Abstract

Firms that extract and produce multiple metals are an important component of mineral supply. The reaction of such firms to changes in their relevant output prices is tested econometrically for five metals using a panel representing more than 100 mines across the time period 1991-2005. Here, the estimation strategy is drawn from joint production theory, namely a flexible form, dual revenue approach with seemingly unrelated regressions (SUR) estimation. The results indicate that multi-product mines respond (in the short run) to higher prices of a particular metal by reducing output of that metal (indicative of low-grading behavior) and increasing and/or decreasing output of joint metal products (indicative of substitutes and complements in supply). As a result, the price responses are not readily explained by a metal's classification as a by-product or main product based on revenue.

Analysis of the supply of and demand for stainless steel in the United States

Journal Article Katrak, F E ; King, T B ; Clark, J P - Mater. Soc.; (United States)

A study conducted for the Division of Ferrous Metals of the US Bureau of Mines seeks to analyze the various factors affecting the supply of and demand for wrought stainless steel products in the US and to construct a dynamic model that would facilitate long-run policy analyses. The integrated specialty and carbon steel firms that melt, as well as process, stainless steel were considered to be the principal components of the domestic-supply sector. The demand for stainless steel mill products was estimated with an econometric model of apparent consumption in seven major end-use sectors and to the year 2000. Themore »« less
Market for Ethanol Feed Joint Products

Technical Report

This report presents results of econometric estimations and mathematical simulations of markets for joint feed products of motor ethanol. The major issues considered are the nature of current market price relationships, effects on prices, including feed substitutes prices, and effects of demands for increased use of distillers' grains and gluten meal. The econometric section shows that soybean meal was by far the dominant force in the pricing of the two products. However, neither one could be adequately explained without the inclusion of corn in the estimating equations. Later research shows that this was due to the importance of both feedsmore »« less

Upgrading drained coal mine methane to pipeline quality: a report on the commercial status of system suppliers

Technical Report Carothers, F P ; Schultz, M L

In today's scenario of growing energy demand worldwide and rising natural gas prices, any methane emitted into the atmosphere is an untapped resource of energy and potentially a lost opportunity for additional revenue. In 2005, 9.7% of the total US anthropogenic emissions of methane were attributed to coal production. In recent years, many gassy coal mines have seized the opportunity to recover coal mine methane (CMM) and supply it to natural gas pipeline systems. With natural gas prices in the US exceeding $7.00 per million Btu, CMM pipeline sales brought in an annual revenue topping $97 million in 2005. However,more »« less
Relationship between refined product imports and refined product prices in the United States

Journal Article Gonzales, J J - Energy J.; (United States)

An empirical investigation of the competitiveness of refined product imports in the domestic market focuses on motor gasoline, residual fuel oil, middle distillates, and jet fuel. The main concern is the degree to which domestic product prices are determined by the price of imported products. An econometric model estimates the elasticity of substitution between domestic output and imports of the four products. The results show that their markets are isolated from the world product markets. The US continues to be an active importer of refined products, but for reasons unrelated to prices. This implies that any measure that affects themore »« less

Tax revenue and innovations in natural gas supply: New Mexico

Conference Ulibarri, C A ; Marsh, T L

This paper develops an econometric model of natural gas supply at the state-level using New Mexico as a case study. The supply model is estimated using annual time series observations on production levels, delivered prices, proved reserves, existing wells, and extraction costs. The authors validate the model against historical data and then use it to consider the fiscal impacts on state tax revenue from innovations in extraction technologies.
