Q

why demand downslope?

Q

factors of demand

A

population- more people to demand shifts right

advertising- good then shifts right

substitute price- sub price increases demand shifts right

income - normal and inferior

fashion- if in fashion demand shift right

interest rates- borrowed money is cheaper so shifts right

compliment price- is complement cheaper shifts right

Q

factors of supply

A

productivity - more shifts right as cheaper costs

indirect tax - less means cheaper to produce shifts left

number of firms- more firms means more supply

technology- better tech less costs

subsidy- cheaper costs if more

weather- allows more supply (growing stuff)

costs of production

20
Q

equilibrium

A

when demand = supply so no excess ( allocative efficiency)

21
Q

price mechanism

A

eve if free market is not in equilibrium the market self corrects with its forces

22
Q

functions of free market

A

prices…

allocate scarce resources efficiently

ration scarce resources by encouraging or discouraging consumption

signal excess demand/supply and need to adjust allocation of resources

incentivise producers to increase or decrease output for profit max

23
Q

consumer surplus

A

difference between the price consumers are willing and able to pay and how much they do

24
Q

producer surplus

A

the difference between the price producers are willing and able to pay and how much they do pay

25
Q

society surplus

A

CS + PS

26
Q

joint demand

A

product / services that are bought together ( printer and ink)

27
Q

competitive demand

A

substitute goods (coke and pepsi)

28
Q

derived demand

A

when demand for one thing increases demand for its inputs increases

29
Q

composite demand

A

2 goods require the same input so when the production of 1 increases the others supply decreases (cheese and butter )

30
Q

joint supply

A

increase in production for 1 good increases the supply of another (steak and leather)

31
Q

ped formula and values

A

ped = %changeQd / %changeP

ped > 1 elastic
ped < 1 inelastic
ped = 0 perfectly inelastic
ped = 1 unit elastic
ped = infinity perfectly price elastic

32
Q

determinants of ped

A

substitutes (number)
percentage of income
luxury / necessity
Addictive
time period (short run inelastic as cant look for subs)

33
Q

pes equation

A

pes = %changeQs / %changeP

34
Q

determinants of pes

A

production lag ( more means inelastic as longer to react)

stocks (more stock means more elastic as can react to change in price)

spare capacity ( if more then more elastic can react to changes more)

substitutability of FOP (more = more elastic can react)

time( can react better in long run)

35
Q

xed formula

A

%changeQda / %changePb

36
Q

xed figures

A

+ sub
-compliment
xed > 1 strong relation
xed < 1 weak relation
xed = 0 no relation

37
Q

yed formula

A

yed = %changeQd / %changeY

38
Q

yed figures

A

+ Normal good
- inferior good

NORMAL
yed>1 income elastic (normal luxury)
yed< income inelastic (Normal necessity

INFERIOR
>1 income elastic
1<income inelastic

39
Q

business uses of PED

A

pricing decisions to maximise total revenue
prepare for increase in quantity for if elastic

40
Q

business use of PES

A

find ways to make supply price elastic so they can react to changes in price/demand

41
Q

business use of XED

A

pricing decisions such reducing price of first good and decreasing price of the second (reduce printer price increase printer ink price) or price against competitors.

cutting prices may cause price war so may show you to compete non price

if substitute don’t follow your price cut then you must be able to increase output and vice versa

42
Q

business use of YED

A

tells both responsiveness and type of good

plan for booms by knowing the effect of more income

be able to increase output if boom and demand increases

43
Q

limitations of elasticity

A

only ever estimates (sources of the data: surveys competitors and past data)

assumes ceteris paribus ( only one factor effects demand as demand may be effected by all elastticities)

ped varies along demand curve

44
Q

what is allocative efficiency (graphically)

A

allocative efficiency is at the social optimum ( msb = msc )

45
Q

where is the private optimum

A

mpc = mpb

46
Q

social costs (sc)?
private costs (pc)?
private benefits (pb)?
social benefits (sb)?

A
  1. SC = PC + EC
  2. Private costs are the producers costs of production
  3. Private benefit is the benefits of consumption
  4. SB = PB + EB
47
Q

maximisation of society surplus ?

maximisation of net social benefit?

A

demand = supply

MSB = MSC

48
Q
A
