b. A would likely export S to B
c. Neither country would want to trade
d. Both would like to import B
e. None of the above

possibilities frontier, then production is said to be subject to
a. constant opportunity costs at any production outcome
b. decreasing opportunity costs at any production outcome
c. increasing opportunity costs at any production outcome
d. Decreasing opportunity costs at low production outcome then increasing
opportunity costs at higher outcome
e. none of the above
3. The gains from international trade are closely related to
a. The labor theory of value
b. The fact that the other country must lose from trade
c. How much the autarky price differs from the international price
d. all of the above
e. none of the above
4. The HO model rules out the classical model's basis for trade by assuming
a. Homogenous damand
b. Economics of scale
c. Existence of transaction costs
d. Identical technology
e. All of above
5. Which of the following is true?
a. In the HO model complete specialization in the production of exports is
a likely outcome of international trade
b. International differences in taste, if sufficiently large, could overturn
the comparative advantage predicitons of the HO Model
c. Leontief showed that US exports were capital intensive relative to US
imports.
d. According to the factor price equlization theorem, free international trade
will result in wages equating rents worldwide.
e. Two of the above
6. Country A is labor abundant and B is capital abundant, once trade opens
a. Wages and rents should fall in A
b. The labor factor should opposed free trade policy in A and B
c. Wages should rise and rents should fall in A
d. The gains from trade may be negative in A if wages were too low initially
e. Two of the above
(II) Calculation Questions(22%)
Home has 1800 units of labor available, and Foreign has 1200 units.
They both can produce two goods, apples and bananas. For Home, the unit labor
requirement in apple production is 4, while in bananas it is 3. Foreign's
unit labor requirement in apple produciton is 2, while in bananas is 1
a. Graph the 2 countries' production possibility frontier(2%)
b. Calculate the price of bananas in terms of apple in the 2 countries in the
absence of international trade (2%)
c. Determine the good that Home has comparative advantage, and explain why.(3%)
d. Determine the good that Foreign has comparative advantage, and explain
why.(3%)
e. Construct the world relative supply curve as clearly as possible. (3%)
f. Determine the limit to the relative wage rate. (3%)
g. Show how the 2 countries gain from trade, please graph.(3%)
h. Show the effect on world output if each coutry moved toward specialization
of its comparative disadvantage good. (3%)
(III) Essay Questions (60%)
1. 2 countries: A (labor-abundant) B (capital-abundant)
2 goods: X (labor-intensive) Y (capital-intensive)
a. Explain an export-biased growth for A, and analyze the effects on A's term
of trade if trade exists (7%)
b. Show the effects on the terms of trade if country A makes a transfer of
some of its income to B. (3%)
2. Suppose that at current factor prices cloth is priduced using 24 hours of
labor for each acre of land, and food is produced using only 8 hours of
labor per acre of land.
a. Supposed that the economy's total resources are 720 hours of labor and 48
acres of land. Use a diagram determine the allocation of resouces.(4%)
b. Now suppose that the labor supply increases to 800, draw a diagram to
determine the resources allocation and explain the implication.
3. Country A is land abundant, while country B is labor abundant.
Good X is land intensiverelative to good Y and Y is labor intensive relative
to X.
Graphically demonstrate the pre-and post-trade equilibrium between the two
countries. Find and label the trade triangles for each. Which factors gain
which factors lose when trade arises between the two countries (14%)
4. Explain carefully why the assumption of identical technology worldwide
eliminated the classical basis for international trade.(6%)
5. Explain what is gravity model(4%)
6. In a two-good and two-factor Model:
X be labor-intensive, Y be land-intensive in produciton
Draw a diagram to show the relation between relative goods prices, relative
factor prices and land-labor ratio and please explain clearly. Then express
how trade could cause income redistribution across the two inputs sectors.
And predict which groups should be in favor of or opposed to free
international trade. (16%)
