c.fall from $15 per hour to $12 per hour and 100 more people will be employed.

10) Which of the following statements comparing monopoly with competition is

a.A monopolist produces a higher level of output and charges a lower price than a

b.With perfect price discrimination, the total surplus under monopoly can be the same
as under competition.
