Question
In the context of pollution control, define and
distinguish between the Marginal Abatement Cost (MAC) and the Total Abatement Cost (TAC) for a firm.Solution
Solution: The Marginal Abatement Cost (MAC) is the cost incurred by a firm to reduce pollution by one additional unit. It typically increases as the level of abatement rises (it gets progressively harder/more expensive to clean up the last few units). The Total Abatement Cost (TAC) is the area under the MAC curve, representing the cumulative cost of all abatement efforts up to a specific level.
