1. PRICE
Equilibrium: the point where demand and supply come together at the same price and quantity
At this point the
needs of both
consumers and
producers are in
balance

2. DISEQUILIBRIUM
Disequilibrium: when the quantity supplied and quantity demanded are not equal at the price offered.
One of two results will occur:
1. Excess demand
(Shortage)
2. Excess supply
(Surplus)

3. EXCESS DEMAND
Excess demand occurs when quantity demanded is greater than quantity supplied
This happens when the price of a good is
below the equilibrium price
Producers will
respond to this
shortage by
increasing the price
of the good

4. EXCESS SUPPLY
Excess supply occurs when quantity supplied is greater than quantity demanded
This happens when the price of a good is above the equilibrium price
Producers will respond
to this surplus by
decreasing the
price of the good

5. PRICE CEILINGS A maximum price set by law is a price ceiling
Price ceilings are placed on some ‘essential’ goods that some consumers wouldn’t otherwise be able to afford
Rent control is an example of a price ceiling
Zombies will attack oct

6. PRICE CEILINGS
Price ceilings are set below the market equilibrium price; therefore they result in excess demand
Price ceilings = shortage
(it is difficult to find an
apartment in a city
with rent control)

7. PRICE FLOORS A minimum price set by law is a price floor
Price floors are used to ensure that prices don’t fall so low a producer won’t get adequate reward for his/her efforts
Minimum wage is an example of a price floor

8. PRICE FLOOR
Price floors are set above the market equilibrium price; therefore they result in excess supply
Price floors = surplus
(there will be fewer
jobs for the # of workers
available)

quantity will be ________
lower, lower
