The diagram below shows the marginal cost of pollution abatement for two firms, Firm X and Firm Y.
FIGURE 17-4
Refer to Figure 17-4. Suppose Firms X and Y are each abating QR units of pollution. From this point, if Firm X reduces pollution by one unit and Firm Y increases pollution by one unit, then
◦ total pollution remains the same, but the total cost of abatement falls.
◦ the total cost of abatement remains the same, but pollution increases.
◦ total pollution remains the same, but the total cost of abatement increases.
◦ the total costs of abatement and the amount of pollution do not change.
◦ the total cost of abatement remains the same, but pollution falls.
