1 answer

A. To graph the supply and demand for real money balances, we can plot the money demand function 𝑀/𝑃 = 1,000 βˆ’ 100π‘Ÿ and the money supply M = 1,000/2 = 500 on a graph with r on the x-axis and 𝑀/𝑃 on the y-axis.

B. To find the equilibrium interest rate, we set money demand equal to money supply:
1,000 βˆ’ 100π‘Ÿ = 500
100π‘Ÿ = 500
π‘Ÿ = 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 βˆ’ 100π‘Ÿ = 600
100π‘Ÿ = 400
π‘Ÿ = 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%.
