Q

Disadvantages of maximum price?(3)

A

creates excess demand therefore shortage,firms can leave the market as profit maximisers (leading to less options and potentially lower quality goods), could create a black market

25
Factors which affect Ped?(4)
availability of subsititutes, time, proportion of income, whether good is luxury or necessity
26
Xped?
Measures the responsiveness of quantity demanded of good A to a change in price of good B.
27
Factors of monopolistic competition? (5)
product differentiation, price making power, elastic demand curve, barriers to entry and exit are low and low concentration ratio
28
Factors affecting pes?(4)
time,raw materials needing to be extracted, availability of spare capacity, ability to alter production methods
29
Marginal cost?
extra cost when producing one more unit
30
Causes of market failure?(6)
Imperfect information, public goods, merit and demerit goods, externalities, inequalities in wealth and income, factor immobility
31
3 conditions for price discrimination?(3)
Price maker (monopoly, market power), limit reselling and have information about consumers ped
32
Economies of scale barrier to entry explanation?
Incumbent firms can keep their prices low and costs creating a barrier to entry as new small firms cannot enter the market and compete or price
33
What shifts the ppf outwards? (5)
improvements in technology, introduction of new resources, increased productivity, increased supply of labour through immigration, improvements in education and training
34
Examples of anticompetitive practices?
Collusion, predatory pricing and vertical integration
35
Predatory pricing?
36
Productive efficiency?
Maximising output at lowest point of AC curve, full exploitation of economies of scale
37
Examples of barriers to entry? (4)
high start up costs, sunk costs, high MES and laws and regulations
38
Privatisation?
When the government sells state owned company to the private sector as it has become x inefficient- no profit incentive
39
Collusion definition?
When two or more firms come together to limit competition
40
Examples of government intervention?(6)
subsidies, price controls, taxes, regulation, advertisement, state provision
41
3 main examples of government failures occurring?
imperfect information, unintended consequences, enforcement costs very high (subsidies, price controls)
42
What efficiency are firms in perfect competition?
static (productively and allocatively)
43
What does dynamic efficiency require?
Supernormal profit so firms lack the means
44
Monopolistic competition definition?
A market with many firms selling slightly different products
45
What happens to monopolistic firms supernormal profit in the long run?
Gets eroded away as new firms enter the market due to low barriers to entry and knowledge widely available. Leads to a shift left of demand as more choice for consumers from other firms.
46
characteristics of a perfect competitive market?(4)
many buyers and sellers, homogenous products, no barriers to entry and exit, sellers and buyers have perfect knowledge
47
Characteristics of a Monopoly?(5)
Price maker as only one firm (100% market share), high barriers to entry and exit, supernormal profits in the short run and long run, differentiated products and imperfect information
48
Contestable markets?
low barriers to entry and exit
49
monopolistic competition?
many sellers with price setting powers
50
What profits are possible in the short and long run in monopolistic competition?
short run- supernormal profits long run-normal profits as supernormal profits eroded away (low barriers to entry)
51
Define Consumer surplus?
the difference between the price consumers and willing/able to pay for a good/service and the price they actually pay
52
Define producer surplus?
The difference between the price producers are willing and able to s
53
internal economies of scale? (6) RMFPTM
technological, financial, purchasing, marketing, managerial and risk bearing
54
What is internal economies of scale?
when firms become larger and average costs fall with increased output
55
external economies of scale? (2)
more training facilities and roads improved
56
Inelastic number?
below 1
57
elastic number?
above 1
58
Monopoly power definition?
When a firm has the ability to set prices (price makers)
59
Monopolistic competition features?
many small buyers and sellers, low barriers to entry and exit, price makers
60
Deregulation definition?
Removing regulations from markets lowering barriers to entry and encouraging competition
61
Factors which affect elasticity of labour demand?(3)
time, substitutes and % of total cost
62
What type of demand is for products which take a high proportion of your income ?
Elastic as expensive goods consumers shop around for the best price
63
64
Regressive indirect tax eval?
Tax takes greater proportion of income of poor than rich so overuse indirect tax promotes more unequal distribution of income which is a market failure and leads to government intervention.
65
Law of diminishing returns definition?
When a variable factor of production increases while others stay fixed (short run)
66
Barriers to entry examples (4)
sunk costs, economies of scale, brand loyalty and patents,
67
Monopoly evaluation?
dynamic efficiency? give profit to shareholders via dividens, save it or pay off debts or workers higher wages so not necessarily reinvested, DOS- size of firm, objective of monopoly assume its profit max but what if sales max?, type of good-luxury good we can pay higher prices for
68
Cons of monopolies?(4)
x inefficiency, allocative inefficiency, productive inefficiency and inequalities in necessity markets (food and drink lower income won't afford)
69
Pros of monopolies?(3)
dynamic efficiency, usage of economies of scale large size ( car market), cross subsidisation (large profits can subsidise loss making good
70
Profit satisficing?
When a firm makes enough profit to satisfy influencers and stay in the market but may pursue other objectives
71
Marginal physical product of labour?
Amount of output produced by each extra worker
72
Marginal revenue product? (MRP)
extra revenue an additional worker brings in
73
Labour market shifts?(
migration, income tax and benefits, cost of capital,
74
Where does a monopsonist profit maximise?
Where MCL=ACL
75
Labour market failure?
occupational immobility (labourers lack the skills for new jobs hence becoming structurally unemployed), geographical immobility
76
Wage differential definition?
Wage rates differ due to economic factors such as MRP, elasticity of labour supply
77
Complete market failure?
When good would not be provided without government intervention (public good)
78
Contestable markets?
When there is the threat of competition in a market- features are competitive market features
79
Diminishing marginal utility?
As you consume more of one good the satisfaction will decrease from each extra good consumed
80
4 main causes of government failure?
Law of unintended consequences, imperfect information, administration costs and distortion of the price mechanism
