呢度真係好,一上來就有d挑戰性題目,等我試下簡單地答啦

1a 使用紅隧的機會成本包括alternative use of 費用和時間,當西隧加價,紅隧多左車,塞車更嚴重令使用者的時間增加了,機會成本也上升
b 個個人的時間成本都唔同,因為有d人無所事事,有d人急住有野做,所以機會成本因人而異

2a 抄書
b 可以不一樣,因為大家choices未必一樣的,所以做老師而放棄另一工作也不同
c 假如做阿sir已經係大家最好的選擇,那麼兩人quit左份工的機會成本也一樣,當然假設佢地係maximize自己利益啦

3 銀行keep excess reserves係放棄左借畀其他人所得的回報,如果現在無乜人借銀,咁keep excess reserves 的機會成本會下降

請指正~

Although the opportunity cost is in the syllabus of CE, I think this kind of questions is too difficult for F4 or F5 student.

我都好同意上面那一位，我差唔多到現在都是唔是好明何謂機會成本，唔知道機會成本的範圍實在太大或者可能老師教師唔好啦！！！不過都是嘗試下志得既！！

Econ的"機會成本"就如
英文的"abc"和中文的"我你他"
是最根的基礎
如未能掌握就必須多複習
不要以為容易便鬆懈
