解题思路:当 MR = MC时利润最大
Answer (A) is correct . For profit maximization, a firm operating under pure competition should produce the level of output at which price is equal to marginal cost. Since price and marginal cost are both $20, the firm is already at its profit-maximizing position.
Answer (B) is incorrect because A firm should not decrease output when price is at least equal to marginal cost.
Answer (C) is incorrect because There is no incentive to increase production when marginal cost is equal to selling price.
Answer (D) is incorrect because A?firm should not shut down as long as price exceeds variable cost; any excess of price over variable cost provides a contribution toward the coverage of fixed costs.
