Q

Give an example of overt collusion.

16
Q

Give the two factors on the interdependence of firms.

A
  • A firm’s behaviour is influenced by the actions of the firms around it
  • A firm’s behaviour is also influenced by how it feels other firms will perform in the future.
17
Q

What is game theory?

A

Game theory is an important model focusing on the behaviour of interdependent firms in an oligopolistic market.

18
Q

Give the three types of price competition in an oligopoly.

A
  • Price wars
  • Predatory pricing
  • Limit pricing
19
Q

Describe and explain price wars in an oligopoly.

A

Price wars is a form of price competition in an oligopolistic market, consisting of firms lowering their prices as much as possible to gain more market share or higher total revenue.

20
Q

What is predatory pricing?

A

Predatory pricing is a pricing strategy involving a large firm setting lower prices whenever a new entrant enters the market. Lower prices help attract more consumers, allowing the large firm to continue doing well. But this is an illegal strategy in UK and EU unless the firm restores its original price.

21
Q

What is limit pricing?

A

Limit pricing is a method involving the big firm setting as low a price to deter new firms from entering the market. Although the big firm will incur less supernormal profits in the short run, it is able to attract more consumers and thus retain its position in the monopoly. This means in the long term it will have stronger profitability.

22
Q

What is a pure monopoly?

A

Pure monopoly is a pure supplier of a good or service, hence claiming 100% market share; for example, National Rail is the only supplier of railway service in UK, so it claims 100% market share over the railway industry.

23
Q

What is a scale monopoly?

A

A scale monopoly is a market consisting of several suppliers of a good or service, each firm claiming about 25% of total market share.

24
Q

Give a characteristic of a monopoly.

A

Economies of scale

25
Q

Give another characteristic of a monopoly.

A

Dynamic efficiency - R&D firms improve capital and productivity of firms, leading to a lowering in LRAC curve.

26
Q

What is price discrimination?

A

Price discrimination involves a seller setting different prices for different consumers of the same good or service.

27
Q

What are the requirements for price discrimination?

A

Firms are price makers (they can change market price)

28
Q

What is another requirement for price discrimination?

A

The differing market segments (domestic, industrial users…) must have differing elasticity of demand.

29
Q

What is third-degree price discrimination?

A

This is a type of price discriminiation involving charging different prices of the same good or service to different groups of consumers; a theme park charges different prices to children and adults.

30
Q

Give an advantage of price discrimination.

A

Profit maximisation - Higher revenue can be gained from selling same volume of the good or service (consumer surplus is converted into revenue for seller)

31
Q

Give another advantage of price discrimination.

A

Less competition - In the inelastic demand (inelastic market), demand won’t be much affected so higher prices will be set. This allows the firm to incur more profits as a result, hence some of these profits can be invested into the elastic market, helping decrease prices. The fall in prices can attract consumers to the firm, helping drive out competitors from the market.

32
Q

Define a pure monopsony.

A

A pure monopsony is where there is one singular buyer in the market.

33
Q

Define a oligopsony.

A

An oligopsony is where there are few buyers in the market.

34
Q

What is monopsony power?

A

This is where a buyer faces little competition from other buyers for hiring labour, or obtaining a good or service; an example is healthcare, where most doctors of nurses are hired by the NHS, compared to small private healthcare firms.

35
Q

Give an advantage of monopsony to the monopsonists.

A

To the monopsonists, an advantage is higher profits as a result of buying at lower prices (firms are price makers).

36
Q

Give another advantage of a monopsony to a monopsonist.

A

Higher profits can be reinvested into the firm to improve innovation, capital which helps achieve economies of scale.

37
Q

Give an advantage of a monopsony to a consumer.

A

Lower costs faced by the monopsonist can be portrayed in the form of lower selling prices to consumers, strengthening consumer demand. But this is dependant on the price elasticity.

38
Q

Give an advantage of a monopsony to a supplier.

A

Suppliers have to focus on cutting costs to prevent being driven out of business, as they can’t cover average variable cost.
