1. (10 Points). In any international trade agreement, the
nation with the comparative advantage will get the best terms. Explain
whether you agree or disagree with the statement.
2. (10 points). A bright young MBA
student who has a lifetime utility function of the form
U = log(c1)+
log (c2) + log(c3) +log(c4)
will, in period 1 of his life consume
(All of the
above is true). He expects to earn
$60,000 in period 2, $360,000 in period 3 and then retire. (All of the above is true). The discount rate is 50% per period. Baring surprises, he will consume $25,000 in
the first period of life.
Explain
whether you agree or disagree with this statement. Hint:
disagree, and give me the right number.
3. (10 points). Y=AK(1-b)Nb. Explain why you agree or disagree with this
statement.
4. (20 points). West Backwater is typical of
many poor countries, characterized by corruption, illiteracy, massive poverty,
high mortality rates, high birth rates, a long running civil war, a high Gini coefficient, and economic power concentrated in a few
wealthy families to name only a few problems.
Fortunately a charismatic leader has assumed power. He has turned to you for advice on
reorganizing the economy to improve economic conditions.
Here is the
good only good news about West Backwater:
he is sufficiently charismatic that he can persuade people to go along
with any program you propose.
What would
you propose? Explain your reasons, for
you must persuade the leader before he will persuade others.
5 (20 points). Daffy Duck has been working 35 hours
a week at $10 an hour, a wage rate he has been receiving for some time and that
he expects to receive for t he foreseeable future. 20% of Daffy’s
wages go to taxes. A new tax law cuts Daffy’s tax rate to 10% for the coming year, but only for
the coming year. What will happen to the
number of hours Daffy works?
Suppose now
that, at the end of the year, in a surprise move, the tax cut is made
permanent. What will happen to the hours
Daffy works.
A couple of
hints: there is an old proverb that a well-labeled and well-explained graph is
worth a thousand words. I fully expect a
graph or two on this answer. Note that
you cannot tell me (I do not think) that Daffy’s
hours will go up (or down) by 2 hours a week.
Tell me as much as you can.
