Alan Krueger conducted a survey of fans at the 2001 Super Bowl who purchased
tickets to the game for $325 or $400. Krueger found that (1) 94 percent of those
surveyed would not have paid $3,000 for their tickets, and (2) 92 percent of those
surveyed would not have sold their ticket for $3,000. These results are an example of
the fallacy of composition.

Assume that the four-firm concentration ratio in an industry is 0.85. Which of the
following statements uses one of the five competitive forces to argue that this industry
may be more competitive than its concentration ratio suggests?
If high concentration is the result of large firms owning much of the available
supply of a key input, the industry will become more competitive when new
sources of the input are discovered by other firms.
The threat of entry into this industry can cause firms in the industry to lower their
prices and profits in order to deter entry.
The high concentration may be due to patents owned by the largest firms but
competition will increase when patent right expire.
Even though concentration is high, large firms in the industry may act
competitively by spending large sums on advertising.
For years economists believed that market structure explained the ability of some firms
to earn economic profits. For instance, firms in industries with little competition and
high barriers to entry would earn higher profits than firms in competitive industries
with low entry barriers. Which of the following has caused economists to question this
explanation and seek other explanations for why firms are profitable?
In recent years new technologies have increased the potential entry of new firms in
industries with high entry barriers.
The market structure explanation fails to explain how firms in the same industry
can have very different levels of profit.
Studies have shown that firms in industries that have little competition and high
entry barriers are not very profitable. Economists conclude from this that some
competition is necessary in order to force firms to lower their costs and develop
products that satisfy new consumer demands.
Studies have shown that, on average, firms in competitive industries earn higher
profit rates that firms in industries with little competition.
