[考試] 問一題個經的題目了~感謝各位板大
although some of the statements below are true of both normal goods
and inferior goods, only one of the statement defines a normal good. which one?
===================================================
答案是:normal goods are those for which the income effect is negative.
詳解是 正常財之價格變動與需求量的變動關係,其中替代效果為負相關,所得效果亦為負相關。
===================================================
我的疑問:但是正常財若用x-y圖來畫,替代與所得效果不都是往右跑嗎?
那麼這種題目,到底要用哪種解好呢?
