For ecological economic evaluation based on the unified biophysical matrix this research illustrates an updated emergy synthesis in terms of embodied cosmic exergy instead of embodied solar energy, which successes the foundation of systems ecological theory but changes the starting point for the estimation from simply the sun to the cosmos. According to the modified definition implicating expli...

This paper investigates the implications of an intertemporally dependent demand structure in the market for an exhaustible resource. The demand structure is derived endogenously in a partial equilibrium model where price-taking users combine the resource with capital to produce final output. It is shown that, when demand for the resource is modelled explicitly as a derived demand, the common as...

The aim of this article is to review issues related to the incorporation of scarce natural resources in the theory of economic growth and development. More specifically, we shall concentrate on the role of non-renewable resources. A nonrenewable resource is a natural resource the amount of which on earth is finite and which has no natural regeneration process (at least not within a relevant tim...

This paper studies monopoly extraction of a nonrenewable resource with the presence of a competitively supplied capacity constrained renewable substitute. The monopolist staves off the renewable supply when the latter becomes competitive and then lets the resource price jump up. © 2013 Elsevier B.V. All rights reserved.

Harold Hotelling’s 1931 article on the economics of exhaustible resources is considered groundbreaking in history nonrenewable resource analysis. innovation has been characterized by comparing his work with other contributions dealing conservation issues. It also connected to earlier depreciation, published 1925, for using same kind mathematical formalism. This further explores this second rese...

The increase of pollutants in the environment and rapid decrease nonrenewable energy resources are putting immense pressure on ecosystems. Semiconductor oxides possess some unique properties that may provide a foundation for development advanced functional materials to address pressing environmental issues. Among various metal oxides, WO3 based nanomaterials with an array morphologies sizes can...
