Advantages and disadvantages of monopolies

What are the advantages and disadvantages of monopolies?

Monopolies are firms who dominate the market. Either a pure monopoly with 100% market share or a firm with monopoly power (more than 25%) A monopoly tends to set higher prices than a competitive market leading to lower consumer surplus. However, on the other hand, monopolies can benefit from economies of scale leading to lower average costs, which can, in theory, be passed on to consumers.


Disadavantages of monopolies

  1. Higher prices than in competitive markets – Monopolies face inelastic demand and so can increase prices – giving consumers no alternative.
  2. A decline in consumer surplus. Consumers pay higher prices and fewer consumers can afford to buy. This also leads to allocative inefficiency because price is greater than marginal cost.
  3. Monopolies have fewer incentives to be efficient. With no competition, a monopoly can make profit without much effort, therefore it can encourage x-inefficiency (organisational slack)
  4. Possible diseconomies of scale. A big firm may becomes inefficient because it is harder to co-ordinate and communicate in a big firm.
  5. Monopolies often have monopsony power in paying a lower price to suppliers. For example, farmers have complained about monopsony power of large supermarkets. A monopoly may also have the power to pay lower wages.
  6. Monopolies can gain political power and the ability to shape society in an undemocratic and unaccountable way – especially with big IT giants who have such an influence on society and people’s choices.

In the late nineteenth-century, large monopolist like Standard Oil gained a notorious reputation for abusing their power and forcing rivals out of business. This led to a backlash against monopolists. But, in the Twenty-First Century, there are new monopolies which have an increasing influence on people’s lives.

Potential advantages of monopolies

  1. Economies of scale. In an industry with high fixed costs, a single firm can gain lower long-run average costs – through exploiting economies of scale. This is particularly important for firms operating in a natural monopoly (e.g. rail infrastructure, gas network). For example, it would make no sense to have many small companies providing tap water because these small firms would be duplicating investment and infrastructure. The large-scale infrastructure makes it more efficient to just have one firm – a monopoly.

    Note these economies of scale can easily outweigh productive and allocative inefficiency because they are a greater magnitude.

  2. Innovation. Without patents and monopoly power, drug companies would be unwilling to invest so much in drug research. The monopoly power of patent provides an incentive for firms to develop new technology and knowledge, that can benefit society. Also, monopolies make supernormal profit and this supernormal profit can be used to fund investment which leads to improved technology and dynamic efficiency. For example, large tech monopolies, such as Google and Apple have invested significantly in new technological developments.
    • However, this can also have downsides with drug companies able to charge excessively high prices for life-saving drugs. It also gives drug companies an incentive to push pharmaceutical treatments rather than much cheaper solutions of promoting good health and avoiding the poor health in the first place.
  3. Firms with monopoly power may be the most efficient and dynamic. Firms may gain monopoly power by being better than their rivals. For example Google has monopoly power on search engines – but can we say Google is an inefficient firm who don’t seek to innovate?

Evaluation of pros and cons of monopolies

  • It depends whether market is contestable. A contestable monopoly will face the threat of entry. This threat of entry will create an incentive to be efficient and keep prices low.
  • It depends on ownership structure. Some former nationalised monopolies had inefficiencies, e.g. British Rail was noted for poor sandwich selection and some inefficiencies in running the network. However, this may have been partly monopoly power but also the lack of incentives for a nationalised firm.
  • It depends on management. Some large monopolies have successful management to avoid the inertia possible in large monopolies. For example, Amazon has grown by keeping small unit of workers who feel a responsibility to compete against other units within the firm.
  • It depends on the industry. In an industry like health care there are different motivations to say banking. Doctors and nurses do not need a competitive market to offer good service, it is part of the job.
  • It depends on government regulation. If governments threaten price regulation or regulation of service, this can reduce the excesses of some monopolies.
  • Environmental factors – A monopoly which restricts output may ironically improve the environment if it lowers consumption.
  • It depends how you define the industry. It also depends how you define a monopoly. A domestic monopoly in steel may still face international competition. Eurotunnel faces a monopoly on trains between UK and France but it faces competition from other methods of transport – planes and boats.

Advantages of being a monopoly for a firm

Firms benefit from monopoly power because:

  1. They can charge higher prices and make more profit than in a competitive market.
  2. The can benefit from economies of scale – by increasing size they can experience lower average costs – important for industries with high fixed costs and scope for specialisation.
  3. They can use their monopoly profits to invest in research and development and also build up cash reserves for difficult times.

Why governments may tolerate monopolies

  1. It is difficult to break up monopolies. The US government passed a lawsuit against Microsoft, suggesting it should be split up into three smaller companies but it was never implemented.
  2. Governments can implement regulation of Monopolies e.g. OFWAT regulates the prices for water companies. In theory, regulation can enable the best of both worlds – economies of scale, plus fair prices. However, there is concern about whether regulators do a good job – or whether there is regulatory capture with firms gaining generous price controls.
