common sense
substitution effect & income effect
maximize utility
Substitution Effect
willingness to buy is effected. The change in quantity demanded of a good that results from a change in price, making the good more or less expensive relative to other goods that are substitutes.

Ceteris Paribus Condition
“all else equal” The requirement that when analyzing a relationship between two variables such as price and quantity demanded, all else must be held constant
Change in quantity demanded
movement along the same demand curve. Can only be caused by a change in that products own price
Change in demand
shift in the entire demand curve left(decrease) or right(increase) caused by some factor other than that products own price
Things that cause demand to shift
income prices of related goods consumer taste or preferences population expectations of consumers
Income
two types of goods: normal and inferior
normal-a good which demand increases as income rises.
inferior-a good which demand increases as income falls
Price of Related Goods
substitutes-price of one good increases, demand for the other will increase
complementary-price of a complement decreases, demand for the other will increase
Consumer taste or preferences
taste increases, demand for that product will increase
Population
As population increases, the demand for most products will increase
Expectations of consumers
