Suppose the local electrical utility, a legal monopoly based on economies of scale, was split into four films of equal size, with the idea that eliminating the monopoly would promote competitive pricing of electricity. What do you anticipate would happen to prices?
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?
A friend of yours is considering two cell phone service providers. Provider A charges 120 per month for the service regardless of the number of phone calls made. Provider B does not have a fixed service fee but instead charges 1 per minute for calls. Your friend's monthly demand for minutes of calling is given by the equation QD = 150 50P, where P is the price of a minute. a. With each provider, what is the cost to your friend of an extra minute on the phone? b. In light of your answer to (a), how many minutes with each provider would your friend talk on the phone? c. How much would she end up paying each provider every month? d. How much consumer surplus would she obtain with each provider? (Hint: Graph the demand curve and recall the formula for the area of a triangle.) e. Which provider would you recommend that your friend choose? Why?
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. (This is not a research assignment, but a thought assignment based on what you have learned in this chapter.)

Suppose an airline sells air tickets to two types of customer – business travelersand vacation travelers. Their estimated demand elasticities are -2.5 and -4.0respectively.Suppose the marginal cost is constant at $240, and the services provided to thetwo types of customer are similar.a. Based on the given information, explain with TWO practical reasons whether theairline should charge a higher price on business travelers or vocational travelers.Explain without calculation.
Suppose a monopoly market has a demand function in whichquantity demanded depends not only on market price (P) butalso on the amount of advertising the firm does (A, measuredin dollars). The specific form of this function isQ =(20 - P2) (1 + 0.1A - 0.01A2).The monopolistic firm’s cost function is given byC = 10Q + 15 + A.a. Suppose there is no advertising (A = 0). What outputwill the profit-maximizing firm choose? What market price will this yield? What will be the monopoly’sprofits?b. Now let the firm also choose its optimal level of advertising expenditure. In this situation, what output levelwill be chosen? What price will this yield? What will thelevel of advertising be? What are the firm’s profits in thiscase? Hint: This can be worked out most easily by assuming the monopoly chooses the profit-maximizing pricerather than quantity.
Assuming you are the managing director of a firm that produces three goods: A, Band C. The price elasticity of demand for A is 1.2, for B it is 1.00 and for C it is 0.75.It is known that he firm is experiencing serious cash flow problems and you have toincrease total revenue as soon as possible. If you were in a position to set the pricesfor these goods, what would be your pricing strategy for each product
