What are the implications of primary mineral constraints for the energy transition? Low-carbon energy production uses green capital, which requires primary minerals. We build on the seminal framework for the transition from a dirty to a clean energy in Golosov et al. (2014) to incorporate the role played by primary minerals and their potential recycling. We characterize the optimal paths of the energy transition under various mineral constraint scenarios. Mineral constraints limit the development of green energy in the long run: Low-carbon energy production eventually reaches a plateau. We run our simulations using copper as the limiting mineral and we allow for its full recycling. Even in the limiting case of a 100% recycling rate, after five to six decades green energy production is 50% lower than in the scenario with unlimited primary copper, and after 30 decades, GDP is 3–8% lower. In extension scenarios, we confirm that a longer life duration of green capital delays copper extraction and the green energy peak, whereas reduced recycling caps moves the peak in green energy production forward. 相似文献

Commercial aquaculture in India has come under attack for having caused negative agricultural and environmental impacts. This paper formulates an interactive model of non-renewable and renewable resources to characterize land allocations between aquaculture and agriculture in ecologically and economically sustainable fashion. Through an empirical application, various economic and policy circumstances that affect the optimal land allocation mix are evaluated. The aquaculture industry must address two economic effects: off-site negative effects on renewable food and other coastal resources, and on-site self-pollution of shrimp ponds. Current regulatory and land-use policies are inadequate to address these effects. 相似文献

The paper presents a dynamic partial equilibrium model which combines optimal renewable resource harvesting and optimal pollution control. Pollution accumulates as a slowly decaying stock and is assumed to affect the growth and the quality of the renewable resource stock. The aim is to maximize a social welfare functional which gives the present value of the difference between natural resource benefits and pollution control costs. The existence, uniqueness and the dynamic properties of the steady states are investigated. The analysis also gives a general result concerning the steady state of any two state variable optimal control problems. 相似文献

Technology Roadmapping (TRM) is a growing technique widely used for strategy planning and aligning technology with overall business objectives. Technology roadmaps are extensively used in many diverse fields at product, technology, industry, company and national levels. An increasing number of articles published on TRM and technology roadmaps indicate that there is a growing attention for TRM among the researchers from academia, industry and government. In this article, an overview of the application of TRM in renewable energy sector has been provided. After survey of the relevant academic literature and industry roadmaps, we tried to group the roadmaps related to the renewable energy technologies into national, industry/sector and organizational level roadmaps. Research findings indicate that goals and objectives of renewable energy roadmaps are different at these three levels. At national level, roadmaps focus on future energy security, energy dependence, energy policy formulation and environment protection. At industry/sector level, roadmaps are used to identify vision, common needs and evaluate barriers, constraints and risks faced by the industry from technical, political and commercial aspects. Organizational roadmap focuses on evaluation and prioritization of R&D projects to achieve the business goals. Similarly different methods, tools and approaches are used to develop roadmaps at different levels. Various other characteristics of these roadmaps are also discussed and analyzed. Research findings also indicate that greater numbers of roadmaps are developed for those renewable energy technologies undergoing rapid growth. Moreover, most of these roadmaps are developed in the regions where more research, development and deployment activities of renewable energy technologies is taking place. 相似文献

Landfill Construction and Capacity Expansion 总被引:2,自引:0,他引:2
We study the optimal capacity and lifetime of landfills taking into account their sequential nature. Such an optimal capacity is characterized by the so-called Optimal Capacity Condition. Particular versions of this condition are obtained for two alternative settings: first, if all the landfills are to have the same capacity, and second, if each of them is allowed to have a different capacity. In the second case we obtain an optimal control problem, with mixed elements of both continuous and discrete time. The resulting optimization problems involve dividing a time horizon of planning into several subintervals of endogenously decided length. The results obtained may be useful to address other economic problems such as private and public investments, consumption decisions on durable goods, etc. 相似文献

We study the effects of an economic policy in an endogenous growth general equilibrium framework where production of consumption
goods requires two resource inputs: a polluting non-renewable resource and a non-polluting labour resource. The use of the
former contributes to the accumulation of pollution in the atmosphere, which affects welfare. There is a specific research
sector associated with each of those resources. We provide a full welfare analysis, and we describe the equilibrium paths
in a decentralized economy. We go on to study the effects of three associated economic policy tools: a tax on the polluting
resource, and two research subsidies. We show that the optimal environmental policy has two main effects; it delays the extraction
of the resource and with it the level of polluting emissions and it reallocates research efforts, decreasing the amount put
into “grey” research to the benefit of “green” research. We also show that the environmental policy is grey-biased in the
short-term, and green-biased in the long-term. Finally, we compute the optimal values for these tools.

We consider trade between a ‘consumer’ country with an open access renewable resource and a ‘conservationist’ country that regulates resource harvesting to maximize domestic steady-state utility. In what we call the mild overuse case, the consumer country exports the resource good and suffers steady-state losses from trade, as suggested by the conventional wisdom that weak resource management standards confer a competitive advantage on domestic firms in the resource sector but cause welfare losses. Strikingly, however, when the resource stock is most in jeopardy, the conservationist country exports the resource good in steady state and both countries experience gains from trade. 相似文献

Phosphorus (P) is an essential input into agriculture with no substitute. Thus international and intertemporal P allocations greatly impact food security which requires increased food production for a growing world population. As high quality phosphorus mines are being depleted, recycling gains importance and developed countries explore new technologies for P recycling. We analyse the effects of P recycling in developed countries on global extraction of rock phosphates and the imports of developing countries. We build a resource extraction model for a competitive fertilizer market that reflects the fact that most developed countries have P-saturated soils while soils in many developing countries are P-deficient. Our model extends a simple cake eating problem. We consider two types of countries that differ in demand and recycling options. We find that P recycling in developed countries does not only prolong the resource life-time, but it also increases the developing counties' share of the resource. 相似文献

浅析矿产资源开发中的利益分配博弈 总被引:1,自引:0,他引:1
由于矿产资源的特殊性,利益分配不均现象在矿产资源开发中尤为显著,资源富饶的地区经济发展还较为落后,居民生活水平提高不大,矛盾冲突多,社会安定堪忧.本文根据对云南部分矿种和矿区的实际调研,利用相关的博弈理论和方法,构建了矿产资源开发企业和矿区居民之间的不完全信息动态博弈模型,通过对该模型精炼贝叶斯均衡的求解,表明矿产资源开发中企业倾向于向矿区居民分配很低的利益且这种分配策略属于“混同均衡”,进而推导出了各均衡点存在的必要条件,并以实际调研案例验证了其存在的真实性.在此基础上从监管、补偿机制及分配制度三个方面提出了确保在矿产资源开发中进行利益合理分配的对策建议,为维护矿区社会稳定、实现经济社会的可持续发展提供参考. 相似文献

能源是国民经济和社会发展的重要战略物资,是经济发展的命脉。近年来中国经济快速发展对能源的引致需求日益增加,国内的能源供给已经不能满足其需求,依赖能源进口且逐年增加的态势尤为明显。而与我国有着地缘优势的哈萨克斯坦油气资源较丰富,随着里海大陆架油气资源的发现,其油气资源储量更是逐年增加。这对能源消耗大国中国来说尤为重要。因此,中哈两国企业进行能源合作开发利用,不但可行且需要加快推进。本文以我国能源需求现状、哈萨克斯坦能源物质条件为基础,分析了中哈两国企业合作开发利用现状、优劣势,分别从中方和哈方寻找制约两国企业能源合作开发的限制性因素,并据此提出了相关的对策建议。该研究主要为为两国合作应对策略的制定提供参考依据。 相似文献

A model of a renewable resource is developed where the growth and quality of the resource are reduced by pollution. Ambient pollution concentrations and the renewable resource stock are modeled as stochastic processes. Conditions for the optimal harvest plan and the optimal emissions rate are derived. The effect of stochastic variations on the optimal management of the resource is analyzed. The steady-state joint probability distribution of the resource and pollution stocks is shown to exist under certain conditions. 相似文献

In this paper, we develop atheoretically consistent framework to incorporate theenvironmental effects of agricultural production andthe depletion of natural capital caused byagricultural production into the existing incomeaccounts. We apply the framework and adjust theincome attributed to the agricultural sector andeconomy-wide net national product (NNP) for the UnitedStates. Estimated adjustments to the incomeattributed to agriculture are in the range of $4billion and have declined as a percentage of net farmincome since 1982. 相似文献

国内外能源相对价格与中国的能源效率 总被引:13,自引:0,他引:13
提高能源效率是实现经济可持续发展和减少污染排放的根本途径。基于非线性平滑转换模型的分析显示,能源价格对能源效率的影响机制存在非线性的平滑转换。机制转换的主要引导因素是国内外能源价格指数的相对变化,机制转换的阈值近似为1。目前我国能源价格对能源效率的影响比较接近高效机制运行,增强能源价格的灵活性,可以实现能源消费者的自我选择,是提高我国能源效率的可行选择。 相似文献
