Q

Economic Good

A

Goods and services which use up resources in order to be produced. They therefore have an opportunity cost- in order for one economic good to be produced, another must be foregone. As resources are limited , so is the number of economic goods that can be produced

The quantity of a product that consumers are willing and able to purchase at different market prices over a period of time
27
consumer surplus
The difference between the value a consumer is prepared to pay for a good or service and the price that is actually required to make the purchase (market price)
28
First law of demand
There is an inverse relationship between price and quantity demanded: The lower the price, the higher quantity demanded; the higher the price, the lower quantity demanded
29
Ceteris paribus
All other things being equal
30
Movement along the demand curve
The response to a change in price. An increase shows an extension of quantity demanded and a decrease shows a contraction of quantity demanded
31
Conditions/detriments of demand
Non price factors that affect the level of demand for a good or service
32
Shift in the demand curve
When a change in a non price factor leads to an increase or decrease in demand
33
Increase in demand
Shift outwards; quantity demanded will increase at each and every price
34
Decrease in demand
Shift to the left (inwards); quantity demanded will be less at each and every price
35
PED
The responsiveness of quantity demanded of a good to a change in price eg. %change in quantity demanded --------------------------------------- %change in price
36
Price elastic demand
When quantity demanded is very responsive to a change in price. eg. A 1% change in price will lead to a >1% change in quantity demanded
37
Price inelastic demand
When quantity demanded is not very responsive to to a change in price eg. A 1% change in price will lead to a <1% change in quantity demanded
38
YED
The responsiveness of quantity demanded to a change in income eg. % change in quantity demanded ----------------------------------------- % change in income
39
Normal good
Goods for which an increase income leads to an increase in demand
40
Income elastic demand
When quantity demanded is very responsive to a change in income eg. A 1% change in income will lead to a >1% change in quantity demanded
41
Income inelastic demand
When quantity demanded is not very responsive to to a change in income eg. A 1% change in price will lead to a <1% change in quantity demanded

43
XED
The responsiveness of a quantity demanded of one good to a change in the price of another
44
Complementary good
Goods for which there is joint demand
45
Substitute good
Substitute goods are goods which, as a result of changed conditions, may replace each other in use (or consumption). A substitute good, in contrast to a complementary good, is a good with a positive cross elasticity of demand. This means a good's demand is increased when the price of another good is increased.
46
Total revenue
The price X the quantity sold
47
Effective supply
The quantity of a product that producers are willing and able to supply at different market prices over a period of time
48
Producer surplus
The difference between the price actually received (the market price) by producers for a good/service and the price they are willing to accept
49
Movement along the supply curve
The response to a change in price. An increase shows an extension of quantity supplied A decrease shows a contraction of quantity supplied
50
Conditions of supply
Non-Price factors that affect the level of supply for a good or service
51
conditions of supply
non-price factors that affect the level of supply for a good or service
52
indirect (ad valorem tax)
a tax levied on the consumption of goods and services eg. VAT, APD
53
Incidence of taxation
The way in which the burden of taxation is divided between the buyers and the sellers The more price inelastic the demand curve, the higher the tax incidence on the consumer
54
Subsidy
A payment (usually from government) to encourage production or consumption by lowering the costs of production per unit
55
Price elasticity of supply (PES)
The responsiveness of a quantity supplied of a good/service to a change in its price eg.%change in quantity supplied --------------------------------------- %change in price
56
Determinants of PES
Factors that affect the extent to which quantity supplied is responsive to price Such as availability of stocks of the product, availability of factors of production and the time period
57
Market
Any situation which brings together buyers and sellers (consumers and producers) for the purpose of trading (exchanging) goods and/or services
58
Price system
A method of allocating resources by the free movement of prices
59
Equilibrium quantity
The quantity that is demanded and supplied at the equilibrium price.
60

The price where quantity demanded and supplied are equal
61
Market equilibrium
The price where quantity supplied and demanded are equal
62
Disequilibrium
Any situation position in a market where demand and supply are not equal
63
Shortage
An excess of demand over supply | When quantity demanded > quantity supplied
64
surplus
An excess of supply over demand | When quantity supplied > quantity supplied
65
Market failure
where the free market mechanism fails to achieve economic efficiency.
66
Allocative efficiency
Where scarce resources are used to produce the goods and services that consumers actually demand in the quantities they desire, so consumer welfare is maximised
67
Economic efficiency
where allocative and productive efficiency are achieved
68
Allocative inefficiency
Where resources are over or under-allocated to the production of a particular good or service
69
Externality
Where an action taken by one economic agent has an effect on a third party not directly involved in the activity
70
Negative externality (external cost)
When the actions of of one group result in a negative side effect /impact on a third party OR When the social costs of an activity are greater than the private costs
71
Positive externality (external benefit)
A benefit to a third party OR when social benefits of an economic activity are greater than the private benefits
72
Third party
Person/group of people not directly involved in making a decision
73
Private cost
The costs directly incurred by those undertaking a particular economic activity
74
Private benefit
The benefits directly accruing to those undertaking a particular economic activity
75
Social cost
Private cost + external cost of an economic activity
76
Social benefit
Private benefit + external benefit of an economic activity
77
Socially optimum output
The output quantity where full social cost is equal to full social benefit
78
Information failure
When some, or all, of the participants in an economic exchange do not have perfect knowledge. Or when one participant in an economic exchange has more knowledge than another participant. This leads to the misallocation of scarce resources, resulting in consumers paying too much or too little and/or firms producing too much or too little
79
Asymmetric information
Where information is not equally shared between two parties and therefore one participant in an economic exchange has more knowledge than another.
80
Merit good
A good whose consumption is better for consumers than they actually realise. Hence consumers underestimate the private benefits of consumption and will under-consume this good in a free market
81
Demerit good
A good whose consumption is more harmful than consumers actually realise OR A good that brings less private benefits to consumers than they expect , such that too much will be consumed in a free market
82
Public good
A good which is non excludable and non rivalrous in consumption and will therefore not be provided by the free market due to the free rider problem
83
Non-excludable
Situation where it is technically impossible or financially unviable for individual consumers to be excluded from consuming a good or service (even if they havent paid)
84
Private good
A good which is rivalrous and excludable in consumption
85
Non-rivalrous
Situation where consumption by one person does not reduce its availability for consumption by others
86
Quasi public good
goods that have some, but not all, of the characteristics of a public good
87
Free rider problem
When someone directly benefits from the consumption of a public good without contributing towards its provision
88
Direct provision
The government steps in to supply a good or service
89
Internalising an externality

91
Tradable pollution permits
A permit which allows the owner to emit a certain amount of pollution and which can be sold to another polluter if it is not required
92
provision of information
When the government aims to inform consumers in order to correct market failure eg. providing information on the benefits of merit good/problems of consuming demerit goods and perhaps by advertising or via the curriculum of schools. The government may also try to correct the asymmetric information in this way so that consumers have more power to make more effective choices
93
Regulation
Use of the legal system to place restrictions/ basic standards on producers/consumers. Possible legal restrictions include complete ban, requirement for permit/license or compulsory consumption. This may require enforcement such as fines for non-compliance
94
Property rights system
A system which grants ownership to third parties so that they have the right to sue those creating negative externalities for compensation in order to internalise the externality.
95
Minimum price
A price below which goods and services cannot be sold by law. (eg. the lowest price a unit of alcohol can be sold at.
96
Government failure
A market failure that is the result of a government intervention. For example due to a lack of accurate information, political leaning, need to raise revenue/reduce budget deficit or where costs of administering policy outweigh benefits
97
Consumer expenditure

98
Credit
Loans and borrowings
99
Public good

100
Market failure
When free market forces, using the price mechanism, fail to produce the products that people want, in the quantities they desire and at prices that reflect consumer's satisfaction. In other words, market failure occurs when productive, allocative and thus economic and pareto efficiency are not achieved
