好似concept 掉轉左wor,
應該係import 跌，而令到Y升。

Y升唔係export跌咩

:^(

Y↑, income ↑(tax revenue ↑), import ↑
given the same amount of export
(X - M↑ ) net export ↓

Y好左，GDP升左，Currency應該強左，咁樣export應該會跌左

Assume export不變唔洗咁煩

唔assume,到時仲要寫埋decreases in export is smaller/larger/equal to the increase in import
答案由net export decreases 變到去 uncertain

:^(

唔會呀，一跌一升都會係跌嫁

Dse係咁簡單當一跌一升都係跌就好

:^(

Cliff yeung講到明y升/跌，之後related to change in tax revenue and import
完

X - M
X跌，M升，數學上咁一定跌嫁喎

:^(

同咩簡唔簡單冇關
不過我都覺得Y升之後唔洗考慮export

:^(

之後去tax/import就得，呢個好簡單分析

咁認真做乜啫 2017-4-13 15:14:37 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

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

一開頭都係MC 跌 SUPPLY 升 OUTPUT 升啦 但係後面個度要點樣諗?
因為有時個OUTPUT LEVEL 個FIXED COST 大過 DECREASE 左既MARGINAL COST? 所以PROFIT 跌 有時DECREASE 左既MC 大過FC 所以PROFIT 升?

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)
