Exam 9: Firms in Perfectly Competitive Markets

If a monopolistically competitive firm is producing 50 units of output where marginal cost equals marginal revenue,total cost is $1674 and total revenue is $2000,its average profit is

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.

Figure 9-9 -Refer to Figure 9-9.Which of the graphs in the figure depicts a monopolistically competitive firm that is minimising its losses?

Because many business situations are repeated games,firms may be able to avoid the prisoner's dilemma and implicitly collude to keep prices high.

Consumers benefit from monopolistic competition by

Which of the following is not part of an oligopolist's business strategy?

An oligopolistic industry is characterised by all of the following except

Figure 9-8 Figure 9-8 shows cost and demand curves for a monopolistically competitive producer of iced tea. -Refer to Figure 9-8.What is the firm's profit-maximising price?

Producing a homogeneous product occurs in which of the following industries?

Figure 9-12 -Refer to Figure 9-12.What is the monopolistic competitor's profit-maximising output?

A monopolistically competitive firm faces a downward-sloping demand curve because

Table 9-3 Table 9-3 shows the demand and cost schedules for a monopolistically competitive firm. -Refer to Table 9-3.What is the best course of action for the firm in the short run?

In the long run,if the demand curve of a monopolistically competitive firm is tangent to its average total cost curve,then

Suppose a monopolistically competitive firm sells 25 units at a price of $10.Calculate its marginal revenue per unit of output if it sells 5 more units of output when it reduces its price to $9.

If economies of scale are significant,the typical firm will not reach the minimum point on its long-run average cost curve until it has produced a large fraction of industry sales.

In economics,the study of the decisions of firms in industries where the profits of each firm depend on its interactions with other firms is called

One reason why,in the last four decades,the number of new auto makers in the world has been very small compared to the past is that

We can draw demand curves for firms in perfectly competitive and monopolistically competitive industries,but not for oligopoly firms.The reason for this is

Each member of OPEC can increase its income by selling more oil than its output quota because

Which of the following is not a characteristic of oligopoly?
