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. Any remaining errors are entirely our responsibility.JEL classification: D21; K23; L11; L43; L51 相似文献

Recently economists have become interested in why people who face social dilemmas in the experimental lab use the seemingly incredible threat of punishment to deter free riding. Three theories with evolutionary microfoundations have been developed to explain punishment. We survey these theories and use behavioral data from surveys and experiments to show that the theory called social reciprocity in which people punish norm violators indiscriminately explains punishment best.JEL Classification:

本文旨在回答以下问题:(1)在中国城市劳动力市场中,职业流动性别差异以何种模式体现?(2)职业流动性别差异主要受哪些因素决定?文章使用第二次中国妇女社会地位调查数据,预测人力资本、家庭因素、社会资本、市场结构转型对男女职业流动的影响。实证结果表明:在经济转型期间,人力资本因素并不能完全解释我国职业流动的性别差异,而家庭特征、社会资本以及劳动力市场结构变动都对职业流动性别差异产生显著影响。 相似文献

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields
such as organizational science, management science and economics and have long recognized that classification offers an approach
for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities).
However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific
research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate
the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational
classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they
fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity.
This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational
classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms
and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics)
are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic
classification approach for inferring and representing the historical relationships underpinning organizational diversity.
This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently,
this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification
of organizational diversity. 相似文献

Tests of convergent validity and procedural invariance were used to investigate whether individuals lacking direct experience with a commodity can provide valid responses to contingent-valuation questions eliciting ex post use values. Convergent validity between samples with and without experience was shown to hold for dichotomous-choice responses, but not for open-ended responses. 相似文献

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions. 相似文献

我国生态环境保护和治理的财政政策选择 总被引:5,自引:0,他引:5
环境的公共产品性质和外部性,决定了它应该成为政府财政投资的重点。因而财政政策对环境保护和治理的影响极大。从总体上看,我国的财政政策在支持生态环境保护和治理中发挥了重要作用。但由于财政政策在设计上存在着缺陷,致使其在生态环境建设中的支持作用未能完全发挥。基于此,本文提出了完善我国生态环境可持续发展的财政政策建议。 相似文献
