ｍｏｎｅｙ ｃｒｅａｔｉｏｎ既問題～
假設有間銀行佢既liabilities有＄４０００ deposit
assets有＄１２００ reserve 同 ＄２８００ loan
咁required ratio ratio係30% ,,所以而家就冇excess reserve啦~
然後,,$300既 currency is put into the bankingsystem..
咁deposit 變左$4300,,reserve變$1500,,loan無變
what is the maximum amount of deposit and loan this $300 created?
deposit=$300x1/0.3 = $1000 呢度我明~
但係點解loan係=$300x(1-0.3)x1/0.3 = $700 既!?
條式唔係300x1/0.3 = $1000 架咩!?
點解要x多舊(1-0.3) 既!?
之前做exercise都只係x1/r ..
幾時要x埋呢舊野!? 唔係好明 -) thx~ 不如完整咁打晒成條題目出來，我想幫你都好難，因冇題目我好難做，如果係pp最好post埋年份題數 Assets
1200 reserve + 2800 loan
Liabilities
4000 deposit
Assets
1500 reserve + 3500 loan
Liabilities
5000 deposit
300/x = 0.3 (1200/4000 = 0.3)
x = 1000
1500/0.3 = 5000
5000 - 1500 = 3500 (max loan)
3500 - 2800 = 700 (increase effect)
i.e. 300/0.3 = (1000) increase in max deposit, but need to (-300) for the increase in reserve
300/0.3 - 300 = 300(1-0.3)/0.3
