Market Failure

Definition

Market failure occurs when the allocation of goods and services by a free market is not efficient, leading to a net loss of economic value. This inefficiency can arise from various factors, such as externalities, public goods, and information asymmetries. Market failures highlight situations where individual incentives do not lead to socially optimal outcomes, often prompting the need for intervention to correct these inefficiencies.

5 Must Know Facts For Your Next Test

1. Market failure can result in overproduction or underproduction of goods, creating inefficiencies that harm economic welfare.
2. Governments often intervene in cases of market failure to promote social welfare through regulations, taxes, or subsidies.
3. Externalities, such as pollution, can create significant market failures by imposing costs on society that are not reflected in the market price.
4. In the presence of public goods, market failure occurs because private firms may lack the incentive to provide these goods due to their non-excludable nature.
5. Market failures can also lead to inequality, as some individuals may be left without access to necessary resources or services due to their inability to pay.

Review Questions

• How do externalities contribute to market failure and what are some examples of positive and negative externalities?
  • Externalities play a crucial role in market failure by creating situations where the true costs or benefits of an economic activity are not reflected in the market prices. For instance, pollution from a factory represents a negative externality because it imposes health and environmental costs on society that are not borne by the factory itself. Conversely, a well-maintained garden can be seen as a positive externality, as it enhances neighborhood property values without requiring compensation from neighbors.
• Analyze how public goods can lead to market failure and what mechanisms can be employed by governments to address this issue.
  • Public goods lead to market failure due to their non-excludable and non-rivalrous nature, which means private markets may underprovide these goods. Since individuals cannot be excluded from using public goods like national defense or street lighting, there’s little incentive for private firms to supply them. Governments can address this issue through taxation and provision of public goods directly, ensuring that essential services are available for all members of society.
• Evaluate the implications of information asymmetry on market efficiency and how government intervention can help mitigate its effects.
  • Information asymmetry creates inefficiencies in markets as it prevents equitable transactions; one party with more information may exploit their advantage, leading to adverse selection or moral hazard. For example, in the used car market, sellers might have more knowledge about a vehicle's condition than buyers, resulting in less desirable cars dominating the market (the 'lemons problem'). Government intervention can help mitigate these effects through regulations that require transparency and disclosure of information, helping ensure that all parties can make informed decisions.

Related terms

Externalities:

Externalities are costs or benefits incurred by third parties who are not directly involved in a transaction, leading to market inefficiencies.

Public Goods:

Public goods are commodities that are non-excludable and non-rivalrous, meaning that individuals cannot be effectively excluded from use and one person's use does not reduce availability to others.

Information Asymmetry: Information asymmetry occurs when one party in a transaction has more or better information than the other, leading to potential market distortions.
