Refer to the above figure. An unregulated natural monopolist would choose A) output rate of Q1 and price P2. B) output rate Q1 and price PS. C) output rate Q4 and price PI D) output rate Q3 and price P3. Refer to the above figure. If the government requires the natural monopolist to charge the efficient price, it will charge price A) PI and sell Q4 units. B) P2 and sell Ql units. C) Ps and sell Ql units. D) P3 and sell Q3 units. 63) Refer to the above figure. Suppose the government requires the natural monopolist to charge the efficient price. Then profits for the firm will be A) profits equal to Ql times distance a-b. B) zero. C) losses equal to Q3 times distance d-e. D) losses equal to Q4 times distance f-g. 64) Refer to the above figure. Regulators cannot force natural monopolies to operate in the long run at a loss. Therefore, they usually require the firms to charge a price equal to A) marginal cost, which is P2. B) marginal cost, which is Pl. C) average cost, which is P3. D) average cost, which is P4.
