Scenario 1
Assume there are two steel plants in a city. The first one operates a plant that is fifty
years old and the second one is an ultra modern facility. Each dumps thermal water into
the same river. Both firms add 5 million gallons of thermal water to the river each. The
government has mandated that each steel company only dump 1 million gallons. The
cost of abating the thermal water for the old plant is 25 cents per gallon. By contrast the
modern plant only costs 5 cents per gallon.
Using Scenario 1, calculate the total cost of pollution when both steel companies are
allowed to pollute only one million gallons of thermal water each and the right is not
transferable or tradable.
