Q

Factors influencing demand for labour

A

Wage rate (higher WR, lower demand), Demand for product (higher demand for product, higher demand), Productivity of labour,(higher productivity, higher demand(can be argued)), profitability of firms(higher profitability, higher demand), number of substitutes( cheaper machinery, lower demand), number of buyers of labour (less buyers, less demand)

Q

Elasticity of demand for labour in low skilled jobs

Q

Elasticity of demand for labour in high skilled jobs

A

Higher paying jobs, labour supply inelastic as often require more skill meaning less people are able to do them. Therefore, a change in wage sees little change in demand

Q

Problems of increasing the minimum wage

A

Increases unemployment, cost-push inflation, black market, poorest don’t benefit( those on benefits), limited impact on relative poverty ( those just above the poverty line become relatively poorer), regional variations in wage, higher wages passed into consumers, increased number of workers on minimum wage

Q

Problems of a monopsony

Q

Characteristics of Perfect Competition

A

Large number of firms, homogenous products, freedom of entry/exit, firms are price takers, each producer supplies small proportion of industry output, consumers and producers have perfect knowledge of the market

25
Long-run supernormal profit in perfect markets
Firms have freedom of entry/exit into the market, increase of supply so a fall in price. Returns to normal profit
26
Perfect Market Short-run loss minimisation
In short run, if revenue is greater than variable cost you should continue to produce
27
Monopoly Characteristics
1 firm in the industry, only 1 product, high barriers to entry/exit, firms are price setters, producers supply fill proportion of the output, imperfect knowledge
28
Problems with Monopolies
High price, lack of choice, poor quality, inefficient
29
Origins of a Monopoly
Growth of firm, merger/takeover, legal means, acquiring patents
30
Monopolies are allocatively inefficient because…
The price is higher than marginal cost
31
Monopoly is productively inefficient because…
They don’t produce at the lowest point on the AC curve
32
Monopoly is X-inefficient because…
they have no incentive to cut costs.
33
Monopoly long-run supernormal profit
Continues to make supernormal profit, leads to unequal distribution of wealth
34
Advantages of a Monopoly
Benefit from economies of scale so may be more efficient, better research and development, if grown organically may be more efficient, natural monopoly (may be better to just have one firm in the industry)
35
Price Discrimination
Charging a different price to a different group of people for the same good
36
Conditions needed for Price Discrimination
Firms must operate in imperfect conditions, firms must be able to separate tickets and prevent resale, different consumer groups must have elasticities of demand
37
Advantages of price discrimination
Firms able to increase revenue, increased revenues can be used for R and D, some consumers benefit
38
Disadvantages of Price Discrimination
Some consumers end up paying higher prices (allocatively ineffecient), decline in consumer surplus, increases inequality, administration costs, predatory pricing
39
Oligopoly
Where a few large firms dominate the industry
40
Feature of an oligopoly
Price may be stable, collusion potential, high concentration ratio, interdependence of firms, homogenous or highly differentiated goods, brand loyalty, non-price competition, high barriers to entry, game theory, Long run AC saucer shaped
41
Advantages of an oligopoly for consumers
Price wars, high levels of R and D (improved dynamic efficiency), economics of scale, high supernormal profits can be taxes
42
Disadvantages of an Oligopoly for consumers
Price fixing collusion, limits customer choice (high barriers to entry), persuasive advertising distorts the market, oligopolies can avoid paying tax
43
Shadow Pricing
Companies claim higher profits in countries with less tax
44
Conditions for contestable Markets
Access to all available technology, absence of sunk costs, low barriers to entry, low rate of customer loyalty
45
Hit and run entry
When a business enters an industry to take advantage of temporarily high profits
46
Sunk costs
Costs that can’t be recovered if a business decides to leave an industry - higher costs, less contestable markets
47
Barriers to entry in contestable markets
Sunk costs, levels of advertising/loyalty, access to supply of goods, access to technology and skilled labour
48
Methods to increase the contestability of markets
Removal of legal barriers to entry, force firms to allow competitors to use its network, ban predatory pricing, CMA investigate on the use of predatory power
49
Characteristics of monopolistic competition
Large number of firms, firms have little control over price, few barriers to entry and exit, imperfect knowledge
50
Organic growth
When a firm chooses to grow from within
51
External growth
Growing the business by either merging or taking over another business
52
Benefits of external growth
Allows consumer cheaper prices, allows companies to keep the best staff
53
Problems of external growth
May cause principal-agent problem as workers aren’t interested in another company, may lose customers if other brand is poor
54
Conglomerates
When a firm had a merger or a takeover with a firm who they have nothing in common with
55
Fixed and Variable costs
Fixed costs don’t change with output, variable costs change with output
56
Deserters
When two firms who had previously joined decide to split
57
Economies of scale
The more you produce, the cheaper the product becomes
58
Types of economies of scale
Production, Purchasing, Financial, Marketing, Managerial, Risk bearing
59
Diseconomies of scale
When firms get too big, AC starts rising again
60
economies of scale
The more the industry produces, the cheaper each product becomes
61
Allocative Efficiency
Efficiency which markets are allocating resources - allocatively efficient for producing the right goods for the right people at the right price
62
Productive efficiency
Where a firm produces at the lowest point on its AC curve
63
X-inefficieny
When firms don’t have incentives to cut costs, so costs end up being higher than they should be
64
Technical efficiency
When a firm is producing the maximum output from the minimum quality of inputs
65
Dynamic efficiency
Measures the extent to which various forms of static efficiency improve over time
66
Limit Pricing
Charge below the average cost of your rivals
67
Predatory Pricing
Charge a price to force new rivals out
68
Revenue Maximisation
Pricing in order to bring in considerable revenue
69
Profit Maximisation
Pricing to satisfy the shareholders by making as much profit this accounting year
70
Normal Pricing
Pricing to cover your ATC
71
Price War
Constantly undercutting your equally powerful rival
72
Sales Volume Pricing
Charging a price where AR=AC
73
Non-price strategies
Competing against direct rivals, but on areas other than price
74
Collusion
When two or more firms agree to manipulate the market for their own self interest
75
Factors of collusion
Charge the exact same amount, agree not to compete against each other, agree not to compete on location
76
Reasons to collude
Increase profits, protect market share, reduce costs such as advertising, avoid having to open new shops
77
Price capping
When firms are only allowed to charge up to an agree maximum price
78
Regulators
Government set up an independent body who regulate a natural monopoly
79
Water Regulators
Ofwat - set targets that hold water companies to high standards
80
Natural Monopoly
A natural monopoly exists because the cost of producing the product is lower if there’s just a single producer than if there
81
Problems with a natural monopoly
Monopsony power - force producers out of business , same as monopoly problems
82
Public Private Partnership
Contractors pay for the construction then rent the good back to the public sector
83
Positives of a public private partnership
Government gets new infrastructure without paying taxes, expert building and running of the operation
84
Negatives of Public Private Partnership
Profit focused firms so poorer quality, moral issues, government make a loss eventually (more taxes being paid)
85
Profit capping
Capping the amount of supernormal profit a firm is allowed to earn
86
Positives of profit capping
Incentive to keep quality high, reduces inequality, firms can’t exploit consumers, firms still make profits, firms forced to be x-inefficient
87
Windfall tax
A one off additional tax on firms supernormal profits
88
Deregulation
A reduction or elimination of government power in a particular industry
