"Liability and Environment" by Prof. Lucas Bergkamp analyzes the role of law, in particular civil liability, in controlling environmental pollution and risk. In modern environmental policy, liability has become a popular instrument. In this book, Prof. Bergkamp takes a fresh look at civil liability for environmental harm in an inter- and transnational context. Over the last decades, environmental regulations have mushroomed, and liability exposure for environmental harm has expanded significantly. At the international, EC, and national level further proposals for onerous strict environmental liability regimes are pending. The "polluter pays principle," which is an articulation of the "cost internalization" theory in the environmental area, is believed to justify such liability regimes. Applying an instrumental approach to law, Prof. Bergkamp aims to redefine the role of liability in the heavily regulated environmental area. He shows that in the regulatory state liability for environmental harm is not required by the polluter pays principle, is an uncertain and unreliable instrument for achieving prevention, results in an inefficient insurance scheme, and plays a dubious role in adjusting activity levels. Based on an analysis of the basic characteristics of alternative legal instruments, Prof. Bergkamp concludes that civil liability should play a more modest, limited role in an environmental law system dominated by public law. Where deterrence is the objective, objective fault liability can play a useful role as a sanction for violations of applicable standards. Where deterrence is not the objective, first party insurance or other public law regimes should be preferred over liability rules. In addition to civil liability of private parties, "Liability and Environment" discusses state liability under international, EC, and national law. Under international and EC law, breach of a primary obligation triggers a state's liability. Prof. Bergkamp argues that this rule should be applied also to liability of private parties. In the environmental area, a business' primary obligations are spelled out in detailed permit conditions, regulations and statutes. According to Prof. Bergkamp, only if a polluter breached a primary obligation, he should be liable for environmental harm. The system that Bergkamp advocates is an objective fault liability regime, in which public environmental law defines the standard of care for both government and industry. "In rebuilding our civil liability system, we should keep in mind that what we believe to be good for industry should be good for every one (or it is not good for anyone), and what is good for private parties should be good for the state (or it is not good for either). In rebuilding our civil liability system, the international law of state responsibility, which is unpolluted by risk spreading and activity level considerations, will guide us a long way."

卢卡斯·博格坎普教授的《责任与环境》分析了法律,特别是民事责任在控制环境污染和风险方面的作用。在现代环境政策中,责任已成为一种流行的工具。在这本书中,博格坎普教授对国际和跨国背景下环境损害的民事责任进行了全新的审视。在过去的几十年里,环境法规如雨后春笋般涌现,环境损害的责任暴露也显著扩大。在国际、欧共体和国家一级,关于繁重严格的环境责任制度的进一步建议正在等待中。“污染者付费原则”是环境领域“成本内部化”理论的一种表述,人们认为这种责任制度是合理的。博格坎普教授运用工具性的法律方法,旨在重新定义在严格监管的环境领域责任的作用。他表明,在监管国家对环境损害的责任不需要污染者支付原则,是实现预防的不确定和不可靠的工具,导致低效的保险计划,并在调整活动水平方面发挥可疑的作用。在分析替代性法律文书的基本特征的基础上,博格坎普教授得出结论认为,在公法主导的环境法体系中,民事责任应发挥较为温和和有限的作用。当威慑是目标时,客观过失责任可以作为对违反适用标准的制裁发挥有益的作用。如果威慑不是目的,第一方保险或其他公法制度应优先于责任规则。除了私人当事人的民事责任外,“责任与环境”还讨论了国际法、欧共体法和国内法下的国家责任。根据国际法和欧共体法,违反主要义务会引发国家的责任。博格坎普教授认为,这一规则也应适用于私人当事人的责任。在环境方面,企业的主要义务在详细的许可证条件、规章和法规中都有详细说明。博格坎普教授认为,只有当污染者违反了主要义务时,他才应对环境损害负责。博格坎普倡导的制度是客观过失责任制度,其中公共环境法规定了政府和行业的注意标准。“在重建我们的民事责任制度时,我们应该记住,我们认为对行业有利的东西应该对每个人都有利(或者对任何人都不利),对私人有利的东西应该对国家有利(或者对两者都不利)。”在重建我国的民事责任制度时,不受风险扩散和活动水平考虑影响的国家责任国际法将对我们有很长的指导作用。”“责任与环境”还涵盖了环境法的当前趋势和有争议的问题。例如,它分析了用来对股东施加责任的公司面纱穿透理论,以及对自然资源损害的责任和相关的评估和估值问题。毫无保留的讨论涉及诸如公司的“利益相关者”模型、可持续发展、风险评估和成本效益分析等主题。在对市场和政府失灵的概念进行评估之后,博格坎普教授提出了一种责任的违约-位移模型,其中责任本质上是对尚未监管领域的异常行为的“权宜之计”,是监管领域的一种制裁。这本书是针对先进的法律学生,学术学者和从业者。此外,政策和立法分析人士、立法者和政府官员也对此感兴趣。经济学家、哲学家、自由贸易和自由放任政策的支持者,以及环保主义者,都可能受益于这本书内容广泛、发人深省的观点。在书中提出的引人入胜的分析中,讨论了现代环境法和政策的许多当前问题。它是用简单、直接的语言写的,并尽量避免过多地使用法律术语和技术术语,所以它是任何读者都能理解的。

The Exchange Theory of Teenage Smoking and the Counterproductiveness of Moderate Regulation 青少年吸烟的交换理论与适度管制的反生产效应
Pub Date : 2001-04-01 DOI: 10.3386/W8262

About three-quarters of secondary schools are reluctant to vigorously enforce smoking bans due to various social pressures; ten percent of these schools do not have bans at all. Empirically, school-based smoking regulations appear, at best, ineffective at reducing teenage smoking and, more likely, may actually increase participation. Only schools which vigorously enforce bans have a lower smoking participation. In sum, teenage smoking participation appears to be non-monotonic in the level of enforcement. This paper develops an exchange model that explains this non-monotonic pattern. Smoking bans provide an exchange opportunity to less popular students. Less popular students who begin smoking validate the risk-taking behavior of existing teenage smokers who, in exchange, provide friendship to the newcomers. The enforcement itself becomes the glue which holds the group together. Teenage smoking bans, unless vigorously enforced, increase teenage smoking participation. An increase in self-esteem and other non-smoking related qualities, however, undermines the trading channel, which can help combat teenage smoking. Numerous pieces of empirical evidence, culled from the empirical social psychology literature, are consistent with all of the key predictions of the model.
由于各种社会压力,约四分之三的中学不愿大力执行禁烟令;这些学校中有10%根本没有禁令。从经验上看,以学校为基础的吸烟规定在减少青少年吸烟方面充其量是无效的,更有可能的是,实际上可能会增加青少年的吸烟率。只有那些严格执行禁令的学校才有较低的吸烟参与率。总而言之,青少年吸烟的参与在执法水平上似乎不是单调的。本文建立了一个交换模型来解释这种非单调模式。禁烟令为不那么受欢迎的学生提供了交换的机会。不太受欢迎的学生开始吸烟,证实了现有青少年吸烟者的冒险行为,作为交换,他们为新吸烟者提供了友谊。强制执行本身就成为将团体团结在一起的粘合剂。青少年禁烟令,除非大力执行,否则会增加青少年吸烟的参与。然而,自尊和其他不吸烟相关品质的增加破坏了交易渠道,这有助于打击青少年吸烟。从经验社会心理学文献中挑选出来的大量经验证据与该模型的所有关键预测一致。

Smoking Risks in Spain: Part Ii - Perceptions of Environmental Tobacco Smoke Externalities 吸烟风险在西班牙:第二部分-感知环境烟草烟雾外部性

Previous studies of smoking risk beliefs have focused almost exclusively on risks to the smoker. Using an original set of survey data from Spain, we examine the public's perceived risks from exposures to environmental tobacco smoke. The risk categories considered included lung cancer, heart disease, life expectancy loss, and low birth weight for children of smoking mothers. Risk beliefs were quite high, often dwarfing scientific estimates of the risk. The results are consistent with overestimation of risks from highly publicized, low probability events.
以前关于吸烟风险的研究几乎只关注对吸烟者的危害。使用一组来自西班牙的原始调查数据,我们研究了公众对暴露于环境烟草烟雾的感知风险。考虑的风险类别包括肺癌、心脏病、预期寿命下降和吸烟母亲的孩子出生体重过低。人们对风险的信念相当高,往往使对风险的科学估计相形见绌。研究结果与高度公开的低概率事件的风险高估是一致的。

Survey evidence for the Spanish population indicates that perceptions of lung cancer risk and life expectancy loss due to smoking are similar to estimates found in the United States. This paper also presents new evidence on the relative lung cancer risk for smokers, the perceived risk of lung disease for smokers, the heart disease risk for smokers, and the relative heart disease risk for smokers, all of which indicate substantial risk perceptions. Risk beliefs are particularly high for younger respondents, but are lower for better educated respondents.
西班牙人口的调查证据表明,对吸烟导致的肺癌风险和预期寿命损失的认识与美国的估计相似。本文还就吸烟者的相对肺癌风险、吸烟者的肺部疾病感知风险、吸烟者的心脏病风险和吸烟者的相对心脏病风险提出了新的证据,所有这些都表明吸烟者有实质性的风险认知。年轻受访者的风险信念特别高,但受过良好教育的受访者的风险信念较低。

Cost-Benefit Analysis and Relative Position 成本效益分析及相对定位
Pub Date : 2000-07-01 DOI: 10.2139/ssrn.237665
C. Sunstein, R. Frank
Current estimates of regulatory benefits are too low, and likely far too low, because they ignore a central point about valuation - namely, that people care not only about their absolute economic position, but also about their relative economic position. We show that where the government currently pegs the value of a statistical life at about $4 million, it ought to employ a value between $4.7 million and $7 million. A conservative reading of the relevant evidence suggests that when government agencies are unsure how to value regulatory benefits along a reasonable range, they should make choices toward or at the upper end. We begin by showing that the nation is nearing the end of a first-generation debate about whether to do cost-benefit analysis, with a mounting victory for advocates of the cost-benefit approach. The second-generation debate, now underway, involves important issues about how to value costs and benefits. Conventional estimates tell us the amount of income an individual, acting in isolation, would be willing sacrifice in return for, say, an increase in safety on the job. But these estimates rest on the implicit, undefended, and crucial assumption that people's well-being depends only on absolute income. This assumption is false. Considerable evidence suggests that relative income is also an important factor, suggesting that gains or losses in absolute income are of secondary importance unless they alter relative income. When a regulation requires all workers to purchase additional safety, each worker gives up the same amount of other goods, so no worker experiences a decline in relative living standards. The upshot is that an individual will value an across-the-board increase in safety much more highly than an increase in safety that he alone purchases. Regulatory decisions should be based on the former valuation rather than the latter. When the former valuation is used, dollar values should be increased substantially - conservatively, by 25 to 50 percent. Upward revisions of such magnitude clearly have important implications for a broad range of policy debates currently informed by cost-benefit analysis. We also show that an understanding of the importance of relative position suggests a rationale for various nonwaivable contractual terms in employment law, such as health care, parental leave, job security, and leisure. These terms, which have been attacked as welfare-reducing by many economists, give people important benefits with little or no impact on relative economic position. As with regulations that boost workplace safety, such contract terms may therefore be much more attractive when purchased by all than when purchased in isolation.
目前对监管收益的估计太低,而且可能太低,因为它们忽略了估值的一个中心点——即人们不仅关心自己的绝对经济地位,还关心自己的相对经济地位。我们表明,政府目前将统计生命的价值定为约400万美元,它应该雇用470万至700万美元之间的价值。对相关证据的保守解读表明,当政府机构不确定如何在合理范围内评估监管利益时,他们应该选择接近或接近上限。我们首先表明,美国关于是否进行成本效益分析的第一代辩论即将结束,成本效益方法的倡导者取得了越来越大的胜利。目前正在进行的第二代辩论涉及如何评估成本和收益的重要问题。传统的估计告诉我们,一个人在单独行动时,愿意牺牲多少收入来换取,比如说,工作安全的增加。但这些估计建立在一个隐含的、毫无根据的关键假设之上,即人们的幸福只取决于绝对收入。这种假设是错误的。相当多的证据表明,相对收入也是一个重要因素,这表明,除非绝对收入的增减改变了相对收入,否则它们是次要的。当一项法规要求所有工人购买额外的安全产品时,每个工人都放弃了等量的其他商品,因此没有工人经历相对生活水平的下降。结果是,一个人会更看重安全的全面提升,而不是他自己购买的安全提升。监管决定应基于前者的估值,而不是后者。当使用前一种估值时,美元价值应大幅增加——保守地说,应增加25%至50%。如此大幅度的向上修正显然对目前根据成本效益分析得出的广泛政策辩论具有重要影响。我们还表明,对相对地位重要性的理解表明了就业法中各种不可放弃的合同条款的基本原理,如医疗保健、育儿假、工作保障和休闲。这些被许多经济学家抨击为减少福利的术语,给人们带来了重要的好处,但对相对经济地位几乎没有影响。与促进工作场所安全的规定一样,这样的合同条款在所有人都购买时可能比单独购买时更具吸引力。

Environmental Liability and Technology Choice: A Duopolistic Analysis 环境责任与技术选择:一个双寡头分析
Pub Date : 2000-06-01 DOI: 10.2139/ssrn.235010
G. Mondello, M. Tidball
This paper focuses both on the competition process and the firms' liability in environmental protection and the demonstration is made by comparing two models of safety investment. The first one shows sensitive players to their environmental liability: they seek to minimize the technologies accident risk while the second one corresponds to a much more standard choice. The players' main preoccupation is about their market share even if they care about liability. Then, from a very simple duopolistic competition model with strict liability, we show, first, that the way the firms assess the environmental question is not neutral on their expected performances. Second, that the associated level of technology to the liability concern - i.e. a high level of care or a low one - have a different impact on profitability. Consequently, the competitors' general attitude, their beliefs and the institutional rules have strong effects on the environmental investment assessments. More precisely, the enforcing rule the players will adopt will play directly on the performance, not only of one firm, but on the whole set of industrial firms.
本文从竞争过程和企业在环境保护中的责任两个方面进行了研究,并通过比较两种安全投资模型进行了论证。第一个问题显示了敏感的参与者对他们的环境责任:他们寻求最小化技术事故风险,而第二个问题对应的是一个更标准的选择。玩家最关心的是他们的市场份额,即使他们关心责任。然后,从一个非常简单的具有严格责任的双寡头竞争模型中,我们首先表明,企业评估环境问题的方式对其预期绩效不是中性的。第二,与负债相关的技术水平——即高水平的护理或低水平的护理——对盈利能力有不同的影响。因此,竞争对手的总体态度、信念和制度规则对环境投资评价有很强的影响。更准确地说,参与者将采用的强制规则将直接影响企业的绩效,而不仅仅是一家企业的绩效,而是整个工业企业的绩效。

Property Value Impacts of an Environmental Disamenity 环境破坏对财产价值的影响
Pub Date : 2000-04-12 DOI: 10.2139/ssrn.290292

The purpose of this paper is to quantify the property value impacts of a change in environmental quality by using the hedonic price model. In particular, we focus on the impact of the presence of landfills on nearby residential real estate prices. We combine elements of an urban location choice and hedonic pricing model to estimate the effects of the presence of multiple environmental disamenities on residential real estate prices. We explicitly account for temporal effects by including housing transactions in areas with both open and closed landfills, and control for information effects. In addition, we treat property taxes and prices as being simultaneously determined. Our analysis suggests that closing landfills will not necessarily mitigate property value impacts.
本文的目的是通过使用享乐价格模型来量化环境质量变化对房地产价值的影响。我们特别关注垃圾填埋场的存在对附近住宅房地产价格的影响。我们结合城市区位选择和享乐定价模型的要素来估计多重环境不利因素对住宅房地产价格的影响。我们明确地考虑了时间效应,包括开放和封闭垃圾填埋场地区的住房交易,并控制了信息效应。此外,我们认为房产税和房价是同时确定的。我们的分析显示,关闭堆填区未必会减轻对物业价值的影响。

Our analysis suggests that closing landfills will not necessarily mitigate property value impacts.","PeriodicalId":168354,"journal":{"name":"Torts & Products Liability Law","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122407617","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}

Optimal Insurance Trading: Full Insurance with Unfair Prices and Asymmetric Information 最优保险交易:价格不公平和信息不对称的全额保险

In this paper we analyze trading behaviour in an economy with substantial individual heterogeneity and individual agent- specific endowment risks. We establish that markets can be made effectively complete with a very small number of assets. In particular, if full insurance contracts are available, agents will only actively trade in two assets: a mutual fund and a bond. We also establish that contrary to standard results in the insurance demand literature, agents' optimal insurance demand can include in equilibrium full insurance in the presence of insurance prices which are actuarially unfair and that this demand will be independent of the correlation of insurance payments and the payments of other assets. Finally, we introduce asymmetric information concerning agents' risks into the economy and we show that adding a restriction on agents' possible insurance trades rather than introduce additional inefficiencies serves to ensure the attainability of efficient net trades.
本文分析了具有显著个体异质性和个体代理人特定禀赋风险的经济中的交易行为。我们证明,市场可以用非常少的资产有效地完成。特别是,如果有完整的保险合同,代理人只会积极交易两种资产:共同基金和债券。我们还建立了与保险需求文献中的标准结果相反,在保险价格在精算上不公平的情况下,代理人的最优保险需求可以在均衡中包括全额保险,并且这种需求将独立于保险支付和其他资产支付的相关性。最后,我们在经济中引入了关于代理人风险的不对称信息,并证明了对代理人可能的保险交易进行限制,而不是引入额外的低效率,有助于确保有效净交易的实现。

Fairness and Two Fundamental Questions in the Tort Law of Accidents 公平与事故侵权法中的两个基本问题
Pub Date : 2000-01-01 DOI: 10.2139/ssrn.200778
Gregory C. Keating
This paper explores two central questions in the tort law of accidents--the choice between negligence and strict liability, and the level of reasonable precaution--from a fairness perspective. The first part of the paper develops the idea that liability rules are fair when they are ex ante and, over the long run, to the advantage of all those they affect, even those who fare worst under them. The second part of the paper investigates the choice between negligence and strict liability, taking into account two competing conceptions of fairness. One influential conception takes reciprocity or nonreciprocity of risk to be the master test of fairness, holding that accident costs are fairly distributed when the risks which give rise to accidents are fairly distributed. Another influential conception holds that the accident costs of risky activities should be spread among all those who benefit from the activity, ideally in proportion to their degree of benefit. This conception takes the distribution of harm--of the costs of accidents themselves--to be central. Part two of the paper argues that this second conception of fairness is preferable, and that it gives us good reason to believe that enterprise liability is prima facie fairer than negligence liability. Part three of the paper takes up the question of reasonable care, investigating the fair level of precaution. This part of the paper focuses particularly on the question of what fairness requires when an activity imposes a significant risk of serious injury. When an injury is serious--when the harm it does substantially impairs the pursuit of a normal life and when that harm cannot be repaired--fairness cannot be achieved by redistributing accident costs after the injury. Fairness must be achieved, if it can be achieved, by pitching the level of precaution at an appropriately high point ex ante. The paper argues that fairness requires pushing the level of precaution beyond the wealth maximizing point when substantial risks of serious injury are at issue. Fairness requires reducing such risks to the point where further reduction would threaten the activity that engenders them, the point where the long-run health of the activity would be jeopardized. The fourth and final section of the paper examines the connections between fairness and the forms of justice. Taking issue with the dominant position in contemporary tort theory, section four argues that justice (as fairness) in tort accident law is primarily a question of distributive justice, and only secondarily a matter of corrective justice.
本文从公平的角度探讨了事故侵权法中的两个核心问题——过失责任与严格责任的选择,以及合理预防的水平。本文的第一部分发展了这样一种观点,即责任规则在事前是公平的,从长远来看,对所有受其影响的人都有利,即使是那些在它们之下处境最差的人。论文的第二部分考察了过失责任与严格责任之间的选择,考虑了两种相互竞争的公平概念。一个有影响力的概念将风险的互惠或非互惠作为公平的主要检验标准,认为当引起事故的风险公平分配时,事故成本就公平分配。另一个有影响力的概念认为,风险活动的事故成本应该由所有从该活动中受益的人分摊,理想情况下是与他们的受益程度成比例。这种观念以危害的分配——事故本身的成本——为中心。论文的第二部分认为,第二种公平概念是更好的,它给了我们很好的理由相信,企业责任是初步公平比过失责任。论文的第三部分探讨了合理注意的问题,探讨了预防的公平程度。本文的这一部分特别关注的问题是,当一项活动造成严重伤害的重大风险时,公平要求是什么。当伤害很严重时——当伤害实质上损害了对正常生活的追求,当伤害无法修复时——在伤害发生后,通过重新分配事故成本是无法实现公平的。公平必须通过事先将预防水平设定在适当的高点来实现(如果可能的话)。本文认为,当存在严重伤害的重大风险时,公平要求将预防水平提高到财富最大化点之外。公平要求将这种风险减少到进一步减少将威胁到产生风险的活动的程度,减少到损害活动的长期健康的程度。论文的第四部分也是最后一部分考察了公平与正义形式之间的联系。第四部分对当代侵权理论的主导地位提出质疑,认为侵权事故法中的正义(作为公平)主要是分配正义问题,其次才是纠正正义问题。

The Value of Information in Efficient Risk Sharing Arrangements 信息在有效风险分担安排中的价值
Pub Date : 2000-01-01 DOI: 10.2139/ssrn.237644
Edward Schlee
A guard is disclosed for guarding the nip between a pair of rolls in a power roll mill to prevent the mill operator's fingers from being crushed between the rolls. The guard comprises an upstanding plate pivotally mounted transversely between the opposite side frame members of the rolling mill in front of the pair of rolls being guarded. The top of the guard is flat and is located adjacent and below the normal path for the infeed of a sheet of material being formed between the rolls in order that an operator's fingers which support the underside of the sheet will engage the guard and be prevented from entering the roll nip. The guard plate is depressibly supported at its opposite ends by a pair of upright tubular rocker arms which are pivoted at their base and are biased to a central neutral position. At least one microswitch is provided adjacent one of the rocker arms which is in electric circuit with an electric motor which drives the power rolls to turn the motor on and off. An actuator for the switch projects into contact with the rocker arm and is actuated by pivotal movement of the rocker arm to either side of its neutral position in order to open the microswitch and thus to stop the electric motor.
