In this question, we use the Rybczynski theorem to review the derivation of the Heckscher–Ohlin theorem.

a. Start at the no-trade equilibrium point A on the Home PPF in Figure 4-2, panel (a). Suppose that through immigration, the amount of labor in Home grows. Draw the new PPF, and label the point B where production would occur with the same prices for goods. 

b. Suppose that the only difference between Foreign and Home is that Foreign has more labor. Otherwise, the technologies used to produce each good are the same across countries. Then how does the Foreign PPF compare with the new Home PPF (including immigration) that you drew in part (a)? Is point B the no-trade equilibrium in Foreign? Explain why or why not.

c. Illustrate a new point A* that is the no-trade equilibrium in Foreign. How do the relative no-trade prices of computers compare in Home and Foreign? Therefore, what will be the pattern of trade between the countries, and why?
