Market Failures and the Role of State Intervention

MARKET FAILURES AND THE ROLE OF THE STATE

Market failure occurs when a free market economy is insufficient in allocating resources efficiently, ensuring overall societal welfare, or meeting social needs. In other words, when market mechanisms operate solely based on supply and demand principles, the general interests of society may be ignored and resources may be distributed unevenly. In free market economies, market failures arise when the supply and demand mechanism fails to optimize societal welfare. That is, when markets are left to self-regulate, resources may not be allocated efficiently and overall societal welfare may decline. Market failures are typically situations requiring state intervention. Such interventions help balance the economy by considering the public interest when markets prove inefficient or fail to deliver social benefit.

EXTERNALITIES

Externalities are costs or benefits resulting from an economic activity that affect third parties who are not directly involved in the activity. Because externalities are not reflected in market prices, these effects are often ignored, leading to inefficient allocation of resources. Externalities typically distort economic efficiency and negatively or positively impact overall societal welfare.

Negative externality (adverse externality)

This occurs when an economic activity imposes costs on third parties or society at large who are not participating in the activity. Because those responsible for the activity do not account for these harms or internalize the costs, inefficiency arises across the society. In other words, an individual or firm shifts the negative effects of its actions onto the rest of society without paying any fee for them.

The harms caused by activities are not accounted for by market actors. For example, pollution from a factory is not treated as a cost by the operator, but nearby residents and society suffer the negative consequences. Negative externalities typically harm society or the environment, and these harms are not included in the decision-making of individuals or firms. Since markets do not consider these negative effects, resources are used inefficiently and economic losses occur.

Gases released into the atmosphere or waste discharged into water during a factory’s production process can threaten the health of local populations and contribute to the road of natural resources. However, these damages are not included in the factory’s costs and firms do not pay for these environmental impacts. The state attempts to control such externalities through environment laws and regulations. The state can implement various interventions to reduce these negative externalities. A pollution tax (carbon tax such as) can be imposed on firms that pollute the environment, requiring them to pay for the damage they cause. Factories can be required to meet specific environmental standards, such as setting emission limits or imposing legal obligations to ensure waste recycling. Commercial incentives, such as carbon credit trading, can be created to encourage polluting firms to “clean up” the extent of their pollution.

Positive externality (beneficial externality)

This occurs when an economic activity generates benefits for third parties or society at large who are not directly involved in the activity. In other words, an individual or firm does not limit the benefits of its actions to itself but allows others in the surrounding community or society to benefit as well. However, these benefits are not reflected in market prices, and those producing the activity receive no payment for the societal gains they create. Positive externalities generally produce beneficial and efficiency-enhancing outcomes for society, but they are often underproduced or insufficiently incentivized because they do not generate direct gain in the market. Therefore, state intervention may be necessary.

An activity provides benefits not just to the individual but to society as a whole. This often leads to underproduction due to demand that is not adequately met at the individual level. The benefit provided by an individual or firm extends beyond their own costs. Other individuals or society benefit from these advantages without paying. Positive externalities can lead to more efficient use of resources and increased overall societal welfare. The state implements various policies to encourage and increase positive externalities. The state can provide subsidies in areas such as education or healthcare to promote greater investment in these fields. Financial support can be offered to incentivize R&D in innovative technologies. Tax incentives can be granted to firms developing environmentally friendly technologies, encouraging more companies to adopt sustainable production methods.

INFORMATION ASYMMETRY

In an economic situation, information asymmetry occurs when two or more parties do not have equal access to information relevant to a transaction. In such cases, one party having more or better information than the other can lead to inefficient market outcomes. Information asymmetry, particularly in markets, prevents decision-makers from having adequate information about the true true value of products or services, resulting in inefficient allocation of resources and potential inefficiencies.

Information asymmetry commonly arises from disparities in information between sellers and buyers, but it can also occur in other areas such as between employees and employers or in the insurance sector. One party possesses more or higher quality information than the other, giving that party an advantage and allowing them to make decisions in their own interest. Information asymmetry can cause market inefficiencies because correct decisions cannot be made. Buyers and sellers may make erroneous decisions due to mutual information gaps. It often stems from hidden or undisclosed information. For example, a seller may withhold information about defects in a product from the buyer.

There is information asymmetry between insurance companies and insured individuals. The insured person may have more information about their health and risk status than the insurance company. This leads to a situation known as “adverse selection,” where the insurer cannot accurately assess high-risk individuals and may charge excessive premiums. Similarly, the insured person, knowing their own risk level better, may conceal their condition to pay lower premiums.

Adverse Selection: This situation occurs when high-risk individuals purchase more of a product or service than low-risk individuals, distorting the market.

Moral Hazard: A situation in which one party engages in irresponsible behavior toward another due to information asymmetry. For example, after obtaining insurance, a person may engage in more risky behavior because the insurance company bears the risk and the individual does not directly face the potential losses.

The state reduces the effects of information asymmetry by implementing regulations that ensure firms and consumers have access to accurate and sufficient information. For example, regulations such as food labeling, disclosures about insurance policies, and transparency requirements for financial products enable buyers to make more informed decisions. The state can conduct oversight and impose penalties to prevent malicious behaviors such as withholding information or misleading advertising. The state can also run public awareness campaigns to provide accurate information to consumers, workers, and firms. For instance, it can offer education in areas such as health, safety, or financial literacy. By ensuring that small enterprises or individuals have access to accurate information, the state can encourage greater competition in markets, thereby reducing the impact of information asymmetry.

PUBLIC GOODS

Public goods are those that everyone can benefit from equally and whose use by one person does not prevent others from using them. Public goods are typically underprovided in the market. This is because private sector actors, motivated by profit, find it difficult to produce goods that benefit everyone and from which no one can be excluded. Therefore, state intervention is generally required to ensure the provision of public goods.

Because the production and provision of public goods are typically unprofitable for the private sector, the state must step in. For example, clean air, security services, or infrastructure are not adequately supplied by market actors because those who benefit from these goods cannot be excluded and the costs are spread across others. Since public goods are enjoyed by everyone, it is essential that they are provided in some form for the entire society. The state ensures that public goods reach all segments of society to promote equality and justice.

One of the most significant problems with public goods is that individuals benefit from them without paying, leading to free-riding. That is, some individuals can enjoy the benefits of public goods without contributing to their provision. For example, in public goods such as road safety or clean air, some people can benefit without making any contribution. The state uses various taxation methods to solve these free-rider problems and ensure that everyone contributes to the provision of these goods.

The financing required for the provision of public goods is typically provided by the state. Through tools such as taxation, the state covers the production costs of these goods and ensures equal access for all individuals. The state monitors the sustainable provision of public goods. For example, by implementing environmental regulations and laws to protect the environment, the state prevents the misuse of public goods such as environmental protection. Public goods have two key characteristics:

Non-rivalry: When one person benefits from a public good, it does not prevent others from benefiting from it. For example, the existence of a park does not prevent one person from using it from allowing others to use it as well.

Non-excludability: It is impossible to exclude anyone from benefiting from a public good. In other words, no one can be prevented from using public goods. For example, everyone is equally affected by environmental issues such as air pollution.
