14. A natural monopoly exists when:
a few firms collude to make one large firm.

16. In the figure, the natural monopoly:
would incur an economic profit if regulated to produce where price is less than marginal cost.
would incur an economic profit if regulated to charge a price equal to average total cost.
creates more consumer surplus if regulated to produce either where price equals marginal cost or price equals average total cost.
creates more consumer surplus if regulated to produce where price is above the average total cost.
eliminates consumer surplus if regulated to produce where price is above average total cost.
