(From most competitive to least competitive)
Perfect Competition
Monopolistic Competition
Oligopoly
Monopoly
Perfect competition
Lots of small sellers
Identical products (don’t advertise)
Each seller has no ability to affect price
Easy for a new company to enter the market
Monopolistic Competition
Lots of small sellers
Differentiated products (advertise)
Each seller has no ability to affect price
Easy for a new company to enter the market
Oligopoly
A few, very large sellers
Differentiated products (advertise)

Law of Demand
As price goes up, quantity demanded goes down.
Quantity Demanded
The amount demanded at one price (a point on the curve)
Demand
The amount demanded at all prices (the curve itself).
What changes QD?
A change in the price of the product
What changes D?
Change in # of consumers
Change in consumer incomes.
Change in consumer t / p / e
Change in a substitute
Change in a complement
Quantity Supplied

Supply

Law of Supply
As price goes up, QS goes up.
What changes QS?
A change in the price of the product.
What changes S?
Government regulations
Technology
Inputs – changes in resources
Number of Sellers
Surplus
Surplus – QS > QD (too much)
Shortage
Shortage – QS < QD (not enough)
Price Floor
Lowest legal price; goes above equilibrium and causes surplus (minimum wage)
Price Ceiling
Highest legal price; goes below equilibrium and causes shortage (rent control)
