Hypothetically, Suppose a Recent Study of Hazardous Waste Abatement (A)

Essay

Hypothetically, suppose a recent study of hazardous waste abatement (A) arrives at the following national estimates for abating chemical solvents: MSB = 100 - 0.75A and MSC = 20 + 0.50A, where A is measured in millions of tons per year, and costs are measured in millions of dollars.
a. Based on this information, what would be the national standard for an allocatively efficient abatement?
b. Under what conditions would this level be efficient at the regional level?
c. If instead the government set the abatement standard at 50 million tons per year, would that standard be too lenient or too restrictive at the national level? Support your answer with specific values.
