曾經有以下問題:
A large number of departing tourists were delayed at the airport in Hong Kongduring a typhoon. Suppose they were delayed 24 hours on average. Explain whether their opportunity cost of that visit to Hong Kong would have changed as a result of the delay.
假設有一個遊客是自僱人仕,他到香港的機會成本是這幾天的收入加上旅費。如果因打風被逼滯留香港多一天,他損失了一天的收入,他到香港的機會成本因打風而增加了。但機會成本是本於選擇,因打風而要留港多一天是無其他選擇可以代替,可以說該旅客訪港的機會成本沒有因打風改變嗎﹖如果冇變應如何看待那一天損失的收入﹖
請只考慮損失收入方面有冇機會成本,不要扯上其他開支或打風冇野好做等。
