係呀 tariff/quota個2幅
正常嘅話我識
但demand/supply shift我就唔get

冇上到cliff堂 而家好後悔

不如討論下大家最怕咩topic同最中意咩topic 啊

我先 : 最憎
externality (paper 2唔知點答) efficiency ( 好驚佢溝埋d market structure問我d咩mc點解等於 s )

最中意, 成個macro我都中意 係唔中意e2 d咩全球化/ 經濟增長 個d吹水野 ( 成日答錯 )

數據題
雖然得個1-2分,但係寫左唔知自己寫乜鳩

Small economy個2幅圖
有時demand/supply shift就唔識
有冇巴打講下

一幅講importing countries, 一幅講exporting countries 嗰part?

係呀
一幅包哂domestic同import

哦,我明啦,係幾惡哽(抛下磚)

我當年未上手個陣,做過題,大概記得好似係話: country A is a small opened economy, country A imposed tariff on all its imported goods. Meanwhile, demand of its imported goods increase. 之後要你畫張圖咁,解釋對imported price同 q點玩法

dse ge巴打們試下畫下

[ 中文版 : 甲國係小型經濟體,它對所有進口貨物微收關税。設甲國對其進口貨物需求上升,以一圖輔助,解釋對甲國進口價格及數量的影響。]


大學or above勁抽ge巴打試下唔好答住
得dse ge同學仔做下先

( 原諒我英文差)

做完試下貼上黎咁
domt be shy,


同人討論學術野真係好有趣

btw其實呢part你攪得清d pw啊,quality of goods啊 已經夠玩

上面講interest rate睇到我好亂

tariff+demand increases
then P remains unchanged and Qi rises
依個好似係最typical嘅問法 有啲題目會問埋domestic production/consumption個啲 有時都要load好耐先get

上面講interest rate睇到我好亂

唔好理咁多
總之
nominal interest rate=expected real interest rate+expected inflation rate

actual real interest rate=nominal interest rate - actual inflation rate

nominal interest rate 只有一個,冇分actual /expected , dse嚟講

Thx 總之nominal不變呀嘛

上面講interest rate睇到我好亂



總之就當費沙 有兩條式( 答long q答 1 式好啦)
i仔係兩條式通用
預期版
(expexted version) : i = r (e) + △%p (e)
真實版(已知版)
(actual version) : i = r (a) + △%p(a)

(△%p即通脹率, a for actual ,e for expexted, r for " real interest rate
,i for nominal interest rate)

另外,要計什麼鬼屁 cost of holding $(持有現金成本)

睇返上面我post火柴人張圖,幾有用

高手們係拗緊,究竟 i仔有無得expected (dse唔洗理)
2017-04-21 01:01:05
DSE Econ 2014 Paper 2 Q5cii的expected nominal rate of return同actual nominal rate of return咪唔同囉

巴打 呢隻題都幾撚狗,你唔知 import price係 = pw, 而small opened economy係price taker, 唔可以改變price ge話,你走去郁p已經gg

回ir3555巴打
因為冇人借錢簽約嘅時候會用real interest rate嚟做合約條文
例如我借一百蚊比你,規定你一星期後還100蚊+1本經濟書比我
冇人會咁,只會叫你一星期後還100蚊加10蚊比我, nominal interest rate = 10%
dse syllabus 就係冇人會set死個real interest 嚟借錢,at least 銀行/邦民借錢比你唔會
以下內容dse考生睇完就算
當然,for non-dse purpose, 其實現實世界可能真係會set 死real interest rate, 例如上面個例子,real interest set 死左係一本經濟書,咁借錢嗰陣 嗰本經濟書嘅價錢咪就係你嘅 expected nominal interest
而還錢嗰時本經濟書嘅價錢就係你既actual nominal interest

不過!冇錯nominal interet 係可以分expected同real,不過我地無興趣知!因為錢(nominal)係無意思嘅~錢只係用嚟換real嘅嘢( 物質)~~所以我地只係有興趣知expected real and actual real~~

還一本書係補償你購買力改變, 但係呢本書本身有相對價格對應住既金錢價格, 如果一星期後呢一本書價錢有改變, 你就可能有賺或者有蝕
呢一本書係expected nominal interest, 因為可以拆返開做一本書(預期購買力補償)同呢本書價錢(預期物價補償)
反而係物品個數量正路一般都唔會變(一本書), 而物品個價錢就會有機會變(書既價錢), 咁點解唔值得睇actual cost即係最終書本書數同埋書本價錢最終改變?

除非你當左本書個價錢係不變
書本數量係合約條文set死左,書本價錢先會變~借錢時的書本價錢係expected nominal interet , 還錢時的書本的價錢係actual nominal interest, 但係nominal interest 嘅actual 同 expected , 只係錢~ 經濟學其中一個好重要既野,就係人類make choice 唔係base on 錢(nominal),而係base on 物質(real)~~~~~你同我講expected nominal interest 係50蚊,而家actual係70蚊,即係本書貴左,但人類冇興趣知,人類只關心呢70蚊可以食到幾多餐飯~可以搭到幾多次巴士~nominal ignores price level, which fails to tell us that~~so we do not want to know nominal interest rate

你所指既合約set死書本數量係因為本金係100..........唔係合唔合約既問題...
你借100蚊出去, 一段時間後拎返, 自然要計呢100蚊當下呢一刻既購買力, 再加未來物價改變...
本金講好左, 所以一般黎講物品數量先lock死...


我上面打錯左, 應該係"除非你設定個expected inflation rate係估中左將來actual inflation rate, 咁就冇賺冇蝕, 即係好似"唔洗"考慮個物價變動因為你預知左
名義利率今日決定, 將來物價水平係唔知, 今日就要估埋將來物價...
所以1+R先=(1+r)(1+物價預期改變)

你上面例子咪就係只係考慮左個物品購買力改變....
現實世界借錢還息確係指還錢, 但呢個本金以外既利息唔單係預期通漲通縮..仲可以包埋預期投資賺蝕............

所以我先用蘋果做例子, 因為錢本身自己唔識變多變少...實物應該易睇清楚d成件事...

你上面提到「還一本書係補償你購買力改變, 但係呢本書本身有相對價格對應住既金錢價格, 如果一星期後呢一本書價錢有改變, 你就可能有賺或者有蝕」咁請問如果我年頭唔expect有inflation 本書只係係年尾出現 咁我又點會預左依本書年頭嘅價錢就係我嘅"expected nominal interest rate" 而年尾就係"actual nominal interest rate"?

你expect冇inflation, 即係你設定你個物價補償係0咁解..
問題係你延遲消費/投資, 你要補償/拎返兩樣野, 一係購買力/物品數量, 二係個物價...所以費沙公式先有呢兩部份
你年頭估冇, 如果年尾真係冇, 咪即係估中左, 所以睇落咪似冇物價變動既問題...即係上而書個例子, 還一本書..
除非用埋書既數目去計埋個物價改變, 即係一本書其實包埋物價改變, 咁冇話唔得, 只係簡單轉換...
但你拆開成件事, 如果分唔返開呢兩樣野, 咪出事...

事前係expect, 事後係acutal/realised, 我冇話兩樣野一定唔相等

如果講事前set死real,其實咪即係floating interest rate

DSE Econ 2013 Paper 1 Q24 option A, DSE Econ 2015 Paper 1 Q36 Option C, DSE Econ 2016 Paper 1 Q37 Option (2)都出現過

明白,即係dse黎講都係睇佢prerequisite
佢話r係 fixed ge咁就變 r = ie - △%pe

outliers巴打份2017 mock搞成點

出咗一堆新題目
而家好無恥咁在2012-2016的mock搵緊題目放入去
2017-04-21 01:27:27
仲有 8 日考,為增加討論氣氛同想同大家一齊提升實力入u, 大家互相抛磚,抛下d你認為好難or 有趣又學過ge concept出黎考下大家


我抛先

eng ver:
refer ro the following balance sheet. suppose there is no Er initially. If there is not enough demand of loan for bank now such that the maximum demand for loan has reduced to $500. what is the new reserve and deposit ?

中ver : 跟據以下資產負債表。若銀行沒有足夠的貨款需求使得貨款的最大值下降至$500.
求新的儲備及存款值。

表:
rrr=10%
R100 D 1000
L900

條野原本係英文題目,中文ve r可能譯得衰
