1. Consider the problem of regulating acid rain in the eastern US. Assume emissions are generated in the Midwest and the Northeast but acid rain damage only occurs in the Northeast. One million tons of emissions in the Midwest results in 1 microgram per square meter of deposition; one million tons of emissions in the Northeast results in 2 micrograms per square meter of deposition. Damage (in millions of dollars per year) from deposition (d) is given by: D(d) = d^2/2, where d is measured in micrograms per square meter of deposition. Prior to any imposition of emission controls, the Midwest was emitting only 3 million tons per year, whereas the Northeast was emitting 5 million tons per year. Pollution control costs in either region are given by: C(k) = k^2/2, where k is the amount of emission reduction per year in a region, in millions of tons.Â
