Instructions:
·
You have
2 hours to complete this exam.
·
Write
directly on the exam.
·
You may
use any books, notes, or other materials that you wish, but avoid spending too
much time on any one question.
·
Partial credit may be awarded on all
questions.
·
The
maximum possible number of points is 120.
·
You
should have five pages, counting this one.
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 nine propositions is true or false. Using 2-3 sentences AND/OR equations, explain
your answer.
1. In a world with no externalities, suppose the
government imposes a lump sum tax and uses it to fund an hourly work subsidy.
True, False, and
Explain: The deadweight cost of this
tax-and-subsidy policy is zero.
2. Suppose two
people repeatedly play the Dictator game.
Player 1 gets to be the Dictator in odd-numbered turns; Player 2 gets to
be the Dictator in even-numbered turns. β≤1 for both players. After each turn, the game ends with
99% probability.
True, False, and
Explain: An equilibrium where the Dictator always
offers even splits (50/50) may be sustainable if the stakes increase over time.
3. Consider a simple auction.
True, False, and
Explain: As
long as actors have RE, the Winner’s Curse will not cause the market to
“unravel.”
4. “The average person considers himself
better than average by a variety of measures. But vulnerability to such biases
is still far from universal. Robins and John (1997) surprisingly
report
that ‘only
about 35 percent of the subjects show a clear self-enhancement bias whereas
about
50 percent are
relatively accurate and about 15 percent actually show self-diminishment
bias’ (p.
669).” (Caplan, “Stigler-Becker vs. Myers-Briggs”)
True, False, and
Explain: By itself, this result suggests that
self-enhancement bias will affect market outcomes, but not democratic outcomes.
5. Suppose foregone earnings are the sole cost
of education, and people live forever.
Without school, workers earn $10,000 per year; every year of school completed boosts earnings by 10%.
True, False, and
Explain: Without
externalities, the social rate of return to education is 10%.
6. True, False, and Explain: Wittman
admits that in a federal system, restraining government spending is a public
good.
Part 2: Short Answer
(20 points each)
In 4-6 sentences
AND/OR equations, answer each of the following three questions.
1. Historians often argue that wars arise due to
irrationality, not just bad luck. What
simple game theory model are historians implicitly rejecting? How could historians use Thaler’s The Winner’s Curse to persuasively
defend their position? Be specific.
2. “Contrary to
e.g. Krugman, insurance isn't a ‘special’ market where laissez-faire doesn't
work. Instead, it's a normal market where democratic politics doesn't
work, because both the public and economists remain wedded to populism and
paternalism.” (Me on my blog)
Carefully explain why I would say this. Name two examples I might use to support my
position. Am I right? Why or why not?
3. Workers deeply resent nominal wage cuts. Voters deeply resent inflation. Use these two stylized facts to build a
simple, depressing model of the economic and political effects of negative
shocks to Aggregate Demand. Make sure
you discuss the interaction between
economics and politics.
