Facebook講話出左Final Practice Paper
想問下邊個有Final Practice Paper

我有2012-2017佢既全部mock
即係今年今展果份都有 想搵人交換
有興趣係度覆一覆 thanks

推

有andrew lo 換唔換

巴打你真係風趣幽默

Fd send過黎 想問下點解a 個option係錯？

可能佢諗緊hk ge税掛
咁事實hk ge累進税progressive tax又真係all直接税direct tax黎ge
不過我覺得條q有d kind囉

因為個個唔係累進稅既definitin

係wo 佢加個" 指 " 字唔會好d咩

唔需要加，已經好清晰

我完全唔明點解佢做到首席

想問呢幅圖
我點樣可以知country A做good X定good Y 有CA?
Country A Production point係F
另外如果world price 1變左world price 2
咁個ca會唔會變？

應該要多d info? e.g slope of the production point?

條題目得咁多info

不如成條貼啦

btw " 鳩up ""
佢pw 1, 如果平衡地後移，移至與ppf相切(tangent to ppf)
咁你應該會發現佢 相切點個slope < production point's slope
咁即係country A生產goods x個oc > tot
咁暗示佢會import goods x
咁 goods Y有c. a ?

你指咁樣？

係

應該無死啦，DSE d cpc都係玩開平移 , 加上 curve平衡移動，slope不變


btw小弟e2 廢物，睇下會唔會有更好解答吧

燈塔marketing嘅野我地真係識條毛

E2個條

(b)個度無啦啦講slope，想你compare slope啦應該

即係production point斜過world price條slope就good Y有CA
平過WP條slope就good X有CA?

屌我都係e2廢物, 個學生問我呢題我唔撚識
果陣我考e1

想問當inflation is fully anticipated嘅時候，咩情況下會有redistributive effect of wealth?

想問當inflation is fully anticipated嘅時候，咩情況下會有redistributive effect of wealth?

應該冇

E2個條

(b)個度無啦啦講slope，想你compare slope啦應該

即係production point斜過world price條slope就good Y有CA
平過WP條slope就good X有CA?

呢個都算必需識

某ppf point slope > tot = import goods X
某ppf point slope < tot = export goods Y

因為佢貿易ge假設係 2 國 2物品
一邊有cd, 時另一邊有ca

想問當inflation is fully anticipated嘅時候，咩情況下會有redistributive effect of wealth?

無

但仍然會有收入再分配呢個動作
e. g員工見到price level↑, 佢會屌柒個老闆叫佢加薪。。。

再分配" 效應 " 係要有損失/得益 先叫效應

就咁再分配係一個動作

When inflation is fully anticipated, contracts will be adjusted in order to avoid gain or loss
But in reality, contracts cannot fully adjust
我覺得係咁

我覺得係咁

Theoretically, incomr redistribution occurs when there is unanticipated inflation. However, in reality, there is still income redistributive effect when inflation is fully anticipated because:

1. suppose adjusment cost is negligible, income will be redistributed from those social groups with less bargaining power to those with more bargaining power even if inflation is fully anticipated.
2. Besides, no matter inflation is anticipated or not, the public who hold cash for transactions will lose becaus3 the purchasing power of money falls with inflation




btw dse問，由其mc答無 is ok

咩係inflation tax

咩係inflation tax

inflation tax :
inflation can be viewed as a taxation that redistributes income from the public to the government.

咩係inflation tax

inflation tax :
inflation can be viewed as a taxation that redistributes income from the public to the government.

其實即係講緊 price level ↑ --> nominal income ↑ >> tax revenue of gov ↑
呢一個效果

cliff mock有題mc話會有，我諗係指緊你講嘅case

咩係inflation tax

inflation tax :
inflation can be viewed as a taxation that redistributes income from the public to the government.

其實即係講緊 price level ↑ --> nominal income ↑ >> tax revenue of gov ↑
呢一個效果

Price level increase
Nominal income 唔一定increase
Cuz Y will decrease
So tax revenue of gov may not increase

我覺得係講緊hold cash既話就好似比緊tax
類似return of holding cash 咁

其實仲有好多 out又唔out得晒syl ge concept

咩 stagflation滯脹啊
market force市場力量啊
seasonal unemployment季節性失業
spillover effect溢出效應
demand-pull inflation需求拉動形通脹
cost push inflation成本推動形通脹
from increase in G to increase in ad( 點解平衡預算係輕微擴張性條proof)
unanticipated monetary policy vs anticipated monetary policy
非預期的貨幣政策同被預期的貨幣政策

巴打我知，呢樣其實用 QTM ge short run可以解釋到 不過普遍會咁諗姐
