question

"No firm is completely sheltered from rivals; all firms compete for consumer dollars. If that is so, then pure monopoly does not exist." Do you agree? Explain. How might you use the concept of cross elasticity of demand to judge whether monopoly exists?

answer

Though it is true that "all firms compete for consumer dollars," it is playing on words to hold that pure monopoly does not exist. If you wish to send a first-class letter, it is the postal service or nothing. Of course, if the postal service raises its rate to $10 to get a letter across town in two days, you will use a courier, the phone, or you will fax it. But within sensible limits, say a doubling of the postal rate, there is no alternative to the postal service or anything like it at a comparable price.

The same case can be made concerning the pure monopoly enjoyed by the local electricity company in any town. If you want electric lights, you have to deal with a single company. It is a pure monopoly in that regard, even though you can switch to oil or natural gas for heating. Of course, you can use oil, natural gas, or kerosene for lighting too, but these are hardly convenient options.

The concept of cross elasticity of demand can be used to measure the presence of close substitutes for the product of a monopoly firm. If the cross elasticity of demand is greater than one, then the demand that the monopoly faces is elastic with respect to substitute products, and the firm has less control over its product price than if the cross elasticity of demand were inelastic. In other words, the monopoly faces competition from producers of substitute products.

Note that a negative cross price elasticity of demand indicates that two goods are complements rather than substitutes.

question

It has been proposed that natural monopolists should be allowed to determine their profit-maximizing outputs and prices and then government should tax their profits away and distribute them to consumers in proportion to their purchases from the monopoly. This proposal

answer

does not consider that the output of natural monopolists would still be at the suboptimal level where P > MC

question

answer

No, the proposal does not consider that the output of the natural monopolist would still be at the suboptimal level where P > MC. Too little would be produced and there would be an underallocation of resources. Theoretically, it would be more desirable to force the natural monopolist to charge a price equal to marginal cost and subsidize any losses. Even setting price equal to ATC would be an improvement over this proposal. This fair-return pricing would allow for a normal profit and ensure greater production than the proposal would.

question

Assume a monopolistic publisher has agreed to pay an author 10 percent of the total revenue from the sales of a text. Will the author and the publisher want to charge the same price for the text? Explain.

answer

The publisher is a monopolist seeking to maximize profits. This will occur at the quantity of output where MC = MR. (See the graph below.)

question

U.S. pharmaceutical companies charge different prices for prescription drugs to buyers in different nations, depending on elasticity of demand and government-imposed price ceilings. U.S. pharmaceutical companies, for profit reasons, oppose laws allowing reimportation of drugs to the United States because reimportation would

answer

make it much more difficult to maintain the differing prices.

question

The socially optimal price (P = MC) is socially optimal because:

answer

It achieves allocative efficiency.

question

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

answer

U.S. pharmaceutical companies are price discriminating based in part on the different elasticities of demand in different nations. Reimportation allows reselling of the goods, making it more difficult to price discriminate. To the extent they could still charge different prices, the difference in prices would have to be small enough so that reimportation was not profitable. Prohibition of reimportation would allow pharmaceutical companies to charge the profit-maximizing price in each nation, without fear of being undercut back in the United States by those in nations where the drugs are cheaper.

question

Assume that a pure monopolist and a purely competitive firm have the same unit costs. Contrast the two with respect to (a) price, (b) output, (c) profits, (d) allocation of resources, and (e) impact on income transfers. Since both monopolists and competitive firms follow the MC = MR rule in maximizing profits, how do you account for the different results? Why might the costs of a purely competitive firm and those of a monopolist be different? What are the implications of such a cost difference?

answer

With the same costs, the pure monopolist will charge a higher price, have a smaller output, and have higher economic profits in both the short run and the long run than the pure competitor. As a matter of fact, the pure competitor will have no economic profits in the long run even though it might have some in the short run. Because the monopolist does not produce at the point of minimum ATC and does not equate price and MC, its allocation of resources is inferior to that of the pure competitor. Specifically, resources are underallocated to monopolistic industries. Since a pure monopolist is more likely than the pure competitor to make economic profits in the short run and is, moreover, the only one of the two able to make economic profits in the long run, the distribution of income is more unequal with monopoly than with pure competition.

In pure competition, MR = P because the firm's supply is such an insignificant part of industry supply that its output has no effect on price. It can sell all that it wishes at the price established by demand and the total industry supply. The firm cannot force the price up by holding back part or all of its supply.

The monopolist, on the other hand, is the industry. When it increases the quantity it produces, price drops. When it decreases the quantity it produces, price rises. In these circumstances, MR is always less than price for the monopolist; to sell more it must lower the price on all units, including those it could have sold at the higher price had it not put more on the market. When the monopolist equates MR and MC, it is not selling at that price: The monopolist's selling price is on the demand curve, vertically above the point of intersection of MR and MC. Thus, the monopolist's price will be higher than the pure competitor's.

Economies of scale may be such as to ensure that one large firm can produce at lower cost than a multitude of small firms. This is certainly the case with most public utilities. And in such industries as basic steel-making and car manufacturing, pure competition would involve a very high cost. On the other hand, monopolies may suffer from X-inefficiency, the inefficiency that a lack of competition allows. Monopolies may also incur nonproductive costs through "rent-seeking" expenditures. For example, they may try to influence legislation that protects their monopoly powers.

question

The demand curve faced by a purely monopolistic seller is

answer

downward sloping, whereas that facing the purely competitive firm is perfectly elastic.

question

The demand curve facing a

answer

purely competitive firm is perfectly elastic, because the purely competitive firm may sell all that it wishes at the equilibrium price.

question

The pure (profit maximizing) monopolist's demand curve is not

answer

perfectly inelastic, because MR is negative when demand is inelastic, so MR = MC < 0

question

LAST WORD Using Big Data to set personalized prices cannot be done with 100 percent precision. What would happen if personalized prices were set higher than customers' reservation prices? Would this possibility reduce the incentive to set the highest possible personalized prices? How can consumers protect themselves from personalized prices?

answer

If personalized prices are set higher than a customer's reservation price, two things could happen. If the company is truly a monopoly, the customer may not purchase the product, due to the destruction of the customer surplus. If there is competition in the market, the high personalized price may push the consumer to shop around, and ultimately buy the product from a competing seller.

This possibility does reduce the incentive to set the highest possible personalized price because the seller doesn't want to scare away the consumers. They want to preserve some consumer surplus and therefore give the consumer incentive to purchase the item from them and not bother shopping around.

The more competitive the market, the bigger the consumer surplus. If the consumer doesn't shop around, she is creating a monopoly situation. The easiest way for consumers to protect themselves is to compare prices with multiple companies to ensure they aren't paying a monopoly-like price.

question

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 monopolist's demand curve not perfectly inelastic?

answer

The demand curve facing a pure monopolist is downward sloping; that facing the purely competitive firm is horizontal, or perfectly elastic. This is so for the pure competitor because the firm faces a multitude of competitors, all producing perfect substitutes. In these circumstances, the purely competitive firm may sell all that it wishes at the equilibrium price, but it can sell nothing for even so little as one cent higher. The individual firm's supply is so small a part of the total industry supply that it cannot affect the price.

The monopolist, on the other hand, is the industry and therefore is faced by a normal downward-sloping industry demand curve. Being the entire industry, the monopolist's supply is big enough to affect prices. By decreasing output, the monopolist can force the price up. Increasing output will drive it down.

The fact that the monopolist could sell the same amount at higher and higher prices that would ensure that the profit-maximizing monopolist would not, in fact, sell in this perfectly inelastic range of the demand curve. Indeed, the monopolist would not sell in even the still slightly inelastic range of the demand curve. The reason is that so long as the demand curve is inelastic, MR must be negative, but since the MC of any item can hardly be negative also, the monopolist's profit must decrease if it produces here. To equate a positive MR with MC, the monopolist must produce in the elastic range of its demand curve.

new firms will be attracted into the industry.

question

The diagram portrays

answer

the equilibrium position of a competitive firm in the long run.

question

question

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

answer

question

answer

question

The demand curve faced by a purely monopolistic seller is

answer

downward sloping, whereas that facing the purely competitive firm is perfectly elastic.

question

The demand curve facing a

answer

purely competitive firm is perfectly elastic, because the purely competitive firm may sell all that it wishes at the equilibrium price.

question

The pure (profit maximizing) monopolist's demand curve is not

answer

perfectly inelastic, because MR is negative when demand is inelastic, so MR = MC < 0
