Compared with a firm under perfect competition, a monopoly with the same cost curves usually:
A. Produces less and charges a higher price✓ 答案
B. Produces more at a lower price
C. Always sets P = MC
D. Earns the same profit in both structures
解說
Restricting output lets the monopolist raise price above marginal cost, so P > MC. That is a loss of allocative efficiency, though total surplus is also reduced by the deadweight loss.
