1.4 - Government Intervention Flashcards
What is indirect taxation?
When the good has a negative externality,
the government can introduce indirect taxation to prevent market failure. This will cause a fall in supply and increase the costs to the individual, so the supply curve/MPC curve will shift from S1 to S2. The free market would produce at P1Q1, where MPC=MPB but the social optimum position is P2Q2, where MSB=MSC. Following the introduction of the tax, the equilibrium position is S2=MPB=MSB, at P2Q2. The tax internalises the externality and social welfare is now maximised. This diagram shows a specific tax but an ad valorem tax could also be introduced, which would have the same effect, but the shift of the curve would look slightly different.
What are the advantages of using indirect taxation?
*It internalises the externality - the market now produces at the social equilibrium position and social welfare is maximised.
*It raises government revenue, which could be used to solve the externality in other ways such as through education. This may help goods to become more elastic in the long run. The effect will depend on what the government does with the revenue they raise.
What are the disadvantages of using indirect taxation?
- It is difficult to know the size of the externality and so it is difficult to target the tax; the effect depends on where the tax is set. The government suffers from imperfect information when setting the tax
*There could be conflict between the government goal of raising revenue and solving the externality, which makes setting the tax difficult
*It could lead to the creation of a black market
*If demand for the good is inelastic, then the tax will be ineffective at reducing output
*Taxes are politically unpopular and so governments may be reluctant to introduce them - They are regressive, meaning that the poor spend a larger proportion of their income on indirect taxes than the rich do
What is ad valorem tax?
Ad valorem tax is a type of tax based on the value of an item, property, or transaction. The amount of the tax is usually calculated as a percentage of the value of the asset being taxed
What is specific (unit) tax?
It is a type of tax that is levied as a fixed amount per unit of a good or service, rather than a percentage of its value - it is regardless of how much the item costs
What are subsidies?
Subsidies are introduced by the government to solve positive externalities and/or to fix information gaps. This will shift the supply curve to the right as it will lower the cost of production. The free market would produce where MPC=MPB at Q1P1 whilst the social optimum position is where MSC=MSB at P2Q2. The introduction of the subsidy means that the equilibrium point is Q2P3, at the social optimum output. This means that social welfare is maximised since the market produces at the output that best allocates resources.
What are the advantages of using subsidies?
- Society reaches the social optimum output and welfare is maximised
- They can have other positive impacts, such as encouraging small businesses, bringing about equality, and encouraging exports
What are the disadvantages of using subsidies?
- The government has to spend a large amount of money, which will have a high opportunity cost
- As with taxes, they are difficult to target since the exact size of the externality is unknown
*Subsidies can cause producers to become inefficient, especially if they are in place for a long time
*Once introduced, subsidies are difficult to remove
What are maximum prices?
A maximum price is a legally imposed price for a good that the suppliers cannot charge above. They are set on goods with positive externalities e.g. food, rent, etc. These will only have an effect if it is set below the current price equilibrium
What are minimum prices?
A minimum price is a legally imposed price at which the price of the good cannot go below. They can be set on goods with negative externalities, so that the price is raised to the social optimum point and consumption can be discouraged. These will only have an effect if it is set above the current price equilibrium
What are the advantages of maximum and minimum prices?
- They can be set where MSB=MSC, so allow for some consideration of externalities, and so help to increase social welfare
- A maximum price will ensure that goods are affordable, whilst a minimum price will ensure that producers get a fair price. Both of these are able to reduce poverty and can increase equity/equality
What are the disadvantages of maximum and minimum prices?
- There is a distortion of price signals and this causes excess supply/demand. Excess demand will lead to questions about how to allocate goods and excess supply will lead to questions about what to do with the surplus goods
*It is difficult for the government to know where to set the prices, because of the difficulty of knowing the size of externalities and because it will have implications on the size of excess supply/demand
*Both can lead to the creation of black markets. Maximum prices may also lead to illegal bribes or discriminatory policies in allocating goods
What are tradable pollution permits?
A pollution permit allows the owner to pollute up to a specific amount of pollution and the government controls how many permits there are so limits the maximum amount of pollution. Companies have to buy permits in order to pollute so, in an attempt to cut costs and increase profits, companies may use greener technology. Unused permits can be sold to other companies, which is why they are tradable. Companies exceeding their limit of pollution will face legal action. As a fixed supply of permits is allocated, an increase in demand will lead to an increase in price for the permits, so companies will have more incentive to cut emissions by using green technology
What are the advantages of tradable pollution permits?
- Since the government caps the number of permits, it is guaranteed that pollution will fall to the targets set by the government. This will maximise social welfare
- The government can raise revenue by selling permits and by fining firms who exceed their pollution limit
*This encourages companies to use and invest in green technology - Firms are able to make their own decisions about whether to cut pollution or buy more permits. This helps encourage efficiency
What are the disadvantages of tradable pollution permits?
- This can be expensive to monitor and police, but it will only work if it is monitored well. The government needs to impose fines that are large enough to ensure firms follow the regulation
- It will raise costs for businesses, and it is likely that these higher costs will be passed onto consumers
- It may be difficult to know how many permits the government should allow
What is state provision of public goods?
Public goods are non-excludable and non-rivalry and so the free rider problem says they will be under-provided by the free market, leading to market failure. As a result, the government provides these public goods directly through taxation. Similarly, the government can provide merit goods
What are the advantages of state provision of public goods?
- This corrects market failure by providing important goods which would otherwise not be provided. It will lead to improved social welfare
*It can help to bring about equality, by ensuring everyone has access to basic goods
*There will be benefits of the goods themselves, for example by providing healthcare, the government ensures that the workforce is healthy and so this can improve economic growth
*By using competitive tenders, the government can ensure efficiency
What are the disadvantages of state provision of public goods?
- This is expensive and represents a high opportunity cost for the government. Administration costs are a problem
- Since the market is not involved, the government may produce the wrong combination of goods as consumers can not indicate their preferences. For example, there may be too many soldiers and too few hospital beds: if they were provided by the market, price signals would lead to a shift in resources. Democracy aims to reduce this problem, since consumers can vote for political parties whose aims are similar to their own
- The government may be inefficient at production since they have no incentive to cut costs
- Government officials may suffer from corruption and conflicting objectives
What is the provision of information?
When there is asymmetric information, the government provides information to allow people to make informed decisions. They may also force companies to provide information
What are the advantages of the provision of information?
- This helps consumers to act rationally, which allows the market to work properly
*It is best if the government uses this alongside other policies. For example, it can make demand more elastic in the long run and so help indirect taxes to become more effective at reducing output
What are the disadvantages of the provision of information?
*This can be expensive for the government to do, incurring an opportunity cost
* The government themselves may not always have all the information, so it may be difficult to inform consumers
* Consumers may not listen to the information provided due to irrational behaviour
What is regulation?
Governments are able to impose laws and caps to ensure that levels are set where MSB=MSC or to ensure that companies provide full information on products. The government can also introduce regulatory bodies such as OFCOM for communications and OFGEN for energy. These ensure firms follow regulation and do not exploit their customers or take advantage of market position
What are the advantages of regulation?
*This can ensure consideration of externalities, prevent exploitation of consumers, and keep consumers fully informed. This will help to overcome market failure and maximise social welfare
What are the disadvantages of regulation?
*Laws may be expensive for the government to monitor, incurring an opportunity cost
* They don’t take into account the different costs of following the laws for different companies. Compared with tradable pollution permits, regulation is a less efficient method of reducing pollution
*The government can suffer from regulatory capture
* Firms may pass on costs to the consumer in the form of higher prices
* Excessive regulation may reduce competition in a market and efficiency, by increasing bureaucracy and reducing innovation
What is government failure?
Government failure is when government intervention in the market leads to a net welfare loss and a misallocation of resources. The total social costs arising from the intervention are greater than the social benefit. There are a number of causes of government failure
What are the causes of government failure?
- Distortion of price signals
*Unintended consequences
*Excessive administrative costs - Information gaps
How does the distortion of price signals cause government failure?
*Some intervention changes price signals and distorts the free market mechanism - so they keep some companies in business when they are inefficient so their resources (subsidies) should be switched to somewhere else or they are making consumers pay too much for a good (taxes)
* e.g. subsidies keep farmers in employment when they cannot produce cheaply enough to be competitive. The result is that the government keeps them in business when they should close down and find an alternative use for their resources
*Maximum and minimum prices lead to excess demand/supply and make it difficult to allocate resources
*The price mechanism aims to allocate resources to their best use and where consumers want and value them most highly. By intervening, the government distorts the mechanism and so resources may be allocated inefficiently
How do unintended consequences cause government failure?
- Some interventions cause effects which the government did not intend to happen. Consumers and producers may react to new policies in unexpected ways and so the policy doesn’t have the effect it should
How do excessive administration costs cause government failure?
- In many cases, a lot of money that is allocated by the government is actually used up on basic administration costs. The social costs may be higher than social benefits, once administration costs are taken into account
How do information gaps cause government failure?
- Any decisions that the government makes must be based on some data but the information they have is always going to be limited, for example, you cannot accurately predict the number of cancer patients or the number of cars on the road
- Cost and benefit forecasts of investment are often wrong and so the government invests in a system where the costs are higher than the benefits, so there is welfare loss. It is impractical, and usually impossible, for the government to get every piece of information they need
