Why do the government intervene in a market?
To correct market failure, To improve performance in the economy, to achieve a more equal distribution of income and wealth
1 of 72
What can the government do about demerit goods?
Ban, limit production, minimum price, subsidise alternative, limit age, scheme to support producers, warnings/information, laissez faire
2 of 72
Define Unit/specific tax and relate it to elastitcity
This is the same moneytary tax regardless of the price, the more inelastic the demand curve the easier it is for producers to pass the tax on to consumers
3 of 72
What are the reasons for taxing?
Restrict consumption of demerit goods, control negative externalities, Deter monopoly abuse, force people to consume merit goods, promote positive externalities
4 of 72
Define Ad velorem tax
This is the same percentage of a price so a higher price means more tax e.g. VAT
5 of 72
Define Subsidy and relate it to elasticity
A subsidy is given by the government to encourage the production of a good and lower its price and increase its demand, the more inelastic the demand curve the more the producer recieves
6 of 72
Explain a minimum price
This is a price at which the market price can't fall below, It must be set above the equilibrium and causes excess supply leading to secondary markets
7 of 72
Explain a maximum price
It is set by the government or an industry to prevent the market rising above a certain level its set below the equilibrium price and causes excess demand
8 of 72
Explain pollution permits
These are rights to buy and sell potential pollution a company either go's green and sells their permits for profit or has to buy extra permits
9 of 72
Define Moral Hazard
The tendency of individuals and firms once insured against some contingency to behave so as to make it more likely
10 of 72
Define Adverse selection
A situation in which people who buy insurance often have a better idea of the risks they face than the insurance companies
11 of 72
Define public private partnership
Partnerships between the private and public sectors to provide the public service
12 of 72
Define privatisation
The transfer of a firm from the government to the public sector
13 of 72
Define private finance initiatives
A form of public and private partnership where private sector firms do the bulk of the work. The main advantage is improvements can be made without increasing government borrowing
14 of 72
Define Nationalised industries
Industries that are covered by the state. They normally have the interests of consumers at heart as they don't have to make profits
15 of 72
What are the advantages of privatisation?
promotes competition, improves efficiency and reduces X inefficiency, improves resource allocation
16 of 72
What are the disadvantages of privatsation?
Closure of loss making firms, privately run firms can ignore more negative externalities, can worsen allocation of scarce resources and are less efficient
17 of 72
Explain regulation
These are rules set by the government, they are difficult to set and expensive to enforce
18 of 72
How are regulations used to reduce market failure?
Reducing the use of demerit goods, providing protection for consumers, reducing monopoly power
19 of 72
Define deregulation
Reducing regulation removes some barriers to entry and so increases competition, its used alongside privatisation
20 of 72
What are the advantages of deregulation?
Improves efficiency, improves resource allocation so markets are more contestable
21 of 72
What are the disadvantages of deregulation?
It is difficult to deregulate some natural monopolies, it can't fix other market failures like negative externalities, can mean less safety and protection for consumers
22 of 72
What is the competition commision
A government organisation responsible for implementing policy in relation to monopoly. It investigates monopolies and situations that can lead to a monopoly.
23 of 72
What can the competition commission or the office of fair trading do if the behaviour of a dominant firm is against public interest?
order firms to stop certain trading practices, enforce price controls, tax excess profits, nationalisation, privatisation, deregulation
24 of 72
Define restrictive trading practices
These are methods used by firms to reduce competition in a market individuals use them to reinforce their dominance.
25 of 72
What are examples of restrictive trading practices?
Price discrimination, resale price maintenance ( where manufacturers fix the price retailers sell at), refusal to supply certain outlets or markets, full line forcing (where a supplier makes a firm sell more than one of its products)
26 of 72
Explain equality
It is a positive statement and occurs when people are equal and can be achieved by things like reducing wage differentials, increasing the amount of money you need before you're taxed increases equality
27 of 72
Define equity
It is a normative statement and means fairness of justice
28 of 72
Define vertical equity
Means people with higher incomes should pay more which can lead to the redistribution of income and wealth due to progressive taxes
29 of 72
Define horizontal equity
Means we give the same treatment to people in an identical situation so income tax is the same for both, reducing discrimination
30 of 72
What actions can the government take against poverty and inequality?
The national minimum wage, progressive taxation, regressive taxation, transfers to the poor, tax credits, means tested benefits, fiscal drag poverty
31 of 72
Define progressive taxes
This is a tax or tax system in which the rich pay a higher proportion of tax than the poor
32 of 72
Define Reressive taxation

33 of 72
Define transfers to the poor
A transfer is an income paid b the state to benefit recipients an is financed through taxation e.g. benefits and pensions
34 of 72
Define tax credits
A form of negative income tax paid by the government to a person on low income
35 of 72
Define fiscal drag
Fiscal drag is a failure to raise personal tax thresholds in line with inflation that brings the lower paid into the tax net
36 of 72
What are the causes of poverty?
Sickness. disability, imperfect information, regressive taxes, low wages, unemployment, old age
37 of 72
How is poverty measured?
There is no official measure but the Joseph Rowntree foundation defines poverty as when a households disposable income is less than 60% of the UK median
38 of 72
Define fuel poverty
Old age pensioners spend a larger proportion of their income on fuel and therefore can suffer from fuel poverty which is when households spend more than 10% of their income on fuel
39 of 72
What is the poverty audit?
An assessment of the governments performance in eradicating poverty
40 of 72
Define the poverty trap
When individuals of households are no better off following a pay increase because tax paid increases and benefits are withdrawn. This reduces incentives
41 of 72
Define relative poverty
This occurs when income is below a specified proportion of the average income. It works by comparing families to others in the population. It is more of an issue in the UK because it is a highly developed economy
42 of 72
Define absolute poverty
This occurs when income is below a particular level it means the same standard is measured across different locations and times it makes comparison easier but doesn't take into account different levels of income reqiured for different locations
43 of 72
Explain markets failing inequitably
It occurs when the signalling, incentive or allocative function breaks down and when there are highly unequal distributions of income and wealth
44 of 72
Define partial market failure
When the market functions but produces the wrong quantity of a product at the wrong price
45 of 72
Define missing markets
When the incentive function of prices doesn't work at all and a market fails to come into existence or disappears completely
46 of 72
Define complete market failure
When the market doesn't supply products at all
47 of 72
Explain markets failing inefficiently
It occurs when the wrong quantity is produced in a market where there are no economies of scale so the wrong price is charged, the market is allocatively and productively inefficient. E.G. monopolies
48 of 72
What is the price mechanism?
the means by which decisions taken by consumers and businesses in order to determine the allocation of scarce resources. It has 3 main functions.
49 of 72
Describe the signalling function
Prices provide information that allows the traders in the market to plan and coordinate their economic activity so higher demand signals to producers to increase production, higher supply signals to consumers that their income has increased
50 of 72
Describe the incentive function
The information signalled by relative prices creates incentives for people to alter economic behaviour
51 of 72
Describe the rationing function
Prices and income rations the way people spend their money as prices ration scarce resources when demand is greater than supply
52 of 72
Define negative externalities
This occurs when the production/consumption of a good imposes external costs on third parties outside the market
53 of 72
Define positive externalities
These occur when the production/consumption of a good imposes external benefits on third parties outside the market, the good may be underconsumed or under provided as the free market fails to value them correctly
54 of 72
Relate externalities and efficiency
There must be no externalities for allocative efficiency to occur. For efficiency to occur P must = MC
55 of 72
Define public bads
A bad for which the producers free ride dumping the bad on third parties
56 of 72
Define Quasi public goods
Goods that are essentially public goods but do not fully exhibit the features non excludable and non rival
57 of 72
Define public goods
Goods that are non exludable and non rival they can lead to market failure
58 of 72
Define private goods
Goods that are excludable and rival
59 of 72
Define merit goods
Goods and services that the government feels that left to the free market people will under consume
60 of 72
Define demerit goods
Goods thought to be bad for you the consumption of demerit goods leads to negative externalities, consumers are unaware of these externalities dues to imperfect information
61 of 72
Define cost benefit analysis
A technique for assessing all the costs and benefits likely to result from an economic decision
62 of 72
Define investment appraisal
A type of CBA used by private sector firms to decide whether to invest, Firms put money values to the costs and benefits. It involves guessing and so can be inaccurate
63 of 72
Define shadow pricing
Cost benefit analysis often uses prices that are different from a goods actual price in order to account for costs and benefits these fake prices are shadow prices
64 of 72
What are the advantages of cost benefit analysis?
Simplicity ( CBA simplifies complex business decisions as it frames everything into total benefits and costs), Objectivity ( CBA provide an objective way to compare projects and removes any emotional attachment),
65 of 72
What are the advantages of cost benefit analysis?
Goal setting (as benefits are predicted it can give a company an idea of the lowest revenue needed to break even)
66 of 72
What are the disadvantages of cost benefit analysis?
Forecasting ( It is hard to forecast all the costs and benefits that might occur as population distribution and inflation might vary), Objectives (CBA can not be used to chose between 2 alternative objectives),
67 of 72
What are the disadvantages of cost benefit analysis?
Social Welfare (social welfare in CBA is found using the Hicks Kaldor test, there welfare gain isn't always spread equally and can be just for the rich) , Varied opinions

71 of 72
Explain public interest theory
This theory supports government intervention in the market as it believes the government intervene with best intentions in order to achieve economic efficiency
