An economy has a monetary base of 1,000 $1 bills. Calculate the money supply in scenarios a - d. Then answer part e. a. All money is held as currency Money supply = $ b. All money is held as demand deposits. Banks are required to hold 100% of deposits as reserves. Money supply = $ c. All money is held as demand deposits. Banks hold 20% of deposits as reserves. Money supply = $ d. People hold equal amounts of currency and demand deposits. Banks hold 20% of deposits as reserves. Round to the nearest dollar. Money supply = $ e. The central bank decides it should increase the money supply by 10%. By how much should it increase the monetary base to accomplish this goal in each scenario? Monetary base increase = $

b. If all money is in banks but the banks are not loaning it out as they are keeping it in reserves, no loans will be created. Supply is still $1,000.

c. The total money is the amount of deposits multiplied by the money multiplier.

Money Multiplier = 1/required reserve

= 1/0.2

= 5

Supply = 1,000 * 5

= $5,000

d. With equal amounts held as currency and demand deposits, the money multiplier will be;

= [tex]\frac{1 + Currency deposit ratio}{ Reserve requirement + Currency deposit ratio}[/tex]

Currency deposit ratio is 1 as the ratio to demand deposits is equal which = 1.

= [tex]\frac{1 + 1}{1 + 0.2}[/tex]

= 1.67

Money supply = 1,000 * 1.67

= $1,670

e. If the Central bank increases the money supply by 10% then the monetary base would increase by;

= 10% * 1,000

= $100
