13 Do you notice the point where supply and demand intersect?

14 Equilibrium  When creating a demand curve and a supply curve, there is a point where the curves intersect. This point is the equilibrium point.  Equilibrium occurs when the quantity demanded equals the quantity supplied.  A market is stable at equilibrium.

16 $40 $ QS=30 QD = 10 Surplus Q

17 $4 $ QS=80 QD=40 Surplus Q

18 $800 $ Shortage Q

19 If a seller has seven donuts on the shelf at $1 per donut, and consumers only want seven donuts at that price, then the market is at equilibrium.

20 Disequilibrium  A market is at disequilibrium when the quantity demanded does not equal the quantity supplied.  If quantity demanded is greater than quantity supplied, excess demand occurs.  If quantity supplied is greater than quantity demanded, excess supply occurs.

21 Low prices encourage consumers. Low prices can create excess demand.

22 Excess Demand  Excess demand occurs when the actual price is lower than the equilibrium price.  Low prices encourage demand.  To fix this problem, prices must be raised.

23 If every parent wants to purchase this toy for the holidays, excess demand can occur.

24 However, if no one is buying, then excess supply occurs.

25 Excess Supply  Excess supply occurs when quantity supplied is greater than quantity demanded.  The actual price is higher than the equilibrium price.  To fix this problem, prices must be lowered.

26 The day after Valentine’s Day, consumers will not pay high prices for Valentine’s candy.

27 Price Ceiling  A price ceiling is the maximum price that can be legally charged for a good or service.  The government interferes with market equilibrium when it creates a price ceiling.  Rent control is an example of a price ceiling.

28 Rent control is an example of a price ceiling.

29 Price Floor  A price floor is the minimum price that can be legally charged for a good or service.  The government interferes with market equilibrium when it creates a price floor.  Minimum wage is an example of a price floor.

30 The minimum wage is an example of a price floor.
