24
Price Elasticity of Supply
The responsiveness of the quantity supplied of a product to its change in price.
25
Factors Effecting PES
- production period time - spare capacity - durability of goods
26
Price Mechanism
A system where the forces of demand and supply determine prices and how resources are allocated.
27
Market Failure
A sub-optimal allocation of resources such that living standards are not maximised.
28
Profit Motive
Producers aim to make as much profit as possible, regardless of the impact on the consumer.
29
Purchasing Power
The volume of goods/services a household can buy with a set income.
30
Economics
A social science which studies the decision making of individuals, businesses, and governments in allocating scarce resources.
31
Relative Scarcity
The fundamental economic problem of having unlimited needs and wants but only a finite amount of resources to satisfy them.
32
Microeconomics
The study of the individual decision making of households and businesses.
33
Macroeconomics
The study of large scale economic factors such as inflation or unemployment.
34
Ceteris Paribus
“Other things equal”; a concept that shows the cause and affect between two factors (e.g. price and demand) while keeping all other variables constant (e.g. weather).
35
Diminishing Marginal Utility
The more good/service that is consumed, the less satisfaction is gained.
36
Need
A good/service that is necessary for survival (e.g. shelter).
37
Want
A good/service that adds to quality of life but is not necessary for survival (e.g. new phone).
38
Factors of Production
The three types of resources - land, labour (entrepreneurship) and capital - used to create goods/services.
39
Land Resources
All resources found in nature, such as trees, crops, minerals, land, animals and water.
40
Labour Resources
The mental (e.g. teaching) and physical (e.g. construction) effort exerted by humans in the production process
41
Capital Resources
The tools used in the production process, such as machinery, factories or AI.
42
Entrepreneurship Resources
The individuals who take financial risks to establish businesses that produce goods/services.
43
Three Basic Economic Questions
What to produce? How to produce? For whom to produce?
44
Market
A place that allows for the exchange of goods/services between buyers and sellers.
45
Opportunity Cost
The value of the next best alternative forgone when a decision is made.
46
Production Possibility Frontier (PPF/C)
A graph illustrating the possible resource allocations to two goods in an economy.
47
Allocative Efficiency
A hypothetical economy where resources are allocated to achieve the highest levels of satisfaction. Resources will be produced in the right quantities and go to the people who value them most.
48
Technical Efficiency
The point where maximum output is being achieved without increasing input.
49
Dynamic Efficiency
The ability of an economy to reallocate its resources quickly.
50
Inter-Temporal Efficiency
The balancing of resource consumption over time (e.g. not cutting down too many trees).
51
Monopoly
A market structure where a single producer has complete control over the market.
52
Oligopoly
A market structure where the market is shared by a small number of producers with little competition. Other firms cannot enter the market. E.g. airline industry
53
Material Living Standards
The ability of households to access goods/services, measured by real GDP.
54
Non-Material Living Standards
Non-material factors that affect an individual's quality of life, such as social networks, freedom of speech, and a healthy environment.
55
Public Goods
Products that are non-excludable and non-rivalrous in consumption. (e.g. street lights, defence, radios). Result in a market failure where there is an under allocation of resources. Fixed through government subsidies or direct government provision.
56
Private Goods
Products that are excludable and rivalrous in consumption, such as a chocolate bar.
57
Rivalrous/Depletable
The consumption of the product by one person diminishes the quantity available for others. (e.g. eating a chocolate bar)
58
Excludable
There is a way to prevent people who have not paid for the product from using it. (e.g. fence at a zoo)
59
Non-Rivalrous
The consumption of the product by one person does not diminish the quantity available for others. (e.g. standing under a street light)
60
Non-Excludable
It is difficult to prevent people who have not paid for the product from using it. (e.g. beach)
61
Free Rider Problem
A type of market failure associated with public goods, when a consumer is benefiting from goods/services that they have not paid for. Results in under allocation of resources.
62
Subsidy
A sum of money granted by the government to a business or individual for financial assistance.
63
Positive Externality in Production
When a firm produces a product that benefits a third party not involved in the process. (e.g. research) Private costs > social costs Gov intervention includes: regulation, advertising, subsidies, direct provision
64
Positive Externality in Consumption
When the consumption of a product improves the wellbeing of a third party not involved in the activity. (e.g. vaccines) Social benefits > Private benefits Gov intervention includes: regulation, advertising, subsidies, direct provision
65
Negative Externality in Production
When a firm produces a product that imposes a cost on a third party not involved in the process. (e.g. pollution from factories) Private costs < social costs Gov intervention includes: indirect taxes, subsidies of alternatives, advertising
66
Negative Externality in Consumption
When the consumption of a product lowers the wellbeing of a third party not involved in the activity. (e.g. smoking) Social benefits < Private benefits Gov intervention includes: indirect taxes, subsidies of alternatives, advertising
67
Asymmetric Information
A type of market failure where one party in a transaction has more information than the other party. (e.g. used cars market, insurance)
68
Moral Hazard
A market failure caused by asymmetric information when an economic agent takes unnecessary risk because another party pays for the consequences (e.g. insurance)
69
Adverse Selection
A market failure caused by asymmetric information where a seller does not disclose information about a product, resulting in a buyer purchasing a faulty product. (e.g. used car). Results in an overallocation of resources.
70
Merit Goods vs Demerit Goods
Merit = positive for society but under consumed (e.g. education) Demerit = bad for society and over consumed (e.g. smoking)
71
Common Access Resources
Products that are non-excludable and rivalrous in consumption, such as a forest. Results in inter-temporal inefficiency where too many CARs are consumed.
72
Government Failure
A situation where government intervention into a market fails to improve the allocation of resources.
73
Price Ceiling
A government price control that bans sellers of products from raising their prices above a certain level. (e.g. rent) Can lead to shortages and a black market.
74
Price Floor
A government price control that mandates that the price of a product must not go below a certain level (e.g. minimum wage). Can lead to an ongoing surplus that then has to be bought by the government.
76
Types of Government Failure
- price controls (ceiling/floor) - subsidies & indirect taxes - protectionism - moral hazard
