A. To graph the supply and demand for real money balances, we can plot the money demand function π/π = 1,000 β 100π and the money supply M = 1,000/2 = 500 on a graph with r on the x-axis and π/π on the y-axis.
B. To find the equilibrium interest rate, we set money demand equal to money supply:
1,000 β 100π = 500
100π = 500
π = 5%
Therefore, the equilibrium interest rate is 5%.
C. If the money supply is raised to 1,200, the new money supply would be 1,200/2 = 600. To find the new equilibrium interest rate, we set money demand equal to the new money supply:
1,000 β 100π = 600
100π = 400
π = 4%
Therefore, the equilibrium interest rate would decrease to 4% if the money supply is raised to 1,200.
D. If the Central bank wishes to raise the interest rate to 7%, we can set the money demand function equal to the new interest rate:
1,000 - 100(7) = 1,200
1,000 - 700 = 1,200
300 = 1,200
M = 600
Therefore, the Central bank should set the money supply to 600 in order to achieve an interest rate of 7%.
3. Suppose that the money demand function is(π/π)
π = 1,000 β 100π, where r is the interest
rate in percent. The money supply M is 1,000 and the price level πis 2.
