Declining Discount Rates: The Long and the Short of it

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.

高等教育投资项目的财务评价

我国高等教育的高速发展对高等教育投资主体和资金来源多元化提出了新的要求。在这种情况下，对高等教育投资项目进行全面的财务评价就成为高等教育投资主体所关注的重要问题。鉴于高等教育投资项目在我国的发展才刚刚起步，相关的研究工作不多，因此，通过调查和对比分析，了解与高等教育相类似行业的投资项目评价，运用系统方法，提出和筛选高等教育投资项目的财务评价指标，初步形成高等教育投资项目财务评价指标体系，将对合理确定高等学校办学规模、正确评价高等教育投资项目提供理论依据和决策参考。     

On the cost-benefit of the regionalisation of the National Health Service

In this paper we analyse in formal terms the desirability of the regionalisation of a National Health Service. The policy consists of a devolution process, i.e. the increase in the health services provision to be decided by a region and financed by an increase in its revenues. The change is a marginal one, as it regards the part of supply of the health services exceeding a minimum standard, which for purposes of equity is maintained uniform in the national territory. As the central government is responsible for this component of the provision of health care (a federal “mandate”), the level of the said component is chosen by this authority and financed by federal taxation. Moreover, the government also applies an equalisation scheme based on the difference between a standard level of tax revenues and the revenues which the region is deemed able to raise for this purpose. Within the theoretical context of welfare improving reforms with distortionary taxation, we derive two conditions which focus on the regional, as well as the social, convenience of regionalisation.

浅析我国征地制度中"公共利益"界定与征地范围划分问题

在我国,土地征用权的法律规定主要来自《宪法》、《土地管理法》和《城市房地产管理法》。我国宪法,虽然赋予国家征用土地的权利,却没有为这种权利的行使划定明确的范围、界限、方式和程序;现行法律中关于土地征用权的规定互相矛盾,从而导致土地征用权的滥用,同时还存在对农民的补偿和安置不到位等问题。因此迫切需要完善土地征用制度,明确界定“公共利益”的范围,文章就此问题进行了初探,并提出了完善征地制度的建议。
