a) Significance of market power: o cartels, collusion, restrictive practices and tacit agreement o monopsony power o natural monopolies o power in the labour market
Market power causes market failure by distorting prices and output, misallocating resources. Cartels and collusion (including tacit agreements) involve firms restricting competition to act like a monopoly, raising prices and reducing consumer surplus. Restrictive practices create barriers to entry. Monopsony power occurs when a single buyer dominates, such as a large supermarket forcing down prices paid to dairy farmers. Natural monopolies exist when high fixed costs mean only one firm can fully exploit economies of scale, like a national water grid. Power in the labour market, such as trade unions or monopsony employers, distorts wage rates away from the competitive equilibrium, causing unemployment or worker exploitation.
b) The implications of market failure in the business world for economic agents and governments
Market failure occurs when the price mechanism leads to an inefficient allocation of resources, creating significant implications for economic agents (consumers, producers, workers) and governments. For consumers, market failure often means higher prices or under-provision of merit goods, reducing welfare. Producers might face distorted incentives, such as overproducing demerit goods or ignoring negative externalities like pollution, which lowers private costs but harms society. Workers may suffer from occupational immobility or monopsony exploitation. Governments are compelled to intervene to correct these inefficiencies, using taxation, subsidies, or regulation. This intervention incurs opportunity costs and risks government failure.
Your focus
- Explain how cartels, collusion, restrictive practices and tacit agreement lead to market failure and a loss of consumer welfare.

Market failure exam tips
Marking Points
- Define the specific type of market power being assessed, such as monopsony, natural monopoly, or a cartel.
- Explain how the identified market power leads to a misallocation of resources or market failure.
- Apply the concept to a real-world example, such as supermarkets exercising monopsony power over agricultural suppliers.
- Analyse the impact on stakeholders, such as reduced consumer surplus from collusion or lower wages resulting from a monopsony employer.
- Identify restrictive practices, such as predatory pricing, that create barriers to entry and sustain market power.
- Identify specific types of market failure, such as negative externalities or monopoly power, affecting the business world.
- Explain the impact of market failure on consumers, such as reduced consumer surplus or lack of access to essential services.
- Analyse how producers benefit or suffer from market failures, including the exploitation of market power or the burden of external costs.
- Evaluate the necessity and consequences of government intervention to correct market failure, including the potential for government failure.
Examiner Tips
- 💡Use a diagram to illustrate the welfare loss associated with monopoly or monopsony power to strengthen your analytical points.
- 💡When discussing labour market power, contrast the effects of a trade union pushing wages up with a monopsony employer pushing wages down.
- 💡Clearly distinguish between overt collusion (cartels) and tacit agreement, noting that overt collusion is illegal and subject to regulatory fines in most jurisdictions.
- 💡Always link the specific type of market failure to its direct impact on a named economic agent.
- 💡Use real-world business examples, such as carbon emissions in manufacturing, to illustrate negative externalities.
- 💡When evaluating government implications, consider the administrative costs and opportunity costs of implementing regulations or taxes.
Common Mistakes
- Confusing monopoly power with monopsony power. Correction: a monopoly is a single seller dominating a market, whereas a monopsony is a single buyer.
- Assuming all monopolies are natural monopolies. Correction: natural monopolies specifically arise due to continuous economies of scale and high fixed costs, not merely from having a high market share.
- Believing tacit collusion involves formal agreements. Correction: tacit collusion is unspoken and informal, often involving price leadership, unlike overt cartels which involve explicit agreements.
- Confusing market failure with a business failing or going bankrupt; correction: market failure refers to a misallocation of resources in a market, not the financial collapse of an individual firm.
- Ignoring the implications for specific economic agents; correction: explicitly analyse how consumers, producers, and workers are individually affected by the market failure.
- Assuming government intervention always solves market failure; correction: evaluate the risk of government failure, where intervention leads to a deeper misallocation of resources.
