GIFFEN GOOD: A rare type of good seldom seen in the real world, in which a change in price causes quantity demanded to change in the same direction (in violation of the law of demand). In other words, an increase in the price of a Giffen good results in an increase in the quantity demanded. The existence of a Giffen good requires the existence of special circumstances. First, the good must be an inferior good. Second, the income effect triggered by a change in price must overwhelm the substitution effect. A Giffen good is most likely to result when the good is a significant share of the consumer's budget.

MARKET STRUCTURE CONTINUUM The four common market structures, perfect competition, monopoly, monopolistic competition, and oligopoly, can be viewed as a continuum based on (1) differences in the number of firms in a market, (2) the relative size of each firm, and thus (3) the market control of each firm. Perfect competition lies at one end and monopoly at the other. Monopolistic competition is close to perfect competition and oligopoly is near monopoly. The essence of the continuum is that monopolistic competition blends into oligopoly, with no clear-cut line of separation.
