Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for...

This paper presents a survey of issues and concerns raised in recent literature on the application of market-based approaches to greenhouse effect policy with an emphasis on tradeable emission permits. The potential advantages of decentralized decision-making -- cost-effectiveness or allocation...

We study how restricting CO2 emissions affects resource prices and depletion over time. We use a Hotelling-style model with two non-renewable fossil fuels that differ in their carbon content (e.g. coal and natural gas) and in addition are imperfect substitutes in final good production. We show...

This paper highlights several management practices from the oil and gas industry to support the proposition that financial performance in the finite, non-renewable resource business relates more to upstream rather than downstream activities. Based on the analysis of nine oil and gas companies,...

Exact optimal paths are calculated for two closed, continuous-time economies with explicit functional forms for utility from consumption, and for production from human-made capital and a non-renewable resource. Features of the first economy are non-linear utility, hyperbolic utility discounting...

Currently the gold mining industry is taxed differently to other industries. It is taxed on a two-tier system. The nature of the gold mining tax formula encourages the mining of marginal gold ores. Firms that are involved in the mining of gold are subjected to a "tax tunnel", which is a tax free...

A detailed analysis of six Clean Coal projects revealed that recoupment decisions made by the Department limited its ability to recover the taxpayers` investment. These decisions exempted foreign sales, excluded some domestic sales on certain projects, and lowered the repayment rate on some...
