A relationship between the price of a good and the quantity that consumers are willing and able to pay during a given period (o.t.c.)
Law of Demand
The quantity of a good demanded during a given period relates inversely to its price (o.t.c.)
Substitution Effect of a Price Change
When the price of a good falls, consumers substitute that good for other goods, which become relatively more expensive
Money Income

Income Effect of a Price Change
A fall in the price of a good increases consumer’s real income making consumers more able to purchase goods; for a normal good, the quantity demanded increases
Normal Good
A good, such as new clothes for which demand increases, or shifts rightward, as consumer incomes rise
Demand Curve

Inferior Good

Complements
Goods, such as milk and cookies, that are related in such a way that an increase in the price of one shifts the demand for the other leftward
Tastes
