In a departure from past contingent valuation research of groundwater quality, this paper estimates a damage function for nitrate exposures based on actual water test results of individual wells. From the perspective of reliability, it is argued that such a full information approach more closely...

Geologic estimates of remaining global petroleum resources place about 50% in the Persian Gulf. Production costs are estimated at $5 per barrel there, and $15 per barrel in the North Sea and Alaska. Using mathematical methods derived from depletion theory is utilized to explain the $15-$20 per...

A real option analysis of dry-grind corn ethanol plants compared to a standard net present value analysis (NPV) shows that the option values increase entry prices and lower exit prices of investment and disinvestment considerably. For a large plant, the gross margin of ethanol price over the...

Corn ethanol plants consume large amounts of corn and their location has the potential to alter local crop prices and surrounding agricultural land values. The relationship between ethanol plant location and agricultural land prices is examined using data obtained from the Agricultural Credit...

A combination of higher oil production as well as higher oil prices is creating oil revenue windfalls for some Sub Saharan African countries. If well managed, these revenues have the potential to reduce poverty and bridge the development gap; if not they could lead to Dutch disease and an...

With a mandate, U.S. policy of ethanol tax credits designed to reduce oil consumption does the exact opposite. A tax credit is a direct gasoline consumption subsidy with no effect on the ethanol price and therefore does not help either corn or ethanol producers. To understand this, consider...

This paper addresses the broad question ofwhere to locate authority for tropical biodiversity conservation considering: (1) community-based natural research management (CBNRM) overreaches the indisputable place of local communities in tropical conservation efforts; (2) the most promise for...
