The Law of Downward-sloping demand:
People will purchase more of a good at a lower price, all other things equal (ceteris paribus)
Movements along the demand curve are known as
changes in the quantity demanded
The only factor that affects the quantity demanded
the price of the good/service in question.
Factors that affect the demand schedule (cause shifts of the demand curve)
Market size

New Inventions
Expectations

The substitution effect
When the price of one product changes, we either buy more (price drops) or substitute and spend on a different brand (price rises).

When the price of one product increases, we have less ability to buy that product.
