Answer:
What is the Value of Bank Deposits?
bank deposits = bank reserves / required reserve ratio = $200 / 20% = $1,000
What is the Money Supply?
money supply = bank deposits + currency held by the public = $1,000 + $1,00 = $2,000
Suppose that the Fed sells $50 worth of bonds in an "open market sale." Assuming that the public does not wish to change the amount of currency it holds, what is the new money supply after this open market purchase?
if the FED sells $50 worth of bonds, money supply will decrease by $50 x (1 / 20%) = $50 x 5 = $250
total money supply = $2,000 - $250 = $1,750
