demand schedule
table that shows the relationship between the price of a product and the quantity of the product demanded
demand curve
curve that shows the relationship between the price of a product and the quantity of the product demanded
ceteris paribus “all else equal” condition
requirement that when analyzing the relationship between two variables such as price and quantity demanded - other variables must be held constant
quantity demanded
amount of a good/service that a consumer is willing and able to purchase at a given price
law of demand
rule that states holding everything else constant when the price of a product falls, the quantity demanded of the product will increase and when the price of a product rises, the quantity demanded of the product will decrease
what explains the law of demand?
- consumers substitute towards the good when the price has fallen.
- consumers have more purchasing power; increase in income
substitution effect
change in the quantity demanded of a good that results from a change in price making the good more or less expensive relative to other goods, holding constant the effect of the price change on consumer purchasing power
income effect
change in the quantity demanded of a good that results from the effect of a change in the goods price on a consumers purchasing power, holding other factors constant.
a change in something other than PRICE that AFFECTS demand causes the entire demand curve to shift
A shift to the RIGHTis an INCREASE in demand.
A shift to the LEFT is a DECREASE in demand
as the demand curve shifts, the quantity demanded will change even if the price doesn’t
quantity demanded changes at every price
variables that shift market demand
income prices of related goods tastes population and demographics future prices
income demand
increase in income increases demand if product is normal, decreases demand if product is inferior
prices of related goods in demand
increase in price of related good increases demand if products are substitutes, decreases demand if products are complements
