We survey the methodological advances in DEA over the last 25 years and discuss the necessary conditions for a sound empirical application. We hope this survey will contribute to the further dissemination of DEA, the knowledge of its relative strengths and weaknesses, and the tools currently available for exploiting its full potential. Our main points are illustrated by the case of the DEA study used by the regulatory office of the Dutch electricity sector (Dienst Toezicht Elektriciteitswet; Dte) for setting price caps. 相似文献

Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless. 相似文献

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime. 相似文献

Without an international climate agreement, extraction of more natural gas could reduce emissions of CO2 as more clean natural gas may drive out dirty coal and oil. Using a computable equilibrium model for the Western European electricity and natural gas markets, we examine whether increased extraction of natural gas in Norway reduces global emissions of CO2. We find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in Norway. If instead the additional quantity is exported directly, total emissions increase both in the short run and in the long run. However, if modest CO2-taxes are imposed, increased extraction of natural gas will reduce CO2 emissions also when the additional natural gas is exported directed.earlier version of this paper was presented at the 25th Annual IAEE International Conference in Aberdeen June 2002. 相似文献

ABSTRACT Most literature on utility sustainability focuses on internal operations; this misses the role that utilities could play within a community. This study measures the impact of municipal ownership of water and electric utilities on the sustainability policymaking of local governments. I find that municipalities with government-owned water utilities adopt more sustainability measures than those with investor-owned service. Similarly, municipally-owned electric utilities have higher levels of energy sustainability in the community, but not in government operations. The utilities provide fiscal and technical capacity to municipalities. Interdepartmental coordination also strongly predicts sustainability policymaking. This study brings potential community benefits to the discussion of private investment in public service delivery. 相似文献

From 1994 to 2003, New Zealands corporatized electricity lines networks operated with no industry regulator, but under the spotlight of mandatory information disclosure. As a result there exists a large body of detailed, audited and publicly available accounting data on the financial performance of these businesses. Using that data, this paper finds that price-cost margins have widened substantially since deregulation. We estimate the extent to which light-handed regulation has allowed profits to exceed the levels which would have been acceptable under the old rate-of-return regulatory framework, and find that the answer is about $200 million per year, on an ongoing basis.We thank colleagues at Victoria University, and two anonymous referees for this journal, for constructive comments on this paper.

规制分权化、组织合谋与制度效率--基于中国电力行业的实证研究 总被引:13,自引:0,他引:13
产业组织理论中关于规制合谋的研究分为芝加哥学派和图卢兹学派,研究结果均表明,规制机构与被规制企业之间的合谋行为降低了规制效率.降低了社会福利水平。文章主要研究中国当前规制分权化背景下的地方规制机构与被规制企业之间的合谋问题,并且用计量方法对规制的效果进行了检验.结果表明规制分权化没有显著的正面效应,即规制低效率。因此,规制分权化产生的合谋导致了规制低效率.而解决问题的关键是机制设计。 相似文献

制度互补与电力市场化改革 总被引:3,自引:0,他引:3
我国电力改革选择了从发电环节的改革开始,经重组国家电力公司、实行厂网分离,到实行电价改革的渐进式策略。这一策略虽然因其速度缓慢、终端用户无法分享改革利益而备受批评,但它使社会付出了较低的“无序成本”。随着供求关系的缓解.电力产业应强化制度互补作用,尽快改变改革在发电、输电、配电、售电各个环节之间进展不平衡的状况,着力实现配电和售电分离。在售电环节引入竞争机制.探索与市场化改革相适应的监管体制和交易方式,解决电源结构不合理、电力发电输电配电效率低、负外部性等深层次问题,最终建立有效监管的电力市场.使市场在电力资源的配置上发挥更大作用。 相似文献
