Chapter 16, Problem 1.1P

To determine

Why the imposition of pollution tax of more than the actual value of the damage is unfair.

Explanation of Solution

When firms in the industry that pollute are charged with tax rates of higher value than the actual pollution value caused by the firm, the firm would increase the price of its commodity to make up for the additional cost incurred. Thus, the consumers of the firms have to pay an excessive price for the commodities, which have an adverse impact on the consumers. Efficient pollution taxation is the tax rate which has a penalty equal to the marginal damage cost by the firm. The following diagram shows the optimal pollution taxation:

When the penalty is equal to the marginal damage cost incurred by the polluting firm, the price paid by the consumers for the product would increase. The increase in the price of the commodity of the polluting firm would take place up to the point where the price equals the marginal social cost of the pollution. Excess tax of the marginal social cost would cause the price to increase beyond the marginal social cost, which is an inefficient result.
