18. If resources A and B are complementary (not substitutes) in the production of whoppers and employed in fixed proportions:
A) a change in the price of A will have no effect on the quantity of B employed.

C) an increase in the price of A will increase the demand for B.
D) an increase in the price of A will decrease the demand for B.

19. Suppose capital and labor are used in fixed proportions so that each machine requires only one worker, and they are substitutes. If a decline in the price of capital occurs, then the demand for labor will:

B) increase solely because of the substitution effect; that is, there is no output effect.
C) decline because of the substitution effect and increase because of the output effect.
D) decrease solely because of the output effect; that is, there is no substitution effect.

20. Assuming a competitive resource market, a firm is hiring several resources in the profit-maximizing amounts when the:

25. The equilibrium interest rate equates:
A) nominal and real interest rates.
B) the quantities demanded and supplied of money available for loans, or "loanable funds."
C) consumption and saving.
D) interest rates on Treasury bills and government spending.

26. Read carefully. The supply (not demand) curve of money available for loans is upsloping because:

B) banks lend more at high interest rates than they do at low interest rates.
C) government budget deficits vary inversely with the equilibrium interest rate.
D) banks lend more at low interest rates than they do at high interest rates.

27. The equilibrium interest rate:
A) allocates the available supply of loanable funds to investment projects that have high enough rates of return to justify the borrowing.
B) rises when the supply of loanable funds increases.
C) is the price paid for the use of any resource.
