What is England’s marginal product of labor in cloth and in wine, and what is Portugal’s marginal product of labor in cloth and in wine? Which country has absolute advantage in cloth, and in wine, and why?
Use the formula PW/PC = MPLC/MPLW to compute the no-trade relative price of wine in each country. Which country has comparative advantage in wine, and why?
Graph the production possibilities frontier for the Home country.
What is the no-trade relative price of cars at Home?
Graph the production possibilities frontier for the Foreign country.
What is the no-trade relative price of cars in Foreign?
Using the information provided in Problem 2 regarding Home, in which good does Foreign have a comparative advantage, and why?
Suppose that in the absence of trade, Home consumes nine cars and two TVs, while Foreign consumes two cars and nine TVs. Add the indifference curve for each country to the figures in Problems 2 and 3 Label the production possibilities frontier (PPF), indifference curve (U1), and the no-trade equilibrium consumption and production for each country.
In what good will each country specialize? Briefly explain why.
Graph the new world price line for each country in the figures in Problem 4, and add a new indifference curve (U2) for each country in the trade equilibrium.
Label the exports and imports for each country. How does the amount of Home exports compare with Foreign imports?
Does each country gain from trade? Briefly explain why or why not.
Which country has an absolute advantage in the production of bicycles? Which country has an absolute advantage in the production of snowboards?
What is the opportunity cost of bicycles in terms of snowboards at Home? What is the opportunity cost of bicycles in terms of snowboards in Foreign?
Which product will Home export, and which product does Foreign export? Briefly explain why.
What is the marginal product of labor for TVs and cars in the Home country? What is the no-trade relative price of TVs at Home?
What is the marginal product of labor for TVs and cars in the Foreign country? What is the no-trade relative price of TVs in Foreign?
Suppose the world relative price of TVs in the trade equilibrium is PTV/PC = 1. Which good will each country export? Briefly explain why.
In the trade equilibrium, what is the real wage at Home in terms of cars and in terms of TVs? How do these values compare with the real wage in terms of either good in the no-trade equilibrium?
In the trade equilibrium, what is the real wage in Foreign in terms of TVs and in terms of cars? How do these values compare with the real wage in terms of either good in the no-trade equilibrium?
In the trade equilibrium, do Foreign workers earn more or less than those at Home, measured in terms of their ability to purchase goods? Explain why.
Why do some low-wage countries, such as China, pose a threat to manufacturers in industrial countries, such as the United States, whereas other low-wage countries, such as Haiti, do not?
Answer Problems 9 to 11 using the chapter information for Home and Foreign.
Suppose that the number of workers doubles in Home. What happens to the Home PPF and what happens to the no-trade relative price of wheat?
Suppose that there is technological progress in the wheat industry such that Home can produce more wheat with the same amount of labor. What happens to the Home PPF, and what happens to the relative price of wheat? Describe what would happen if a similar change occurred in the cloth industry.
Using Figure 2-5, show that an increase in the relative price of wheat from its world relative price of will raise Home’s utility.
Using Figure 2-6, show that an increase in the relative price of wheat from its world relative price of will lower Foreign’s utility. What is Foreign’s utility when the world relative price reaches 1, and what happens in Foreign when the world relative price of wheat rises above that level?
From this figure, what is the new world relative price of wheat (at point D)?
Using this new world equilibrium price, draw a new version of the trade equilibrium in Home and in Foreign, and show the production point and consumption point in each country.
Are there gains from trade in both countries? Explain why or why not.
Using the results from Problem 11, explain why the Ricardian model predicts that Mexico would gain more than the United States when the two countries signed the North American Free Trade Agreement, establishing free trade between them.
