Chicago's water market: Dynamics of demand, prices and scarcity rents

Chicago and its suburbs are experiencing an increasing demand for water from a growing population and economy and may experience water scarcity in the near future. The Chicago metropolitan area has nearly depleted its groundwater resources to a point where interstate conflicts with Wisconsin could accompany an increased reliance on those sources. Further, the withdrawals from Lake Michigan is limited by the Supreme Court decree. The growing demand and indications of possible scarcity suggest a need to reexamine the pricing policies and the dynamics of demand. The study analyses the demand for water and develops estimates of scarcity rents for water in Chicago. The price and income elasticities computed at the means are -0.002 and 0.0002 respectively. The estimated scarcity rents ranges from $0.98 to $1.17 per thousand gallons. The results indicate that the current prices do not fully account for the scarcity rents and suggest a current rate with in the range $1.53 to $1.72 per thousand gallons.

Economics of utilization of high sulfur coal resources - an integrated market approach

Before the Clean Air Act Amendments of 1990, coal policies - especially coal research policies - were geared to find a solution to the sulfur emission problem. However, technologies to reduce sulfur emissions cannot be tailored for a single coal. A technology that will clean Illinois coal to compliance levels will do the same, or nearly the same, for most other types of coal. This paper will discuss an integrated approach to the analysis of the future of coals from different regions in the United States and its implications for coal-related policies by government and industry.

Environmental benefits vs. costs of geologic mapping

Boone and Winnebago Counties, Illinois, U.S.A., were selected for this study, required by the Illinois State Senate, because mapping and environmental interpretations were completed there in 1981. Costs of geologic mapping in these counties in 1990 dollars were $290,000. Two estimates of costs of statewide mapping were made, one extrapolated from Boone and Winnebago Counties ($21 million), the other estimated on the basis of differences between the Boone/Winnebago program and proposed mapping program for the State of Illinois ($55 million). Benefits of geologic information come in the form of future avoided costs for environmental cleanup. Only the quantifiable data, available from a few sites, were included. Data collection, based on 55 personal interviews in Boone and Winnebago Counties, were grouped into four cumulative categories with increasing variability. Geologic maps alone cannot account for all avoided costs of future cleanup. Therefore, estimated benefits were reduced by 50, 75, and 90 percent in three scenarios. To account for delays in proper utilization of knowledge gained from a mapping program, a 10-yr delay in benefit realization was assumed. All benefits were converted to 1990 dollars. In benefit category 4, benefit-cost ratios for Boone/Winnebago Counties ranged between 5 and 55. Statewide projection of benefits was based on county areas and an aquifer contamination potential score for each county. Statewide benefit-cost ratio in benefit category 4 ranged from 1.2 to 14 ($21 million mapping costs) and from 0.5 to 5.4 ($55 million mapping costs). ?? 1992 Springer-Verlag New York Inc.

Economics of the coal industry east of the Mississippi, 1973-1982

Government regulations on health, safety and environment have been poppular blamed for the declining productivity in U.S. coal mines since 1970. The stagnation in the coal industry east of the Mississippi is alleged to have been caused by this declining productivity and by the growth of cheaper and cleaner coal production west of the Mississippi. Economic evidence suggests, however, that productivity declines were more due to a relative lowering of labor costs in comparison with coal prices and due to work stoppages. The development of western coals fields was spurred by growth in local demand and had only a relatively small impact on coal production east of the Mississippi. Problems of the eastern coal industry are rooted mainly in slow economic growth in eastern U.S. which must be addressed in the long-term interests of the eastern coal industry.
