The government can reduce total pollution in the area to 6 units by choosing between the following two methods: Methods to Reduce Pollution1.The government imposes pollution standards using regulation.2.The government issues tradable pollution permits. The costs faced by each firm are different, so it is more difficult for some firms to reduce pollution than others.
