Superior good

Superior goods make up a larger proportion of consumption as income rises, and therefore are a type of normal goods in consumer theory. Such a good must possess two economic characteristics: it must be scarce, and, along with that, it must have a high price. The scarcity of the good can be natural or artificial; however, the general population (i.e., consumers) must recognize the good as distinguishably better. Possession of such a good usually signifies "superiority" in resources, and usually is accompanied by prestige.
