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.

INFORMATION SEARCH The decision to seek out or produce information based on a comparison of the cost of acquiring the information and the benefit obtained from the information. Efficient information search is achieved with a equality between the marginal cost of search and the marginal benefit of search. Because the marginal cost of search is invariably greater than zero, search effort stops short of acquiring complete information.
