Government Intervention to Control Mergers

The primary goal of controlling mergers is to prevent the creation or strengthening of market power that would lead to a substantial lessening of competition (SLC) and ultimately harm consumer welfare (e.g., through higher prices or reduced quality/choice).

• Regulator: In the UK, the Competition and Markets Authority (CMA) is responsible for investigating mergers.

• Threshold: The CMA typically investigates mergers where the combined firm would have a market share of 25% or more (or if the firm's turnover exceeds a certain threshold).

• Assessment: The CMA conducts two phases of investigation:

  1. Phase 1: Initial assessment for an SLC. If concerns exist, it moves to Phase 2.

  2. Phase 2: Detailed investigation, gathering evidence, and economic modelling.

• Outcomes: The CMA can:

  • Approve the merger (full clearance).

  • Block the merger entirely.

  • Approve with remedies (conditions), such as requiring the merged firm to divest (sell off) a part of its business to limit its market share or agreeing to specific behavioral commitments (e.g., price caps).

Government Intervention to Control Monopolies

Price Regulation

Setting a maximum price (price cap) on a monopolist's output, often near the allocatively efficient point (P = MC) or average cost (P = AC).

Profit Regulation

Limiting the amount of supernormal profit a monopoly can earn, often based on a Rate of Return on Capital Employed.

Quality Standards

Imposing minimum requirements for product or service quality.

Performance Targets

Setting measurable goals for aspects like speed, reliability, or customer service.

Government Intervention to Promote Competition and Contestability

These policies are primarily supply-side policies aimed at increasing the number of actual and potential competitors in a market.

• Enhancing competition between firms through promotion of small business:

  • Providing subsidies, grants, or tax incentives to Small and Medium-sized Enterprises (SMEs).

  • Reducing the burden of 'red tape' (excessive regulation) to lower barriers to entry for smaller firms.

  • Improving access to finance for start-ups.

• Deregulation:

  • Removing or simplifying legal restrictions and unnecessary rules that act as barriers to entry.

  • This increases contestability, as new firms can enter the market more easily, forcing incumbents to behave competitively. Example: Deregulation of the bus and airline industries.

• Competitive Tendering for Government Contracts:

  • Instead of a government department or a state-owned enterprise providing a service, private firms bid competitively to win the contract.

  • This introduces competition for the market (not in the market), driving down costs and improving efficiency for public services. Example: Outsourcing of waste collection or management of prisons.

• Privatization:

  • The transfer of assets and enterprises from the public sector to the private sector.

  • Rationale: Private firms are driven by the profit motive, leading to incentives for productive efficiency, cost-cutting, and greater innovation. Often accompanied by deregulation to introduce competition.

Government Intervention to Protect Suppliers and Employees

These interventions are designed to counter the exploitation that arises from excessive market power, particularly monopsony power (a single dominant buyer).

• Restrictions on Monopsony Power of Firms:

  • Monopsony power allows a dominant buyer to force down the price paid to suppliers or the wage paid to employees.

  • Legislation/Regulation: The CMA can investigate and place restrictions or fines on firms abusing their buying power.

  • Fair Trading Laws/Codes of Practice: Establishing minimum standards for contracts and payment terms to protect small suppliers (e.g., from late payments by large supermarkets).

  • Minimum Wage Legislation: Directly prevents the exploitation of workers by setting a wage floor above the monopsony wage, protecting employees in monopsonistic labour markets (e.g., the NHS as the main employer of nurses).

• Nationalization:

  • The transfer of ownership of a private sector firm or industry to the state/public sector.

  • Rationale: Can be used to break up private sector monopolies or control key strategic industries (like utilities or railways). Under state ownership, the firm's objective can be shifted from profit maximization to social welfare maximization (P = MC or maintaining essential services).

  • However: Publicly owned firms may suffer from bureaucratic inefficiencies and lack the strong incentive to cut costs provided by the profit motive.
