[Econ衝**] 2017 DSE 經濟科試前討論區

問書：

1. Indirect tax（間接稅）係咪一定唔郁AD（總需求） ?

2. Price（價格）有咩functions（功能）？

3. Inelastic Demand（低彈性需求）係咪就係畫直d條demand curve（需求
曲線）？

4. 點先叫positive statement（實證性陳述）？

1) side effect會有機會郁

2)allocated
仲有一個rot字頭英文字母跟住唔記得咗係咩
3）可以咁講 或者一條demand curve mid pt 嘅下面
4）可以用事實或者調查證明係啱

1. Not sure
2. Function of price: allocating (determine what to be produced) and rationing (highest payer get the good)
3. No. for any demand curve, upper region is elastic region, mid-point is Ed=1, lower region is inelastic region
4. Positive statement is a statement that could be proved or disproved by fact

1 should be yes(?) indirect tax on a certain good causes its supply curve shift left, and P increase Q decrease. If demand is elastic, %decrease in Q is greater than % increase in P. Then its expenditure drops. Therefore consumption expenditure drops. Assuming that general price level doesn't change after imposing the indirect tax, AD drops.
Not sure

??????

你可唔可以解釋下點解咁諗？

If demand inelastic total expenditure will increase upon impose of indirect tax -> C increase -> AD increase??

Retake上年lv 3 今年無乜點掂過
掛住温其他科 但數已死 無望了
想問考完m1但有9日有無可能衝到4
呢9日除咗睇dse pp之外有無啲咩建議可以溫得有效率啲

最好係溫paper，你aim幾多？

巴打錯得好嚴重喎
首先應該分番開demand and supply model 同ASAD model先
依家我哋應該係以ASAD model討論，demand呢個term唔會出現。

2. Price（價格）有咩functions（功能）？

3. Inelastic Demand（低彈性需求）係咪就係畫直d條demand curve（需求
曲線）？

4. 點先叫positive statement（實證性陳述）？

我既答案：
1. 唔係，有d間接稅（例如sales tax啦）會令firms既profit減低，減低佢地投資意慾，I 跌，AD跌。


2. (1) Allocative function 分配功能 (2) Rationing function 配給功能，呢兩個可以係syllabus搵到。

我想講既係(3)，呢個係syllabus搵唔到既，叫Signal Function 訊息功能，呢個係2015 pp第一次出現，內容大意係話 Prices help transmit information about consumer demand relative to producer supply 價格傳遞有關消費者需求與生產者供應的資訊。呢個相信唔太難明，如果唔清楚既再問啦。


3. 唔係，一般同學覺得Inelastic Demand（低彈性需求）就係畫直d條demand curve只係錯覺，真正既分法係畫一條掂住x,y axis既demand curve，上半部分係elastic 高彈性，下半係inelastic 低彈性。

咁點解會有呢個錯覺？係因為你畫一條直d既線，你好少會掂哂x,y axis，通常都只係掂住x axis，同y-axis有d距離，你如果extend條線去掂y-axis，你就知你係畫緊線既下半，所以係inelastic 低彈性，反之亦然。


4. (1) Value judgment is NOT involved 不涉及主觀價值判斷 (2) Refutable by facts, disagreement to them can be settled by appealing to facts 可被事實推翻，能以事實證明真偽。

首先應該分番開demand and supply model 同ASAD model先
依家我哋應該係以ASAD model討論，demand呢個term唔會出現。

首先DSE 唔會咁問
第二就係唔應該以direct tax 或者indirect tax 去分會唔會影響AD
因為有啲會影響AD, 有啲影響SRAS 有啲又會無影響
再深入啲已經out 曬syllabus

補充一點，第1條既情況，係般情況下叫你畫都剩係郁AS得，給果好似sample paper 咁講明，先會郁AD，大家留意一下

1 should be yes(?) indirect tax on a certain good causes its supply curve shift left, and P increase Q decrease. If demand is elastic, %decrease in Q is greater than % increase in P. Then its expenditure drops. Therefore consumption expenditure drops. Assuming that general price level doesn't change after imposing the indirect tax, AD drops.

咁燒左佢
一向大家都知香港中學econ 書都是廢的
利申：當年無買過書 5**

Q2呢題點搞?

唔係D?

你doubt係(2)？

因為free goods 係some is preferred to none，即係係會有total WTP，只係我地唔想再willing to pay for an extra unit，free goods 既Total WTP都可以好大。

(3)?

3 係everyone嗰度出事，應該唔係everyone

econ啲mc如果有everyone、must呢啲講到咁盡嘅字眼多數都係錯嘅option，因為凡事冇絕對

巴打 我諗住揀E2做啦
但文字題有乜重點要記
見佢多數出HDI 除此仲有啲咩文字題會出

仲有 我唔知係邊到見到有人話cut左MSB同MSC
係咪真 唔該哂巴打

15年 5*
今年再考 aim 5**
平時有幫人補習 但我唔知依家可以點温
做咗PP 13 15一次
求賜教

Aim lv3 但只有lv1 甚至U 嘅水平
有何建議

[quote]aim4既留名
BTW想問下想拎4的話MC要啱幾多條左右?

其實都想講，好多巴絲用mc黎睇成績，其實影響大局既係LQ

不過你<ins>最少</ins>都要拎到cut off percentage啦（i.e. 45*0.65 = 30)

好
想問下可以點樣做MC做得好D，我依3年黎經濟都係衰MC，未試過拎3字頭

concept要清楚 要睇哂每一個option highlight keywords 知道其他option 點解錯 between 真係唔識嘅話睇下有冇 option 有must 之類嘅term 多數錯

Aim lv3 但只有lv1 甚至U 嘅水平
有何建議

做pp mc
