Social equity has become an important concern of the environmental movement over the past decade. The equity issue is analyzed here for practically all of the inactive hazardous waste disposal sites on the National Priorities List (NPL) regulated under the Comprehensive Response Compensation and Liability Act and its 1986 Superfund Amendments and Reauthorization Act (CERCLA/ SARA). Two dimensions of equity are emphasized, namely, site location relative to the location of minority populations and the distribution of cleanup plans or Records of Decision (ROD) across communities with NPL sites that have different socioeconomic characteristics. With respect to site location, the percentage of Blacks and Hispanics aggregated at the Census Place or MCD level in communities with NPL sites was greater than is typical nationwide (largely attributable to the concentration of minority populations in a few large urban areas with NPL sites). In contrast, the percentage of the population below the poverty line in communities with NPL sites largely matched that of the nation as a whole. With respect to site cleanup, communities with relatively higher percentages of racial minority populations have fewer cleanup plans (Records of Decision signed) than other communities with NPL sites. Whether a ROD exists is influenced by when the site was designated for the NPL: sites designated earlier (prior to the SARA amendments of 1986) are more likely to have RODs, and also less likely to have high proportions of racial minority populations than sites designated later. This implies that initially the designation process may have resulted in NPL sites being located disproportionately in minority areas, but this pattern seems to be reversing itself in more recently designated sites. As with any statistical analysis, these findings are findings of association and not causality. Thus, racial and ethnic disproportionalities with respect to inactive hazardous waste site location seem to be concentrated in a relatively few areas. Disproportionalities with respect to cleanup do exist, but appear to be more a function of the nature of the process of designation of NPL sites in the early 1980s rather than a result of actions connected with cleanup plans per se. Further investigations are needed at alternative geographic scales to discern the sensitivity of patterns of inequity to distance from the sites.  相似文献

This paper considers the estimation problem of structural models for which empirical restrictions are characterized by a fixed point constraint, such as structural dynamic discrete choice models or models of dynamic games. We analyze a local condition under which the nested pseudo likelihood (NPL) algorithm converges to a consistent estimator, and derive its convergence rate. We find that the NPL algorithm may not necessarily converge to a consistent estimator when the fixed point mapping does not have a local contraction property. To address the issue of divergence, we propose alternative sequential estimation procedures that can converge to a consistent estimator even when the NPL algorithm does not.  相似文献

We review the literature on recent changes to US employment relationships, focusing on the causes of those changes and their consequences for inequality. The US employment model has moved from a closed, internal system to one more open to external markets and institutional pressures. We describe the growth of short-term employment relationships, contingent work, outsourcing, and performance pay as well as the success of social identity movements in shaping employment benefits. In doing so, we address the role of organizations as sites of conflict within and between stakeholder groups, examining how struggles among stakeholders have contributed to reorganizing employment relationships. We also examine how these changes have affected inequality by (i) influencing the distribution of rewards within organizations (via changes in the determination of pay and benefits and in the allocation of workers to jobs) and (ii) altering, on a macro level, how rewards are distributed among different stakeholders. In closing, we identify areas where future work is urgently needed.  相似文献

International development agencies believe that by adopting institutional reforms based on the best practices that have proved effective elsewhere, so-called « developing countries » could take their places in the globalised economy. Based on a case study carried out on the implementation challenges of a decentralization project in Tunisia, I will argue by using an interpretive approach that this thesis is not sustained. This article shows that institutions cannot be reduced to their technical functions but that they are based on particular collective imaginaries that ground what is legitimate or not and structure the relationship of individuals to power and the meaning given to their actions. It encourages the consideration of cultural framework of meaning; these local cultural references structure the governance modalities of a society, understood in terms of the modalities of exercise of power in a given group (state, company, local authority, etc.). It advocates the necessity to move from a technic-prone approach in the implementation of institutional changes towards a socio-cultural approach that integrates the local expectations of what “good governance” should be and on which depends the legitimacy of institutions and their appropriation by local populations.  相似文献

考虑多种(非累积性和累积性)污染物对环境造成不同损害的前提下,首先基于Stackelberg博弈分析占主导的地方政府和跟随的工业企业各自的动态决策过程,确定工业企业的最优污染物排放量;随后运用最优控制理论构建两个相邻地区在非合作和合作博弈下关于跨界污染最优控制的博弈模型,分析地方政府的环境治理策略,包括最优的环境保护税、污染治理投资,探讨污染物存量的动态变化情况,并对此两种博弈结构进行了比较分析。理论及仿真分析表明:无论地区间是非合作还是合作博弈,工业企业的最优污染物排放量与其污染物减排比例的相关性不确定;每个地区的最优环境保护税与污染物减排比例呈正相关。但合作博弈下,每个地区均会考虑其非累积性污染物排放对其相邻地区造成的损害;每个地区均会增加污染治理投资;所有地区的总收益高于非合作博弈下,且高出部分(合作剩余)受累积性污染物的损害以及非累积性污染物对相邻地区损害的影响,但是与非累积性污染物对本地区的损害无关。  相似文献

本文从理论和实证两方面探讨了在地方政府竞争背景下,地方政府征税成本对货币发行与地区金融资产质量的影响.本文的研究发现由于从金融部门荻取金融资源这一外部性很强的方式成为地方政府间竞争的重要手段,其后果将使地方政府特别是难以获得充足税收收入的地方政府更倾向于通过干预金融部门为公共投资融资,这构成了引起地方金融资产质量下降,金融生态环境难以改善的重要制度性原因.本文认为只有继续深化金融改革,提高金融部门独立性,并且使地方政府财权和事权相适应,才可能正确引导地方政府积极性.使地方财政和金融两方面都步入良性循环的轨道.  相似文献

Understanding factors affecting decisions by people to protect themselves, or not, is critical to designing supportive communications. Here, threat, protective‐action, and stakeholder perceptions were evaluated for effects on mainland Americans’ behavioral intentions regarding Zika in April 2017, as postulated by the Protective Action Decision Model. Although all three perception types (including a novel resource sufficiency measure) affected intentions, these relationships varied widely depending upon the method used to measure adoption of actions (e.g., total count of all behaviors adopted vs. behavior‐specific analyses), the behaviors involved, and whether analysis focused on the full sample or only on people who had a reasonable opportunity to enact the behavior or who believed it relevant to their lives. There was a general contrast between mosquito control actions (removal of mosquito breeding areas and pesticide spraying) and travel‐related behaviors (avoiding travel to areas of local transmission of the virus, protecting oneself from mosquito bites after potential exposure, and practicing safe sex after potential exposure). Reported action or inaction during the 2016 mosquito season, and stages of behavior change, were both elicited in January–February 2017; both drove intentions in April 2017 for the upcoming season, although direct and indirect effects varied widely. Collectively these findings present theoretical, measurement, and practical implications for understanding, tracking, and promoting voluntary protective actions against hazards.  相似文献

As residents living in hazard-prone areas face on-going environmental threats, the actions they take to mitigate such risks are likely motivated by various factors. Whereas risk perception has been considered a key determinant of related behavioral responses, little is known about how risk mitigation actions influence subsequent perceived risk. In other words, do actions to prevent or mitigate risk reduce risk perception? This longitudinal study considers the dynamic relationships between risk perception and risk-mitigating behavior in the context of forest disturbance in north-central Colorado. Based on panel survey data collected in 2007 and 2018, the results provide a first look at changes in perceived forest risks as they relate to individual and community actions in response to an extensive mountain pine beetle outbreak. Analysis revealed that the perception of direct forest risks (forest fire and falling trees) increased, whereas indirect forest risk perception (concern on broader threats to local community) decreased across the two study phases. Higher individual or community activeness (level of actions) was associated with subsequent reductions in perceived forest fire risk, smaller increases in direct risk perception, and larger decreases in indirect risk perception. These findings contribute insights into the complex risk reappraisal process in forest hazard contexts, with direct implications for risk communication and management strategies.  相似文献

Public responses to nuclear technologies are often strongly negative. Events, such as accidents or evidence of unsafe conditions at nuclear facilities, receive extensive and dramatic coverage by the news media. These news stories affect public perceptions of nuclear risks and the geographic areas near nuclear facilities. One result of these perceptions, avoidance behavior, is a form of "technological stigma" that leads to losses in property values near nuclear facilities. The social amplification of risk is a conceptual framework that attempts to explain how stigma is created through media transmission of information about hazardous places and public perceptions and decisions. This paper examines stigma associated with the U.S. Department of Energy's Rocky Flats facility, a major production plant in the nation's nuclear weapons complex, located near Denver, Colorado. This study, based upon newspaper analyses and a survey of Denver area residents, finds that the social amplification theory provides a reasonable framework for understanding the events and public responses that took place in regard to Rocky Flats during a 6-year period, beginning with an FBI raid of the facility in 1989.  相似文献

There has been a documented, growing radicalism in the actions of some environmental public interest groups in recent years. In particular, groups pursuing the rights of animals and groups working for the environment have increased their militancy and action. What strikes these authors as curious is the total lack of debate and scholarly inquiry within the management profession over the ethics and tactics of these groups. The purpose of this analysis is to explore the ethics of public interest group activity, offer reasons for the lack of analysis by management researchers, and propose a modest research agenda for future investigations into the ethics of public interest groups.  相似文献

Industry leaders are setting the goal of sustainable products and services. The question is how this necessary but ambitious goal can be met. The author focuses on the environmental aspect of the expression “sustainable”. Strategies like eco-innovation, re-designs, and product improvements are discussed using examples such as the development of fuel cell vehicles, and the use of renewable and recycled materials. Major single actions (e.g. the development of new propulsion systems) as well as small improvements create a significant environmental benefit in total if “environmental economies of scale” are reached through mass production. Life cycle strategies, service instead of product strategies, as well as the link between “old” and “new” economy are described. The opportunities and challenges of these strategies for sustainable products are discussed. The author believes that it is necessary to look at a combination of all these strategies in order to reach the goal of sustainable products and services. In future, increasing numbers of life cycle stakeholders may have to be involved in these efforts, as their involvement is key to providing very efficient and effective additional positive effects.  相似文献

This paper studies the estimation of dynamic discrete games of incomplete information. Two main econometric issues appear in the estimation of these models: the indeterminacy problem associated with the existence of multiple equilibria and the computational burden in the solution of the game. We propose a class of pseudo maximum likelihood (PML) estimators that deals with these problems, and we study the asymptotic and finite sample properties of several estimators in this class. We first focus on two‐step PML estimators, which, although they are attractive for their computational simplicity, have some important limitations: they are seriously biased in small samples; they require consistent nonparametric estimators of players' choice probabilities in the first step, which are not always available; and they are asymptotically inefficient. Second, we show that a recursive extension of the two‐step PML, which we call nested pseudo likelihood (NPL), addresses those drawbacks at a relatively small additional computational cost. The NPL estimator is particularly useful in applications where consistent nonparametric estimates of choice probabilities either are not available or are very imprecise, e.g., models with permanent unobserved heterogeneity. Finally, we illustrate these methods in Monte Carlo experiments and in an empirical application to a model of firm entry and exit in oligopoly markets using Chilean data from several retail industries.  相似文献

The environmental impacts of industrial activity are an increasing concern amongst firms and their stakeholders. As a result, companies around the world have been exploring new tools to diminish the adverse impact of their activities on the environment. Eco-efficiency has played an essential role in this scenario, as companies are continuously seeking to produce more while utilizsing fewer resources and minimising adverse effects on the environment. The literature includes several initiatives to improve eco-efficiency and to reduce the environmental impact of manufacturing operations, but the use of production planning and control (PPC) activities to accomplish these goals has rarely been considered. Therefore, to contribute to the assessment of this issue, this paper proposes to integrate environmental concepts and actions as part of the PPC execution; therefore, they could also be applied to minimise environmental impacts, resulting in an increase in the eco-efficiency level of a company. The practical utilisation of the suggested procedure was confirmed using a case study where the procedure was successfully applied to a make-to-order firm, where a simplified version of a workload control (WLC) form of PPC was in use. As a result, incorporating environmental considerations into the WLC practices enabled the eco-efficiency level of the designated production area to increase by 42%, while the environmental impact of production was reduced by 13%.  相似文献

Like environmental management itself, the use of the Internet as a “green tool” has passed through various phases. Corporate responses to environmental pressures have varied from reactive and defensive to accomodative and even proactive. Similary, end-of-pipe solutions have started to give way to process and product-oriented environmental management. This increasing consideration of environmental issues by business has beenn reflected on the Internet in three different ways. Firstly, firms use websites as a means to communicate their environmental activities to a wider public. Some firms have done this much more extensively than others, sometimes in reaction to pressure exerted by environmentalists. Secondly, environmental organizations use the Internet to collect and exchange information, helping to facilitate the organization of world-wibe actions. In this way, firms can also learn about societal concerns and activities. Thirdly, and perhaps most conspicuosly for this purpose, the Internet has become a marketplace for consulting firms, government agencies, universities and non-governmental suggestions and the results of recent research.  相似文献

We review the concept of followership, with a specific focus on how followers actively influence leadership outcomes. We examine in particular research from four key areas: social identity perspectives on leadership, intergroup emotion theory, collective action, and reciprocal affect within leader–follower interactions. Our central proposition is that followers engage in actions, driven by both cognitive and affective-based processes, which affect leadership outcomes. Moreover, because leaders are part of the groups they lead and therefore embedded within the social context of a group, we propose that any action that affirms or threatens the salient group will trigger both cognitive and emotional responses from followers towards leaders. These include the extent to which a leader engages in actions that are perceived as (1) self-sacrificial, (2) procedurally fair, and (3) expressing emotions congruent with that of their group. We also propose that the extent to which followers translate their perceptions and emotions towards collective action towards their leaders will be moderated by individual-level group identification and group-level shared identity. To conclude, we highlight theoretical implications in light of these propositions and suggest areas for further research on followership.  相似文献

For years we have been hearing that US automobile manufacturers have been losing market share to their Japanese rivals who are reputed to make better quality vehicles. Most such reports are based on the initial quality surveys on new automobiles. In this paper we address two exploratory questions: (1) how does the quality of an automobile change with its age, and, (2) can firm level variables help explain differences quality. To answer these questions, we collected Consumer Reports’ reliability ratings on approximately 300 automobile models made by European, Japanese and US automotive firms during the 1998–2007; and approximately 240 models made by these firms over period of 2008–2015. For both periods we found that not only do automobiles made by Japanese firms have higher initial quality, but, as automobiles get older the difference in the product quality between Japanese versus European and US firms increases. We also found that the more generalist a European or US automobile firm, i.e., the wider is the firm׳s product offering in the marketplace, the lower its overall automobile quality during the 1998–2007 period. Conversely, Japanese generalist firms were found to have higher quality than specialist firms over the same period. The result is partly explained by the fact that Japanese firms have taken a different path to broadening their product variety – they have ensured a high level of quality of their initial offerings before entering newer market segments. The rate of reliability decline was found to be slower for all firms, and the differences in reliability across the 3 groups of firms were much less pronounced during the 2008–2015 period. This improvement may be as result of restructuring done by US automobile firms.  相似文献

Economists have traditionally viewed the behavioral response to risk as continuous and proportional. In contrast, psychologists have often contended that people have little control over their response to risk that is dichotomous, nonproportional, visceral, and fear based. In extreme cases, this automatic response results in the stigmatization of a product, technology, or choice, which seemingly cannot be eliminated or reduced. In resolving these contrasting perspectives, we review four recent studies that blend behavioral economics and psychology. Together, they provide evidence for a dual‐process decision model for risk that incorporates both reason and fear. They show consumers’ responses to perceived risk as a mix of proportional and dichotomous (safe/unsafe) responses that are relatively more continuous in situations where deliberation is possible, and more dichotomous in emotional or stressful circumstances. These findings reconcile mixed results in past studies, and, more importantly, the dual‐process model allows a clear definition of stigma, and suggests new ways to mitigate stigma and to help manage potentially damaging overreactions to it.  相似文献

A risk assessment was conducted to determine the likelihood of certain health risks resulting from exposure to soils and food crops contaminated with polychlorinated biphenyl (PCBs). PCBs have contaminated soils, river sediments, and air in the past as a result of industrial activities at a capacitor plant located in the City of Serpukhov, Russian Federation. This risk assessment and suggestions for remediation are designed to aid in decision-making efforts by a joint Russian-American research team developing a community, national, and international response to industrial contamination. Bobovnikova et al. (The Science of the Total Environment 139/140, 357-364, [1993]) have reported that PCBs are elevated in soils and sediments, breast milk, and locally grown foods in the Serpukhov area. Data from these and other investigators have been used in this risk assessment to calculate a potential cancer risk resulting from exposure to PCBs. Our assessment indicates that members of the local population may be at increased risk of cancer, and possibly other adverse health effects, as a result of PCB contamination of their environment. Because previously unassessed environmental contamination is a common problem in the former Soviet Republics, as well as many other areas of the world, we believe this type of evaluation, using known methods, can serve as a model for assessment efforts in other parts of the globe and result in remediative efforts in regions constrained by faltering economies.  相似文献
