AL Econ Question on Banking System

簡拿華路

In an economy, currency currently held by the public amounted $6,500Million
held by authorised institutions amounted $3,500Million

Suppose the public holds $1 currency in hands for every $50 bank deposits
banks keep $3 for every $100 bank deposits as excess reserve

The minimum reserve ratio is 20%

1)Max. possible amount of money supply is $40,800Million
2)Max. possible amount of bank deposits is $60,000Million

3)After the multiple deposit creation/contraction, the amount of reserves held by banks is $9,200Million
4)After the multiple deposit creation/contraction, the amount of cash held by the public is $1,200Million



點解 1,3 係岩的

我想問係咪一開始乜都唔做,就有$6500 mn 既 Cp 同埋 $3500 mn 既reserve in bank sector??

跟住d人就將9/10 既錢存入銀行?

用Monetary Base(MB)
MB = 6500m + 3500m = 10000m
MB = 0.02DD($1/per$50) + 0.23DD(Required reserve + excess reserve ratio)
10000m = 0.25DD
DD = 40000m

Cp = 40000m x 0.02 = 800m
Max. Money supply = 40000m + 800m = 40800m

Amount of reserve held: DD x reserve ratio
40800m x 23% = 9200m

[唔正宗]我自己理解o既係呢堆錢係真係有o既, 係政府印o左o既錢o既數量, 即係話有所有流通緊o既銀紙係呢個數[/唔正宗]

其實monetary base 多數都係 mc 用o者, 唔多駛理佢真正解釋
