The paper considers the degree to which declining market power explains modifications in pricing behaviour observed since the late 1970s in the North American aluminium, copper, lead and zinc industries. More precisely, it relates those changes in pricing policies to the price elasticity of demand facing the dominant strategic group in each industry, the cost elasticity of supply and to the management's ability to coordinate or internalize conduct decisions. The results suggest that the firms in the copper and lead industries do not hold as a group any form of market power. In the case of the aluminum industry, a notable increase in the price elasticity of demand since the end of the 1970s, a sustained decrease in the concentration ratio and a rigid production process are weakening the presence of market power in that industry. The results are inconclusive in the case of the zinc industry since the determinants of market power move in opposite directions.  相似文献

During the past decade, Norway has become an important oil and gas producer. Annual production is six times national consumption. Development policies of the national government have been cautious, and future policies will probably follow a similar pattern. The government recently opened offshore areas poleward of 62°N latitude, a decision likely to have a significant impact on Norway's future as an oil producer. Norway maintains a tight reign on foreign oil company participation, domestic downstream processing of crude, oil company taxation and oil revenue investment within the national economy. Norway's large inflow of oil-related capital investments and production revenues have contributed to significant inflation and to changes in local labour supplies. Norway has always used its petroleum industry to further the country's overall development goals, a policy that will continue in the years ahead.  相似文献

Summary The author presents the results of a pilot study which explored the voluntary support given by seven Pittsburgh multinationals to environmental goals and objectives through their foundations and operations. While much of the information is national in scope, the findings have international significance. Fundamental common key factors and patterns were identified which already have and will continue to guide most corporate international environmental activities. As interest grows in developing cooperative undertakings with the corporate community, it is important for environmental organizations, government, and academia to understand these patterns. Based on the findings and on suggestions by corporate representatives, recommendations are given as to how support of the goal of creating sustainable societies by the corporate and environmental communities can be improved and increased. Dr Langord's interest in urban and environmental policies range from issues dealing with coastal zone and floodplain management to urban waterfront re-vitalization and environmental aesthetics. Most recently she is studying the role of industry in helping to meet critical resource and environmental needs. She is exploring new patterns of cooperation with government, industry and environmental organizations. Currently Director of the International Environment Program, Center for International Studies, University of Pittsburgh, Dr Langord has held a number of academic positions, served as a resource policy analyst for the US Department of Interior, and has acted as a consultant to government and industry.  相似文献

Nonfuels minerals policy in the USA flows from the differential and unique reactions of these industries to general economic policies in the areas of taxation, land use, environment, and international trade. To search for nonfuels minerals policy as direct statements by the US government on nonfuels minerals is futile. Nevertheless, the industries are unique in many characteristics, and the application of these general policies to the minerals industries creates unique situations. This uniqueness has been recognized by a virtually constant policy review over the past 10 years. The current effort is just beginning, and to prejudge now the outcome of this discussion is premature. However, it is not premature to argue that because of the uniqueness of these industries, it may be expected that their problems will be receiving public attention for many years to come.  相似文献

The objective of this paper is to test the hypothesis that cyclical metal mining activity is more stable when multi-metal products are produced. A theoretical short-run supply curve for a metal is developed showing by-product, co-product, and main product behaviour. This curve is used to illustrate co-product pricing trends that are indicative of different cyclical behaviour patterns. The non-parametrical sign test is used to test co-product price trends for the US metal mining industry. The results indicate that multi-metal production stabilizes the mining industry in the short run but not in the long run.  相似文献

Following the intent of the National Environmental Policy Act of 1969, many states have adopted policies and procedures directing state agencies and local government units to evaluate the potential environmental impacts of development projects prior to their undertaking. In contrast to a rich literature on federal requirements, current understanding of state environmental review is narrowly focused and outdated. This paper seeks to provide information on the landscape of state environmental review policy frameworks. The paper identifies 37 states with formal environmental review requirements through a document review of state statutes, administrative rules and agency-prepared materials, and confirms this finding through a survey of state administrators. A two-tier classification is used to distinguish states based on the approach taken to address environmental review needs and the scope and depth of relevant policies and procedures implemented. This paper also provides a discussion of policy and programme attributes that may contribute to effective practice, and of the potential for adopting relevant legislation in states where environmental review is currently lacking.  相似文献

This study explores the potential for societies to create more green jobs for the disadvantaged. The research questions are related to how policy instruments can support green jobs and how green jobs can support the disadvantaged. These questions are asked in the context of the province of British Columbia in Canada, with implications for the global economy. Findings indicate that green jobs policies have direct and indirect effects on the growth of sustainable industries at a municipal level. Furthermore, in BC policy, green jobs are unmistakably connected to the government perception of green growth. Finally, the preferred pathway for policy implementation appears to involve local municipalities that apply for funding for projects that can potentially connect local actors and include the disadvantaged. Several policies accomplish the inclusion of the disadvantaged. The first section of this paper provides the BC provincial context on green jobs. The second section describes and analyzes a sample of thirteen BC policy instruments, as well as concurrent labor market policy activities for their inclusion of the disadvantaged. The third section posits a provisional policy framework for training and hiring more inclusively for green jobs. The fourth section offers six recommendations to bolster green jobs for all at a national and international level.  相似文献

Changes in material use, energy use and emissions profiles of industry are the result of complex interrelationships among a multitude of technological and economic drivers. To better understand and guide such changes requires that attention is paid to the time-varying consequences that technology and economic influences have on an industry's choice of inputs and its associated (desired and undesired) outputs. This paper lays out an approach to improving our understanding of the dynamics of large industrial systems. The approach combines engineering and econometric analysis with a detailed representation of an industry's capital stock structure. A transparent dynamic computer modeling approach is chosen to integrate information from these analyses in ways that foster participation of stakeholders from industry and government agencies in all stages of the modeling process-from problem definition and determination of system boundaries to generation of scenarios and interpretation of results. Three case studies of industrial energy use in the USA are presented-one each for the iron and steel, pulp and paper, and ethylene industry. Dynamic models of these industries are described and then used to investigate alternative carbon emissions and investment-led policies. A comparison of results clearly points towards two key issues: the need for industry specific policy approaches in order to effectively influence industrial energy use, fuel mix and carbon emissions, and the need for longer time horizons than have typically been chosen for the analysis of industrial responses to climate change policies.  相似文献

This study investigates how environmental strategies change over time. We submit evidence from the US steel industry that firms have modified their strategies over time. We offer that US industry passed through three stages--cost minimization, cost-effective compliance, and beneficial environmental controls. We compare typologies of environmental strategies and choose that of C. Oliver as the most appropriate. We investigate how environmental strategies in the steel industry changed over time a 4-year period. We offer that a further understanding of Oliver's strategies may increase understanding of the relationship between business and government on environmental issues. One over-arching problem in our field is the need to adequately operationalize how firms change strategies and pass through different stages. We hope that our study will help future researchers and practitioners better articulate the concepts of environmental strategies over time. Our study focused on the steel industry in the United States. We chose the US steel industry as one of the major environmental actors in the United States. The United States Environmental Protection Agency ranks the iron and steel industry as the largest industrial source of toxic environmental contamination. We encourage researchers to evaluate and test our methodology and findings in other contexts--both in other nations and different industries.  相似文献

Bolivia is a country of great mineral wealth with known reserves estimated to be worth over US$7 billion. Despite this great potential wealth, in the early 1980s the mining industry of Bolivia found itself in a crisis characterized by excessive state intervention in the industry, a financially troubled state mining company, large areas of the country off-limits to mineral development, an irrational tax system which discouraged mining and labour unrest. To deal with these problems, the government decided to restructure the mining industry so as to encourage private participation. This paper describes the policies introduced to revitalize the mining industry as well as projections of what the future benefits would be to the country if those policies are successful in achieving their objectives.  相似文献

This paper discusses the development impact of mining and mineral processing on the regions in which they are located. The discussion is organized so as to be of relevance for policy formulation in resource-rich developing countries which consider the exploitation of their mineral wealth. The hypothesis is that mining technology, interpreted in a broad sense, has undergone a profound change since 1900. In consequence, experiences of mineralbased regional development in the industrialized countries around the turn of the century are of little relevance to the Third World in the 1980s. Contemporary mineral ventures have very weak regional development repercussions in the absence of forceful policies specifically directed towards the regional development goal.  相似文献

This paper describes new environmental policies and expanded administrative agencies which in recent years have been adopted by many governments faced with a continuing decline in the quality of their environments. In a number of developed and developing countries, devising a far reaching environmental policy for sustainable development of the natural resources sector is a national priority. Specific environmental policies may be classified according to objectives, timeframe, mechanisms for implementation, whether or not they are binding, and the nature of sanction. This paper provides some generalizations about certain features common to most environmental policies. In the first section an examination is made of some of the most pressing problems which environmental policies relating to natural resources seek to address. The second section discusses environmental policies themselves. The third section, which makes up the main body of the paper, assesses the strengths and weaknesses of a variety of mechanisms available for implementing environmental policies to promote sustainable development in the natural resources sector.  相似文献

The regulatory structures underlying United States and European Union policies regarding genetically modified (GM) food and crops are fundamentally different. The US regulates GM foods and crops as end products, applying roughly the same regulatory framework that it does to non GM foods or crops. The EU, on the other hand, regulates products of agricultural biotechnology as the result of a specific production process. Accordingly, it has developed a network of rules that regulate GM foods and crops specifically. As a result, US regulation of GM foods and crops is relatively permissive, whereas EU regulation is relatively restrictive. Why are genetically modified food policies in the United States and the European Union so strikingly different? In the light of the recent World Trade Organization dispute on agricultural biotechnology, it may seem that economic interests are the driving force behind policies. While they are certainly part of the picture, the issue is far more complex. This paper argues that three different elements help explain differences between US and EU GM food policies. First, an investigation of US and European policies of the 1970s and 1980s on recombinant DNA research and of events leading up to early GM food and crop regulation allows a deeper understanding of current policy. Second, scrutinizing underlying values and norms can uncover the beliefs that condition current GM food and crop policy. Third, an analysis of involved actors’ views and levels of success in influencing policy is essential to understanding US and EU policies.  相似文献

Many US municipalities are engaged in climate change mitigation planning or efforts to reduce their communities' greenhouse gas emissions. However, most have adopted very few policies to implement their climate change mitigation goals, and many others are not pursuing climate change mitigation at all. This study examines municipalities' approaches to energy and climate issues and identifies the “keys to success” that influence the extent to which they adopt climate change mitigation policies.

Prior researchers have characterised climate change mitigation efforts as an example of multi-level governance, in which policies are formulated through a variety of networks and interactions between government actors and civil society. I find that municipalities that engage community interests and coordinate with neighbouring jurisdictions in their energy and climate planning processes are far more likely to adopt meaningful policies and conclude that such multi-level governance approaches are actually critical to the success of climate change mitigation planning.  相似文献

This paper analyses the extent to which the new Reagan mineral policy will encourage increased US production, substitution, recycling and conservation, domestic stock-piling and diversification of foreign supplies. Major inadequacies of the mineral policy are the transfer of responsibility for research and development from the government to the unprepared private sector, the lack of emphasis on short-term research and development in mineral processing technology, and the lack of coordination between minerals policy and national security and foreign policy. However, overall the policy is a positive step towards reducing the current US minerals supply vulnerability.  相似文献
