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.

                           SHORT-RUN AGGREGATE SUPPLY AND MARKET SUPPLY: The short-run aggregate supply curve, or SRAS curve, has similarities to, but differences from, the standard market supply curve. Both are positively sloped. Both relate price and quantity. However, the market supply curve is positively sloped due to the law of diminishing marginal returns and the short-run aggregate supply curve is positively-sloped due to inflexible prices, the pool of natural unemployment, and imbalances in real resource prices. | Two Similar Curves |  |
To illustrate the specific short-run aggregate supply and market supply curve similarities and differences consider the graph of a positively sloped curve displayed here. Is this a market supply curve or an short-run aggregate supply curve? A cursory analysis suggests that it could be either.To reveal the similarities between the both curves, click the [Market Supply] and [Aggregate Supply] buttons. Doing so illustrates that both curves are positively sloped, with each virtually overlaying the other. Consider the differences between these two curves. - First, note that for the market supply curve, the vertical axis measures supply price and the horizontal axis measures quantity supplied. For the short-run aggregate supply curve, however, the vertical axis measures the price level (GDP price deflator) and the horizontal axis measures real production (real GDP).
- Second, the positive slope of the market curve reflects the law of supply and is attributable to the law of diminishing marginal returns. In contrast, the positive slope of the short-run aggregate supply curve is attributable to: (1) inflexible resource prices that often makes it easier to reduce aggregate real production and resource employment when the price level falls, (2) the pool of natural unemployment, consisting of frictional and structural unemployment, that can be used temporarily to increase aggregate real production when the price level rises, and (3) imbalances in the purchasing power of resource prices that can temporarily entice resource owners to produce more or less aggregate real production than they would at full employment. Similar, but different.
Most notable, the differences between market supply and short-run aggregate supply means that it is not possible to merely add up, or aggregate, the market supply curves for the thousands of goods produced in the economy to derive the short-run aggregate supply curve. The short-run aggregate supply curve dances to its own music and plays be its own set of rules.

Today, you are likely to spend a great deal of time touring the new suburban shopping complex looking to buy either 500 feet of telephone cable or a package of 4 by 6 index cards, the ones with lines. Be on the lookout for slow moving vehicles with darkened windows.
