Law of Supply and Demand

Demand and Supply

• The demand curve represents the relationship between the price of a good and the quantity of the good that consumers are willing and able to purchase.

Law of Demand

• The law of demand states that as the price of a good increases, the quantity demanded of that good decreases, ceteris paribus (all other things being equal).

Demand Schedule

• A demand schedule reflects the various quantities of a good that consumers are willing to buy at different prices.

Quantity Demanded

• The quantity demanded is the amount of a good or service that consumers are willing and able to purchase at a given price level.

Substitute Goods

• Substitute goods are products that can be used in place of each other, such as coffee and tea.

Law of Supply and Complementary Goods

• The law of supply relates to complementary goods, which are products that are used together, such as peanut butter and jelly.

Veblen Goods

• Veblen goods are luxury goods for which demand increases as the price increases, due to their exclusivity and prestige.

Equilibrium Price

• When the quantity demanded equals the quantity supplied, the market reaches equilibrium, and the equilibrium price is established.

Income Effect

• The income effect refers to the change in individual purchasing power resulting from a price change, leading to a change in the quantity demanded.

Disequilibrium

• Disequilibrium in a market occurs when the quantity demanded does not equal the quantity supplied, resulting in a surplus or shortage.
