7) Critically evaluate and explain each statement:

a. Because they can control product price, monopolists are always assured of profitable production by simply charging the highest price consumers will pay.

d. The more profitable a firm, the greater its monopoly power.

e. The monopolist has a pricing policy; the competitive producer does not.

Chapter 9:

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

2). Compare the elasticity of the monopolistic competitor's demand with that of a pure competitor and a pure monopolist. Assuming identical long-run costs, compare graphically the prices and outputs that would result in the long run under pure competition and under monopolistic competition. Contrast the two market structures in terms of productive and allocative efficiency. Explain the following statement: "Monopolistically competitive industries are characterized by too many firms, each of which produces too little."
