Welcome to Competition Policy!
Have you ever wondered why there isn't just one giant supermarket in the UK charging whatever prices it wants? Or why tech companies get investigated when they try to buy out their competitors? That is all down to competition policy.
In this chapter of Business Economics, we explore how governments and independent regulatory bodies step in to make sure markets work fairly for consumers, workers, and businesses. Don't worry if some of the terminology seems unfamiliar at first—we will break down every mechanism, formula, and policy step by step!
1. What is Competition Policy?
Competition policy refers to government measures, laws, and regulatory actions designed to promote competition, prevent the abuse of monopoly power, and protect consumer welfare in markets.
Core Objectives of Competition Policy
Regulators intervene in markets to achieve several key economic goals:
• Lower Prices (Allocative Efficiency): By preventing monopolies from setting artificially high prices, prices move closer to marginal cost (\(P = MC\)).
• Lower Production Costs (Productive Efficiency): Competition pressures firms to eliminate waste (reducing X-inefficiency) and produce at the lowest point on their average cost curve (\(AC\)).
• Better Quality and Choice: When businesses compete, they must offer superior customer service and a wider range of products to win sales.
• Innovation and Progress (Dynamic Efficiency): Firms are incentivised to invest in research and development (\(R\&D\)) to stay ahead of rivals.
• Fairness and Consumer Protection: Stopping large, powerful corporations from exploiting vulnerable consumers.
Everyday Analogy: Think of a competition regulator like a referee in a sports match. The referee does not play the game or choose the winner; instead, they enforce the rules so that no single player cheats or bullies the others off the pitch.
Quick Review: The ultimate aim of competition policy is to make markets operate more efficiently so that consumers enjoy lower prices, higher quality, and greater choice.
2. Who Enforces Competition Policy?
In the UK and Europe, competition policy is overseen by specialised bodies:
1. The Competition and Markets Authority (CMA):
The main independent competition watchdog in the UK. The CMA investigates proposed mergers, looks into entire market sectors (like retail banking or energy), and prosecutes illegal anti-competitive behaviour.
2. Sector-Specific Regulators (Utility Regulators):
Certain key industries have natural monopoly characteristics and require dedicated regulators:
• Ofgem: Regulates gas and electricity markets.
• Ofwat: Regulates the water and sewerage industry.
• Ofcom: Regulates telecommunications, broadband, and postal services.
• ORR (Office of Rail and Road): Regulates railways and major road networks.
3. The European Commission:
Oversees competition across the European Union single market, dealing with cross-border anti-competitive behaviour and mega-mergers affecting member states.
3. The Three Pillars of Competition Policy
To keep markets fair and contestable, competition authorities focus on three main areas:
Pillar 1: Merger and Takeover Control
A merger occurs when two or more independent firms agree to join together. While mergers can create economies of scale that lower costs, they also increase market concentration.
The CMA investigates mergers under specific criteria, such as:
• The merged business will have a market share of \(25\%\) or more in the UK (the share of supply test), or
• The UK turnover of the enterprise being acquired exceeds a specified financial threshold (typically \(\text{£}70\text{ million}\)).
The CMA tests whether the merger will result in a Substantial Lessening of Competition (SLC). If a merger will significantly reduce competition, the regulator can:
1. Approve the merger unconditionally.
2. Permit with remedies (e.g., requiring the merged firm to sell off specific stores, factories, or flight slots to rivals).
3. Block the merger entirely.
Example: The CMA blocked the proposed merger between UK supermarket giants Sainsbury's and Asda because it found the deal would lead to increased prices and reduced choice for UK shoppers at both the national and local level.
Pillar 2: Preventing Collusion and Anti-Competitive Agreements (Cartels)
A cartel is a formal agreement between rival firms to limit competition. Under UK and EU law, cartels and restrictive agreements are strictly illegal.
Practices targeted by the CMA include:
• Price Fixing: Competitors secretly agreeing to set the same high price instead of undercutting one another.
• Market Sharing: Firms agreeing to divide geographic territories or customer groups to avoid competing.
• Bid Rigging (Collusive Tendering): Firms taking turns to submit artificially high bids for public contracts so that a designated firm wins the tender at an inflated price.
How Cartels are Broken: Authorities use severe financial penalties (up to \(10\%\) of global turnover), criminal sanctions (prison sentences for executives), and leniency programmes. Under a leniency programme, the first member of a cartel to "blow the whistle" and provide evidence is granted total immunity from fines.
Pillar 3: Preventing the Abuse of a Dominant Position
Holding a large market share is not illegal by itself. However, using that power to harm rivals or exploit consumers is an abuse of monopoly power.
Abusive practices include:
• Predatory Pricing: Setting prices deliberately below average variable cost (\(P < AVC\)) in the short run to force smaller competitors out of business, followed by raising prices once the rival is eliminated.
• Limit Pricing: Setting prices just low enough to make it unprofitable for new entrants to enter the market.
• Tying and Bundling: Requiring consumers to buy one product in order to get access to another unrelated product.
• Refusal to Supply: Denying essential components or network infrastructure to competitors without a valid commercial reason.
Key Takeaway: Regulators do not punish firms for being large and successful; they punish firms that use their size to break rules, fix prices, or shut out competition.
4. Regulating Privatised Utilities and Natural Monopolies
A natural monopoly occurs when high fixed capital costs and massive economies of scale make it most efficient for a single firm to supply the entire market (e.g., national water pipe networks, railway tracks, or electricity grids). Having multiple firms lay duplicate water pipes under the street would be wasteful and inefficient.
Because these firms face no direct competition, regulators must step in to control prices and quality.
1. Price Capping: \(RPI - X\) and \(RPI - X + K\)
Price capping sets a strict limit on the maximum percentage increase in price a regulated utility can charge its customers over a set period (typically \(5\text{ years}\)).
The Formula: \(RPI - X\)
• \(RPI\) = Retail Price Index (a measure of inflation).
• \(X\) = The efficiency gain that the regulator expects the firm to achieve.
How it works in practice:
Suppose inflation (\(RPI\)) is \(4\%\) and the regulator sets \(X = 1.5\%\).
The maximum price increase the firm can implement is:
\(\text{Maximum Price Increase} = RPI - X = 4\% - 1.5\% = 2.5\%\)
Because prices rise by less than inflation, the real price of the service falls for consumers!
The Incentive Effect: If the firm cuts its production costs by more than \(X\) (for example, achieving a \(3\%\) efficiency saving), it gets to keep the extra cost savings as higher profit until the next regulatory review. This strongly encourages productive efficiency.
The Water Formula: \(RPI - X + K\)
In industries requiring huge long-term infrastructure investment (like upgrading clean water pipelines), regulators add a capital expenditure factor, \(K\):
\(\text{Max Price Change} = RPI - X + K\)
Here, \(K\) represents the allowed extra price increase to fund essential capital investment.
2. Rate of Return (Profit) Regulation
Instead of capping prices, rate of return regulation places a legal limit on the percentage return on capital employed that a utility can earn.
• Advantage: Ensures the firm covers its costs and earns a fair, predictable profit to fund repairs and upgrades.
• Disadvantage: Leads to the Averch-Johnson effect (also called "gold-plating"). If profits are allowed to be a set percentage of capital, the firm is incentivised to over-invest in unnecessary, expensive machinery and capital equipment just to boost total allowed profit in cash terms.
3. Quality Standards and Performance Targets
Under price caps, firms might try to cut costs by lowering service standards. To prevent this, regulators set strict performance benchmarks, such as:
• Maximum allowable minutes of power cuts for electricity firms.
• Limits on sewage spills and water leaks for water companies.
• Targets for train punctuality.
Firms that fail to meet these targets face substantial financial fines.
4. Promoting Contestability and Deregulation
Regulators can break up monopolistic structures by splitting network ownership from service delivery:
• In broadband, Openreach maintains the physical cables, but is legally required to allow rival Internet Service Providers (Sky, TalkTalk, Vodafone) to use the lines on equal terms.
• In rail, Network Rail owns the tracks, while private Train Operating Companies compete to run rail services.
5. Evaluating Competition Policy: Challenges and Limitations
Competition policy does not always work perfectly. When evaluating government intervention in an exam, consider the following limitations:
1. Asymmetric Information:
Regulated firms know far more about their actual operating costs, future technologies, and profit margins than the regulator does. Firms may exaggerate their costs to convince the regulator to set a lenient price cap (\(X\) set too low).
2. Regulatory Capture:
Over time, regulatory officials may develop close personal and professional ties with the executives of the firms they oversee. The regulator may become overly sympathetic to the industry's interests at the expense of consumers.
3. Impact on Dynamic Efficiency:
Tough price caps and heavy fines lower supernormal profits. If a firm's profits are squeezed too tightly, it may lack the retained profit needed to fund long-term capital investments, research, and green technologies.
4. Unintended Consequences:
Strict price caps can lead to corner-cutting, reduced maintenance budgets, and lower quality of service as firms scramble to meet cost targets.
5. High Costs of Regulation:
Gathering data, conducting complex market investigations, and fighting legal battles in court require significant taxpayer resources and take years to conclude.
Common Mistakes to Avoid
• Mistake 1: Believing that having a monopoly or high market share is illegal in the UK.
Correction: Having a large market share is completely legal; it is only the abuse of that dominant market position (such as predatory pricing or anti-competitive mergers) that is illegal.
• Mistake 2: Confusing \(RPI - X\) with \(RPI + X\).
Correction: The minus sign is vital! \(X\) represents efficiency savings that reduce the allowed price increase relative to inflation.
• Mistake 3: Assuming all mergers are bad for consumers.
Correction: Mergers can generate significant economies of scale, reduce duplication, and provide funds for dynamic investment, which can lead to lower prices and better products for consumers.
