Use your basic knowledge and your understanding of market structures to answer this question. Which of the following companies most closely approximates a differentiated oligopolist in a highly concentrated industry?

ford motor company

The copper, aluminum, cement, and industrial alcohol industries are examples of

homogeneous oligopoly

Prices are likely to be least flexible

in oligopoly

Suppose an oligopolistic producer assumes its rivals will ignore a price increase but match a price cut. In this case the firm perceives its

demand curve as kinked, being steeper below the going price than above.

The mutual interdependence that characterizes oligopoly arises because

each firm in an oligopoly depends on its own pricing strategy and that of its rivals

Refer to the diagram, where the numerical data show profits in millions of dollars. Beta's profits are shown in the northeast corner and Alpha's profits in the southwest corner of each cell. If both firms follow a high-price policy,

each will realize a $20mil profit

Oligopolistic firms engage in collusion to

earn greater profits

As a general rule, oligopoly exists when the four-firm concentration ratio

is 40 percent or more

Game theory

is the analysis of how people (or firms) behave in strategic situations.

Oligopoly is more difficult to analyze than other market models because

of mutual interdependence and the fact that oligopoly outcomes are less certain than in other market models.

Differentiated oligopoly exists where a small number of firms are

producing goods that differ in terms of quality and design.

Interindustry competition means that

in some markets, the producers of a particular product might face competition from products produced by other industries.

In the United States cartels are

in violation of the anti-trust laws

Cartels are difficult to maintain in the long run because

individual members may find it profitable to cheat on agreements.

The term oligopoly indicates

a few firms producing either a differentiated or a homogeneous product.

If there are significant economies of scale in an industry, then

a firm that is large may be able to produce at a lower unit cost than can a small firm.

Refer to the diagram, where the numerical data show profits in millions of dollars. Beta's profits are shown in the northeast corner and Alpha's profits in the southwest corner of each cell. If Beta commits to a high-price policy, Alpha will gain the largest profit by

adopting a low-price policy

OPEC provides an example of

an international cartel

The kinked-demand curve of an oligopolist is based on the assumption that

competitors will follow a price cut but ignore a price increase.

Refer to the diagram, where the numerical data show profits in millions of dollars. Beta's profits are shown in the northeast corner and Alpha's profits in the southwest corner of each cell. Which cell represents a Nash equilibrium?

cell d

Concentration ratios

may understate the degree of competition because they ignore imported products.

Which of the following is a unique feature of oligopoly?

mutual interdependance

Suppose that a particular industry has a four-firm concentration ratio of 85 and a Herfindahl index of 3,000. Most likely, this industry would achieve

neither productive efficiency nor allocative efficiency.
