2016年DSE吹「淺風」，ECON亦唔算難，但係有D題目絕對有得爭議，甚至可以廢除。Paper1已經無再出現新題型，反觀Paper2就出手低，畀好少分答好多野。而我相信2016年之後，ECON個範圍已經大定，要出現嘅題型都已經出現過，呢五年嘅PASTPAPER可以成為日後楷模。
先講下今年Paper 1...
1. Which of the following statemetns about economic goods is correct?A. Economic goods may not be scarce.B. People compete for economic good.C. People perfer economic goods to free goods.D. People compete for both economic goods and free goods.
考Economic Goods已經考到悶，但考生嘅創新思維，往往成為考評局嘅出題靈感。上年鬧完你地班契弟亂寫解釋，今年就用multiple choice考返你地。
答案係B。
根據定義，Economic Good is the good where more of it is prefereed to less of it./ The quantity demanded of it is greater than the quantity supplied at zero price. 貴為經濟物品，一定係稀少性，所以must be scarce。A錯。
D之所以錯，係因為Free Good不會帶來競爭(Competition)。因為The quantity demanded of free good is smaller than the quantity supplied at zero price. The amont available is sufficient to statisfy all human wants. 經典例子「空氣」，正常情況下人類唔需要為左呼吸而競爭，或者付出代價而獲得「空氣」。
B同C呢?呢2個答案可以話叮噹馬頭嘅。但係B係定義，C有地方值得商榷。C話People perfer economic goods to free goods.事實上，Economic Good同Free Good我地都prefer，我愛Economic Good，也愛Free Good，不過Free Good泛濫，完成無稀少性，所以我地唔需要付出代價去獲得佢。但係Economic Good就唔同，正因為稀少性嘅存在，所以人類先要透過競爭去爭奪資源，亦即係B的陳述。
