URGENT: ECON about QTM

a) 即係explain mv= pq, 咁v 同q 都係constant唔變既, 當m增加既時候, 呢條theory 就話q係不變的, 會上升的只有p. 咁樣你都差唔多答到一版紙架la.

bi) m1 = money on hand + current account, mr x draw 20000 from saving, 自己手上多左20000蚊, 所以m1 =+20000

bii) 你將withdraw左既20000*0.8先再 * 1/required reserve rate. 你諗下, 當bank a唔keep reserve, 當佢有100000蚊deposit, 佢keep 20000蚊做reserve. 當mr x withdraw 20000蚊, 銀行個20000蚊reserve就無晒, 而佢既deposit = 80000蚊. 佢既新minimun required reserve就係80000*0.2=16000, 即係話bank a要recall番16000loan做reserve. 如此類推...
所以就係20000*0.8*1/required rate of reserve

我呢度比左idea佢點樣將一條問題答得有足夠既資料, 通常alevel 問 explain what is qtm 應該都係8分無走雞. 下面唔silly既人兄唔通以為解釋下p=price level, v=velocity of money就可以拿晒8分??

我以前miss又好, 出面補習又好, 不嬲都係話8分要一板紙. marking scheme d ans最短, 你試下寫咁少野睇下有咩成績ar. 如果解呢條問題唔出到mv=pq, 你點樣可以有足夠內容去拿呢8分. 人地問你what is utility, 唔通整係叫你寫utility is nothing more than an arbitrary assignment for ranking option 咩. 而家唔係f.5.

我以為係money supply tim. 如果係deposit就係20000*1/rr, 因為mr x draw左20000蚊, 所以唔駛*0.8

a.)Explain what is Quantity Theory of Money (QTM)

QTM is a theory used in explaining the relation between nominal money and its flow with the nominal national income. It comes with the equation of MV=PQ under different assumptions. (namely where M=nominal money stock, V= velocity of average money circulation, P is the general price level and Q is the real output produced by an economy within a period.)

Addidtionally, QTM =/= the equation of MV=PQ. This is totally a silly and stupid way to explain QTM in how the factor(s) in equation changes under difference variable(s) being constant.

不是寫得多就叫好，經濟學中沒有這樣的道理。
