來源:97年成大財經所 (例如: XX 年度高考, XX 年度研究所考)
科目:經濟學
問題:
19.You deposit $4000 in currency in your cheeking account. The bank holds
20 percent of all deposit as reserves. As a direct result of your deposit,
your bank will create
(a) $200 of new money.
(b) $800
(c) $1600
(d) $3200
我的想法:(d) 4000*0.8 = 3200
抱歉...沒打清楚!
因為高點的解答是
4000*0.8+4000*0.8^2+4000*0.8^3+...........= 4000*0.8/(1-0.8) = 16000
所以我認為高點明顯錯了,題目應該只是問你存的那間銀行,所以只取第一項
4000*0.8 = 3200 ,但對自己又沒信心!
先謝謝各位囉!
