13 Question (2 points) e See page 670 Two firms (A and B) run separate mining companies in the same forest. Both pollute the river flowing through the forest with debris. Currently, each company releases 50 pounds of debris per month into the river. The table below shows the costs associated with reducing debris in 10-pound increments. Firm A Firm B Total cost of reducing debris by 10 pounds $5 $2 Total cost of reducing debris by 20 pounds $15 $6 Total cost of reducing debris by 30 pounds $30 $12 Total cost of reducing debris by 40 pounds $50 $20 Total cost of reducing debris by 50 pounds $75 $30Suppose the government wants to achieve a debris reduction of 30 pounds per month (that is, reduce the amount of debris to 70 pounds). Assume that if a firm is indifferent between buying a debris permit or reducing pollution, it will choose to buy the permit. Suppose the government issues seven 10-pound permits. To release debris, a firm must hold a permit for every 10 pounds of debris. If all permits are sold off to the firms at a single price per permit, every month the price would be between $ (low end) and $ (high end)
