⚖️ Competition Policy
Definition: Competition policy.
Key tools of competition policy
- Anti-monopoly legislation — laws that prevent firms from abusing a dominant position (e.g. EU competition law, US Sherman Act).
- Merger regulation — government reviews and can block mergers that would significantly reduce competition.
- Breaking up monopolies — in extreme cases, the government can force a monopoly to split into smaller firms.
- Fines for anti-competitive behaviour — price-fixing, market-sharing, and predatory pricing can be punished with large fines.
Real-world example: In 2024, the EU fined Apple €1.84 billion for abusing its dominant position in music streaming by preventing Spotify and others from telling users about cheaper alternatives outside the App Store.
🏭 Regulation and Natural Monopoly
Definition: A natural monopoly.
Examples of natural monopolies
Water supply, electricity grids, railway networks, gas pipelines. These all require massive infrastructure where duplication would be wasteful.
The dilemma
- Breaking up a natural monopoly would raise costs (you'd have duplicate networks).
- But leaving it unregulated lets the firm charge monopoly prices and earn supernormal profits.
- Solution: regulate the monopoly rather than break it up.
Regulation methods
- Price regulation — government sets a maximum price (often at P = AC so the firm earns normal profit only).
- Rate-of-return regulation — sets a cap on the allowed rate of profit.
- Quality standards — ensures the firm doesn't cut quality to boost profits.
- Nationalisation — the state owns and operates the monopoly directly.

🔎 Evaluation of Policy Responses
- ✅ Competition policy can lower prices, increase choice, and improve efficiency.
- ✅ Merger regulation prevents harmful consolidation before it happens.
- ✅ Regulation of natural monopolies keeps prices fair without losing economies of scale.
- ❌ Competition authorities may lack information — hard to distinguish competitive behaviour from anti-competitive.
- ❌ Regulation is costly and firms may 'game' the rules (regulatory capture).
- ❌ Breaking up firms can reduce economies of scale and innovation incentives.
- ❌ Nationalisation may lead to productive inefficiency (no profit motive → less cost control).
For top marks, acknowledge that some market power can be beneficial: it funds R&D (Schumpeter's argument), rewards innovation, and achieves economies of scale. The goal isn't to eliminate market power entirely, but to prevent its abuse.
