This paper sets out to identify the impact of fuel prices on new car purchases, using exhaustive individual-level data of monthly registration of new private cars in France from 2003 to 2007. Detailed information on the car holder enables us to account for heterogeneous preferences across purchasers. We identify demand parameters through the large oil price fluctuations of this period. We find that the sensitivity of short-term demand with respect to fuel prices is generally low. Using these estimates, we assess the impact of a policy equalizing diesel and gasoline taxes, assuming that consumers react similarly to fuel price changes from tax and from oil price variations. Such a policy would slightly reduce the share of diesel in new cars purchases in the short-run (i.e. before supply side adjustments take place), without substantially changing the average fuel consumption or CO2 emission levels of new cars. Alternatively, a carbon tax (at 15 ¬/ton of CO2) could slightly decrease these emissions in the short-run.
本文利用2003年至2007年法国每月新私家车登记的详尽个人数据,试图确定燃油价格对新车购买的影响。关于车主的详细信息使我们能够解释购买者的异质偏好。我们通过这一时期油价的大幅波动来确定需求参数。我们发现,短期需求对燃料价格的敏感性一般较低。使用这些估计,我们评估了平衡柴油和汽油税政策的影响,假设消费者对税收和石油价格变化的燃料价格变化的反应相似。这样的政策将在短期内(即在供给侧调整发生之前)略微降低柴油在新车购买中的份额,而不会大幅改变新车的平均燃料消耗或二氧化碳排放水平。或者,征收碳税(每吨二氧化碳15欧元)可以在短期内略微减少这些排放。

The Impact of Short Term Exposure to Ambient Air Pollution on Cognitive Performance and Human Capital Formation 短期暴露于环境空气污染对认知表现和人力资本形成的影响

Cognitive performance is critical to productivity in many occupations and potentially linked to pollution exposure. We evaluate this potentially important relationship by estimating the effect of pollution exposure on standardized test scores among Israeli high school high-stakes tests (2000-2002). Since students take multiple exams on multiple days in the same location after each grade, we can adopt a fixed effects strategy estimating models with city, school, and student fixed effects. We focus on fine particulate matter (PM2.5) and carbon monoxide (CO), which are considered to be two of the most dangerous forms of air pollution. We find that while PM2.5 and CO levels are only weakly correlated with each other, both exhibit a robust negative relationship with test scores. We also find that PM2.5, which is thought to be particularly damaging for asthmatics, has a larger negative impact on groups with higher rates of asthma. For CO, which affects neurological functioning, the effect is more homogenous across demographic groups. Furthermore, we find that exposure to either pollutant is associated with a significant decline in the probability of not receiving a Bagrut certificate, which is required for college entrance in Israel. The results suggest that the gain from improving air quality may be underestimated by a narrow focus on health impacts. Insofar as air pollution may lead to reduced cognitive performance, the consequences of pollution may be relevant for a variety of everyday activities that require mental acuity. Moreover, by temporarily lowering the productivity of human capital, high pollution levels lead to allocative inefficiency as students with lower human capital are assigned a higher rank than their more qualified peers. This may lead to inefficient allocation of workers across occupations, and possibly a less productive workforce.
在许多职业中,认知表现对生产力至关重要,并可能与污染暴露有关。我们通过估计污染暴露对以色列高中高风险测试(2000-2002年)标准化考试成绩的影响来评估这种潜在的重要关系。由于学生在每个年级结束后的多天在同一地点参加多次考试,我们可以采用城市、学校和学生固定效应的固定效应策略估计模型。我们重点关注细颗粒物(PM2.5)和一氧化碳(CO),它们被认为是两种最危险的空气污染形式。我们发现,虽然PM2.5和CO水平之间的相关性很弱,但两者都与考试成绩呈显著的负相关关系。我们还发现,人们认为PM2.5对哮喘患者的危害特别大,但它对哮喘发病率较高的人群的负面影响更大。对于影响神经功能的一氧化碳,其影响在人口群体中更为均匀。此外,我们发现,暴露于任何一种污染物都与不获得巴鲁特证书的概率显著下降有关,巴鲁特证书是以色列大学入学所必需的。研究结果表明,仅仅关注健康影响可能会低估空气质量改善带来的好处。就空气污染可能导致认知能力下降而言,污染的后果可能与各种需要精神敏锐度的日常活动有关。此外,通过暂时降低人力资本的生产率,高污染水平导致分配效率低下,因为人力资本较低的学生被分配到比更合格的同龄人更高的级别。这可能导致工人在不同职业之间的分配效率低下,并可能导致生产力下降。

Regulatory Safeguards for Accountable Ecosystem Service Markets in Wetlands Development 湿地开发中负责任的生态系统服务市场的监管保障
Pub Date : 2014-07-10 DOI: 10.17161/1808.20261

The use of environmental markets creates the potential for achieving environmental protection goals more efficiently than traditional regulation is capable of doing. Past experience with emissions trading programs and other forms of environmental markets that operate in conjunction with traditional regulatory programs, however, illustrates the risks that accompany reliance on market-based strategies. In particular, participants in environmental regulatory markets have in some instances manipulated them to enhance private gain while undercutting public environmental objectives. Using the wetlands mitigation component of the federal Clean Water Act’s dredge and fill permit program as an example, this essay recommends that market-based environmental programs incorporate five different types of safeguards to promote the accountability of both market participants and the agencies supervising the operation of those programs. Reliance on financial safeguards, verifiable performance standards, transparency and public participation safeguards, oversight mechanisms such as monitoring and inspections, and rule of law safeguards can preserve opportunities for efficient achievement of environmental protection goals while reducing the risk that markets will be used to subvert those goals.
环境市场的使用创造了比传统监管更有效地实现环境保护目标的潜力。然而,过去排放交易计划和其他形式的环境市场与传统监管计划相结合的经验表明,依赖基于市场的战略会带来风险。特别是,环境管制市场的参与者在某些情况下操纵市场以增加私人利益,同时损害公共环境目标。本文以联邦《清洁水法》的疏浚和填土许可计划中的湿地缓解部分为例,建议以市场为基础的环境计划纳入五种不同类型的保障措施,以促进市场参与者和监督这些计划运作的机构的问责制。依靠财政保障、可核查的业绩标准、透明度和公众参与保障、监测和检查等监督机制以及法治保障,可以保留有效实现环境保护目标的机会,同时减少市场被用来破坏这些目标的风险。

Fiscal Decentralization, Environmental Accountability and the Provision of Environmental Public Goods in China: Evidence from 30 Provinces 中国财政分权、环境问责与环境公共产品供给:来自30个省份的证据

This paper uses panel regression model to analyze the relationship between fiscal decentralization and local environmental management based on data from 30 Chinese provinces for the period 2002 to 2010. We hypothesize that for China, enterprises account for the majority of local government tax revenue and, due to their mobility, exert leverage over local government decisions concerning environmental public goods. To correct this situation, China’s central government implemented an environmental accountability system that features two indexes, COD for water pollution and SO2 for air pollution, which are considered in evaluating local government officials’ job performance. We find that the degree of fiscal decentralization strongly correlates with local government accepting higher levels of pollution. This paper empirically verifies that local government officials are reacting to the accountability system as demonstrated by the modest increase of pollutants included in the accountability system in comparison to the drastic increase of excluded pollutants.
本文基于2002 - 2010年中国30个省份的数据,采用面板回归模型分析了财政分权与地方环境管理的关系。我们假设,在中国,企业占地方政府税收的大部分,并且由于其流动性,对地方政府有关环境公共产品的决策施加影响。为了纠正这种情况,中国中央政府实施了一项环境问责制度,其中包括两个指标,水污染的COD和空气污染的SO2,这两个指标被用于评估地方政府官员的工作绩效。我们发现,财政分权程度与地方政府接受更高的污染水平密切相关。本文实证验证了地方政府官员对问责制的反应,体现在问责制中纳入的污染物适度增加,而未纳入的污染物急剧增加。

Gujarat is a state located in the North-West coast of India. It is known locally as Jewel of the West. It has an area of 196,204 km2 (75,755 sq mi) with a coastline of 1,650 km (about 990 mile). As per the Government notification of Gujarat State, an area of 457.92 km2 of MNP & S includes 148.92 km2 of 42 small and big Islands with coral reefs and mangrove forests and 309 km2 intertidal areas along the coast. Coastal area is the most dynamic and productive ecosystems, industry and tourism (Xiaojun, 2008). The physicochemical qualities of sea water are very important and critical for the health biodiversity existing in entire Gulf of Kachchh. The analysis of physico-chemical and plankton in the present study has achieved some important findings. The obtained results highlight that there is a pronounced variation in most of the water quality parameters with variation in season and geographical location.

We analyse how market competition in a vertically differentiated polluting industry is affected by product variants that comply at different levels with "green" social norms. A green consumption behaviour is considered as a byword of good citizenship. Consumer preferences depend on a combination of hedonic quality and compliance with the norms. Assuming that the high hedonic quality variant complies less with the norms than the low hedonic quality one, we characterize the different equilibrium configurations, depending on the perceived intensity of such norms. Then, we focus on the role that institutions may have in using these norms to reduce pollution emissions.
我们分析了垂直差异化污染行业的市场竞争如何受到不同程度上符合“绿色”社会规范的产品变体的影响。绿色消费行为被认为是良好公民的代名词。消费者的偏好取决于享乐品质和遵守规范的结合。假设高享乐质量变量比低享乐质量变量更不符合规范,我们根据这些规范的感知强度描述了不同的均衡配置。然后,我们关注机构在使用这些规范减少污染排放方面可能发挥的作用。

INTRODUCTIONThis paper examines a number of US chemical industry incidents and their effect on equity prices of the incident company. Furthermore, this paper then examines the contagion effect of this incident on direct competitors.METHODEvent study methodology is used to assess the impact of chemical incidents on both incident and competitor companies.RESULTSThis paper finds that the incident company experiences deeper negative abnormal returns as the number of injuries and fatalities as a result of the incident increases. The equity value of the competitor companies suffer substantial losses stemming from contagion effects when disasters that occur cause ten or more injuries and fatalities, but benefit from the incident through increasing equity value when the level of injury and fatality is minor.CONCLUSIONSPresence of contagion suggests collective action may reduce value destruction brought about by safety incidents that result in significant injury or loss of life.PRACTICAL APPLICATIONSThis research can be used as a resource to promote and justify the cost of safety mechanisms within the chemical industry, as incidents have been shown to negatively affect the equity value of the not just the incident company, but also their direct competitors.
本文考察了美国化工行业的一些事件及其对事件公司股价的影响。此外,本文还考察了这一事件对直接竞争对手的传染效应。方法采用事件研究方法来评估化学品事故对事故和竞争对手公司的影响。结果随着事故伤亡人数的增加,事故公司的负异常收益越深。当灾难造成10人或以上伤亡时,竞争对手公司的股权价值因传染效应而遭受重大损失,但当伤亡程度较轻时,竞争对手公司的股权价值通过增加而受益。结论传染性的存在表明,集体行动可以减少因安全事故造成的重大人身伤害或生命损失所带来的价值破坏。实际应用本研究可以作为一种资源来促进和证明化学工业内安全机制的成本,因为事件已被证明不仅对事件公司的股权价值产生负面影响,而且对其直接竞争对手的股权价值也产生负面影响。

A Bi-Objective Model for the Used Oil Location-Routing Problem 废油定位-路径问题的双目标模型
Pub Date : 2014-04-18 DOI: 10.2139/ssrn.2460366
Jiahong Zhao, V. Verter
A staggering amount of used oils (e.g., 1.4 billion gallons in the U.S.) are generated annually as part of our industrial lifestyle. These are harmful to the population and environment in the vicinity of the transport routes as well as the storage, treatment and disposal facilities. In this paper, we provide an analytical framework to simultaneously answer the following questions: Where should the used oil storage, treatment and disposal facilities be located? What are the most appropriate capacity levels for these facilities? Which routes should be used among the different echelons of facilities in the used oil collection network? Focusing on the hazardous ingredients of used oils that are airborne on release, we propose an environmental risk measure by incorporating the Gaussian plume model in the box model. We present a bi-objective model for the location-routing problem so as to minimize the total environmental risk and the total cost. We use a modified weighted goal programming approach, which proved to be computationally efficient through a wide range of tests. The application of the proposed analytical framework in Chongqing of Southwest China provided interesting managerial insights.
作为我们工业生活方式的一部分,每年产生的废油数量惊人(例如,美国有14亿加仑)。这些都对运输路线以及储存、处理和处置设施附近的人口和环境有害。在本文中,我们提供了一个分析框架来同时回答以下问题:废油的储存、处理和处置设施应该设在哪里?这些设施最合适的容量水平是多少?废油收集网络中不同层次的设施应采用哪些路线?针对废油释放过程中经空气传播的有害成分,提出了一种将高斯羽流模型纳入盒模型的环境风险度量方法。为了使总环境风险和总成本最小化,我们提出了一个定位路径问题的双目标模型。我们使用了一种改进的加权目标规划方法,通过广泛的测试证明了该方法的计算效率。本文提出的分析框架在重庆的应用提供了有趣的管理见解。

The application of the proposed analytical framework in Chongqing of Southwest China provided interesting managerial insights.","PeriodicalId":340493,"journal":{"name":"Pollution eJournal","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128982097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Widespread public support exists for the provision of natural amenities, such as lakes, rivers or wetlands, and for efforts to preserve these from agricultural pollution. Agri-environmental policies contribute to these efforts by encouraging farmers to adopt environmentally friendly practices within the vicinity of these ecosystems. A spatially targeted agri-environmental policy promotes natural amenities and may thereby affect household location decisions. The purpose of this paper is to investigate the extent of these impacts on the spatial urban structure. We extend a monocentric city model to include farmers’ responses to an agri-environmental policy. Our main findings are that the implementation of a spatially targeted agrienvironmental policy may lead to some additional urban development, which could conflict with the aim of the policy.

公众普遍支持提供湖泊、河流或湿地等自然景观,并支持努力保护这些景观不受农业污染。农业环境政策通过鼓励农民在这些生态系统附近采取环境友好的做法来促进这些努力。有空间针对性的农业环境政策促进自然舒适,从而可能影响家庭选址决策。本文旨在探讨这些因素对城市空间结构的影响程度。我们扩展了单中心城市模型,以包括农民对农业环境政策的反应。我们的主要发现是,实施有空间针对性的农业环境政策可能会导致一些额外的城市发展,这可能与政策的目标相冲突。(这个摘要是从这个项目的另一个版本借来的。)

A Comparison between Shale Gas in China and Unconventional Fuel Development in the United States: Health, Water and Environmental Risks 中国页岩气开发与美国非常规燃料开发的比较:健康、水和环境风险
Pub Date : 2013-12-03 DOI: 10.2139/SSRN.2362774

China is appraised to have the world's largest exploitable reserves of shale gas, although several legal, regulatory, environmental and investment-related issues will likely restrain its scope. China's capacity to successfully face these hurdles and produce commercial shale gas will have a crucial impact on the regional gas market and on China’s energy mix, as Beijing strives to decrease reliance on imported oil and coal, while attempting to meet growing energy demand and maintain a certain level of resource autonomy. The development of the unconventional natural gas extractive industry will also endow China with further negotiating power to obtain more advantageous prices from Russia and future liquefied natural gas (LNG) suppliers. This paper, adopting a comparative perspective, underlines the trends learned from unconventional fuel development in the United States, emphasizing their potential application to the Chinese context in light of recently signed production-sharing contracts between qualified foreign investors and China. The wide range of regulatory and enforcement problems in this matter are accrued by an extremely limited liberalization of gas prices, lack of technological development, and political hurdles curbing the opening of resource extraction to private investors. These issues are exacerbated by concerns related to the risk of water pollution deriving from mismanaged drilling and fracturing, absence of adequate regulation framework and industry standards, entailing consequences on social stability and environmental degradation.
中国被认为拥有世界上最大的页岩气可开采储量,尽管一些法律、监管、环境和投资相关的问题可能会限制其范围。随着中国政府努力减少对进口石油和煤炭的依赖,同时试图满足不断增长的能源需求,并保持一定程度的资源自主,中国成功克服这些障碍、生产商业化页岩气的能力,将对地区天然气市场和中国的能源结构产生至关重要的影响。非常规天然气采掘业的发展也将赋予中国进一步的谈判能力,从俄罗斯和未来的液化天然气(LNG)供应商那里获得更有利的价格。本文采用比较的视角,强调了从美国非常规燃料发展中吸取的趋势,并根据合格的外国投资者与中国最近签署的产量分成合同,强调了这些趋势在中国的潜在应用。由于天然气价格自由化极为有限、缺乏技术发展和限制向私人投资者开放资源开采的政治障碍,在这个问题上产生了各种各样的管制和执行问题。由于钻井和压裂管理不善,缺乏适当的监管框架和行业标准,对社会稳定和环境退化造成了影响,因此人们对水污染风险的担忧加剧了这些问题。
