Q

Advantages Of Contestability

A
  • Incentive to keep costs down (reduced X-inefficiency)
  • Non Price Competition means that firms who can’t reduce prices can still compete

16
Q

Disadvantages Of Contestable Markets

A

-Limited dynamic efficiency improvements as not all firms make supernormal profits
-Allocatively inefficient (MC ≠ P) so consumers face a loss in their consumer surplus

17
Q

Examples Of Each Market

A

Perfect Competition - Currency Exchange, Wheat
Monopoly - Tesco, Apple
Oligopoly - Smartphone Network Providers
Monopolistic Competition - Restaurants, Hair Salons
Contestable Markets - Electricity Suppliers and Retail Stores

18
Q

Natural Monopoly

A

Where a monopoly naturally arises

Huge sunk costs and economies of scale make it more efficient for one firm to run the industry

19
Q

Advantages of natural monopoly

A

High supernormal profits for R&D
One firm has large amount of capital which can be used for purchasing economies of scale leading to a reduced consumer price (potential)

20
Q

Disadvantages of a natural monopoly

A

Lack of incentive to be efficient and potential poor management (X-inefficiency)
Price is significantly above P=MC so there is allocative inefficiency
Firm may be heavily regulated which may reduce SNP

21
Q

How does a monopoly obtain price setting power?

A

A monopoly has price-setting power because it is the sole supplier in the market and faces no close substitutes.

High barriers to entry prevent new firms from entering, so the monopolist faces the market demand curve directly.

This allows it to choose the profit-maximising price and output, rather than being a price taker like in perfect competition.

22
Q

Why does a firm in perfect competition have no price setting power?

A

The goods are identical meaning if a firm raises their prices, their consumers will switch to one of the other firms.

The competition between the many firms drives prices down to the point where p=mc, meaning a further reduction in price would cause losses.

23
Q

Why do firms in an oligopoly have some price setting power?

A

A few large firms dominate the market, leading to interdependence and strategic behaviour

Firms use high market share to influence price as their market share is large enough to the extent where their pricing decisions affect market outcomes.

Prices are sticky due to fear of price wars, and firms may avoid lowering prices even if MC < P.

24
Q

Why does a higher market share allow for greater price control?

A

A higher market share gives firms more control over market supply, allowing them to set prices. They can also influence competitors’ pricing and benefit from economies of scale, reducing costs and maintaining profitability at higher prices.

25
Advantages Of A Monopsony
- Reduced supply costs can reduce the costs the consumer pays (increasing consumer utility) - Reduced supply costs can increase profits of a firm for R&D - Firms can ensure greater control over suppliers (dictate contract terms and quality standards)
26
Disadvantages Of A Monopsony
Lower Wages (can increase inequality and worsen living standards) Reduced Supplier Profits reduce the ability to invest in R&D (for supplier) Efficiency Wage Theory Suppliers may cut costs to survive the reduced revenue - leading to a worsening quality of goods and services
27
Advantages Of Nationalisation
Services are provided at cost and not for profit - increasing affordability (crucial for merit good) Externalities can be prevented as the government can produce at a point that maximises social welfare Governments are less likely to cut jobs for short term profits ALLOCATIVE EFFICIENCY (CHARGE WHERE P=MC) Natural Monopoly Efficiency (High sunk costs and low marginal costs mean that economies of scale are best exploited with single provider)
28
Disadvantages Of Nationalisation
X-Inefficiency (no profit motive creates less of an incentive to cut costs and produce as efficiently as possible Dynamic Inefficiency without competition Governments may care more about re-election than efficiency so they may keep a failing factory open for voting support - causing market distortion by allowing inefficient firms to allocate resources
29
Advantages Of Privatisation
Increased Dynamic Efficiency through retained profits and reduced X-inefficiency Improved quality and consumer choice through competition Reduced fiscal burden to the government (often nationalised industries obtain debt due to x-inefficiencies) which allows for money investment into capital spending and education
30
Disadvantages Of Privatisation
Firms aim to maximise profits and not social welfare, causing P>MC which reduces consumer surplus and social surplus NO ALLOCATIVE EFFICIENCY Externalities may arise as the firms do not produce at the socially optimal point (MSB=MSC) and will produce where (MR=MC) which can cause an over/under consumption of resources
31
Advantages Of Regulation
Can mitigate monopoly power by preventing exploitative pricing Promotes Competition (improving quality and leading to reduced prices) + reduces X-inefficiency Can implement safety standards to ensure goods are of sufficient and consistent quality
32
Disadvantages Of Regulation
Regulatory Capture (regulators act in the interest of the industry and not consumers) Excessive profit caps and competition policy reduce SNP for R&D (harms dynamic efficiency, leading to higher costs in the long run, causing long run higher prices) Price Controls can cause shortages and subsidies can cause overproduction (waste of resources that could have been used elsewhere)
33
Competitive Tendering
When the government or large firms invite bids from suppliers to provide goods and services, selecting the best offer based on price, quality and efficiency
34
Advantages Of Competitive Tendering
Competition to win the bid drives down prices, allowing the government to have more money to spend elsewhere Firms innovate to win bids as the higher quality of the goods/service will make the bid more competitive to the government Access to expertise, governments can hire specialists leading to more efficient management which can reduce X-inefficiency and eliminate bureaucratic inefficiencies by outsourcing to specialists and allow the quality of the final good to be optimal
35
Disadvantages Of Competitive Tendering
Firms may sacrifice quality for a low price as in order to offer a low price and stay profitable, the firm must keep costs low meaning the firm may not use expensive but efficient technologies (this can lead to,safety hazards and negative externalities) Risk Of Corruption - Government contracts may favour politically connected firms, meaning the firm that can produce most efficiently may not the bid, meaning the taxpayer pays an unnecessarily high price
