Which of the following is not a characteristic of a monopolistically competitive market structure?
Each firm must react to actions of other firms.
A monopolistically competitive industry that earns economic profits in the short run will
experience the entry of new rival firms into the industry in the long run.
The study of how people make decisions in situations where attaining their goals depends on their interactions with others is called
game theory.
If Panera Bread's "clean food" strategy succeeds and customers are willing to pay higher prices for their menu items, the company will
likely attract competitors that offer the same kind of food, and all else equal, eventually economic profits will be competed away.
A perfectly competitive firm produces 3,000 units of a good at a total cost of $36,000. The price of each good is $10. Calculate the firm's short-run profit or loss.
loss of $6,000
A monopolistically competitive firm faces a downward-sloping demand curve because
of product differentiation.
Interdependence of firms is most common in
oligopolistic industries.
Refer to Figure 12-2. What is the amount of profit if the firm produces Q2 units?
It is equal to the vertical distance c to g.

Pure monopoly refers to
a single firm producing a product for which there are no close substitutes.

buyer responsiveness to price changes.
The demand for a product is inelastic with respect to price if
consumers are largely unresponsive to a per unit price change.
To maximize their profits and defend those profits from competitors, monopolistically competitive firms must
differentiate their products.

duopoly.

travel agencies

8 units of utility

Refer to Figure 14-2. If the government delays Gigacom's entry and Xenophone moves first, what is the likely outcome in the market?
Both offer DSL internet service; Xenophone earns a profit of $8 million and Gigacom earns a profit of $7 million.
Refer to Figure 14-2. Now suppose that the government delays Xenophone's entry and Gigacom moves first, what is the likely outcome in the market?

Profit is the difference between
total revenue and total cost.
The five competitive forces model was developed by
Michael Porter.
Refer to Figure 14-2. If the government delays Gigacom's entry and Xenophone moves first, is a threat by Gigacom that it will provide DSL service if Xenophone provides cable service a credible threat?
No, because Gigacom will lose $4.5 million in profits if it carries out its threat.
Refer to Table 14-1. Is there a dominant strategy for AirPorter and if so, what is it?
No, its outcome depends on what LimoZeenz does.

products are differentiated.
A Nash equilibrium is
reached when each player chooses the best strategy for himself, given the other strategies chosen by the other players in the group.
When plasma television sets were first introduced prices were high and few firms were in the market. Later, economic profits attracted new firms and the price of plasma televisions fell. This example illustrates
that consumers receive this new technology "free of charge" in the sense that they only have to pay a price for plasma televisions equal to the lowest production cost.
