Demand curves faced by monopolists and competitive firms

3. How does the demand curve faced by a purely monopolistic seller differ from that confronting a purely competitive firm? Why does it differ? Of what significance is the difference? Why is the pure monopolistâ??s demand curve typically not perfectly elastic?

5. Suppose a pure monopolist is faced with the demand schedule that follows and the same cost data as the competitive producer discussed in question #3 (above).
Calculate the missing total-revenue and marginal-revenue amounts, and determine the profit-maximizing price and profit-earning output for his monopolist. What is the monopolistâ??s profit?

9. U.S. Pharmaceutical companies charge different prices for prescription drugs to buyers in different nations, depending of the elasticity of demand and government-imposed price ceilings. Explain why these companies, for profit reason, oppose laws allowing reimportation of their drugs back into the United States.
