The following appeared in a Florida newspaper a week after a hurricane hit the state.
"Floridians are relieved that the storm produced no fatalities but homeowners face
weeks, if not months, of rebuilding. Matters are made worse by the soaring prices of
plywood and other building materials that always follow in a hurricane's path.
Complaints of profiteering and price gouging have not deterred firms from raising their
prices by over 100 percent." Which of the following offers the best explanation for the
price increases referred to in the article?
A) The hurricane reduced the number of suppliers of building materials.
B) The hurricane created an artificial shortage of building materials.
C) The hurricane caused an increase in the demand for building materials.
D) There was a reduction in supply as firms shipped plywood and other materials to
locations not affected by the storm.
Wilbur Rickhiser, a financial advisor, recently told one of his clients: "The biggest
mistake you can make is to hold onto a stock for too long in order to avoid a loss. Let's
say you bought a stock for $50 per share but that six months later the price fell to $40
after a poor earnings report. Many of my clients in this situation will hold the stock,
hoping the price will later rise above $50. In most cases like this the price does not rise
and may even fall. You must know when to cut your losses." Which of the following is
the best explanation for Rickhiser's advice?
A) People sometimes buy stocks because other people are buying them or they want to
appear to be fashionable.
B) People sometimes make mistakes when they buy stocks because of the endowment
effect.
C) People sometimes make mistakes when they buy stocks or when they buy goods and
services: they ignore the monetary opportunity costs of their choices.
D) People often fail to ignore the sunk costs of their decisions. The cost of the stock
bought at $50 per share is a sunk cost.

The De Beers Company, one of the longest-lived monopolies, is facing increasing
competition. One source of competition comes from people who might resell their
previously owned diamonds. Why is De Beers worried that people might resell their
previously owned diamonds?

diamonds and fears that its reputation might be harmed

demand for diamonds and dilute De Beers' monopoly

demand curve for diamonds more inelastic and force De Beers to lower its price

Table 14-2
Table 14-2 shows the payoff matrix for Wal-Mart and Target from every combination of
pricing strategies for the popular PlayStation At the start of the game each firm charges
a low price and each earns a profit of $7,000.
Refer to Table 14-2. Is the current strategy in which each firm charges the low price and
earns a profit of $7,000 a Nash equilibrium? If not, why and what is the Nash
equilibrium?

price. The Nash equilibrium occurs when each firm charges the high price and earns a
profit of $10,000.
B) No, the current situation is not a Nash equilibrium; it is a dominant strategy
equilibrium. There is no Nash equilibrium in this game.

firm is to have the other charge a high price and for the firm in question charge a low
price.
