Rather than the endogenous, tournament-type regulation based on mean costs proposed by Shleifer almost twenty years ago, regulators have opted for market designs based on exogenously determined efficiency comparisons reflected in fixed productivity adjustments. These productivity assessments are based only on estimates of technical efficiency improvements derived from estimated production frontiers. Utilities’ prices and potential profits are driven by this externally determined market. This paper examines the impacts on utility efficiency rankings from variations in peer group frontier regulation in Europe and Australia as well as in its use in the U.S. Despite the potential for distortions caused by long periods with non-market prices, these regulatory applications measure only technical efficiency, leaving moot the assessment of optimal input selection. We examine both technical and allocative efficiency variations among firms from the different cost specifications employed by regulators involving output, factor inputs, and costs. How are rankings impacted when only subsets of total costs (e.g., O&;M, not capital or system losses) are used to gauge efficiency? Does the use of partial measures of capital relying on physical specifications impact efficiency rankings? Are rankings affected when comparisons are made independently one input at a time? Is the efficiency frontier stable? Finally, we compare alternative yardstick measures to a simple ranking on relative (total) cost per unit. 相似文献

环境规制、技术创新与中国火电行业的效率提升 总被引:19,自引:0,他引:19
基于效率的视角,本文对2004年中国30个省(自治区、直辖市)火电行业的环境规制进行分析。首先利用三阶段DEA模型排除经营环境与统计噪音对中国火电行业效率的影响,然后从非规制、弱规制、强规制三个层次分析环境规制程度与中国火电行业效率的关系。实证结果表明,环境规制可以提升中国火电行业整体的效率水平,总体上存在技术创新激励效应,但并非适用各个地区。最后本文根据环境规制与技术效率的关系,将中国各地区火电行业的发展模式划分为内力驱动环境友好型、环境弱友好型和外力推动环境友好型三种,并给出各自适应的规制建议。 相似文献

基于产业链效率的煤电纵向规制模式研究 总被引:17,自引:0,他引:17
本文认为,我国煤电产业链受到内生的纵向外部性和外生的需求强波动性的影响.政府在对其制定规制政策时必须基于这两种特性。同时,在评价规制政策有效性时需要以产业链整体效率为基准。本文归纳了7种煤电纵向价格规制模式,并在此基础上提出了“基于产业链规制”的概念。我们认为,将对电价的规制延伸到对电煤价格的规制是现阶段我国煤电产业链价格规制的最优选择。这不仅可以解决煤炭纵向价格双轨制带来的矛盾,还有利于资源的有效利用。为确保规制延伸的有效性,本文还对相关辅助政策提出了建议。 相似文献

Until late 1986, municipalities played a major role in cable television regulation.Municipalities not only regulated pricing and quality decisions but also taxed cablesystems in the forms of in-kind and in-cash concessions. These activities appear tofit well with the concept of taxation-by-regulation, which concludes that consumerwelfare is reduced because of the rent seeking behavior of local politicians. At thesame time however, the notion of regulation-by-taxation is equally plausible. Thatis, politicians may use taxation as a means to regulate the activity of a monopoly bylimiting monopoly rents and improving consumer welfare. This article empiricallyseparates these two effects and investigates the implications for consumer welfare. 相似文献

价格规制合同设计中信息租金与配置效率的协调方式 总被引:4,自引:0,他引:4
网络产业所具有的自然垄断特性使政府规制成为必要,但在信息不对称的情况下,被规制企业所具备的信息优势使政府在设计规制合同时必须面对和解决逆向选择问题。本文在考虑了参与约束和激励约束的基础上,通过建立含有信息租金的社会福利最大化目标函数,分析了企业信息租金的存在形式及其与配置效率的冲突关系,并提出了政府如何在提高资源配置效率和减少企业信息租金之间进行选择的协调方式。 相似文献

Efficiency and Firm Ownership: Some New Evidence 总被引:1,自引:0,他引:1
The paper investigates the effect of state ownership on efficiency of firmsusing an econometric model that allows for the separation of technical from allocative efficiency in adynamic setting. The estimation results, based on a sample of international airlines, suggest that state ownershipis associated with lower technical and allocative efficiency. State ownership's effect on technical efficiencyis mainly a dynamic one – lowering the rate of cost decline, whereas its effect on allocativeefficiency is static – raising the level of costs. Thus lower technical, rather than allocative, efficiency isthe main reason for state-owned firms to be less efficient than their private counterparts. 相似文献

The well known Averch Johnson effect states thatrate-of-return regulation will induce costinefficient production. This paper examinesregulation induced inefficiency in broad set ofenvironments including arbitrary regulatorymechanisms, multiple outputs/inputs, uncertainty,time dynamics, price discrimination, and more. Ishow that the Averch Johnson effect appliesthroughout a wide variety of settings. Despite thegenerality of framework, my analysis is trulyelementary and does not rely on Kuhn–Tucker analysisor three dimensional graphics. I also provideresults and discussion which clarifies the limits toAverch and Johnson-like insights in practicalapplications. 相似文献

Implementation of incentive regulation intelecommunications requires the accurate measurementof the change in productivity. An approach isintroduced that not only provides a measure of thechange in productivity but also allows for adecomposition into two mutually exclusive andexhaustive components – changes in technicalefficiency over time and shifts in technology overtime. Using annual data on four output measures andsix input measures for the period 1988 to 1998 fornineteen individual local exchange carriers, theresults indicate that productivity increased by about5.0 percent per year. This growth is due primarily toinnovation rather than improvements in efficiency. Ofthe nineteen LECs in the sample, thirteen wereoperating efficiently throughout the entire 1988–1998period. Of the remaining six, two showed a slightimprovement in efficiency while the efficiency of fourdeclined. In the aggregate, however, there wasvirtually no change in efficiency. Finally, acomparison is made between two methods of estimatingthe change in productivity. The conventional growthaccounting approach yields a lower estimate of therate of change in productivity than does the Malmquistindex approach. The difference between theseestimates is interpreted as the lower bound of thebias associated with the conventional growthaccounting approach to measuring the growth inproductivity. 相似文献

This paper models a sequential merger formation game with endogenous efficiency gains in which every merger has to be submitted for approval to the Antitrust Authority (AA). Two different types of AA are studied: first, a myopic AA, which judges a given merger without considering that subsequent mergers may occur; and, second, a forward looking AA, which anticipates the ultimate market structure a given merger will lead to. By contrasting the decisions of these two types of AA, merger policy implications can be drawn. In particular, the efficiency offence argument does not find any justification under a forward looking AA. 相似文献

问责制、最优预防与健康和安全管制的经济分析 总被引:15,自引:0,他引:15
作为民主政治制度的问责制首先在我国健康和安全管制领域引入而引起社会的广泛关注。虽然通过对官员的问责以追求一个最低乃至于零的事故概率,是一个人本政府理念的体现,但在既定的技术和资源条件下,这一追求并非是最优的选择。从效率上说,一个社会从而政府管制的最优预防水平,是在边际预防成本等于边际预期事故成本这一点上。所以,虽然问责制对中国民主政治制度的建设具有重要意义,但在健康和安全管制领域它并非是一个有效的制度安排。 相似文献

文章结合分工理论、运输经济学理论以及交易费用理论分别从分工演进、生产性质、交易性质等3个视角对神华集团的煤炭产运销一体化运营模式进行了分析。认为,神华集团煤炭产运销一体化运营属于一种链网组织,在我国经济发展的现阶段,神华集团的链网组织是分工演进的必然结果,并且该组织形式有效降低了生产成本和交易费用。但是,神华集团链网组织与市场之间的边界需要通过权衡内部生产成本与交易费用之和与市场交易费用之间的差异来进行界定。 相似文献

The telecommunications industry has a great ripple effect on the overall national economy. However, there is no consensus about what is the optimal regulation policy for the telecommunications industry. Regulations on the telecommunications industry are different by region (i.e. United States, European Union and Asia). A number of studies have been conducted on comparative efficiency analysis for different policies that apply stochastic frontier analysis or data envelope analysis. However, these comparative studies are inappropriate because the production functions for each region are not identical. Thus, this paper addresses meta-frontier methodology, which can reflect differences in production functions. The results indicate that the United States has the highest meta-frontier efficiency in contrast to previous research findings. 相似文献
