A
‘with all other things equal’

7
Q
command economy
A
all factors of production are allocated by the state, so they decide what, how and for who to produce goods
8

14
Q
Demand
A
the quantity of a good/service the consumers are willing and able to buy at a given price at any moment in time
15
Q
Diminishing marginal utility
A
- the extra benefit gained from consumption of a good generally declines as extra units are consumed

16
Q
marginal utility
A
the happiness in consumption gained from the next unit consumed
17
Q
Division of labour
A
when labour becomes specialised during the production process so workers do a specific task in cooperation with other workers
18
Q
Economic problem
A
- The problem of scarcity
- wants are unlimited but resources are finite so choices have to be made

when resources are allocated optimally, so every consumer benefits and waste is minimised
20
Q
Enterprise
A
- one of 4 factors of production
- the willingness and ability to take risks and combine the three other factors of production
21
Q
Equilibrium price/quantity
A
where demand = supply so there are no more market forces bringing about change to price or quantity demanded
22
Q
Excess demand
A
when price is set too low so demand is greater than supply
23
Q
excess supply
A
when price is set too high so supply is greater than demand
24
Q
externalities
A
the cost or benefit a third party receives from an economic transaction outside of the market mechanism
25
external cost/benefit
- the cost/benefit to a third party not involved in the economic activity
- the difference between social cost/benefit and private cost/benefit
26
free market
an economy where the market mechanism allocates resources so consumers and producers make decisions about what is produced, how to produce and for whom.
27
free rider principle
people who do not pay for public goods still receive benefits from it so the private sector will under- provide the good as they cant make a profit
28
government failure
when government intervention leads to a net welfare loss in society, worsening allocation of resources
- costs of intervention outweigh benefits
29
habitual behaviour
- a cause of irrational behavior
- when consumers are in the habit of making certain decisions
30
incentive function
acts as an incentive to work hard. with ↑ money, buyers can buy more. if suppliers produce ↑ , they will earn more.
low prices incentive for consumers to buy more, high prices incentive for consumers to sell more.

- natural resources such as oil, coal, wheat, physical space
40
luxury goods
YED > 1
- an increase in incomes causes an even bigger increase in demand
41
market failure
when the market fails to allocate resources efficiently, so there is an inefficient allocation of scarce resources leading to loss in social welfare
42
Market forces
forces in free market which act to reduce prices when there is excess supply and increase them when there is excess demand
43
market clearing price
where all goods supplied to market are bought, but no buyers are unable to buy the good
44
maximum price
a ceiling price which a firm cannot charge above
45
minimum price
a floor price which a firm cannot charge below
46
mixed economy
both the free market mechanism and the government allocate resources
47
model
- a hypothesis which can be proven or tested by evidence

48
-ve externalities of production
where the social costs of producing a good are greater than the private costs of producing the good
49
non-excludable
- a characteristic of public goods
- someone cannot be prevented from using the good
50
Non-renewable resources
- resources that cannot be readily replenished or replaced at a level equal to consumption
- the stock level decreases over time as they are consumed
51
non-rivalry
- a characteristic of public goods
- one persons use of the good does not prevent someone else from using it
52

where the social benefits of consuming a good are larger than the private benefits of consuming that good
58
positive statement
objective statements which can be tested with factual evidence to be proven or disproven
59
Possibility Production Frontier (PPF)
depicts the maximum productive potential of an economy, using a combination of two goods or services, when resources are fully and efficiently employed
60

64
Price mechanism
the system of resource allocation based on the free market movement of prices, determined by the demand and supply curves
65
private cost/benefit
the cost/benefit to the individual participating in the economic activity

the difference between the price the producer is willing to charge and the price they actually charge
68
public goods
goods that are non-excludable and non-rivalrous
69
rationality
decision making that leads to economic agents maximising their utility
70
rationing function
when price ↑, some ppl cant afford, and some have no desire to buy anymore.
means limited resources can be allocated to those who can afford and still want
71
regulation
laws to address market failure and promote competition between firms
72
regulatory capture
when govt try regulate monopoly power.
occurs when interests of society are overlooked for interests of CEOs and managers etc.
when CEOs/managers influence regulator, due to close contact/used to work in industry before so knows CEOs in industry.
means Ceos can influence regulator to reduce extent of the regulation
working in interest of firm not of society.
73
relatively price elastic good
- when PED/PES > 1
- demand/supply is relatively responsive to a change in price so a small change in price leads to a large change in quantity demanded/supplied
74
relatively price inelastic good
- when PED/PES < 1
- demand/supply is relatively unresponsive to a change in price so a small change in price leads to a small change in quantity demanded/supplied
75
renewable resources
resources which can be replenished, so the stock of resources can be maintained over a period of time
76
scarcity
the shortage of resources in relation to the quantity of human wants
77
signalling function
signals to producers where their resources should be used. if P↑, resources should go there. the price change shows the market has changed, so they should change the quantity bought/sold to reach equilibrium
78
social cost/benefit
the cost/benefit to society as a whole due to the economic activity
79
social optimum position
- where social costs equal social benefits
- the amount which should be produced/consumed in order to maximise social welfare
80
social science
the study of societies and human behaviour
81
specialisation
the production of a limited range of goods by a company/country/individual so they arent self sufficient and have to trade with others
82
specific tax
a tax imposed on a good where the value of the tax is dependent on the quantity that is bought
83
state provision of goods
through taxation, the govt provides public goods or merit goods which are underprovided in the free market
84
subsidy
govt. payments to a producer to lower their costs of production and encourage them to produce more
85
substitutes
- positive XED
- if good B becomes more expensive, demand for good A rises
86
supply
the ability and willingness to provide a particular good/service at a given price at a given moment in time
87
symmetric information
where buyers and sellers both have access to the same info
88
trade pollution permits
licenses which allow businesses to pollute up a certain amount.
the govt controls the number of licenses and so can control the amount of pollution.
Businesses are allowed to sell and buy the permits which means there may be incentive to reduce the amount they pollute
89
Unitary price elastic good
when PED/PES = 1
- a change in price leads to a change in output by the same proportion
90
Utility
the satisfaction derived from consuming a good
91

I - income
F - fashion/taste
I - interest rates
C - complements price
95
income effect
- when the price falls people's 'real income' increases so they can afford to buy more
96
substitutes effect
- when the price of a product falls the product will be relatively more attractive to people than other products whose prices have remained unchanged
97
Pareto optimality
when a market is at equilibrium with no external influences its said to be at 'Pareto optimality'

104
economic growth
an increase in the productive capacity of the economy indicating an increase in real output
105
