Allocating Tradable Permits on the Basis of Market Price to Achieve Cost Effectiveness

It is a well known result that distributional constraints can lead to an imperfectly competitive permit market where the emission target is no longer met at least cost. In this paper, we suggest an allocation rule for tradable permits which can handle this problem. If the permit allocation is dependent on the market price for permits, this allocation rule can achieve both cost effectiveness and meet specific requirements for cost distribution across agents.     

排污权交易的层级市场理论与价格研究

借鉴股票的发行、流通、监管程序,提出排污权交易的层级市场结构理论,并据此对排污权交易进行了系统的研究。研究表明,作为排污权交易一级市场（发行市场）的补充,规范有序的排污权交易二级市场（流通市场）对提高排污权交易的效率是必要的;考虑竞争替代的因素采用双方叫价博弈模型研究二级市场的价格问题;最后分析排污权交易中的政府监督及监管问题,认为中央政府和地方政府的双重代理人特性会使政府监督严重失灵,可替代的选择是引进地方政府代理人竞争,通过“社区监督”以强化“政府监督”。     

不同市场条件下的初始排污权免费分配方法的选择

要实施排污权交易制度，在理论和实践中首先要解决的一个关键问题是初始排污权的分配问题。因为在实践中以初始排污权的免费分配方式更具有操作性，所以亟待解决的是初始排污权免费分配方案的选择与制定。本文研究的是在不同的市场条件下分析、建立并选择适合的初始排污权免费分配的分配模型。

An Empirical Study on Corporate Governance and Market Valuation in China

This paper empirically studies the relationship between the governance mechanisms and the market valuation of publicly listed firms in China. The authors construct measures for corporate governance mechanisms and measures of market valuation for all publicly listed firms on the two stock markets in China by using data from the firm’s annual reports. They then investigate how the market-valuation variables are affected by the corporate governance variables while controlling for a number of factors commonly considered in market valuation analysis. A corporate governance index is also constructed to summarize the information contained in the corporate governance variables. The index is found to have statistically and economically significant effects on market valuation. The analysis indicates that investors pay a significant premium for well-governed firms in China, benefiting firms that improve their governance mechanisms.

Addressing Negative Willingness to Pay in Dichotomous Choice Contingent Valuation

This paper has four purposes. First, we outline the controversy surroundingthe issue of negative willingness to pay (WTP)in contingent valuation (CV) studies. Second,we use Monte Carlo simulation to examine theperformance of alternative distributionalassumptions in estimating WTP in the presenceof varying proportions of the populationholding negative WTP values. We focus ondichotomous choice CV (DC-CV), where negativeWTP values may be especially difficult todetect. Third, we extend the simulation toinvestigate the performance of the mixturemodels that have recently been proposed forhandling/identifying non-positive WTP values. Fourth, we extend the simulation to investigatethe performance of the nonparametric lowerbound Turnbull approach. Results indicate thatthe relative performance of the DC-CV modelingalternatives evaluated here, which assumepositive WTP, varies across the simulationsetting (e.g., proportion of negative WTP); butnone can be said to reasonably ``solve' theproblem ex post. This underscores theimportance of ex ante efforts to identify ifnegative WTP is likely to be prominent in agiven valuation setting. In such cases,appropriately handling negative WTP must beaddressed through ex ante survey design andmodeling choices that allow negative WTP.     

Combining Contingent Valuation and Choice Experiments. A Forestry Application in Spain

When many good variants are to be valued, like in several forest management programs which differ in the attribute levels, the Contingent Valuation Method may not be a practical option, given the cost and time involved to value each variant separately. There are at least three alternative procedures in such situations. One (i) is to apply an attribute based valuation method like a Choice Experiment (CE); another (ii) is to conduct a CVM and a CE exercise and estimate a joint model; a third one (iii) is to use the CVM estimates to value a base scenario, and then use the CE results to adjust the CVM estimates for any new different scenario. A numerical simulation and an empirical application to an afforestation program in Spain show that the latter is the procedure that yields closer values to the CVM estimations, followed by (ii).      

Taxesversus tradable discharge permits: A review in the light of the U.S. and European experience

The U.S. and West European environmental protection programs have incorporated different economic instruments for controlling pollution. The U.S. has made extensive use of tradable permits of several forms but has never used direct pollution taxes. The countries of the European Community have long used an array of pollution taxes but have never used tradable permits. A review and critique of these experiences and an analysis of the attributes of taxes and tradable permits seeks identify the strengths and weaknesses of each instrument and to provide guidelines for the successful implementation of each system.     

Using Choice Experiments to Value the Environment

This paper we outline the “choice experiment” approach to environmental valuation. This approach has its roots in Lancaster's characteristics theory of value, in random utility theory and in experimental design. We show how marginal values for the attributes of environmental assets, such as forests and rivers, can be estimated from pair-wise choices, as well as the value of the environmental asset as a whole. These choice pairs are designed so as to allow efficient statistical estimation of the underlying utility function, and to minimise required sample size. Choice experiments have important advantages over other environmental valuation methods, such as contingent valuation and travel cost-type models, although many design issues remain unresolved. Applications to environmental issues have so far been relatively limited. We illustrate the use of choice experiments with reference to a recent UK study on public preferences for alternative forest landscapes. This study allows us to perform a convergent validity test on the choice experiment estimates of willingness to pay.     

Environmental Valuation – To Use or Not to Use? A Comparative Study of the United States and Europe

Valuation methods have been used for five main purposes in environmental decision-making. Cost–benefit analysis (CBA) of projects, CBA of new regulations, natural resource damage assessment, environmental costing, and environmental accounting. The relatively lower importance attached to economic efficiency in environmental decision-making in most European countries compared to the U.S.A., both legally and in practice, might account for our general finding that there are very few valuation studies in Europe which have served as a decisive basis for environmental policy and regulations. However, with EU's goal to establish environmentally adjusted national accounts and to apply CBA to environmental policy and regulations, time seems ripe for an increased use of valuation techniques in Europe.     

Political Competition, Rent Seeking and the Choice of Environmental Policy Instruments

This paper investigates the impact of political lobbying on the choice of environmental policy instruments. It is argued that the prevalence of pollution emission standards over more efficient policy instruments may result from rent seeking behaviour. The model further predicts that when an emission standard is used to control pollution, rival political parties have an incentive to set the same standard. There is therefore a convergence of policies. Moreover, it is shown that emission taxes are more likely to be supported and proposed by political parties which represent environmental interest groups. This feature appears to accord with the observed support for environmental taxes by Green parties in Europe, Australia, New Zealand and elsewhere.

Self-Reporting and Private Enforcement in Environmental Regulation

Self-reporting of compliance status has become a common feature in the enforcement of environmental regulation. In this paper, I generalize existing models of enforcement with self-reporting to include the possibility of private enforcement of regulation through citizen suits. This allows me to identify an additional argument for the efficiency of self-reporting: it can increase the likelihood of a successful suit and thus facilitate private enforcement of regulation. Specifically, if self-reporting sufficiently increases the expected penalty for losing a citizen suit, if the costs of private enforcement are low, and if inspection costs are high enough relative to enforcement costs, self-reporting lowers expected regulatory and social costs by allowing the regulator to rely on private enforcement and decrease his enforcement efforts.

从当前危机看政府与市场的关系

在金融危机引致全球经济衰退的背景下,政府与市场的关系再一次成为讨论中的焦点问题,实际上,此次危机在很大程度上恰恰是政府对市场长期实行不当干预的结果,是不恰当的政府调控、政府干预,是市场运行被长期扭曲所造成的一切不良后果的总爆发,也是市场规律对这些后果最终所作出的强制平衡。因此,要正确地汲取危机的教训,最重要的应是反思政府调控方面存在的问题。     

Spatial Heterogeneity and the Choice of Instruments to Control Nonpoint Pollution

Because it is difficult to monitor emissions and to implement differentialtaxes and standards, uniform taxes and standards on agricultural chemicaluse are often proposed and used to control nonpoint-source pollution. Thisarticle analyzes the relative efficiency of these uniform instruments in thepresence of spatial heterogeneity. We show that the relative slopes of themarginal pollution cost and marginal profit of chemical use are only one ofthe factors that affect the relative efficiency. Other factors includecorrelation between marginal pollution costs and marginal profits and theslope and variability of marginal profits. In addition, a uniform tax mayresult in some farmers not using the chemical, and a uniform standard mayhave no effect on low-input land. We show empirically that the presence ofcorner solutions can reverse a conventional finding of tax or standardsuperiority based on the relative-slop rule.

Environmental policy, fuel prices and the switching to natural gas in Santiago, Chile

In this study I analyzed the role of environmental policies and energy cost savings on the pattern of switching to natural gas by stationary sources in Chile. According to the data most of the switching was induced by the lower cost of natural gas, although environmental policies played a small role and showed that sources were more sensitive to the cost of energy than to the environmental regulation.     

Environmental performance and returns to pollution abatement in China

Because of China's extremely rapid economic growth, the scale and seriousness of environmental problems is no longer in doubt. Whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management in China. This study analyzes how the performance of environmental management has changed over time using province level data for 1992-2003. Mixed results for environmental performance are shown using nonparametric estimation technique. We find that environmental performance index, abatement effort, and increasing returns to pollution abatement play important roles in determining the pollution level over the period of the study.     

Modelling the Non-market Environmental Costs and Benefits of Biodiversity Projects Using Contingent Valuation Data

CV studies rarely ask willingness to accept (WTA)questions, yet there are a range of environmentalprojects where there are likely to be potential losersas well as gainers. This paper presents evidence fromsix biodiversity projects that the inclusion ofcontingent compensation payments from thoserespondents who preferred the status quo cansubstantially reduce net project benefits, even whenthe proportion of losers is relatively small. Astatistical model for estimating the mean welfaremeasure from dichotomous choice data which allows forboth positive WTP, zero WTP, and WTA is described. Asmany environmental projects are likely to create bothgainers and losers, we recommend that CV analysts giveserious consideration to the collection and analysisof WTA data otherwise they risk generating biasedestimates of project benefits.
