Demand Schedule
A table that shows the relationship between the price of a good and the quantity demanded
Market Demand
The sum of all individual demands for a good or service... basically the process of horizontally adding
Market Demand Curve
Sum the individual demand curves horizontally... to find the total quantity demanded at any price, we
add the individual quantities, in doing so we arrive at market quantity demanded
The Demand Curve
Shows how price affects quantity demanded, other things being equal
What are "other things" when talking about the demand curve
They are the non price determinants of demand... these are the things that determine buyers' demand
for a good, other than the good's price. These cause a SHIFT in the D curve
