Document Summary

Please b) c) specify whether money demand increases or decreases, and explain briefly. As people income decreases, the volume of their transactions decreases because they do not have as much money to allow for purchases of goods and services (money as a medium of exchange), which decreases the demand for money. Illustrate the effect of this event using the money market graph. Due to a decrease in money demand, the value of money will decrease, increasing the price level. Using the quantity theory equation mv = py, we have: (% change in m) + (% change in v) = (% change in p) + (% change in y) => (% change in m) + (% change in v) = (inflation) + (% change in y) Since v is constant, % change in v is 0, moving % change in m to one side: => (% change in m) = (inflation) + (% change in y)

the number of goods and services demanded. (Circle the correct answer for each.)

the money supply, which would (decrease, increase) the interest rate.

(Circle the correct answer for each.)

interest rate causing the aggregate demand curve to shift (in, out).

Question 4. (0.7 pt) The Federal Reserve contracts the money supply by 5 percent.

(Make sure to label your axes.)

 

a. ) Use the supply of money and the demand for money diagram to illustrate the impact of this policy on the interest rate.

c. A decrease in the reserve requirement decreases the money supply because banks have fewer reserves.

d. The real money demand curve shows how households and businesses change their spending in response to changes in the interest rate.

e. Both an increase in the nominal money supply by the Federal Reserve and an increase in the price level will cause the real money supply curve to shift to the right.
