Structural change in the coal industry: Coal industry concentration trends, 1970--1994. Final report
- Energy Ventures Analysis, Inc., Arlington, VA (United States)
This report evaluates the historical and current concentration of the US coal industry, with special consideration given to its potential impact on competitiveness and coal Prices. Four time periods are studied: 1970, 1980, 1990, and 1994. The report Presents data at various levels: nationwide, eastern US, western US, and subregions -- Powder River Basin, Rockies, Northern Appalachia, Central Appalachia, Southern Appalachia, Illinois Basin, and several smaller areas. The report presents data on mine size, number of mines, coal Prices, Production, and ownership. Herfindahl Hirschman indices (the surn of squares Of companies` market shares) were calculated on the coal Production and ownership data to represent concentration. Through these periods, the coal industry has been relatively unconcentrated aid highly competitive. However, in most parts of the country, concentration has increased dramatically since 1990, surpassing historical levels. Concentration is also expected to continue increasing. The effects of such concentration are felt unevenly, depending of factors unique to each coal buyer and each coal company merger, acquisition, or divestment. Generally, the population of potential suppliers for each buyer is limited quality constraints. Those buyers who are greatly limited by such factors can experience dramatic changes in the concentration of their supplier populations by mergers that may have little impact on other buyers.
