26
6 Economic goals
Freedom efficiency (allocation of scarce resources) equity (what is "fair") security (protect consumers, producers from risk) stability (maintain stable prices) growth (increasing production of goods)
27
Equilibrium
refers to a situation in which the price has reached the level where quantity supplied equals quantity demanded
28
Equilibrium Price
the price that balances quantity supplied and quantity demanded
29
Equilibrium Quantity
the quantity supplied and the quantity demanded at the equilbrium price
30
Law of supply and demand
The claim that the price of any good adjusts to bring the quantity supplied and the quantity demanded for that good into balance Everything will balance out
31
Surplus
When price is greater than the equilibrium price
32
Shortage
When price is lower than equilibirum price
33
Price ceiling
a legal maximum on the price at which a good can be sold
34
Price floor
a legal minimum on the price at which a good can be sold
35
When is price ceiling binding?
When it is set below the equilibrium price
36
When is price floor binding?
When it is set above the equilibrium price
37
Who do price ceilings benefit?
Good for buyers and bad for sellers
38
What does price ceilings create?
Shortages
39
What does price floors create?
Surpluses
40
Black market
Underground market Completely illegal
41
Gray market
Unauthorized, but not completely illegal Ex: babysitting
42
Agricultural price support program is an example of
A price floor
43
Elasticity
a measure of how much buyers and sellers respond to changes in market conditions
44
Demand elasticity
indicates the extent to which changes in price cause changes in the quantity demanded
45
Price elasticity of demand
measure of how much the quantity demanded of a good responds to a change in the price of that good
46
Price elasticity of demand formula
% change in QD/ %change in price
47
What makes a good elastic?
Luxury Specialized market Available substitutes Long run time horizon
48
What makes a good inelastic?
Short run time horizon Neccessity General market Less substitutes available
49
Inelastic demand
Quantity demanded does not respond strongly to price changes <1
50
Elastic demand
Quantity demanded responds strongly to changes in price >1
51
Perfectly inelastic demand
Quantity demanded does not respond to price changes Vertical line
52
Perfectly elastic demand
Quantity demanded changes infinitely with any change in price Horizontal line
53
Unit elastic
Quantity demanded changes by the same percentage as the price
54
Total revenue
the amount paid by buyers and recieved by sellers of a good
55
total revenue formula
TR= P*Q Q=quantity sold
56
When does total revenue increase?
With inelastic demand, when an increase in price leads to a no/very small decrease in quantity demanded
57
When does total revenue decrease?
With elastic demand, an increase in price leads to a decrease in quantity demanded
58
Necessities: Inelastic or elastic?
Inelastic
59
Luxuries: Inelastic or elastic?
Elastic
60
Price elasticity of supply formula
% change in QS/ % change in price
61
Determinants of the elasticity of supply
Ability of sellers to change the amount of the good they produce Time period
62
Ability of sellers to change amount of goods they produce
Beach front land=inelastic supply Books, card=elastic supply
63
Time period and supply
Supply is more elastic in the long run
64
Cross-price elasticity of supply
A measure of how much the quantity demanded of one good responds to a change in the price of another good
