Explain why member firms of a cartel like OPEC have incentives to agree to a low cartel production level and then produce more than its quota.

A low cartel production level results in a high market price for oil. Thereafter, each firm has an incentive to unilaterally cheat on the agreement by producing beyond its quota. Of course, ultimately if everyone cheats then the price of oil will fall, but at least for a while some members will earn higher profits than they would if they had adhered to their quotas.

Why do economists refer to the pricing strategies of oligopoly firms as a prisoner's dilemma game?

A prisoners' dilemma is a game in which pursuing dominant strategies results in a noncooperative equilibrium that leaves everyone worse off than they would be if they could achieve the cooperative equilibrium. The outcome of noncooperative pricing (competition, in other words) will leave firms worse off than if they cooperated and set higher prices.

What is a production possibilities frontier? What do points along the frontier represent? What do points inside and outside the frontier represent?

A production possibility frontier is a curve showing the maximum attainable combinations of two goods that can be produced with available resources and current technology.

What is meant by "excess capacity"? How does it relate to consumer utility?

Excess capacity refers to a situation where a firm does not produce at the lowest possible average cost. In other words, economies of scale have not been exhausted. Excess capacity is an inevitable consequence of product differentiation. Firms differentiate their products in order to appeal to consumers' varied tastes. Consumers are, therefore, better off - they have greater utility - than they would be if companies did not differentiate their products. Consumers are willing to pay for the higher costs that result from product differentiation.

28) What is meant by the term "free market"?

Free market is a market with few government restrictions on how a good or service can be produced or sold or on how a factor of production can be employed.

What is meant by the term "government-imposed barrier to entry"? Why would a government be willing to impose barriers to entering an industry?

Government-imposed barriers to entry are government-issued restrictions which keep new firms from entering an industry. One reason governments are willing to erect barriers to entering an industry is that these barriers may improve the standard of living in the long run; for example, granting patents encourages the development of new products and technologies. Another reason is that firms do favors for politicians who enact such provisions (for example, contributing to campaigns).

Explain why OPEC is caught in a prisoner's dilemma?

If every member of OPEC cooperates and produces the low output level dictated by its quota, prices will be high, and the cartel will earn large profits. Once the price has been driven up, however, each member has an incentive to stop cooperating and to earn even higher profits by increasing output beyond its quota. Thus, it is rational for an individual member to unilaterally increase output to maximize its earnings. But if no country sticks to its quota, total oil output will increase, and collective profits will decline.

The breakfast cereal industry has a four-firm concentration ratio of 80 percent. Is this enough information to classify the industry as an oligopoly? Is a high concentration ratio evidence that an industry is not competitive?

It would be considered an oligopoly. If they were to account for 40% or less it would be monopolistic

The breakfast cereal industry has a four-firm concentration ratio of 80 percent. Is this enough information to classify the industry as an oligopoly? Is a high concentration ratio evidence that an industry is not competitive?

Most economists classify an industry with a four-firm concentration ratio greater than 40 percent as an oligopoly; therefore, the breakfast cereal industry would be considered an oligopoly. But the concentration ratio is a flawed measure of the extent of competition in the breakfast cereal industry. For example, concentration ratios do not include sales in the United States by foreign firms, so to the extent that foreign firms sell breakfast cereal in the United States, the concentration ratio understates the degree of competition in this industry. Also, since concentration ratios are calculated for the national market, regional or local competition is ignored. Concentration ratios are useful for providing a general idea of the extent of competition in an industry.

What is opportunity cost?

Opportunity cost refers to the highest-valued alternative that must be given up to engage in an activity. For example, the opportunity cost of taking this economics class is what you are giving up to take the class, which may be taking another class such as accounting or psychology, working extra hours at your job, or extra sleep (whichever is your highest-valued alternative).

Define productive efficiency. Does productive efficiency imply allocative efficiency? Explain.

Productivity efficiency is a situation in which a good or service is produced at the lowest possible cost. Yes, allocative efficiency is a state of the economy in which production is in accordance with consumer preferences; every good or service is produced up to the point where the last unit provides a marginal benefit to society equal to the marginal cost of producing it.

What is meant by the statement that "optimal decisions are made at the margin"?

The idea of margin is related to making decisions while thinking about the benefits and costs of small changes in behavior.

Deadweight loss refers to the reduction in economic surplus resulting from a market not being in competitive equilibrium. (T/F)

Explain whether the information in this table contradicts the law of one price.

Unless there are big differences in the quality of the retailers in terms of shipping, delivery, or ease of use of their Web sites, these data would seem to contradict the law of one price.

Both the perfectly competitive firm and the monopolistically competitive firm produce at the output where marginal revenue equals marginal cost (MR = MC) but only the perfectly competitive firm achieves allocative efficiency. Explain why this is the case.

Unlike the perfectly competitive firm, the monopolistically competitive firm faces a downward sloping demand curve which means that the firm must lower its price to sell additional units of output. As a result, price will always be greater than marginal revenue (P > MR). By contrast, the perfectly competitive firm faces a horizontal demand curve and P = MR. The profit-maximizing rule, MR = MC, applies to all firms but because in perfect competition P = MR the rule can be written as P = MC. A firm achieves allocative efficiency if it charges a price equals to the MC of producing the last unit. This condition is satisfied at the profit-maximizing output for the perfectly competitive firm (since P = MC = MR) but will not hold for the profit maximizing output of monopolistically competitive firm for which P > MR = MC.

Are restaurant coupons a form of price discrimination? Why or why not?

Yes, coupons are a form of price discrimination. People who are willing to take the time to clip coupons have a higher price elasticity of demand than people who are not. Coupons are a way for firms to cut the price paid by higher price elasticity consumers — without having to cut the price for everyone else.

What is yield management? How is yield management being used in the airline industry?

Yield management is the use of sophisticated models of demand and pricing strategies to maximize revenue and profits. Yield management is used in the airline industry when airlines vary ticket prices based on the season, length of route, day of the week, time of day, and type of passengers on the flight.
