Answer:
As a result of the withdrawal, excess reserves decrease by $1,600
The answer is option E). Decrease; $1,600
Explanation:
The following formula can be used to calculate the excess requirement;
C=(1/R)×E
where;
C=total change in M1 money supply
R=reserve requirement
E=excess requirement
In our case;
C=$8,000
R=20%=20/100=0.2
E=unknown
replacing;
8,000=(1/0.2)×E
E=0.2×8,000=1,600
The excess requirement=$1,600
Since the excess reserves require $1,600 after withdrawal of $8,000, then it means that the excess reserves decrease by $1,600 due to the withdrawal
