Intervention to Control Mergers

  • The Competition & Markets Authority (CMA) is the UK Government regulator tasked with ensuring that the creation of monopoly power is avoided & that consumers are not exploited in markets
    • The main forms of consumer exploitation include higher prices, less choice and/or poor quality products
  • There are similar regulators in Europe (European Competition Commission) & in the USA (Antitrust Commission)
  • One way to control monopoly power is to prevent it from forming in the first place
  • A key function of the CMA is to monitor merger activity with the aim of preventing any single firm gaining more than 25% market share
    • If there are concerns about the merger then the CMA has the authority to stop it from happening, or they can allow it to go ahead but insist the new firm sells certain assets which would limit its market share
    • E.g. in July 2022 the CMA launched an investigation into the merger of two companies which produce foam used in bedding & cleaning products as they believed it would lead to higher prices & less choice

Intervention to Control Monopolies

  • In addition to controlling merger activity, the CMA continuously intervenes in markets in order to promote competition & to protect the interests of consumers

Types Of Intervention In Monopoly Markets

Price regulation Profit regulation
  • Monopolies aim to produce at the profit maximisation level of output (MC=MR)
  • This results in higher prices & limited output in the market
  • The CMA uses maximum prices to lower prices & increase output
  • One way in which they determine where the maximum price should be is to identify the point of allocative efficiency & set the maximum price there
  • This strategy is often used on natural monopolies
  • Firms will make less supernormal profit than before
  • The CMA may choose to limit the supernormal profit a monopoly can earn
  • They do this by calculating the firms total costs & then adding a percentage of profit to it
  • However, it is a very contentious policy as
    • Costs are difficult for the CMA to calculate
    • Firms often try to inflate their perceived costs so as to make more profit than allowed
    • Monopolies have no incentive to lower costs, so if costs are higher than they would be in perfect competition consumers still end up paying higher prices
    • Even with this policy in place, natural monopolies seem to post record profits year on year
Quality standards Performance targets
  • One way to maximise profit is to reduce the quality of the raw materials which reduces the quality of the end good/service
  • If there are no substitutes then this is a likely outcome
  • Regulators can step in to insist that certain quality standards are met
  • It can be difficult for them to know what the potential quality of a product is or what standards to impose
  • Firms push back on these quality standards as they reduce their supernormal profit
  • Regulators can also set performance targets so as to raise the quality of the service & improve customer satisfaction
  • This is often seen in the rail industry where targets are set based on the percentage of trains running on time

Intervention to Promote Competition & Contestability

  1. Promotion of small business: providing tax incentives or subsidies to small firms can help increase the number of new entrants into industries & thus promote competition
  2. Deregulation: Goverment regulations can increase industry costs or act as a barrier to entry. Removing regulations can promote competition which will also increase the contestability in the market
  3. Competitive tendering for government contracts: as a major provider of goods/services in the economy the government could choose to manufacture many products itself & this would decrease competition. By outsourcing the supply of these products it generates more private sector activity & increases competition
  4.  Privatisation:  Firms are hesitant to enter an industry when the dominant firm is owned by the government & has access to all of the government's resources. Privatisation encourages new entrants to the industry as they feel they can compete more effectively with private firms which perhaps have less resources available to them e.g. In April 2022 the UK Government confirmed that Channel 4 would be privatised

Intervention to Protect Suppliers & Employees

Protecting Suppliers

  • Monopsony power is abusive towards suppliers & over time can change the nature of entire industries in an economy
    • Governments can pass anti monopsony laws & issue fines if breaches occur
    • They can encourage firms to self regulate & trade fairly
    • They can appoint a regulator to monitor the practices in the industry
    • They can subsidise firms that are suffering from abusive monopsony power
    • They can set minimum prices which buyers have to pay suppliers
  • Nationalisation can also be used to break the market power of the abusive firm resulting in better treatment of suppliers

Protecting Employees

  • Wage bills for firms are often one of their highest costs as a proportion of expenditure
  • With a goal of profit maximisation firms will always seek to reduce their wage expenditure as this will result in higher profit
  • There is a role for government to protect workers who could be exploited by firms
  • The government uses the following methods to protect employees
    • National minimum wage legislation
    • Legislation on health & safety, working hours & employment conditions e.g. maternity pay
    • Permitting trade unions to operate in the economy (some countries limit or ban the existence of unions as they view them as anti-competitive e.g. Singapore)
    • Encouraging firms to adopt best practice & draw up company codes of conduct towards their employees. This is a form of self regulation
