1a. Graph the long run position of a firm in monopolistic competition.
1b. Graph the typical monopolistic long run situation.
1c. Compare the two graphs and explain how they are similar.
Answer : 1a) The long-run situation of a monopolistically competitive firm is shown by the following picture's diagram. In long-run a monopolistically competitive firm earn zero economic profit.

1b) The long-run situation of a typical monopolist is shown by the following picture's diagram. In long-run a typical monopolist earn positive economic profit.

1c) By comparing above two graphs we get some similarities between monopolistically competitive firm's long run situation and a typical monopolist's long run situation. These are following :
i) In both graph the demand curve is downward sloping.
ii) In both graph the MR curve lies below the demand curve.
iii) In both graph the profit-maximizing condition is MR = MC.
iv) In both graph at profit-maximizing output level the price is higher than MC.
v) In both graph the profit-maximizing output level is inefficient.
Thus, both the typical monopolist and a monopolistically competitive firm are similar in long-run.
