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

Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important
paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line,
we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly
top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes
requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with
statistical rank based tests.

不同质量水平下的总质量成本研究 总被引:3,自引:0,他引:3
质量成本(COQ,Cost of Quality)是衡量提高质量活动的效果和效率的标准.COQ模型在质量成本研究中起着重要的作用.基于"6σ管理"中"持续改进"的思想和方法,用"kσ"作为质量水平(QL,Quality Level)的度量,笔者得到了不同质量水平下的动态总COQ模型.进而,还提供了不同质量水平下的总质量成本曲线. 相似文献

We offer a game-theoretic proof of Hamiltons rule for the spread of altruism. For a simple case of siblings, we show that the rule can be derived as the outcome of a one-shot prisoners dilemma game between siblings.JEL Classification:

An Austrian interpretation of the New Keynesian small menu cost model of the business cycle is proposed. Austrian and New
Keynesian business cycle theories share the feature that the cycle is generated by rigidities which prevent the economy from
adapting instantaneously to changing conditions. Austrian business cycle theory is capital-based, focusing on credit expansion
which artificially lowers interest rates and causes an investment boom and unsustainable business expansion. In contrast,
the New Keynesian small menu cost model of the business cycle is based on nominal rigidities which prevent markets from clearing.
Small menu costs introduce dichotomous behavior, where firms find it locally optimal to avoid instantaneous output price adjustments
in the face of the cost, but this local optimum results in economy-wide output and employment fluctuations which are much
greater in relative magnitude. The small menu cost model of the business cycle is extended and reinterpreted in light of Austrian
business cycle theory with heterogeneous, multiply-specific capital, thus providing a rigorous formalization of the Austrian
business cycle. The Austrian interpretation of this New Keynesian model fortuitously addresses several of its shortcomings.

It is recommended for economists to examine China’s Urban-Rural disparity from the perspective of transaction efficiency,
in that it can provide us with a systematic explanation to both the cases of different countries and development stages. China’s
Urban-Rural disparity is special and virtually a demonstration of its special transaction efficiency structure. Exploration
of China’s Urban-Rural disparity from such perspective indicates that, different from those in countries with a market economy,
China’s case involves many exogenous and contrived factors. Therefore, the solutions are to improve the whole transaction
efficiency in the economy, which includes eliminating its regionally unfavorable policies and institutions, and enforcing
more favorable and regionally balanced institutional reforms.

控制权性质影响税收敏感性吗?——基于企业劳动力需求的检验 总被引:9,自引:2,他引:9
西方学者研究表明企业所得税是劳动力需求的重要影响因素,这一理论在中国是否适用?中国大部分上市公司为国有控股企业,这一特殊的制度背景是否会影响企业所得税与劳动力需求的关系?本文基于2007年企业所得税改革这一外生政策变化,在检验西方企业所得税与劳动力需求关系的理论在中国是否适用的基础上,就不同控制权的性质是否会影响企业劳动力需求的税收敏感性进行了检验。研究发现企业所得税税率降低和"就业税盾"增加提高了企业劳动力需求,但这种税率和"就业税盾"的变化对国有控股企业劳动力需求变化的影响要显著小于非国有控股企业。这表明税收是影响企业劳动力需求的重要因素,但国有控制权使得这种税收敏感性变弱。本文的研究结果不仅丰富了相关领域的国际学术文献,而且对我国就业政策的制定具有政策含义。 相似文献

高校教育成本核算影响因素探析 总被引:1,自引:0,他引:1
高校教育成本核算既是满足高等教育不同投资主体对投资回报的客观需要,也是合理建立高等教育成本分担机制的必然选择,但因各种因素的制约,我国目前高校教育成本核算工作尚未有效的开展。本文在阐述教育成本相关理论及框架结构的基础上,从高校自身认识、宏观制度和微观技术性等方面,对影响高校教育成本核算的因素进行了分析,并提出了高校教育成本核算的措施。 相似文献
