有時咪OC of X < TOT 咁咪export X , 但係PPF上面有好多點 點解一定要揀x-axis 果點..

上年最後del左邊兩條mc?

我有d期待你地點答E2

條題目我上lecture個陣見到既，改左d用字，我考dse個陣都只係見過一次出面mock咁出。

今晚有英文題目？

姐係佢無講就當係果點？

直線ppf=complete specialisation
assume country A specialises in producing good X and engages in complete specialisations
pre-trade production point就會係ppf上x-axis個點

直線ppf=complete specialisation
assume country A specialises in producing good X and engages in complete specialisations
pre-trade production point就會係ppf上x-axis個點

因為係x-axis個點代表country A produce緊(x,0)
只整good x 唔整good y

Btw你地寫彈性條式出黎睇下

(%change in Qd)/(%change in price)
唔啱？

姐係
((Q'-Q)/Q)/(P'-P)/P)？

有幾多巴絲係咁學？

想問BALANCED BUDGET SURPLUS BUDGET 背後個個EFFECT 係EXPANSIONARY NEUTRAL CONTRACTIONARY 個啲野 係咪要溫?

要明架，不過唔好唔記得睇翻上年Q38

Btw你地寫彈性條式出黎睇下

(%change in Qd)/(%change in price)
唔啱？

姐係
((Q'-Q)/Q)/(P'-P)/P)？

有幾多巴絲係咁學？

書條式一大舊嘅

100%同埋2可以約走架

約走左之後為何要除(q1+q2)
而唔係除q1 ?

唉 做緊by topic past paper 都係咁錯 講緊係做緊scarcity opportunity cost嘅mc都成日錯

唔係太明點解啲題目話條友用$30000 買左樣野 而放棄買另外一樣野果陣 點解計opportunity cost會計埋30000蚊

又唔係好明點解話條友own a house 問條友bear an opportunity cost living in that house because he has paid a sum of money to buy the house 又會錯

我係上面問過野 水平lv1想拎3 果位

類似有一題印花 CE既
30個印花可以換A
20個印花換B
10個印花換C
咁你換A既成本 就係(B+C)因為你原本個30個印花係可以同時換到B同C 你放棄左既野就係(B+C)

好似去睇戲咁 睇戲既成本都要包埋戲飛錢 同埋睇戲既時間

唔知有無講錯 求指教

依條明呀 岩岩都做錯左 淨係諗highest valued option forgone 然黎以為淨係B 但其他我就真係諗唔通 都似成日般龍門咁

好亂 都唔知佢個definition想點 又話highest valued option forgone但又要計埋俾左嘅錢

1st choice: A
2nd choice: B
3rd choice: C
咁嘅情況 你揀A嘅話 OC就會係B嘅value

但如果題目淨係比左一個choice(A)你
問你揀A嘅OC係乜
咁就會係揀A背後所出嘅錢 時間 同其他non-monetary cost

同樣道理
有個人用$30000買左樣野(當係A)個題
1st choice: A
2nd choice: B
但當B對買野個個人黎講嘅value係細過$30000嘅時候 就會變左：
1st choice: A
2nd choice: $30000 cash
3rd choice: B
咁OC就會係$30000
而當個$30000+value of B=value of A嘅時候
咁你揀A 已經係放棄左both B and $30000 cash
所以 當題目冇講到明value of B係幾多嘅時候 你唔知B定$30000 cash係個個人嘅2nd choice(highest-valued option forgone) 所以OC就會包埋個$30000

有個人own a house個題
paid a sum to buy a house已係sunk cost
唔計入OC
真正嘅OC係rental income forgone(自往緊冇得租比人收租)

有錯請指正

好清晰

其實opportunity cost = explicit cost + implicit cost?
Implicit cost 同 opportunity cost 係有啲混亂
