Due to a scarcity of resources
27
Definition of specialisation

42
What are the 4 basic types of elasticity?
- price elasticity of demand (PED) - price elasticity of supply (PES) - income elasticity of demand (YED) - cross elasticity of demand (XED)
43
What is the equation for “Price Elasticity of Demand” (PED)?

Name 3 economic theorists
Adam Smith (1723-1790) Capitalism / Mixed Economy Karl Marx (1818-1883) Communism / Centralised Economy Friedrich Heyak (1899-1992) Free Market / Free Economy
48
Which theory did Adam Smith develop?
The invisible hand theory: - Self Interest - Circular Flow of Income - Risk & Reward - Trade leaves us all better off - Wealth is created through productive labor, and that self-interest motivates people to put their resources to the best use.
49
Which theory did Karl Marx develop?
Marxism - Capitalists control the capital. - The capitalists are motivated by profit so pay poor wages which affects spending. - Marx believed sharing the wealth was a better idea.
50
Which theory did Friedrich Hayek develop?
- Only Buyers & Sellers understand the market. - The government might try to help. - But any policy unintentionally makes things worse. - Better off leaving the market alone. - Believes the only place for government is passing essential laws (Like Health and Safety), collecting general taxes (Like VAT). - Then letting the market take care of itself!
51
Definition of elastic
A product is considered to be elastic if the quantity demand of the product changes more than proportionally when it’s price increases or decreases
52
Definition of inelastic
When the price of a good/service changes, consumers’ buying habits stay about the same
53
Determinants of Elasticity of Demand (SPLAT)
- **S**ubstitutes (no. and closeness) - **P**ercentage of increase - **L**uxury / necessity - **A**ddictive / habit-forming - **T**ime period
54
What is the equation for Price Elasticity of Supply (PES)?
(%change in quantity supplied) / (%change in price) = PES
55
Determinants of Elasticity of Supply? (PEPS T)
- **P**ace of technological advancement - **E**ase of switching between products in production - spare **P**roduction capacity (CELL) - spare **S**torage capacity - **T**ime period for production adjustment
56
What is the equation for Income Elasticity of Demand?
(%change in quantity demanded) / (%change in income) = YED
57
(For YED and CE) What do the values mean? (6)
> 1 = elastic < 1 = inelastic > 1 = luxury < 1 = necessity Negative - inferior good (and a substitute good) Positive - normal (and a complimentary good)
58
Definition of recession
2 consecutive periods of negative growth (6 months)
59
Definition of cross elasticity
The responsiveness of demand of one good to changes in the price of a related good - either a substitute or a complementary good/service
60
What is the equation for Cross Elasticity of Demand?
(%change in quantity demanded of good A) / (%change in price of good B) = XED
61
What does a negative symbol in front of the XED value mean?
Substitute (positive relationship)
62
What does a positive symbol in front of the XED value mean?
Complementary (inverse relationship)
63
The higher the the value of XED…
…the stronger the relationship
64
Definition of market failure
When the market fails to allocate resources effectively
65
Definition of negative externalities
When a 3rd party is negatively effected by a market transaction
66
What do the following stand for? - MPC - MPB - MSC - MSB
MPC - marginal private cost MPB - marginal private benefit MSC - marginal social cost MSB - marginal social benefit
67
What does the triangle show in a negative externalities graph?
The negative externalities (the extra cost to society)
68
Which line is added in a negative externalities graph (and direction)?
Marginal Social Cost (MSC) - bottom left to top right
69
Definition of positive externalities
When a 3rd party is positively effected by a market transaction
70
Which line is added in a positive externalities graph (and direction)?
Marginal Social Benefit (MSB) - top left to bottom right
71
Definition of Price Mechanism
The interaction of buyers and sellers in free markets to enable goods, services and resources to be allocated by prices
72
What are the functions of the price mechanism (3)?
- rationing function - signalling function - incentive function
73
What is the rationing function?
Resources are scarce —> demand exceeds supply + price goes up The greater the scarcity, the higher the price and the more the resource is rationed
74
What is the signalling function?
Higher prices —> signals to consumers to reduce consumption + signals to firms to produce more Falling prices —> signals to consumers to enter a market + signals to producers to leave a market
75
What is the incentive function?
Higher prices —> incentive for consumers to consume less + incentive for producers to produce more Falling prices —> incentive for consumers to consume more + incentive for producers to produce less
76
Definition of rational decision making
(The assumption that) people aim to maximise their own welfare
77
Reasons why humans are irrational decision makers (10)
- incomplete information - limited capacity to calculate all costs and benefits - limited computation - influenced by social networks - often act reciprocally rather than self interests - lack self control and seek immediate satisfaction - loss averse - make different choices in cold/emotional states - often fall back on simple rules of thumb when choosing - satisfice rather than maximise - have a strong default to maintain the status quo
78
Complete market failure is…
When there is no supply of products
79
Partial market failure is…
When the market functions but produces the wrong quantity of a product or the wrong price
80
What are public goods?
Examples of missing markets/market failure
81
Market failure leads to…
Government intervention
82
What is another name for ‘public goods’?
‘Collective consumption goods’
83
What are the 3 features of ‘public goods’?
- non-excludability - the benefits derived from pure public goods cannot be confined solely to those who have paid for it - non-rival - consumption by one consumer doesn’t restrict consumption by other consumers - non-rejectable - cannot be rejected by people
84
What is the ‘free-rider’ problem?
Public goods are non-excludable so it is hard to charge everyone for using them. The government pays for the public good with taxation so everyone is charged.
85
Definition of maximum pricing
When a price is set which the market will not be allowed to go above
86
What are some sectors that the government like because of their positive externalities (4)?
- rental market - elderly care - health/dental care - education market
87
The maximum price has to be set… the current market price.

The minimum price has to be set… the current market price.
…above…
90
What are some products which if minimum priced, society would benefit (4)?
- sugar - energy drinks - cigarettes/vapes - alcohol
91
Definition of flat tax
A tax on firms, that imposes the same tax rate on all individuals, regardless of their income levels (but can be passed on to costomers through higher prices)
92
Examples of industries which would benefit from flat tax (6)?
- cigarettes/vapes - sugar - fuel - gambling - fast food - alcohol/energy drinks
93
Definition of ad valorem (unit tax)
a tax that is based on the value of a product or service (% tax)
94
Main example of ad valorem tax
VAT
95
In a flat tax graph, the supply line… and the demand line…
…shifts to the left… …doesn’t move…
96
In an ad valorem graph, the supply line… and the demand line…
…tilts to be more vertical… …doesn’t move…
97
Definition of a quasi-public good
A near-public good i.e. it has many but not all the characteristics of a public good
98
Examples of quasi-public goods (3)
- beaches - parks - swimming pools
99
Definition of merit good
Goods/services that the government feels people will under-consume and ought to be subsidised or provided free at the point of use so that consumption doesn’t depend primarily on the ability to pay for the good/service
100
Reasons why education is seen as a merit good (7)
- more efficient/productive workforce - government can collect more tax - people can have a higher choice of jobs and opportunities - people can earn higher income - the prices of goods decrease due to increased supply - occupational mobility - reduces unemployment
101
Definition of demerit goods
‘Bad for you’ goods Market fails to take into account the negative externalities of consumption because the social costs exceeds the private costs
102
Examples of demerit goods (3)
- drugs - alcohol - cigarettes/vapes
103
Definition of asymmetric information
Type of market failure in which one party has more information than the other party. They use this to exploit the other party.

106
What is carbon trading?
A system of limiting carbon emissions through granting firms permits to emit a certain amount of carbon
107
What are the advantages to a firm of producing less carbon than the government has permitted them to?
The firm can buy and sell these permits on the open market They can then use this money to invest in their business
108
Reasons why young people have such high car insurance payments (6)
- less experience - more often have accidents - drive at peak times - learning to drive - live in bigger cities (London) - type of car they drive
109
Factors that may increase the price of someone’s insurance (5)
- postcode (London/area of high levels of crime) - lack of experience - young age - car’s mileage and type of car - previous convictions/behaviour
110
What is the black box scheme?
A type of car insurance which sees a small device fitted out-of-sight in your car and it measures how well you drive in order to reward safe drivers with discounted insurance.
111
What is ‘consumer surplus’?
The difference between the total amount that consumers are willing to pay and the total amount they actually have to pay.
112
What is ‘producer surplus’?
The difference between the price the producer is willing to accept and the actual amount they receive.
113
What is the combined consumer surplus and producer surplus called?
Welfare gain to society
114
In a consumer surplus and producer surplus diagram, which triangle is which?
The top one - consumer surplus The bottom one - producer surplus
115
What does consumer/producer surplus diagrams tell us?
How much a good/service benefits society and how much the welfare gain is
