Imagine a monopolist could charge a different price to every customer based on how much he or she were willing to pay. How would this affect monopoly profits?

Is a monopolistically competitive firm productively efficient? Is it allocatively efficient? Why or why not?

From the graph you drew to answer Exercise 11.6, would you say this transit system is a natural monopoly? Justify. Use the following information to answer the next three questions. In the years before wireless phones, when telephone technology requited having a wile matting to every home, it seemed plausible that telephone service had diminishing average costs and might require regulation like a natural monopoly. For most of the twentieth century, the national U.S. phone company was AT&T, and the company functioned as a regulated monopoly. Think about the deregulation of the U.S. telecommunications industry that has occurred over the last few decades.
