6.1 Combining Supply and
Demand Notes
We’ve learned about supply and demand. Now, let’s put the concepts
together!
2
I. Balancing the Market
 Equilibrium: the point at which quantity
demanded and quantity supplied are equal or
$When the buyer will purchase exactly as much as sellers are willing to sell
3
II. Disequilibrium
 Disequilibrium: any price or quantity not at equilibrium
 Excess demand: when quantity demanded is more
than quantity supplied
example: when something sells out quickly (like digital
cameras on Black Friday), there is excess demand.
 Excess supply: when the quantity supplied is more than
the quantity demanded. $A market in equilibrium that
gets an increase in supply will experience quantity
supplied exceeding quantity demanded, so the price
will drop. example: Shoe City sold Nike at the equilibrium
price of $50, Shoe Town moves in next door and also sells at
$50. Now there is too much Supply, so the Price must drop

III. Government Intervention
Sometimes government can create a price ceiling, or a
maximum price that can be legally charged for a good or
service. $ Price ceilings are used on goods that are
essential but to expensive for some consumers.
$One example is rent control, a price ceiling placed on
rent. In New York City, rent was being raised like crazy, so
the government started rent control to keep the prices from
getting out of control.
Is rent control a
good thing or a
bad thing?
6
Bad parts of rent control:
 Rent control makes apartments so cheap that
there is excess demand. They don’t have
enough apartments to met demand.
 Rent control reduces the quality of housing
(more slums).
 Landlords know they can’t make much
money, so they don’t take care of the
maintenance.
 Because many apartment buildings aren’t
making money, they get converted to offices.
 Economists argue that rent controls do
more bad than good.

IV. Price Floors
 Price floor: a minimum price for a good or service
example: $ minimum wage, a minimum price that
an employer can pay a worker for an hour of
labor.
