18. Economic theory suggests that frictional unemployment would
a. decrease if methods of communicating job information among unemployed workers were improved.
b. increase if mothods of communicating job information among unemployed workers were improved.
c. decrease if the legally established minimum wage were increased.
d. decrease if unemployment benefits were increased.
19. The type of unemployment that occurs because of a recession is called
a. frictional unemployment.
b. seasonal unemployment.
c. natural unemployment.
d. cyclical unemployment.
20. Observe the following figure in which the aggregate production function of United States shifts from F1 to F2:
Which of the following could cause such a shift in the aggregate production function?
a. A decrease in the workday from 8 to 7 hours.
b. A less intensive use of installed capacity (less use of capital).
c. An decrease in the price of oil assuming that the US is a net importer of oil.
d. A subsidy per worker hired in the software industry.
21. Suppose that the government is currently running a big deficit and that it wants to close the gap between its revenues and expenditures. In order to reduce the deficit, the Government decides to cut subsidies that are applied to rural producers. In this situation we can observe
a. no shift of either the demand or supply curve.
b. a shift of the supply of loanable funds curve to the left.
c. a shift of the demand of loanable funds curve to the left.
d. a shift of the demand of loanable funds curve to the right.
Use the following Model to answer the next two questions:
Y=C + Sp + T - TR
Sg = T - TR - G
NS = Sp + Sg
NS = Y - C - G
KI = M - X
Y = C + I + G + (X - M)
In equilibrium, leakages=injections
Where Y = real GDP
C = consumption spending
Sp = private saving
T = taxes
TR = transfers
T - TR = net taxes
Sg = government saving
G = government spending
KI = capital inflows
M = Imports
X = exports
I = Investment
Furthermore, suppose the government runs a balanced budget (that is, G - T + TR = 0) and collects $300 in tax revenue. Firms spend $55 on new capital and capital inflow equals $15. Income equals $450 and $220 of that income is spent on consumption. Furthermore, leakages equal injections in this economy.
22. What is the level of private saving in this economy?
a. $55 since private saving must equal investment in order for the loanable funds market to be in equilibrium.
b. $70 since businesses are spending $55 of their own money plus $15 provided via the foreign sector (i.e., capital inflows).
c. $40 since businesses are demanding $55 worth of loanable funds and the foreign sector is supplying only $15 worth of loanable funds.
d. $25 since the total demand for loanable funds is $40 and there are $15 of loanable funds being supplied through capital inflows.
23. What is the level of government transfers in this economy?
a. $0
b. $90
c. $110
d. $125
24. Binding minimum wages generally lead to:
a. cyclical unemployment since not everyone can find a job at the minimum wage rate.
b. frictional unemployment since the binding minimum wage results in longer job searches.
c. strucutural unemployment since more people want to work than can find jobs at the minimum wage.
d. all of the above answers are correct.
Use the following information to answer the next two questions:
Consider the market for loanable funds in a closed economy. The business demand for funds is given by r = 12 - (1/2)I , where I is investment (measured in millions of dollars) and r is the interest rate (measured as a percentage).
The private savings function is: r = Sp, where Sp is private savings (measured in millions of dollars).
Assume that the government's deficit changes from $0 to $6 million. (Note: deficit = G - (T - Tr))
25. How much business investment is crowded out as a result of this increase in government deficit?
a. $0
b. $2 million
c. $4 million
d. $6 million
26. How much does consumption change?

b. increase by $4 million
c. decrease by $4 million
d. can't determine
27. If there in an increase in exports holding everything else constant, the equilibrium interest rate in the loanable funds market will
a. fall.
b. rise.
c. no change.
d. be indeterminate.
28. There are 100 households in the economy. Half of these households save according to r = 2 + Sp/10 while the other half of the households save according to r = 5 + Sp/5 where each of these equations expresses the saving function for one household. What is the market private savings function?
a. r = 2 + Sp/500 for 2 < r < 5 and r = 5 + Sp/250 for r > 5
b. r = 2 + Sp/500 for 2 < r < 5 and r = 3 + Sp/750 for r > 5
c. r = 100 + 5Sp for 2 < r < 5 and r = 250 + 10Sp for r > 5
d. r = 3.5 + 3Sp/500
