Chapter 16, Problem 1QCMC

To determine

Relation between money supply and aggregate demand.

Answer to Problem 1QCMC

Option ‘b’ is correct.

Explanation of Solution

Option (b):

By the theory of liquidity preference, an increase in the money supply shifts the money supply curve to the right causing the equilibrium interest rate to decrease. This stimulates consumption and investment, thereby expanding aggregate demand. Thus, option ‘b’ is correct.

Option (a):

Increase in money supply shifts the money supply curve to the right, which lowers the interest rate. Thus, option ‘a’ is incorrect.

Option (c):

By the theory of liquidity preference, a decrease in money supply shifts the money supply curve to the left causing the equilibrium interest rate to increase. This reduces consumption and investment, thereby contracting aggregate demand. Thus, option ‘c’ is incorrect.

Option (d):

Decrease in money supply shifts the money supply curve to the left, which increases the interest rate. Thus, option ‘d’ is incorrect.
