Market failure usually happens when there is an inefficient allocation of resources in a free market. This can happen due to numerous reasons like when there is a monopoly that drives up prices, or negative externalities over-consumed and costs to third parties.
So what happens when the system doesn’t allocate resources efficiently? This leads to a situation where goods and services are not distributed in a way that maximises overall social welfare.
In simpler terms, market failure means that the market is not working as it should, resulting in resources being wasted or used inappropriately. Understanding market failure is crucial for grasping why governments intervene in the economy to correct these inefficiencies and to ensure a fair distribution of resources and even the survival of important industries and companies.
The Meaning of Market Failure and Misallocation of Resources
Market failure can be defined as a situation where the free market, left to its own devices, fails to allocate resources in a way that optimises social welfare.
This misallocation of resources means that some goods and services are overproduced while others are underproduced. When the market fails, it leads to a poor allocation of resources, where not all needs and wants are satisfied in the most effective way.
Several factors can cause market failure. Public goods, for example, are goods that are termed non-excludable and non-rivalrous. This means that once they are provided, it is difficult or impossible to prevent anyone from using them, and one person's use does not reduce the amount available for others.
Classic examples include national defence and public parks. The market often fails to provide these goods adequately because businesses cannot easily charge individuals for their use, leading to underproduction.
“Externalities” are another significant cause of market failure.
Externalities occur when the actions of individuals or firms have an impact on third parties that is not reflected in market prices. Pollution is a typical example of a negative externality, where the social costs of production are not paid for by the producer but by society as a whole. This leads to overproduction of harmful goods.
Positive externalities, like education, create benefits for society that are not fully captured by the individual or firm, resulting in underproduction.
Positive externalities are create benefits for society that are not fully captured by the individual or firm, resulting in underproduction.
Negative externalities are those where the social costs of production are not paid for by the producer but by society as a whole
A concept called “information asymmetry” also leads to market failure. This happens when one party in a transaction has more or better information than the other. For instance, a used car seller usually knows more about the car's condition than the buyer, which can lead to adverse selection and moral hazard, where the buyer might end up paying more than the fair value or might avoid the market altogether. This is a simplistic example, but can also apply to huge mergers and deals and impact our economy.
Monopoly power can cause market failure as well. When a single firm dominates a market, it can set higher prices and produce less than what would be produced in a competitive market. This leads to inefficiency and harms consumers, who have to pay more for less as people pay more for the goods. Have you ever wondered why the prices are so high for food and drink in the cinema? A similar effect causes this, as there is no competition to drive the prices down.
The Effects of Misallocation of Resources and Market Failure
Market failure has several implications for the economy. Firstly, it often leads to an economic downturn. Resources are not used in the best possible way, resulting in wasted resources and reduced overall welfare.
For example, if too many resources are devoted to producing potentially harmful goods like alcohol, society may suffer from higher healthcare costs and reduced productivity.
Market failure often leads to social costs that are not accounted for by the market. Pollution from factories imposes health and environmental costs on society that are not borne by the producers. The asbestos industry is an example of a heavy cost to society, as people did not realise how harmful it was. Remember that cost doesn’t necessarily mean a direct financial cost.
Also, market failure can result in an inequitable distribution of wealth. For instance, monopolies can charge higher prices, benefiting the monopolists at the expense of consumers. This can lead to significant income inequality, where wealth is concentrated in the hands of a few, leaving many without access to essential goods and services. With monopolies and other issues relating to market failure, prices may not reflect the true costs and benefits of goods and services.
Government Intervention
Governments often intervene in the market to correct these failures and improve resource allocation.
One common method of intervention is through regulation and legislation. Governments can introduce laws and regulations to correct market failures. For example, environmental regulations can limit pollution, reducing the negative externalities caused by industrial activities.
Taxes and subsidies are another way governments can intervene. Taxes can be used to discourage activities that create negative externalities. For instance, a carbon tax can reduce pollution by making it more costly to emit carbon dioxide. On the other hand, governments may subsidise and reward energy production that is eco-friendly.
To address inequities, governments can implement policies that redistribute income. Progressive taxation, where higher-income individuals pay a larger percentage of their income in taxes can help reduce the gap between rich and poor, promoting social equity and stability. The UK has a progressive taxation system.
Market regulation is another essential tool for government intervention. Regulatory bodies, like the Competition and Markets Authority (CMA) in the UK, oversee and regulate markets to ensure fair competition and prevent monopolistic practices.
Providing information is also crucial in providing all parties with the right information. Governments can mandate disclosure and provide information to ensure that consumers and businesses make informed decisions. Food labelling requirements, for example, ensure that consumers know what they are buying, reducing the risk of adverse selection and moral hazard.
Revision Questions
What are some examples of the societal costs of market failure?
Market failure occurs when the allocation of goods and services by a free market is not efficient. Some examples of the societal costs of market failure include:
- Environmental Degradation: Negative externalities such as pollution from factories can harm public health and the environment, leading to long-term societal costs like climate change and loss of biodiversity.
- Public Health Issues: If healthcare is not adequately provided by the market, some individuals may not receive the necessary medical attention, leading to widespread health problems.
- Inequality: Market failure can result in unequal distribution of wealth and resources, exacerbating poverty and social tensions.
- Under-provision of Public Goods: Goods like national defence, street lighting, and public parks might be under-provided because they are non-excludable and non-rivalrous
- Monopoly Power: When firms have too much market power, they can exploit consumers by charging higher prices and limiting output.
How can governments tackle the issues caused by market failure?
Governments can use various policies and interventions to address market failure, including:
- Regulation: Setting laws and regulations to control activities that cause negative externalities, such as pollution controls or safety standards.
- Taxation and Subsidies: Imposing taxes on negative externalities (e.g., carbon tax) to discourage harmful activities and providing subsidies for positive externalities (e.g., renewable energy) to encourage beneficial activities.
- Provision of Public Goods: Directly providing public goods and services that the market fails to supply adequately, such as national defense, public transportation, and education.
Why do monopolies lead to increased prices for consumers?
Monopolies can lead to increased prices for consumers due to several reasons:
- Lack of Competition: In a monopoly, the single firm faces no competition, giving it the power to set prices higher than in competitive markets.
- Price Maker: A monopolist can determine the market price because it controls the entire supply of the product or service, unlike firms in competitive markets that are price takers.
- Barriers to Entry: High barriers to entry prevent other firms from entering the market and challenging the monopolist, allowing the monopoly to maintain higher prices without the threat of competition.
- Profit Maximisation: Monopolies aim to maximize profits by reducing output to increase prices, whereas competitive markets typically produce more at lower prices.
