In the economy, the following statistics describe the money supply:
CU=$1000 billion
RES=$75 billion
DEP=$1,500 billion
Given these data, calculate the amount of the monetary base:
BASE =9, billion
Calculate the quantity of the money supply:
M=, billion
Calculate the ratio of reserves to deposits:
res = (carry out to four decimals)
Calculate the ratio of currency to deposits:
cu=, (carry out to four decimals)
Calculate the money multiplier:
mm=
(carry out to four decimals) Now, suppose a shock causes banks to change the amount of reserves they hold relative to deposits, so that res changes from 0.0500 to 0.0417 . Suppose that when this happens, both cu and BASE do not change. However, the change in res will affect
mm,M,CU,RES
, and
DEP
. Calculate the new value of the money multiplier:
mm=, (carry out to four decimals)
