Table 14-7 The payoff matrix shown above assumes that Perfect Plants and Florabunda Florist must decide whether to offer same-day delivery for their products.

Refer to Table 14-7. Which of the following statements is true?
Given that Perfect offers same-day delivery, Florabunda's best strategy is to offer same-day delivery.

In the second industry, firms always ignore price changes by any other firm. which of the following statements is true about these two industries, holding everything else constant?
Market prices are likely to be higher in the first industry in which firms always match price changes by rival firms than in the second where firms ignore their rivals' price changes.

They would be more profitable if they refrained from advertising but each fears that if it does not advertise, it will lose customers.

A patent is an example of
a government-imposed barrier to entry.
Why does a prisoner's dilemma lead to a noncooperative equilibrium?
because each rational player has a dominant strategy to play a certain way regardless of what other players do
A market comprised of only two firms is called a
duopoly.
Of all barriers to entry, the most important are those that are due to
economies of scale.
Economists use game theory to analyze oligopolies because
game theory helps us to understand why interactions among firms are crucial in determining profitable business strategies.
All of the following are characteristics of game theory except
independence among players
Hewlett-Packard will not raise the prices of its personal computers without first considering how Dell might respond. This is evidence of
interdependence.
In an oligopoly market
one firm's pricing decision affects all the other firms.
For many years the Aluminum Company of America (Alcoa) controlled most of the world's supply of high quality bauxite, the ore needed to produce aluminum. What type of entry barrier was responsible for Alcoa's position in the aluminum industry?
ownership of a key input
All of the following are examples of oligopolistic markets except
seafood restaurant chains
A key part of Microsoft's business strategy in the video game console market has been
