唔使

想問下點解quantity increase, mc 會increases?

你畫個圖出黎
又有咩可能隨住q升,mc會升

我知阿 但係點解

大過profit maximising output level,q升mc升

唔明你講乜 我意思即係好似mb curve 係downwards sloping咁,果原因係 consumption increase -> benefit decrease,咁mc 有冇依啲原因嫁

因為Law of diminishing marginal returns
當labour的數量增加,labour的marginal product會下跌,代表生產多一件output所需要的labour愈來愈多
假設wages rate不變,生產每件output所需要的成本就會增加
因此當output的數量不斷增加,MC亦會不斷上升,MC curve所以係upward sloping

想問點解會係recession?

想問點解會係recession?


呢一part其實考評局自己都亂晒大龍

正常黎講,real gdp 跌,就係recession
呢條題目,%△real gdp係負數,即係real gdp 跌, 所以recession


咁點解條curve向上行

但係正常dse 拎分都係答返recovery?

business cycle個到我都覺得亂亂地,其實係咪即係話 除左curve ge vertex( peak同trough). 其他>0 ge位置不論上升位定下降位,都係recovry, <0 ge位都係recession?

屌,睇hkeaa marking同出面d mock d marking人人唔同解法

同埋又想問下,係卷2,要解釋 transportation cost導致兩國唔會有mutually beneficial trade, 係咪一定要話 transportation cost > potential cost?
唔可以 將是但一邊個國家計埋個transportation cost再減 Tot之後話 gain from trade < 0 所以唔會有mutually beneficial trade?

if transportation cost > total gain from trade = no mutually beneficial trade?
唔知係咪咁 求指教

再加多條。。。究竟 Y ⇧ 失業率是否必然下降?
我聽過有人講話 唔係,應該答不能確定
但係返dse角度, 係咪應該咁理解?
呢到我比hkeaa玩到好kick, Y ↑ 同 recovery係咪又係同一樣呢? 因為hkeaa個business cycle又話,recovery唔一定係代表y↑, 只係△% y ↑ 係個陣y有機會↓, 救命,有無巴打幫幫拖

中文版本題目10(a): 通_率,打漏左個字

11(d) - XX供應更多的土地 應該係想講 供應更多的 XX 土地?
14題同時出現 DVD播放"機" 及 DVD 播放"器",另外14題總分只有14分非16分。

我中學係中文讀Econ,大學有用英文讀過;睇過中文卷同英文卷估計你係先出左英文卷後翻譯做中文卷。少少意見,如果想中文卷字眼似考評局既話,以下題目可以參考:
Q8(b) - 字眼參考:DSE2012Q9(c)
Q9 Balance sheet - DSE2016Q8
Q10(e):字眼參考 - DSE2013Q12(c)

又想問 係perfectly competitive market
supply curve/demand係咪無可能 垂直?

事關,我想知道 supply curve垂直,如果有surplus/shortage, 個dwl會係邊?
係咪唔會考?
