The Application of Mathematical Programming Approaches to Estimating Container Port Production Efficiency 总被引:1,自引:0,他引:1
Kevin?CullinaneEmail author Dong-Wook?Song Tengfei?Wang 《Journal of Productivity Analysis》2005,24(1):73-92
Container terminal production is both an important and complicated element in the contemporary global economy. This paper aims to evaluate the efficiency of the world’s most important container ports and terminals using the two alternative techniques of Data Envelopment Analysis (DEA) and the Free Disposal Hull (FDH) model. The results give an insight into the current efficiency ranking of the world’s major container ports and terminals. They also confirm expectations that the available mathematical programming methodologies lead to different results and that appropriate variable definition of input and output factors is a crucial element in meaningful applications of DEA and FDH. It is also concluded that the availability of panel data, rather than cross-sectional data would greatly improve the validity of the efficiency estimates derived from all the mathematical programming techniques applied.JEL Classification:C61, D24, E23, L23, L25, L92 相似文献

We survey managers of Nasdaq firms that consistently pay cash dividends to determine their views about dividend policy, the
relationship between dividend policy and value, and four common explanations for paying dividends. The evidence shows that
managers stress the importance of maintaining dividend continuity and widely agree that changes in dividends affect firm value.
Managers give the strongest support to a signaling explanation for paying dividends, weak to little support for the tax-preference
and agency cost explanations, and no support to the bird-in-the-hand explanation. The study provides new evidence about how
managers view dividend life cycles and residual dividend policy.

Let X (r, n, m, k), 1 r n, denote generalized order statistics based on an absolutely continuous distribution function F. We characterize all distribution functions F for which the following linearity of regression holds
E(X(r+l,n,m,k) | X(r,n,m,k))=aX(r,n,m,k)+b.We show that only exponential, Pareto and power distributions satisfy this equation. Using this result one can obtain characterizations of exponential, Pareto and power distributions in terms of sequential order statistics, Pfeifers records and progressive type II censored order statistics.

《卓越绩效评价准则》国家标准(GB/T 19580—2004)参照国外质量奖评价准则、结合我国质量管理的实际情况和需要,同样把“领导”列为评价要求的第一部分,足见领导在组织创造卓越绩效过程中的重要位置和核心作用。显然,充分认识和把握领导及其领导力的作用,是组织贯彻实施《卓越绩效评价准则》的前提条件。 相似文献

中国城市中的三种贫困类型 总被引:32,自引:1,他引:32
我们课题组在 1 999年进行了一次覆盖六省市的住户调查。本文利用这次调查数据对中国城市贫困的性质和特点进行了考察。通过综合考虑收入标准和消费标准 ,我们把中国城镇贫困分为三种类型 ,即持久性贫困、暂时性性贫困和选择性贫困。在贫困人口中 ,有一大部分是属于选择性贫困 ,即他们的收入高于贫困线而消费低于贫困线。我们对贫困户的消费函数进行了估计 ,其结果显示以下几个因素对贫困状况产生重要的影响 :修匀收入的效应 ;人们防备外部环境不确定性的心理 ;人们为将来投资而进行储蓄的行为 ;家庭对子女教育和医疗服务的特别需要。我们还对三种贫困类型进行了比较分析 ,从中发现预测的金融资产和预测的收入 ,以及教育和医疗的特殊需要都对不同类型的贫困户的消费行为起到重要的影响作用 相似文献

The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances are to be applauded, the practitioner is left with a confusing array of rationales and the sense that almost any discount rate can be justified. This paper draws together these different strands and provides a critical review of past and present contributions to this literature. In addition to this we highlight some of the problems with employing DDRs in the decision-making process, the most pressing of which may be time inconsistency. We clarify their practical implications, and potential pitfalls, of the more credible rationales and argue that some approaches popular in environmental economics literature are ill-conceived. Finally, we illustrate the impact of different approaches by examining global warming and nuclear power investment. This includes an application and extension of Newell and Pizer [‘Discounting the benefits of climate change mitigation : how much do uncertain rates increase valuations?’ Journal of Environmental Economics and Management 46 (2003) 52] to UK interest rate data. 相似文献

In this paper I analyze the impact of regulatory policy on prices and demand for mobile telecommunications services across the European Union. I estimate a reduced form model of the mobile industry using panel data for the EU countries from 1998 to 2002. Among others, I find the following effects: liberalization of fixed telephone lines has a negative impact on prices and a positive impact on the demand for mobile services, and the introduction of mobile number portability has a negative impact on prices.*I am grateful to Toker Doganoglu, Gerd Hansen, Eric Kodjo Ralph, Guido Friebel, participants at the 30th EARIE Conference 2003, the 2nd International Industrial Organization Conference 2004 and the 19th Annual Congress of the EEA 2004, and anonymous referees for valuable comments. I would like to acknowledge the generous financial support from the Volkswagen Stiftung and the Munich Graduate School of Economics which made this research possible.
