when supply levels were higher than demand, prices were significantly reduced, lowering the profits realized by merchants. When merchants made less money, they could not afford to pay workers, resulting in high unemployment
James Steuart
Concept of supply and demand as part of a discussion about interest rates in 17th-century England
The price of any commodity rises or falls, by the proportion of the number of buyers and sellers."
JohnLocke

GOODS THAT ARE CONSUMED TOGETHER
Complements good
GOODS WHERE YOU CAN CONSUME ONE IN PLACE OF THE OTHER
Substitute goods
WHEN THE PRICE OF A GOOD THAT COMPLEMENTS A GOOD DECREASES, THEN THE QUANTITY DEMANDED OF ONE INCREASES AND THE DEMAND FOR THE OTHER INCREASES.
WHEN THE PRICE OF A SUBSTITUTE GOOD DECREASES, THE QUANTITY DEMANDED FOR THAT GOOD INCREASES, BUT THE DEMAND FOR THE GOOD THAT IT IS BEING SUBSTITUTED FOR DECREASES.
A normal good is a good that experiences an increase in its demand due to a rise in consumers'income.
Inferior goods are the opposite of normal goods. Inferior goods are goods that see their demand drop as consumers' incomes rise.
THE LAW OF SUPPLY
