1 How does monopolistic competition differ from the pure competition in its basic characteristics? From pure monopoly? Explain fully what product differentiation may involve. Please explain how the entry of firms into its industry affects the demand curve facing a monopolistic competitor and how that, in turn, affects its economic profit.

2 "Competition in quality and service may be just as effective as price competition in giving buyers more for their money." Do you agree? Why? Explain why monopolistically competitive firms frequently prefer nonprice to price competition.

3 Critically evaluate and explain:
a. In monopolistically competitive industries, economic profits compete away in the long run; hence, there is no valid reason to criticize such industries' performance and efficiency.
b. In the long run, monopolistic competition leads to a monopolistic price but not to monopolistic profits.
