Government intervention is when the state
Gets involved in markers and takes action to correct market failure, improve economic efficiency and change the distribution of income and wealth
What can governments use to change price signals, get better information or change resource allocation?
Regulations, taxes, subsidies, max and min prices to change price signals,
Direct provision to change resource allocation
Main reasons for government intervention
Fiscal policy can be used to alter the level
Of demand for different products and the pattern of demand.
How can indirect taxes be used to alter the level of demand
Indirect taxes can be used to raise the price of de-merit goods and products with negative externalities designed
to increase the opportunity cost of consumption and thereby reduce demand towards a socially optimal level.
How can subsidies be used to alter the level of demand
Subsidies to consumers will lower price of merit goods. They are designed to boost consumption and output
of products with positive externalities
– remember that a subsidy causes an increase in market supply and leads
to a lower equilibrium price.
How does tax relied alter the level of demand
government may offer financial assistance such as tax creditsfor business investment in research
and development. Or a reduction in corporation tax (a tax on company profits) designed to promote new capital
investment and extra employment.

Arguments against a sugar tax
Exam hint: Always worth stating that marginal social costs are
Difficult to measure - can make it hard to assign the right level of taxation to correct for externalities and overcome the market failure
Are subsidies effective in meeting their aims?
o Will they achieve the desired stimulus to demand / consumption?
o Is a subsidy sufficient? Might other incentives be needed to change behaviour e.g. some “nudges”
Will a subsidy affect productivity / efficiency?
o Subsidies for investment and research can bring positive spill overs
o But firms may become dependent on state aid / financial assistance and innovate less over time
How much does a subsidy cost and who benefits?
o Is a subsidy part self-financing? Will it create more tax revenue?
o Or does a subsidy create an expensive extra burden for taxpayers who may not have benefitted and therefore be inequitable?
What is a maximum price?
Main aim, how to set price effectively
• legally imposed maximum price in a market that suppliers cannot exceed.
- A maximum price is introduced in an attempt to prevent price from rising above a certain level.
• aim of max is equity so that goods are more widely available to the general population.
• To be effective as a form of intervention, a maximum price has to be set below the existing free market equilibrium price
If quantity is restricted,then some consumers will be willing to pay
A higher ‘unofficial’ price , so producers can extract extra consumer surplus at higher price

What is a minimum price?
price floor
It is a legally imposed price floor below which the normal market price cannot fall. To
be effective, a minimum price has to be set above the normal equilibrium price.
Many environmental economists recommend applying the polluter pays
principle and placing a price on carbon dioxide and other greenhouse gases
What is carbon emissions trading?
increasing the scarcity of carbon permits leads to an increase in
price
= more expensive to emit carbon, so capital investment into low carbon tech
