30 percent uniform reduction, national emission ceilings included in the proposed new protocol imply differentiated reductions. In addition, emission and fuel standards are proposed. This paper examines the costs and environmental impacts of emission trading. Emission trading combined with regulations is a new element in the paper. Calculations using the RAINS (Regional Acidification INformation and Simulation) model suggest that overlaying emission trading on regulations not only reduces the cost savings but has beneficial impacts as well: ecosystem protection is not changed and significant decreases in environmental benefits for countries are largely avoided. Emission trading can also be used to decrease emissions and increase ecosystem protection. If combined with existing legislation, emission trading minimizes losses in expected environmental benefits for some countries, and most countries gain. However, the initial distribution of emission ceilings has to be used so that some countries are not confronted with higher costs. Trade-offs appear to exist between the use of emission trading to achieve cost savings on the one hand, and ecosystem protection and distributional equity on the other. 相似文献

The importance of evaluating a discipline system from an ethical perspective is considered. Disciplinary practices in contemporary organizations are frequently characterized by managers having to choose from among alternative courses of corrective action. Since the selected alternative may have serious consequences for the individuals involved, its rightness or wrongness is of concern. The pattern of these choices reflects the overall disciplinary practice of the organization, and is an issue that warrants attention from an ethical perspective. Basic schools of thought that influence contemporary discipline practices are discussed and suggestions are made for conducting an evaluation of the ethical nature of a discipline system. 相似文献

Realistically, organizational and/or system performance is dynamic and non-linear. However, in the efficiency literature, system performance is frequently evaluated considering linear combinations of the input/output variables and without explicitly taking into account the causes of efficiency behavior nor the dynamic behavior of systems. Policy decisions based on these results may be sub-optimized because the non-linear relationships among variables, causal relationships, and feedback mechanisms are ignored.This research takes the initial step of evaluating system performance in a dynamic environment, by relating the factors that effect system performance to the policies that govern it. To accomplish this, this paper extends the concepts of the static production axioms into a dynamic realm, where inputs are not instantaneously converted into outputs. The relationships of these new dynamic production axioms to the basic behaviors associated with system dynamics structures are explored. 相似文献

Probability theory in fuzzy sample spaces 总被引:2,自引:0,他引:2
This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement. The author would like to thank the participants of the 23rd Linz Seminar on Fuzzy Set Theory for the intensive discussion of the paper. Especially he is indebted to Professors Diamond and Höhle whose remarks have helped to get deeper insights into the subject. Additionally, the author is grateful to one anonymous referee for careful reading and valuable proposals which have led to an improvement of the first draft.This paper was presented at the 23rd Linz Seminar on Fuzzy Set Theory, Linz, Austria, February 5–9, 2002. 相似文献

We examine the statistical performance of inequality indices in the presence of extreme values in the data and show that these indices are very sensitive to the properties of the income distribution. Estimation and inference can be dramatically affected, especially when the tail of the income distribution is heavy, even when standard bootstrap methods are employed. However, use of appropriate semiparametric methods for modelling the upper tail can greatly improve the performance of even those inequality indices that are normally considered particularly sensitive to extreme values. 相似文献

整合产品服务系统——实现循环经济的新途径 总被引:1,自引:0,他引:1
整合产品服务系统(IPSS)是一种社会组织创新战略,通过将目前仅生产和销售有形产品的相互分离的工业生产与服务体系有机地整合,以比传统生产和消费模式更低的环境代价,有效满足顾客需求。作为对传统商业模式的革命性变革,整合产品服务系统是促进可持续发展和循环经济的有效手段和必由之路。本文讨论其产生的背景,给出其定义和理论框架,介绍其发展历程,以便为我国发展循环经济提供借鉴。 相似文献
