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.

Substitution Effect
|
|
|
The second reason for the law of demand is the substitution effect.- The substitution effect exists because a change in the price of a good makes this price relatively higher or lower than the prices of other goods.
- The higher the price of a good, then the more expensive it is relative to other goods. The lower the price of a good, then the less expensive it is relative to other goods.
- Other prices remain unchanged.
- The substitution effect is usually more important than the income effect.

OTHER PRICES, DEMAND DETERMINANT The prices of other goods that influence the decision to purchase a particular good, which are assumed constant when a demand curve is constructed. Other prices can be for goods that are either substitutes-in-consumption or complements-in-consumption. This is one of five demand determinants that shift the demand curve when they change. The other four are other prices, buyers' preferences, buyers' expectations, and number of buyers.

Today, you are likely to spend a great deal of time at an auction wanting to buy either a remote controlled ceiling fan or a how-to book on home decorating. Be on the lookout for slow moving vehicles with darkened windows.
