PROBLEMS

  1. At the beginning of the chapter, there is a brief quotation from David Ricardo; here is a longer version of what Ricardo wrote:
    England may be so circumstanced, that to produce the cloth may require the labour of 100 men for one year; and if she attempted to make the wine, it might require the labour of 120 men for the same time…. To produce the wine in Portugal, might require only the labour of 80 men for one year, and to produce the cloth in the same country, might require the labour of 90 men for the same time. It would therefore be advantageous for her to export wine in exchange for cloth. This exchange might even take place, notwithstanding that the commodity imported by Portugal could be produced there with less labour than in England.
    Suppose that the amount of labor Ricardo describes can produce 1,000 yards of cloth or 1,000 bottles of wine, in either country. Then answer the following:

      Prob 2 10b. 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?
  1. (This is a harder question.) Suppose that the Home country is much larger than the Foreign country. For example, suppose we double the number of workers at Home from 25 to 50. Then Home is willing to export up to 100 bushels of wheat at its no-trade price of PW/PC = rather than 50 bushels of wheat as shown in Figure 2-11. In the following, we draw a new version of Figure 2-11, with the larger Home country.
