Ungraded Problem Set 3

Question 1

Consider the following information about the nation Suburbia Autarky Free-Trade Production of good X 100 units 200 units Consumption of good X 100 units 100 units Capital used to produce good X 100 units 150 units Labor used to produce good X 100 days 125 days Production of good Y 100 units 50 units Consumption of good Y 100 units 200 units Capital used to produce good Y 150 units 100 units Labor used to produce good Y 50 days 25 days

a) Is Suburbia a labor- or a capital-abundant country? Explain your answer.

b) What is the price of X in terms of Y with free trade?

c) How many units of what product are exported? How many units of what product are imported?

d) Has the marginal product of labor in good X production increased or decreased as a result of trade?  Explain your answer.

e)  Has the marginal product of capital in good Y production increased or decreased as a result of trade?   Explain your answer.

Question 2

Country H Before and After Trade Equilibria

Assume that shoes are a labor-intensive good, and computers are capital-intensive. When H trades, it is with country F. Use the graph above to answer the following.

a) What was the pre-trade consumption/production of shoes and computers?

b) Describe the trade flows between Countries H and F.

c) What is the price ratio (Pc/Ps) at which free trade occurs?

d) Compared to Country H, Country F is relatively _______ abundant and has a comparative advantage in producing _____.

e) What happens to wages in Country H after trade?  Briefly justify your answer.

3.	Suppose that Home has 20% of the world's capital, 10% of the world's skilled labor,  30% of the world's unskilled labor, and produces 20% of the world's GDP. What does this information suggest about Home's resource endowments?  Explain your answer.

4.	According to the Stolper-Samuelson theorem, would you expect U.S. skilled workers to benefit from free trade worldwide?  Briefly explain your answer.

5.	According to the Stolper-Samuelson theorem, would you expect all workers across the globe to favor limiting trade? Why or why not?

6.

If Malaysia has a comparative advantage in producing low-skilled, labor-intensive goods, what should happen to Malaysian low-skilled workers' wages as trade barriers against Malaysian imports fall across the world?  What should happen to returns to capital in Malaysia?  Briefly explain why using what you’ve learned in lecture.

7. Changing K/L ratios.

a) Draw an Edgeworth Box for country H where the production of X and Y utilize Capital (K) and Labor (L).  Let X be the capital-intensive good, and Y be the labor intensive good.  Sketch in an appropriate looking efficiency locus curve and identify two points along the curve, labeled A₁ and A₂, with A₁ being the one closer to the origin for good X.  You need not include isosquant curves.

b) Draw in lines representing K/L ratios for each industry at the points A₁ and A₂. This will be four lines total, label them k_x,1, k_x,2, k_y,1, k_y,2.

c) Suppose the economy starts at point A₁.  It then shifts production to A₂.  What change in world conditions could prompt such a change?

d) How have the K/L ratios changed in each industry?

e) Both industries X and Y have seen their K/L ratios change in the same direction.  Yet, the overall K/L ratio is unchanged in the economy.  Explain how this is possible.
