Tables that show the relationship between the price of a product and the quantity of the product demanded are called demand schedules.
The amount of a good or service that a consumer is willing and able to purchase at a given price is called the quantity demanded.
Market demand is the demand by all the consumers of a given good or service.
Demand curve shows the relationship between the price of a product and the quantity of the product demanded.
When the price of a product falls, consumers buy a larger quantity because of two effects:
Market demand is the demand by all the consumers of a given good or service.
Demand curve shows the relationship between the price of a product and the quantity of the product demanded.
When the price of a product falls, consumers buy a larger quantity because of two effects:
- The income effect of a price change refers to the change in the quantity demanded of a good that results because a change in the good’s price increases or decreases consumers’ purchasing power. Purchasing power is the quantity of goods a consumer can buy with a fixed amount of income.
- The substitution effect refers to the change in the quantity demanded of a good that results because a change in price makes the good more or less expensive relative to other goods that are substitutes.
Ceteris paribus condition to refer to the necessity of holding all variables other than price constant in constructing a demand curve.
Variables That Shift Market Demand
The amount of a good or service that a firm is willing and able to supply at a given price is the quantity supplied.
When the price of a good rises, producing the good is more profitable, and the quantity supplied will increase. When the price of a good falls, selling the good is less profitable, and the quantity supplied will decrease.
A supply schedule is a table that shows the relationship between the price of a product and the quantity of the product supplied.
A supply curve shows the relationship between the price of a product and the quantity of the product supplied.
The law of supply states that, holding everything else constant, increases in price cause increases in the quantity supplied, and decreases in price cause decreases in the quantity supplied.
If only the price of the product changes, there is a movement along the supply curve, which is an increase or a decrease in the quantity supplied.
If any other variable that affects the willingness of firms to supply a good changes, the supply curve will shift, which is an increase or a decrease in supply.
Variables That Shift Market Supply
A change in quantity supplied refers to a movement along the supply curve as a result of a change in the product’s price.
Markets that have many buyers and sellers are competitive markets, and equilibrium in such markets is called competitive market equilibrium.
When the quantity supplied is greater than the quantity demanded, there is a surplus in the market.
When the quantity demanded is greater than the quantity supplied, there is a shortage in the market.
Variables That Shift Market Demand
- Income
- Prices of related goods
- Tastes
- Population and demographics
- Expected future prices
- Natural disasters and pandemics
