點解我可以咁撚廢課money creation卡左我成日 :^(
未學你地講果啲QTM 乜乜柒柒
GDP GNP仲記得少少 但fiscal policy 果啲全部唔記得晒未開始溫
得番13日 而家先溫到依度 是咪攞3無望? :^(
對住money creation做到想喊又時不時唔明搞乜 :^(
13日可以做到好多嘢 你而家放棄就注定失敗 點解唔搏埋佢

有題問acc to classical QTM
when money supply is growing at a constant % each per.
Which diagram is correct
點解not PL increase constantly(horizontally
而係inflation rate increase constantly
money supply is growing at a constant %
PL同inflation rate :^(
MV = PY ,
改變率版公式:
△%M +△% V ≈ △%P + △% Y
因為classical( 古典 ) ,即係長期咁,VY不變
條公式就會係
△%M ≈ △%P
另外, △%P亦為通脹率(inflation rate)
有錯請指教。。小弟都想學野 :^(
睇清楚題目先
題目話m is growing at a constant percentage
呢個percentage唔係%△M
佢嘅意思係,M in this year=Initial M * (1+r)^t
t is no. of years passed
r 就係佢所講嘅percentage
咁%△M係咩?
畫一幅graph,y axis 係M,x axis係t,呢幅graph嘅slope就係%△M。
比幅graph你睇
:^(
見唔見到幅graph係越嚟越斜,即係slope一直上升,即係%△M一直上升,根據mv=py,%△P上升,即係inflation rate 上升
至於要解釋點解%△p係上升 constantly, 就牽涉到難少少嘅數學(微積分),呢條題目其實對數底差嘅同學唔着數。

How about Q5a
More people buy electric cars-> competitive demand-> d of diesel cars decreases-> q and p both decrease
substiute既解釋係一邊P跌demand for substiute跌
electric cars P升係因為demand升左
所以要係supply個邊諗 :^(

可唔可以話電動車需求升左價格升左, 所以導致替代品柴油車需求都升左?

其實呢條2015都有啦 :^(
點解你會將所有野都諗到極複雜
我都想問下 :^(
我現實識個人每次都搬到extreme case出黎講,cls

巴打先要明白 price level同inflation rate ge關係。。。。 inflation rate係price level ge改變率。。。。Mv=py只係計緊實數,唔係計緊改變率, 如果題目指ge係m ge改變率呢,你應該用返price level ge改變率去做,即係通脹率
