ORDINAL: A measurement based on a ranking, such as first, second, and third, that enables a relative comparison of more or less. Relative comparability means, for example, that first is more than second and second is more than third, but how much more is not known. Cardinal measures, which use a quantitative measurement scale, is an alternative type of measure. An ordinal measure can be thought of as a list for high to low, good to bad, top to bottom, and are often based on subjective evaluations of items. The notion of ordinal measurement is most often seen in the economic analysis of indifference curves and utility.

- Marginal product measures the physical productivity of a given unit of input.
- Marginal revenue is the change in the total revenue resulting from a change in the quantity of the output produced.
- The combination of marginal (physical) product and marginal revenue leads to the fourth marginal concept:

- Marginal revenue product indicates the value of the output produced by an input.

INTEREST RATES, AGGREGATE DEMAND DETERMINANT One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in interest rates cause a decrease (leftward shift) of the aggregate curve. A decrease in interest rates an increase (rightward shift) of the aggregate curve. Other notable aggregate demand determinants include the federal deficit, inflationary expectations, and the money supply.
