Q

PPF curve & efficiency

A

-any point on the PPF curve=using resources effeciently
-any point inside the PPF curve=inefficient
-any point outside the PPF curve=unattainable (can never happen)

Q

the law of comparative advantage:

A

the individual, firm, or country with the lowest opportunity cost of producing a particular good should specialize in producing that good

if you have lowest opp. cost means that you should specialize in that!

opp. cost only involves the 2nd best choice (DO THE THING YOU’RE BEST AT DOING!)

21
Q

substitutes:

A

A
when a fall in the price of one good reduces the demand for another good, the two goods are called subsitutes

*think: hot dogs and hamburgers

22
Q

complements:

A

when a fall in the price of one good raises the demand for another good, the two goods are called complements

*think: peanut butter & jelly!

23
Q

competitive market:

A

describes a market where there are so many buyers and so many sellers that each has a negligible impact on the market price

*think: each ice cream seller has limited control over the price b/c other sellers offering similar products

24
Q

2 characteristics of a perfectly competitive market:

A

-the goods offered for sale are all exactly the same
-the buyers & sellers are so numerous that no single buyer or seller has any influence over the market price

25
Q

price takers:

A

must accept the price that the market determines

26
Q

monopoly:

A

market that only has one seller that sets the price

27
Q

quantity demanded:

A

the amount of the good that buyers are willing and able to purchase

28
Q

Law of Demand:

A

other things being equal, when the price of a good rises, the quantity demanded of the good falls, and when the price falls, the quantity demanded rises

29
Q

Demand schedule:

A

a table that shows the relationship between the price of a good and the quantity demanded (holding everything else constant)

30
Q

Market demand:

A

the sum of all the individual demands for a particular good or service

31
Q

5 shifters of supply:

A

changes in:
-technology
-prices of inputs (relevant resources)
-number of producers
-producer expectations (about the future)
-weather

32
Q

change in quantity demanded:

A

a change in price results in a change in quantity demanded ONLY

33
Q

Law of supply:

A

when price increases, more products are produced and when price decreases, less products are produced

34
Q

change in quantity supplied:

A

a change in price changes quantity supplied ONLY

35
Q

the market conflict:

A

producers want to sell product at highest price & buyers want to buy at the lowest price

so, leads to negogiation

36
Q

shortage

A

exists when the quantity demanded of a good exceeds the quantity supplied at a given price

not enough of the good to satisfy demand of customers

37
Q

surplus

A

exists when the quantity supplied of a good exceeds the quantity demanded at a given price

too much of the good available

38
Q

equilibrium

A

occurs when price of good=quantity sellers are willing/able to supply

39
Q

consumer surplus=

A

the amount a buyer is willing to pay for a good minus the amount the buyer actually pays

40
Q

producer surplus=

A

the amount a seller is paid for a good minus the seller’s cost of providing it

41
Q

price floor:

A

the legal minimum price (price floor must be above equilibrium price to be effective)

often set by the government
*remember: floor goes high, ceiling goes low

basically it’s the lowest price you can charge

42
Q

price ceiling:

A

the legal maximum price (must be set below equilibrium price to be effective)

*remember: floor goes high, ceiling goes low!

43
Q

price elasticity of demand:

A

a measure of how responsive consumers are to price changes

44
Q

elasticity of demand=

A

% change in qty demanded/% change in price

basically use the midpoint formula!

elasticity of demand will always be negative!

45
Q

for a 1% change in the denominator (price)…

A

the numerator will change by the elasticity of demand %

46
Q

if the absolute value of elasticity of demand > 1

A

then the elasticty of demand is elastic, or very responsive to price changes

*raise price a little bit & lose lots of customers…

47
Q

if the absolute value of elasticty of demand=1

A

then elasticity of demand is unit elastic

48
Q

if the absolute value of the elasticity of demand < 1

A

then the elasticity of demand is inelastic, which means that consumers are not very responsive to price changes

*raise price a little bit & you won’t lose many customers!

49
Q

total revenue=

A

price * quantity

50
Q

inelastic demand

A

raise price & total revenue increases, lower price & total revenue decreases

51
Q

elastic demand

A

raise price & total revenue decreases, lower price & total revenue increases

52
Q

unit elastic

A

raise or lower price & total revenue stays the same
