Part 1: True,
False, and Explain
(10 points each - 2
for the right answer, and 8 for the explanation)
State whether each of the following six propositions is true or false. In 2-3 sentences, explain why. Use diagrams if helpful.
1. Suppose the government requires all firms to pay a flat $1000/year license fee.
T, F, and Explain:
Because the market price will
rise, the number of firms that "fit" in the market could either go up
or down.
FALSE. The license raises firms' average costs, but
does not shift demand. Firms will leave
the industry until price rises to equal the new, higher, minimum AC.
2. "On August 19, just before
T, F, and Explain: As this example indicates, one problem with collusion is disagreement about the "division of the spoils."
FALSE. This is an example of the hold-out problem. Ford was not bargaining for an especially good deal from the NACC; he
was refusing to join at all.
3. Suppose large firms are better at lobbying than small firms.
T, F, and Explain:
This would lead to a positive
correlation between concentration and profits.
TRUE. Large firms are more likely to be found in
concentration industries. If large firms
were better at lobbying than small firms, then, firms in concentrated
industries would be more likely to be protected by the government from
competition, leading to a positive correlation.
(Large firms are also more
likely to be market leaders. So assuming
large firms are better at lobbying than small firms, it is ALSO true that there
would be a positive correlation between market share and profits. I gave substantial partial credit for this
answer).
4. T, F, and
Explain: Monopoly problems and
positive externalities problems offset each other.
FALSE. Monopoly problems and negative externalities problems offset each other, because the
former leads to inefficiently low output and the latter leads to inefficiently
high output. Monopoly problems and
positive externalities amplify each other,
because both lead to inefficiently low output.
5. T, F, and
Explain: It is more efficient for a restaurant owner to set up a non-smoking
section than it is for the owner to entirely disallow smoking in his
restaurant.
FALSE. It depends on the number of non-smokers and
smokers, and their respective willingness to pay for the kind of air they want
to breathe. If there are lots of rich
non-smokers who hate the smell of smoke, and a few poor smokers who only like
smoking a little bit, a restaurant owner would want to ban smoking
entirely. On the other hand, if the
numbers are more even and/or smokers are more willing to pay to smoke than
non-smokers are to pay to stop them, smoking sections will be a more efficient
approach.
6. Suppose there were no patents for drugs.
T, F, and Explain: There
would be little effect on R&D because – due to the high fixed costs and low
marginal costs of producing a new drug – the pharmaceutical industry is
naturally monopolistic.
FALSE. Only the innovator has high fixed costs and
low marginal costs; imitators have low
fixed costs and low marginal costs. So
without patents, the imitators would drive price down very low, making it
difficult for innovators to recoup their R&D costs.
Part 2: Short
Answer
(20 points each)
In 4-6 sentences, answer both of the following questions.
1. Suppose the major television networks write a contract with each other, in which they agree to produce less violent programming. Why would economists doubt that programming will actually become less violent? Explain in detail.
This is open collusion to
reduce the supply of violent programming, and will suffer from all the usual
problems. Most obviously, the
anti-violence contract will provoke new entry from other stations. But it will also lead to: (a) cheating – each
firm will try to sneak in more violence to steal viewers; (b) hold-outs – some
firms will refuse to sign; (c) division of spoils – firms will argue about who
cuts back what; (d) quality competition – even if firms keep the agreement,
they will try to improve product quality along other dimensions (for example,
hiring better writers).
2. What effect does antitrust have on innovation? (Hint: Think about "leapfrog" competition). Use Cox and Alm to support your argument.
Cox and Alm argue that a lot
of progress stems from innovative firms putting existing firms out of business
("churn"). But given the
existence of antitrust laws, an innovative firm has to be careful about doing
this. If its new technology or methods
drive all its competitors into bankruptcy, the innovator is likely to be sued
and/or prosecuted by the government. The
result: Firms have an incentive to "pull their punches" – to slow
down the wheels of progress enough to avoid legal attention.
