Necessity good 必需品

(重定向自Necessity Goods)

In economics a necessity good is a type of normal good. Like any other normal good, when income rises, demand rises. But the increase for a necessity good is less than proportional to the rise in income, so the proportion of expenditure on these goods falls as income rises. This observation for food is known as Engel's law. The income elasticity of a necessity good is thus between zero and one.
