There may have been a time when an item you would like to purchase was unavailable or its price didn’t match its value. Many of us have experienced this situation. In economics, this is called a market failure. Show
What is market failure?Market failure occurs when the price mechanism fails to allocate resources efficiently, or when the price mechanism fails to function altogether. People have different opinions and judgments in regards to when the market performs inequitably. For example, economists believe that unequal distribution of wealth is a market failure caused by the market’s inequitable performance. Moreover, the market performs inefficiently when there is a misallocation of resources which causes an imbalance of demand and supply and results in prices either being too high or too low. This overall causes overconsumption and underconsumption of certain goods. The market failure can be either:
In short, market failure is caused by an inefficient allocation of resources which prevents supply and demand curves from meeting at the equilibrium point. What are market failure examples?This section will provide a few examples of how public goods can cause a market failure. Public goodsPublic goods refer to goods or services that are provided for everyone in society without exclusions. Due to these characteristics, public goods are usually supplied by the government. Public goods must attain at least one of two characteristics: non-rival and non-excludable. Pure public goods and impure public goods have at least one of them. Pure public goodsattain both characteristics. Non-rivalry means that one person's consumption of a good doesn’t prevent another person from consuming it. Non-excludability means that no one is excluded from consuming the good; even the non-paying consumers. The non-rival goods category means that if one person consumes this good it does not prevent another person from using it: If someone listens to public radio stations it does not prohibit another person from listening to the same radio program. On the other hand, the concept of rival goods (can be private or common goods) means that if a person consumes a good another person cannot consume the same one. A good example of it is food at a restaurant: when a consumer eats it, it prevents another consumer from eating exactly the same meal. As we said, the non-excludable category of public goods means that everyone can access this good, even the non-tax-paying consumer. National defence. Both taxpayers and non-taxpayers can have access to national protection. On the other hand, excludable goods (which are private or club goods) are goods that can't be consumed by non-paying consumers. For example, only paying consumers can buy products at the retail store. Free rider problemThe most common example of market failure of public goods is called the ‘free-rider problem’ which occurs when there are too many non-paying consumers. If the public good is provided by private companies, the supply costs can become too high for the company to continue providing them. This will cause shortages in supply. An example is police protection in the neighbourhood. If only 20% of people in the neighbourhood are taxpayers who contribute towards this service, it becomes inefficient and costly to provide it due to the large number of non-paying consumers. Therefore, the police that protect the neighbourhood may decrease in numbers due to the lack of funding. Another example is a free radio station. If only a few listeners are making donations towards it, the radio station needs to find and rely on other sources of funding such as the government or it will not survive. There is too much demand but not enough supply for this good. What are the types of market failure?As we briefly mentioned before, there are two types of market failure: complete or partial. The misallocation of resources causes both types of market failure. This may result in the demand for goods and services not being equal to the supply, or prices being set inefficiently. Complete market failureIn this situation, there are no goods supplied in the market at all. This results in the ‘missing market.’ For example, if consumers would like to buy pink shoes, but there are no businesses that supply them. There is a missing market for this good, therefore this is a complete market failure. Partial market failureIn this situation, the market supplies goods. However, the quantity demanded is not equal to the supply. This results in a shortage of goods and inefficient pricing that does not reflect the true value of a good demanded. What are the causes of market failure?We must be aware that it is impossible for markets to be perfect as various factors can cause a market failure. In other words, these factors are the causes of the unequal allocation of resources in the free market. Let’s explore the main causes. Lack of public goodsPublic goods are non-excludable and non-rival. This means that consumption of those goods does not exclude non-paying consumers nor prevent others from using the same good. The public goods can be secondary education, police, parks, etc. Market failure usually occurs due to the lack of public goods caused by the ‘free-rider problem’ which means that there are too many non-paying people using public goods. Negative externalitiesNegative externalities are indirect costs to individuals and society. When someone consumes this good not only they are harming themselves but also others. A production factory may be releasing dangerous chemicals that are harmful to people's health into the air. This is what is making the cost of production of the goods so low, which means that their price will also be lower. However, this is a market failure as there will be an excessive production of goods. Moreover, the products won’t reflect their true price and additional costs to the community in terms of a polluted environment and the health risks that it has. Positive externalitiesPositive externalities are indirect benefits to individuals and society. When someone consumes this good not only they are improving themselves but also improving society. An example of this is education. It increases the likelihood of individuals achieving higher-paying jobs, paying higher taxes to the government, and committing less crime. However, consumers don’t consider these benefits, which can result in the underconsumption of the good. As a result, society doesn’t experience the full benefits. This causes market failure. The under-consumption of merit goodsMerit goods include education, health care, career advice, etc. and are associated with generating positive externalities and bringing benefits to individuals and society. However, due to the imperfect information about their benefits, merit goods are under-consumed, which causes market failure. To increase consumption of merit goods, the government provides them for free. However, they are still under-provided if we take into account all the social benefits that they can generate. Overconsumption of demerit goodsThose goods are harmful to society, such as alcohol and cigarettes. Market failure occurs due to information failure as consumers do not understand the level of harm these goods can cause. Therefore, they are overproduced and overconsumed. If someone smokes they do not realise the effect that they have on society such as passing the smell and negatively impacting second-hand smokers, as well as causing long-term health problems for themselves and for others. This is all due to overproduction and overconsumption of this demerit good. Monopoly's abuse of powerMonopoly means that there is a single or only a few producers in the market which own a vast majority of the market share. This is the opposite of perfect competition. Due to that, regardless of the product's price, the demand will stay stable. Monopolies can abuse their power by setting prices very high, which can lead to the exploitation of consumers. The market failure is caused by the uneven allocation of resources and inefficient pricing. Inequalities in the distribution of income and wealthIncome includes the flow of money going to factors of production, such as wages, interest on savings, etc. Wealth is the assets that someone or society owns, which include stocks and shares, savings in a bank account, etc. The unequal allocation of income and wealth can cause market failure. Due to technology someone receives an extremely high salary in comparison to average workers. Another example is the immobility of labour. This occurs in areas where there are high unemployment rates, resulting in inefficient use of human resources and slowing economic growth. Environmental concernsThe production of goods raises environmental concerns. For example, negative externalities such as pollution come from the production of goods. Pollution damages the environment and causes health problems to individuals. The production process that generates pollution to the environment means that the market is performing inefficiently, which causes a market failure. How do governments correct market failure?In microeconomics, the government attempts to intervene to correct the market failure. The government can use different methods to correct complete and partial market failures. The key methods that a government can use are:
Correcting complete market failureComplete market failure means that the market is non-existent and the government tries to correct this by establishing a new market. The government attempts to provide goods such as road work and national defence to society. Without the government’s efforts, there may be no or lack of providers in this market. In terms of government corrections to the complete market failure, the government tries to either replace the market or completely eliminate it. The government makes the market of demerit goods (such as drugs) illegal and replaces them by making the markets of secondary and high school education and healthcare free. An additional example is when the government attempts to abolish the production of negative externalities by issuing fines or making it illegal for businesses to produce pollution above a certain level. Correcting partial market failurePartial market failure is the situation when markets are performing inefficiently. The government attempts to correct this market failure by regulating supply and demand, and pricing. The government can set high taxes for demerit goods such as alcohol to lower their consumption levels. Moreover, to correct inefficient pricing, the government can make maximum pricing (price ceilings) and minimum pricing (price floors) laws. Government failureEven though government attempts to correct market failure, this does not always bring satisfactory results. In some cases, it can cause problems that did not exist previously. Economists call this situation a government failure. Government failure When the government's interventions bring more social costs than benefits into the market. The government may attempt to correct the market failure of over-consumption of demerit goods such as alcohol by making it illegal. This can encourage illegal and criminal actions such as selling it illegally, which brings more social costs than when it was legal. Figure 1 represents government failure in achieving pricing efficiency by setting a minimum pricing (floor pricing) policy. P2 represents a legal price for a good and anything below that includes P1 is considered illegal. However, by setting these price mechanisms, the government fails to acknowledge that it prevents equilibrium between demand and supply, which causes excess supply. Figure 5.

What is an example of a market failure?A simple example of market failure is when a monopolist seller sets high rates to the products leaving no choice for the buyers other than to purchase the overpriced goods.
Which of the following is the best example of a government effort to address market failure in respect to the for whom to produce question?Which of the following is the best example of a government effort to address market failure in relation to the FOR WHOM to produce question? Answers: Antitrust policy.
What is the role of government in market failure?One role of government is to correct problems of market failure associated with public goods, external costs and benefits, and imperfect competition. Government intervention to correct market failure always has the potential to move markets closer to efficient solutions, and thus reduce deadweight losses.
