CARDINAL: A measurement based on a scale or quantitative numbers, such as 1, 5, or 357.2, that enables a comparison in magnitude. Comparability means, for example, that the difference between 5 and 2 is the same as the difference between 12 and 9. Measures such as height and weight use cardinal numbers. Most economic measures are based on cardinal numbers, including gross domestic product, unemployment rate, the price of chocolate, and the quantity of wheat produced. The benefit of cardinal measurement is the ability to directly compare one measure with another. If, for example, the price of chocolate is $1 a pound and the price of wheat is $4 a pound, then wheat is four times more expensive than chocolate. Ordinal measures, which involve relative ranking, is an alternative type of measure.

KINKED-DEMAND CURVE A demand curve with two distinct segments which have different elasticities that join to form a corner or kink. The primary use of the kinked-demand curve is to explain price rigidity in oligopoly. The two segments are: (1) a relatively more elastic segment for price increases and (2) a relatively less elastic segment for price decreases. The relative elasticities of these two segments is based on the interdependent decision-making of oligopolistic firms.
