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.
详解是 正常财之价格变动与需求量的变动关系，其中替代效果为负相关，所得效果亦为负相关。
===================================================
我的疑问：但是正常财若用x-y图来画，替代与所得效果不都是往右跑吗?
那麽这种题目，到底要用哪种解好呢?
