[ECON] 2017 DSE經濟科討論區(3)

仲有關於economic of scale
係咪有細分唔同type架？例如？

seems out-syl bor

internal and external ?

不，好似見過唔記得ce定dse pp出過
答案大概係Financial economic of scale 唔知係我記錯定點

financial economies of scale
managerial economies of scale
purchasing economies of scale
marketing economies of scale
technical economies of scale
R&D economies of scale

你要知道點樣會令average cost下降

但好似唔洗知個名

lv2同lv3大約幾多成

推

Lv2好易到 溫下就夠 唔知%
Lv3都幾難 因為起碼53%以上先有機會lv3 上年好似56% 唔太記得

我認為難係因為我都係依兩個星期先開始學econ

我F6尾同Firms都唔知佢講咩

睇herman yeung快速學晒佢 我都係依18日學曬3 年嘅野 加油

背書野睇佢d片啦

有d難concept佢唔準架

Paper 1 MCQ
1. 一分鐘一條，唔好停係一條太耐，要留10分鐘check卷。
2. 今日睇翻做過既題目，唔好再做太多新野。
3. 唔識既就試排除法
4. 睇清楚NOT true
5. 留意題目提問用字，MUST(必然)係要向反證既方向諗，諗下們會唔會錯。MAY(可能)你係要指出佢可能不，諗有無一個情況佢會岩。呢d字撈亂就會錯。
6. 題目可能有錯，揀最佳答案。
7. 今年應該會再少d直接問definition既題目。
8. Elasticity 彈性小心睇，係計緊demand 定supply係睇你move along邊條curve，不是你shift 個條。
9. 睇清楚Average(平均)/Marginal(邊際)/Total(總)
10. Classical QTM=LR QTM (上年一班人唔識)
11. Positive statement實證陳述係要refutable by facts(可被事實推翻)，而唔係要正確。錯既statement(e.g. 我放手既枝筆會向上飛)都可以係實證。
12. 唔好複雜化條題目，推理用正常方式做，有時intuition 好重要。
13. GDP睇清楚d components，有時係net(淨)，有時係total(總)，Investment Expenditures 都要睇清楚。

有冇人做左cliff yeung份mc
Q20點做

想問下呢個係咪錯
同埋問到why mb=d or mc=s應該點答？

係咁樣read

咁點解呢題既答案係B？

15題完全唔識
25題點解(2)(3)唔岩?

個表係收稅前/後？

明顯係稅後

稅前Pe Qe係咪11,65 稅後係12,60? 咁既話個價格上限唔係變左無效?

（sample pp）

P=mc 就係profit maximaization output level
Mc有時係平 唔一定升
揀best answer

明顯係稅後

option B :升左10%可以係 gdp deflator 由50 升到50x1.1=55, real GDP > nominal
option C:有d物品價格可能不變/跌

A pianist plays the piano at home and he does not pay or receive payments from his neighbour.下面邊個岩？
A: there must be a divergence between private and social benefit if his neighbour likes the music.
B: there must a divergence between private and social cost if his neighbour doesn't like the music.
C: the above situation must be in efficient whether or not his neighbour likes or dislikes the music
D: the above situation must be efficient whether or not his neighbour likes or dislikes the music

反而option c先得意
given唔同mc curve, 決定唔同產量, 原則上又冇錯
只係呢個關係喺受價同覓價都適用, 所以仍然解釋唔到點解mc curve又係supply curve呢個受價獨有既情況

D: the above situation must be efficient whether or not his neighbour likes or dislikes the music

cliff mock? 我之前問過
B
post(2)有好詳細解答
簡單黎講 個pianist有機會彈至efficient level benefits未必有divergence
但個neighbour唔鍾意嘅話 彈一秒都係dislike cost會有divergence
