Gillry 問: Suppose a HK resident camcelled a flight provided by a Japapese airline and got a refund. He than bought a ticket from Cathay Pacific at the same price. This wouldA. increase HK's private consumption expenditure and GDP.B. increase HK's private consumption expenditure and GDP remaind unchanged.C. decrease HK's value of imports and increase its GDP.D. decrease HK's value of imports and its GDP remaind unchanged.answer係A* 但係import吾係應該計入private consumption..之後再o係import度減返架咩!? 甘private consumption吾係應該係remain unchanged咩!?甘個answer點解吾係C既!?
Gillry,
題目入面講咗兩件事:1. cancel Japanese Airlines機票,然後refund, 即係冇買過機票 (セ事都冇發生過), 所以GDP冇變。
2. 買Cathay Pacific Airlines 機票, 由於Cathay (國泰)屬於香港嘅resident producing unit (常住生產單位), 佢提供咗services(服務), 當然計落香港嘅private consumption expenditure(私人消費開支), 用番GDP=C+I+G+(X-M)條式, C升咗, total demand會升, GDP就會升喇, 答案係A
明白嗎, Gillry?

仲有，我想問究竟decrease in import係會令GDP上升定係remain unchanged!? 同埋如果o係elastic demand既goods加tax(本身已經有，而家加多D),甘個tax revenue係升係跌定係uncertain? thank you =)
