Notice that unless specifically instructed, you will not be
required to use graphs to answer these questions. You may find
it helpful though.
International Trade
1. Suppose that two countries (US and Cuba) conform to the
assumptions of the Heckscher-Ohlin model and initially do not
trade with each other. Only two products are produced—
textiles are labor intensive while steel is capital intensive.
Cuba has relatively more labor than does the US. Labor and
capital are mobile between industries.
A. Explain which products each country should export and
why. [That is, do not just say that Cuba has a comparative
advantage in good X—you must explain why it has a
comparative advantage.]
B. What would be the expected effect of opening trade on
wages and returns to capital in Cuba in the long run? Explain.
2. a. For the policies below, note a small country’s imposition
of the policy will increase (+), decrease (-), or have an
unclear effect (?) on the variables listed vertically. (Please
note, you do not have to explain; just note the direction of
change.) Assume that transfers among domestic citizens have no
effect on welfare.
Tariff Export subsidy Import quota Export tax
Domestic price
Domestic consumer surplus
Domestic producer surplus
Government revenue
Net national welfare

2. If any of the effects are unclear, provide a brief explanation.
b. For each, explain the nature of any deadweight losses in
detail, i.e. compare the costs of domestic production and
consumer benefits with the reduced or expanded trade.
3. Suppose the assumptions of the Ricardian model apply. Let
LA = country A's endowment of labor =100 units; LB = country
B's endowment of labor = 100 units. The unit labor coefficients
for the two countries for good S and C are:
aLc = 2L/c, aLs = 10L/s; bLc = 10L/c, bLs = 1L/s.
a. What is the opportunity cost for C in each country? Provide
specific numbers (i.e. number of S per C).
b. Explain which country has the absolute advantage in each
good.
c. Explain which country as the comparative advantage in each
good.
d. What is the range of potential relative prices for mutually
beneficial trade? Provide specific numbers (i.e. number of C
per S).
e. For one particular possible trading price, show the PPF for
both countries and the relevant post-trade national income
(presuming full specialization).
4. Illustrate and explain how the US (a large country in
international oil markets) can benefit from imposing a tariff on
petroleum. Which group or groups ultimately pay for the tariff?
What are the major drawbacks for a country pursuing this
policy? How would consumers of petroleum in Europe be
affected by the tariff?

3. 5. Illustrate and explain how a Australia (a large country in the
international iron ore markets) can benefit from imposing an
export tax on iron. Which group or groups ultimately pay for
the export tax? What are the major drawbacks for a country
pursuing this policy? How would Chinese steel manufacturers
(who buy iron) be affected by the policy?
6. Suppose that a small country imposes an export tax on its
exported good called autos, which is a capital intensive good.
The other (imported good) is called wheat.
a. Analyze the impact of the export tax on the real returns to
labor and capital in both industries in the short run (i.e. when
labor and capital are immobile across industries). Be sure to
discuss the ability of workers and capital owners in each
industry to buy both goods as a consequence of the export tax.
b. Analyze the impact of the export tax on the real returns to
labor and capital in both industries in the long run (i.e. when
labor and capital are mobile across industries). Be sure to
discuss the ability of workers and capital owners in each
industry to buy both goods as a consequence of the export tax.
c. Using relative prices, show that the export tax (on autos) and
an import tariff (on wheat) will have similar affects on the
production of the two goods in this economy.
7. Suppose that Peru (a small country) is considering two
possible policies to limit imports of Chinese textiles: a tariff
and a quota
a) Using a supply and demand curve graph, analyze the effects
of the tariff on Peruvian consumers, producers, and the
government. Be sure to include the impact on overall national
welfare, assuming that transfers across individuals have no
effect on welfare.
b)Redo part a) for the import quota.
c) Explain how foreigners would be affected for both policies.
8. Suppose that the Trump administration has decided to
impose a 25 percent tariff on Chinese products. Using supply

4. and demand analysis (though not necessarily graphs) for a
single representative product, explain the effect of imposing the
tariffs on the U.S. and Chinese economy. Assume that the U.S.
is a “large” country.
9. Outline the basic principles of the General Agreement on
Trade and Tariffs (now the WTO). What role does
multilateralism and the most-favored-nation (MFN) principle
play in the GATT? Discuss two situations where GATT rules
allow nations to violate the MFN principle.
10. Suppose that a country exports a good called X and imports
a good called Y.
a) Analyze the effects on consumers, producers and the
government if the country imposes an export tax. Assume that
the country is "large" in its export market.
b) Analyze the effects on consumers, producers and the
government if the country imposes an import tax. Assume that
the country is "large" in its import market.
11.
Derive and explain the relationship between a country's
government budget deficit, current account and net private
savings. If domestic investment rises at the same time
government spending increases, how might this be financed? If
the U.S. Congress "outlawed" the current account deficit, use
the relationship derived above to explain why the U.S. would be
forced to increase net government and/or private savings.
13.Suppose that the assumptions of the Heckscher-Ohlin model
apply. Suppose that airplanes are capital-intensive and toys are
labor-intensive. Labor and capital are mobile across industries
but immobile across countries. Furthermore, the capital and
labor endowments for the U.S. and Colombia are: KUS = 200K

5. and LUS = 50L; KC = 10K and LC = 25L
a. Explain which country has a lower relative price for capital
before trade.
b. Explain which country has a comparative advantage in each
good.
c. Explain what will happen to the wage/rental ratios in both
countries if they open to trade.
d. Suppose that labor and capital could move across borders
instead of allowing trade in goods. To which country would
each tend to move? What would happen to the wage-rental
ratio in each country?
International Finance/Macroeconomics
1. Consider a foreign exchange market between the Mexican
peso ($) and the Japanese yen (Y):
a) Illustrate the market equilibrium. Make up a specific
equilibrium exchange rate. Be sure to label the graph carefully
and completely.
b) On a new graph, label a situation where the Mexicans have
an undervalued currency. Are the Mexican running a balance of
payments surplus or deficit? Can you say anything about the
current account in this situation? Explain.
c) How would the Mexican central bank maintain this exchange
rate? Be specific.
2. Suppose that you are told that the interest rates on a US

6. government bond are lower than a comparable German bond
(i.e. equal risk and maturity).
a) Assuming that uncovered interest parity holds (so that
investors are currently indifferent between the two assets), what
would this imply about the market's expectation of the future
value of the dollar in the exchange market? Explain.
b) Can you draw any conclusions about the market's expectation
about inflation in the US and Germany? Explain.
3. Suppose that an investor is deciding between buying a U.S.
bond (which pays out interest in dollars) and a UK bond (which
pays out interest in pounds). The U.S. interest rate is 2% while
the British interest rate is 3%. The current exchange rate is:
$1 = 0.80 pounds. Suppose further that the investor would like
to use the forward market to hedge against exchange rate
movements. What would the forward rate be to make investors
indifferent between these two investments? Would the investor
buy a contract for buying dollars or pounds in the forward
market?
4. Suppose two countries have fixed exchange rates
a) The first has a balance of payments surplus. What can you
surmise about whether the central bank is gaining or losing
official reserves? What economic downsides exist for the
domestic economy if these surpluses continue? Explain.
b) The second has a balance of payments deficit. What can you
surmise about whether the central bank is gaining or losing
official reserves? What economic downsides exist for the
domestic economy if these deficits continue? Explain.
5. Suppose that the Trump administration is considering large
infrastructure projects to increase U.S. economic activity.
Assume further that the U.S. maintains flexible exchange rates.
Analyze the impact of this policy in:

7. a) Keynesian short run model
b) Classical long run model
Assume that financial capital is perfectly mobile. Is there a
difference in the expectations about the effectiveness of the
policy in the two frameworks? Explain.
6. In the immediate aftermath of the Financial Crisis of 2008-9,
the U.S. pursued two policies: a) The Federal Reserve
purchased large amounts of domestic bonds in what was called
“quantitative easing”; b) the Obama administration pushed an
economic stimulus plan that focused on increased government
spending. The U.S. had flexible exchange rates during this
period. Which of these policies would be more likely to be
effective according to Keynesian analysis. .
7. Suppose the assumptions of the Keynesian model apply.
Exchange rates are flexible. Suppose that commercial banks
decide unilaterally to increase the percentage of funds that they
hold in their reserves at the central bank, thereby reducing their
outstanding loans and the amount in currency in circulation.
Analyze the effects of this decision on the exchange change rate
and GNP.
8. Explain the conditions necessary for a group of countries to
be considered an optimal currency area. What would be the
impact if there were a sharp recession in one of the countries?
In particular, how might the two economies adjust to lessen the
differences in economic conditions across the regions.
9. Suppose that you have been recently hired as an outside
economic consultant for a country that has maintained a flexible
exchange rate. Suppose further that past economic policies
have severely restricted the ability of private individuals from
moving financial investment funds into or out of the country.

8. Suppose that the country has just entered a recession and that
two factions within the government have developed competing
plans to revive the moribund economy.
The first faction suggests that the central bank should
immediately purchase bonds on the open market while
simultaneously decreasing domestic income taxes.
The second faction suggests that restrictions on movement of
private capital in and out of the country be eliminated. In
addition, a government program of investment in infrastructure
should be aggressively pursued.
Using Keynesian analysis, explain which, of these two plans is
more likely to increase domestic economic activity. (Consider
only these two policy plans.)
10. Suppose that you have been recently hired as an outside
economic consultant for a country that has maintained a fixed
exchange rate. Suppose further that past economic policies
have severely restricted the ability of private individuals from
moving financial investment funds into or out of the country.
Suppose that the country has just entered a recession and that
two factions within the government have developed competing
plans to revive the moribund economy.
The first faction suggests that the central bank should
immediately purchase bonds on the open market while
simultaneously decreasing domestic income taxes.
The second faction suggests that restrictions on movement of
private capital in and out of the country be eliminated. In
addition, a government program of investment in infrastructure
should be aggressively pursued.
Using Keynesian analysis, explain which of these two plans is

9. more likely to increase domestic economic activity. (Consider
only these two policy plans.)
11. Suppose that a country that maintains a fixed exchange
rate is considering expansionary monetary policy. Analyze the
economic effects of this policy using:
a) the Keynesian framework
b) the classical approach
Be sure to make any necessary assumptions explicit.
12. Explain the effects of a devaluation in
a) the Keynesian framework
b) the classical approach
Be sure to make any necessary assumptions explicit
13. Write a brief essay about the major differences between the
Keynesian model and the neoclassical approach to international
economics. What are the critical assumptions that yield the
different results?
14. Outline the most important arguments for and against
floating and fixed exchange rates. Which set of arguments do
you find more attractive? Explain.
15. Professor Moore saw this sign in the Atlanta airport.
a) What is the implied Euro-dollar exchange rate at the kiosk?
How about the UK – Euro exchange rate?
b) Compare these two exchange rate with that you can find on
the internet (which is typically the amount that banks would pay
for large transactions)?
c) How much profit does the money changer in the airport make
if a U.S. tourist sells $100 for pounds and $100 for euros?

10. 1. What is the production possibilities curve and how is it
useful?
2. What 4 factors contribute to determining any point in this
model?
3. How would we apply this framework to the real world?
4. You are planning to expand your burgeoning business of Bill
Murray themed athletic shoes that were prominently featured in
the Life Aquatic with Steve Zissou (which happens to be the
greatest movie of all time), and you need to determine your cost
structure to ensure that you price your products properly. Rent
on the new production facility is 5,000 per month. Insurance is
6,000 annually. Each T-shirt costs you 5.00 and an additional
3.00 for materials. You purchase your T-shirts by the pallet,
which contains 1,000 in each. However, if you purchase 2
pallets of T-shirts at a time, then you get a 10% discount. If
you purchase 2 pallets of T-shirts, then you get a 20% discount.
Construct a table of your monthly costs reflecting fixed and
variable costs. Be sure to pay very careful attention to the
details…

5. Ride hailing services utilize a dynamic pricing model. Using
supply and demand tools (you don’t have to actually show the
graphs… but they may help you on scratch paper) illustrate how
microeconomics explains the shifts in pricing and how it
describes the real world scenarios of trying to get a ride at
various times of the day. Be sure to consider the morning and
evening commute, in addition to the weekend hours.
6. Disney World has doubled their ticket prices at their
amusement parks over the last 10 years, which of the economic

take into account that competitor parks are nearby. Be sure to

12. detail how this model works and why it fits the Disney World
situation.
