Substitutes, Complements, Normal, Inferior

The idea
Substitutes can replace one another, more of one, less of the other; complements are used together, more of one, more of the other. A normal good's quantity demanded rises with income; an inferior good's falls as income rises. All four are demand shifters.
In practice
Tea and coffee; coffee and cream; steak and noodles.
Where people slip
Inferior describes income response, not quality.
