Problem Set 3
Do all problems:
1. (30) Answer true or false and why. Write no more than one paragraph for each question.. .
a. Offshoring work reduces national income.
b. There is never a secondary burden of a transfer since the decrease in our consumption isexactly matched by the increase in theirs.
c. Growth in an economy can never hurt it as it moves its PPF outwards allowing them to havemore of all goods.
2. (40) Assume the following fixed coefficient technology.
Good/Factor Unit Labor Requirement Unit Capital Requirement
Clothing 10 20
Food 20 10
Assume there are 100 units of labor and 100 of capital at home and that the price of food equals that of clothing which equals 1.
Below draw the answers to the question for the example on the left and for the general model on the right hand side so you can see them side by side.
i. Depict the Production Possibility Frontier (PPF) for the economy. Assuming the economymakes both goods and imports food, depict the equilibrium under free trade in a diagram. In the answer sheet above put how much of each good is made in equilibrium.
ii. For given product prices, explain how factor prices are determined. If the price of food rises,but there is incomplete specialization, what happens to real wages and to the real return to capital. In the answer sheet above fill in the blanks on how factor prices change. iii. For given product prices, and assuming no specialization, explain how the PPF is affected and how the equilibrium output changes as capital stock rises. In the answer sheet above fill in the blanks on how output changes.
2. (30) Israel, which is a small open economy (so that world prices can be assumed fixed for it) had a huge inflow of skilled labor after the breakup of the former Soviet Union. Population rose by 11% and labor force by 14%, mostly of skilled labor. Israel makes software which is skilled labor intensive, and oranges, which are unskilled labor intensive. These are the only two factors of production.
One might be inclined to argue that this must have reduced the wage of skilled labor as skillled labor supply shifted out, but demand was unchanged.
a. However, evidence on wages shows no such tendency. How can you explain this in theabsence of technical change? Did the demand for skilled labor shift out to keep wages the same? Why? (Hint: Use the Rybczynski Theorem.)
