Consider the following market demand schedule and total costs for a monopoly.

Q P TR TC MR MC Profit                                        
0 45   4                                              
1 40   9                                              
2 35   19                                              
3 30   39                                              
4 25   61                                              
5 20   91                                              
6 15   130                                              
7 10   172                                              

a) Fill in the blanks.

b) How is the relationship between price and MR different between monopolistic and perfectly competitive markets?

c) Would the demand curve facing a monopolistic competitive market be more or less elastic than the demand curve facing a monopolist, why? Do firms in a monopolistically competitive market make long-run economic profits, why or why not?
