Extraction costs in the theory of exhaustible resources
نویسندگان
چکیده
This paper has two objectives. First, it reformulates the theory of optimal use of an exhaustible resource with more attention to the costs of extraction than has been customary in the literature. The output and shadow-price implications of optimal extraction are studied under these broader assumptions. Second, the paper provides some numerical solutions of a simple two-grade case, to give some feeling for the quantitative importance of changes in the supply of exhaustible resources. Our most striking result is, in fact, the suggestion that relatively large changes in resource availability generate very small changes in the sustainable level of final consumption.

Optimal Extraction of Exhaustible Resources under Resource Tax Reform in China
This paper discusses the impacts of resource tax reform on the optimal resources extraction in China when the time of resource tax reform and the ways of taxes levy are uncertain. Based on the assumption that the process for accepting resource tax reform follows Poisson process, we first divide resource extraction into two processes by using the idea of dynamic planning. We then apply the optim...
متن کاملSustainable Development, Renewable Resources and Technological Progress
Conflicts between optimality and sustainability are typical in the literature on sustainable development. Using the ‘‘capital-resource’’ growth model, Pezzey and Withagen (1998, Scandinavian Journal of Economics 100 (2), 513–527) have proved that if natural resources are exhaustible, the time-path of consumption is single-peaked, declining from some point in time onwards. This paper extends the...
متن کاملGames and Resources
This chapter presents a sequence of simple and related models to analyze the strategic use of natural resources. Game theory is the natural tool for such an analysis, whether the resource is private or publicly owned, whether it is renewable or exhaustible, whether the game is static or dynamic, and whether or not the users can strategically invest in technologies. Equilibrium extraction is too...
متن کاملGame Theoretic Models for Energy Production
We give a selective survey of oligopoly models for energy production which capture to varying degrees issues such as exhaustibility of fossil fuels, development of renewable sources, exploration and new technologies, and changing costs of production. Our main focus is on dynamic Cournot competition with exhaustible resources. We trace the resulting theory of competitive equilibria and discuss s...
متن کاملThe Grey Paradox: How Fossil-fuels Owners Can Bene t From Carbon Taxation.∗
This paper studies the distributional impacts of optimal carbon taxation on fossilfuels owners. We show that optimal carbon taxation can increase the pro ts of owners of a carbon-emitting exhaustible resource. Such phenomenon contrasts with claims from fossil-fuels owners especially from OPEC member countries that carbon taxation will undermine their pro ts. We build a theoretical model of reso...
