Unformatted text preview: EC 145E Environmental Economics VCI Dr. Bresnock There are 2 main techniques to measure the benefits of improvements in environmental quality: (a) calculating the damages directly with the emissions damage function , and (b) estimating the willingness-to-pay for improvements in environmental quality. (1) Physical Aspects- in order to calculate the damages associated with emissions the physical circumstances that lead to such damages must be calculated first . This process has 5 steps: (a) measure the emissions , (b) use dispersion models to determine the ambient quality that results from the emissions, (c) estimate the human exposure to the ambient quality found in (b) , (d) estimate the physical impacts of (c) , and (e) estimate the $ damages associated with the ph y sical impacts in (d) . The most important damage caused by environmental pollution relates to human health , i . e. increased mortality and morbidity , increases in diseases . This is complex analysis because of other factors besides ambient pollution that affect human health. (a) Health Costs- "cost of illness " (COI) analysis estimates the increased medical and other costs associated with pollution-related illnesses. These estimates are direct (i . e . costs of medical visits , medications,) and indirect (i.e. lost productivity , lost work time). Benefits of pollution control are reducing these health costs , and are considered a minimum , or lower- bound , on assessing these benefits . Environmental Economics Lecture 4 Creating "health indices", assigning values to different he a lth states, and then monetizing differences in these indices are an alternative to the COI method, but they do not rely on willingness-to-pay as a measure of value. (b) Effects of Pollution on Production Costs - reduced yields of crops, timber, fish, and effectiveness of workers, can lead to increases in production costs as a result of pollution. Ex . costs to c lean up water, decontaminate soil s , and sluggish worker performance. In all of these cases , pollution ~ i the MPC (Marginal Private Costs) of the affected firms. ; ; . ,. \- . 1- , O 'vv\ .. O- f v J o . /' *-- v " I ( J ' ) r ' ! ,- '- l . ' . , ,: .

Similar analysis as (b). Some of these damages are aesthetic and may be captured as reduced visual values in land and property values. Any costs associated with s witching to other materials that are less likely to deteriorate should also be included. "Dose-response" analysis can be performed to calculate the extent of the deterioration associated with deterioration resulting from different amounts of pollutants....
