Q

Ceteris paribus

1.1.1 - Economics as a social science

A

To simplify analysis, economists isolate the relationship between two variables by assuming ceteris paribus – i.e. all other influencing factors are held constant.

Q

Economic assumptions

1.1.1 - Economics as a social science

A

In his 1953 essay titled “The Methodology of Positive Economics, Milton Friedman explained why economists need to make assumptions to provide useful predictions. Friedman understood economics couldn’t use the scientific method as neatly as chemistry or physics, but he still saw the scientific method as the basis. Friedman stated economists would have to rely on “uncontrolled experience rather than on controlled experiment.”

Q

Unintended consequences

1.1.1 - Economics as a social science

A

Outcomes that are not the ones foreseen and intended by a purposeful action. In government intervention in markets there is usually at least one and often many unintended consequences partly because economics is a social science and we cannot predict accurately how producer and consumers will react.

Q

Normative statements

1.1.2 - Positive and normative economic statement

A

Normative statements express an opinion about what ought to be. They are subjective statements - i.e. they carry value judgments. For example, the level of duty on petrol is unfair and unfairly penalizes motorists.

Q

Positive statement

1.1.2 - Positive and normative economic statement

A

Objective statements that can be tested or rejected by referring to the available evidence. Positive economics deals with objective explanation. For example: “A rise in consumer incomes will lead to a rise in the demand for new cars.” Or “A fall in the exchange rate will lead to an increase in exports overseas.”

Q

Factors of production

1.1.3 - The economic problem

A

Factors of production are the inputs available to supply goods and services:
* Land - Natural resources available for production
* Labour - The human input into the production process
* Capital - goods used in the supply of other products e.g. technology, factories and specialized machinery
* Enterprise - Entrepreneurs organise factors of production and take risks
* Know-how - Information required to develop, produce and bring products to the market.

Q

Concave production possibility frontier

1.1.4 - Production possibility frontiers

A

A concave PPF is “bowed outwards”. This means there is a rising marginal opportunity cost as you produce more of one good. This is because there is imperfect factor mobility. E.g. labour/land/capital is more suited towards the production of one good than another.

Consumer goods and services

1.2.2 - Demand

A

Consumer goods and services help satisfy our needs and wants directly
There is a sub-division between:
* Consumer durables: Products that provide a steady flow of satisfaction / utility over their working life (e.g. a washing machine or using a smartphone).
* Consumer non-durables: Products that are used up in the act of consumption e.g. drinking a coffee or turning on the heating)
* iii) Consumer services: E.g. a hair cut or ticket to a show or sporting event.

Q

Demand curve

1.2.2 - Demand

A

A demand curve shows the relationship between the price of an item and the quantity demanded over a period of time. For normal goods, more of a product will be demanded as the price falls.

77
Q

Diminishing marginal utility

1.2.2 - Demand

A

Marginal utility is the change in satisfaction from consuming an extra unit of a good or service. Beyond a certain point, marginal utility may start to fall (diminish). If marginal utility becomes negative, then consuming an extra unit will cause total utility to fall.

78
Q

Effective demand

1.2.2 - Demand

A

Demand in economics must be effective. Only when a consumers’ desire to buy a product is backed up by an ability to pay for it do we speak of demand.

79
Q

Law of demand

1.2.2 - Demand

A

The law of demand is that there is an inverse relationship between the price of a good and demand. As prices fall, we see an expansion of demand. If price rises, there should be a contraction of demand.

80
Q

Perverse demand curve

1.2.2 - Demand

A

A perverse demand curve is one which slopes upwards from left to right. Therefore,an increase in price leads to an increase in demand. This may happen where goods are strongly affected by price expectations.

Responsiveness of demand for good X following a change in the price of good Y (a related good). With cross price elasticity, we make an important distinction between substitute products and complementary goods and services.

-ve - complements
+ve - subsitues

84
Q

Derived demand

1.2.3 - Price, income and cross elasticities of demand

A

Derived demand is demand that comes from (is derived) from the demand for something else. Thus, the demand for machinery is derived from the demand for consumer goods that the machinery can make. If there is low demand for consumer goods, there is low demand for the machinery that can make them. Demand for bricks is derived from spending on new construction projects.

85

89
Q

Luxury good

1.2.3 - Price, income and cross elasticities of demand

A

Luxury goods and services have an income elasticity of demand with a coefficient of more than +1 i.e. a 5% rise in real incomes might lead to an increase in demand of 20% giving a coefficient of YED of +4

96
Q

Unit elasticity of
demand

1.2.3 - Price, income and cross elasticities of demand

A

A demand curve with unitary price elasticity has a coefficient of PED equal to 1 (unity) throughout. Total spending on the product will be the same at each price level. Government intervention will not affect total spending on the product.

A

When supply is greater than demand and there are unsold goods in the market. Surpluses put downward pressure on the market price.

100
Q

Law of supply

1.2.4 - Supply

A

The law of supply is that there is a positive relationship between the price of a good and supply. As prices rise, we see an expansion of supply. If price fall, there should be a contraction of supply

101
Q

Market supply

1.2.4 - Supply

A

Market supply is the total amount of an item producers are willing and able to sell at different prices, over a given period of time e.g. one month. Industry, a market supply curve is the horizontal summation of all each individual firm’s supply curves.

102

1.2.5 - Elasticity of supply

A

When the coefficient of price elasticity of supply is less than +1. (Pes<1)

108
Q

Price elasticity of supply

1.2.5 - Elasticity of supply

A

Price elasticity of supply (PES) measures the relationship between change in quantity supplied and a change in price. Supply responds positively to price, so PES is always positive.

109
Q

Disequilibrium

1.2.6 - Price determination

A

Prices where demand and supply are out of balance are points of disequilibrium. There is either excess demand (market prices too low) or excess supply (market prices too high).

110
Q

Equilibrium

1.2.6 - Price determination

A

Equilibrium means ‘at rest’ or ‘a state of balance’ - i.e. a situation where there is no tendency for change. The concept is used in both microeconomics (e.g. equilibrium prices in a market) and also in macroeconomics (e.g. equilibrium national income).

111
Q

1.2.6 - Price determination

A

A situation where quantity demanded is greater that quantity supplied.

112
Q

Excess supply

1.2.6 - Price determination

A

A situation where quantity supplied is greater than quantity demanded.

113
Q

1.2.6 - Price determination

A

Health rationing occurs when the demand for health care services outstrips the available resources leading to waiting lists and delays for health treatment.

114
Q

Shortage

1.2.6 - Price determination

A

A situation in which quantity demanded is greater than quantity supplied.

115
Q

Incentives

1.2.7 - Price mechanism

A

For competitive markets to work efficiently economic agents (i.e. consumers and producers) must respond to price signals in the market.

116
Q

Price mechanism

1.2.7 - Price mechanism

A

The means by which decisions of consumers and businesses interact to determine the allocation of resources. The free-market price mechanism clearly does NOT ensure an equitable distribution of resources and can lead to market failure.

117
Q

Price signals

1.2.7 - Price mechanism

A

Changes in price act as a signal about how resources should be allocated. A rise in price encourages producers to switch into making that good but encourages consumers to use an alternative substitute product (therefore rationing the product).

118
Q

Rationing

1.2.7 - Price mechanism

A

A rising price can reduce the quantity demanded of a good or service.

119
Q

Signalling

1.2.7 - Price mechanism

A

Prices have a signalling function because the price in a market sends important information to producers and consumers.

120
Q

Community surplus

1.2.8 - Consumer and producer surplus

A

Community surplus is the sum of consumer and producer surplus at a given market price and output. Community surplus is maximised in competitive markets at an equilibrium output when price = marginal cost.

121
Q

Consumer surplus

1.2.8 - Consumer and producer surplus

A

A measure of the welfare that people gain from consuming goods and services, or a measure of the benefits they derive from the exchange of goods. Consumer surplus is the difference between the total amount that consumers are willing and able to pay for a good or service (indicated by the demand curve) and the total they pay (the market price)

122
Q

Producer surplus

1.2.8 - Consumer and producer surplus

A

The difference between what producers are willing and able to supply a good for and the price they actually receive. The level of producer surplus is shown by the area above the supply curve and below the current market price.

123
Q

Ad valorem tax

1.2.9 - Indirect taxes and subsidies

A

An indirect tax based on a percentage of the sales price of a good or service. An increase in an ad valorem tax causes an inward shift in the supply curve.

124
Q

Alcohol duties

1.2.9 - Indirect taxes and subsidies

A

Excise duties on alcohol are a form of indirect tax and are chargeable on beer, wine and spirits according to their volume and/or alcoholic content.

125
Q

Black market

1.2.9 - Indirect taxes and subsidies

A

An illegal market in which the market price is higher than a legally imposed price ceiling. Black markets can develop where there is excess demand (or a shortage) for a product.

126
Q

Direct tax

1.2.9 - Indirect taxes and subsidies

A

A tax on income and wealth e.g. income tax or corporation tax where the burden of the tax cannot be passed on to someone else.

127
Q

Emission tax

A charge made to firms that pollute the environment based on the quantity of pollution they emit i.e. the volume of CO2 emissions.

128
Q

Excise duties

1.2.9 - Indirect taxes and subsidies

A

Excise duties are indirect taxes levied on our spending on goods and services such as cigarettes, fuel and alcohol. There are also duties on air travel, car insurance.

129
Q

Incidence of a tax

1.2.9 - Indirect taxes and subsidies

A

How the final burden of a tax is shared out. If demand for a good is price elastic and a tax is imposed, then the tax may fall mainly on the producer as they will be unable to put prices up without losing a lot of demand.

130
Q

Indirect tax

1.2.9 - Indirect taxes and subsidies

A

An indirect tax is imposed on producers (suppliers) by the government. Examples include excise duties on cigarettes, alcohol and fuel and also value added tax.

131
Q

Specific tax

1.2.9 - Indirect taxes and subsidies

A

A specific tax is a set tax per unit imposed by the government, a good example is the specific tax (duty) on fuel sold in the UK.

132
Q

Subsidy

1.2.9 - Indirect taxes and subsidies

A

Payments by the government to suppliers that reduce their costs. The effect of a subsidy is to increase supply and therefore reduce the market equilibrium price.

133
Q

Tax incidence

1.2.9 - Indirect taxes and subsidies

A

The manner in which the burden of an indirect tax is shared between participants in the market i.e. consumers and producers.

134
Q

Unit tax

1.2.9 - Indirect taxes and subsidies

A

A specific tax per unit sold e.g. the duty on a litre of fuel might be 80 pence.

135
Q

Behavioural economics

1.2.10 - Alternative views of consumer behaviour

A

Research that adds elements of psychology to traditional models in an attempt to better understand decision-making by investors, consumers and other economic participants.

136
Q

Computational weakness

1.2.10 - Alternative views of consumer behaviour

A

Irrationality arises when consumer’s decisions are dominated by computational weakness. This occurs when consumers find it difficult to calculate the probability of something happening when they make purchasing decisions. For example, people may underestimate the long-term health consequences of eating processed meats or relying heavily on prescription painkillers.

137
Q

Habitual consumption

1.2.10 - Alternative views of consumer behaviour

A

Habitual behaviour occurs when people have strong default choices. Repeat choices / purchases often become automatic because default choices don’t involve much mental (cognitive) effort. To get people to change behaviour may require compelling incentives perhaps from government intervention through taxes and subsidies.

138
Q

Herd behaviour

1.2.10 - Alternative views of consumer behaviour

A

When individuals in a group act collectively without centralised direction.

139
Q

Externalities

1.3.1 - Types of market failure

A

Externalities are third party effects arising from production and consumption of goods and services for which no appropriate compensation is paid.

140
Q

Information gap

1.3.1 - Types of market failure

A

Information gaps exist when either the buyer or seller does not have access to the information needed for them to make a fully informed decision. For example, risks from using tanning salons, the complexity of pension schemes, uncertain quality of second-hand products and knowledge of the nutritional content of foods and drinks.

141
Q

Market failure

1.3.1 - Types of market failure

A

Market failure exists when the competitive outcome of markets is not efficient from the point of view of the economy as a whole. This is usually because the benefits that the market confers on individuals or firms carrying out a particular activity diverge from the benefits to society as a whole.

142
Q

Public goods

1.3.1 - Types of market failure

A

Pure public goods are non-rival – consumption of the good by one person does not reduce the amount available for consumption by another person, and non excludable – where it is not possible to provide a good or service to one person without it being available for others to enjoy.

143
Q

Deadweight loss

1.3.2 - Externalities

A

The loss in producer and consumer surplus due to an inefficient level of production perhaps resulting from market failure or government failure.

144
Q

External benefit

1.3.2 - Externalities

A

A benefit to a 3rd party agent arising from production and/or consumption.

145
Q

External cost

1.3.2 - Externalities

A

External costs are those costs faced by a third party for which no appropriate compensation is forthcoming. Identifying and then estimating a monetary value for air and noise pollution is a difficult exercise - but one that is important for economists concerned with the impact of economic activity on our environment.

146
Q

Externalities

1.3.2 - Externalities

A

Externalities are third party effects arising from production and consumption of goods and services for which no appropriate compensation is paid.

147
Q
A
148
Q

1.3.2 - Externalities

A

Benefit to third parties from the consumption of extra unit of output.

149
Q

Marginal external cost (MEC)

1.3.2 - Externalities

A

Cost to third parties from the production of an additional unit of output.

150
Q

Marginal private benefit (MPB)

1.3.2 - Externalities

A

Benefit to the consumer of consuming an extra unit of output.

151
Q

Marginal private cost (MPC)

1.3.2 - Externalities

A

Cost to the producing firm of producing an additional unit of output.

152
Q

Marginal social
benefit (MSB)

1.3.2 - Externalities

A

Total benefit to society from consuming an extra unit, MSB = MPB + MEB

153
Q

Marginal social cost (MSC)

1.3.2 - Externalities

A

Total cost to society of producing an extra unit of output. MSC = MPC + MEC.

154
Q

Negative
externality

1.3.2 - Externalities

A

Negative externalities occur when production and/or consumption impose external costs on third parties outside of the market for which no appropriate compensation is paid. This causes social costs to exceed private costs.

155
Q

Net social benefit

1.3.2 - Externalities

A

A measurement of the net impact of an investment project found by estimating the social costs and benefits. Net social benefit may be considered by a government when deciding which project(s) offers the best potential return for society.

156
Q

Positive externalities

1.3.2 - Externalities

A

Positive externalities exist when third parties benefit from the spill-over effects of production/consumption e.g. the social returns from investment in education & training or the positive benefits from health care and medical research.

157
Q

Private benefit

1.3.2 - Externalities

A

The rewards to individuals, firms or consumers from consuming or producing goods and services. Also known as internal benefit.

158
Q

Private cost

1.3.2 - Externalities

A

Costs of an economic activity to individuals and firms. Also known as internal costs

159
Q

Social benefit

1.3.2 - Externalities

A

The benefit of production or consumption of a product for society as a whole. Social benefit = private benefit + external benefit.

160
Q

Social cost

1.3.2 - Externalities

A

The cost of production or consumption of a product for society as a whole. Social cost = private cost + external cost.

161
Q

Social efficiency

1.3.2 - Externalities

A

The socially efficient output is where Social Marginal Cost (SMC) = Social Marginal Benefit (SMB).

162
Q

Spill-over effects

1.3.2 - Externalities

A

External effects of economic activity, which have an impact on outsiders who are not producing or consuming a product – these can be negative (creating external costs) or positive (creating external benefits).

163
Q

Excludability

1.3.3 - Public goods

A

Property of a good whereby a person can be prevented from using it if they do not pay.

164
Q

Free rider problem

1.3.3 - Public goods

A

Because public goods are non-excludable it is difficult to charge people for benefitting once a product is available. The free rider problem leads to under provision of a good and thus causes market failure. Free riders have no incentive to reveal how much they are willing and able to pay for a public good
because they can enjoy benefit without paying.

165
Q

Global public goods

1.3.3 - Public goods

A

Global public goods benefit every country, irrespective of which ones provide them – they have become more important recently. Examples might include: Security from war, violence, and crime, the rule of law, property rights, and contract enforcement, eradication of smallpox, Ebola and other diseases.

166
Q

Missing market

1.3.3 - Public goods

A

Missing markets are associated with the difficulties that the free market has in providing pure public goods. Public goods are non-excludable meaning that the benefits derived from them cannot be confined solely to those who have paid for it. Non-payers can enjoy the benefits of consumption at no financial cost to themselves (aka free riders).

167
Q

Non excludability

1.3.3 - Public goods

A

A characteristic of public goods. Benefits derived from pure public goods cannot be confined solely to those who have paid for it. This gives rise to the free-rider problem.

168
Q

Non-rival consumption

1.3.3 - Public goods

A

Non-rivalry means that consumption of a good by one person does not reduce the amount available for others. Non-rivalry is one of the key characteristics of a pure public good.

169
Q

Public goods

1.3.3 - Public goods

A

Pure public goods are non-rival – consumption of the good by one person does not reduce the amount available for consumption by another person, and non excludable – where it is not possible to provide a good or service to one person without it being available for others to enjoy.

170
Q

Quasi-public good

1.3.3 - Public goods

A

A quasi-public good is a near-public good. It has some of the characteristics of a public good. Quasi-public goods are:
* Semi-non-rival: up to a point, more consumers using a park, beach or road do not reduce the space available for others. But eventually beaches become crowded as do parks/leisure facilities. Open-access Wi-Fi networks become crowded.
* Semi-non-excludable: it is possible but difficult or costly to exclude non-paying consumers. E.g. fencing a park or beach and charging an entrance fee; or building toll booths on congested road routes.

171
Q

Tragedy of the Commons

1.3.3 - Public goods

A

When no one owns a resource, it may get over-used, for example fish stocks and deforestation - people use and benefit from a common pool resource such as grazing land without regard to the effects on others. Over-use of a renewable resource can lead to a long-term decline in maximum sustainable yield.

172
Q

Asymmetric information

1.3.4 - Information gaps

A

Where parties have unequal access to information in a market.

173
Q

Information failure

1.3.4 - Information gaps

A

Information failure occurs when people have inaccurate, incomplete, uncertain or misunderstood data and so make potentially ‘wrong’ choices.

174
Q

Symmetric information

1.3.4 - Information gaps

A

For markets to work, there needs to be symmetric information i.e. consumers and producers have the same level of knowledge about the products, and they know everything there is to know about them and the effects of consuming them.

175
Q

Government information

1.4.1 - Government intervention in markets

A

Campaigns and sources of information used in order to correct a market failure and/or influence consumer behaviour. An example would be the ‘Don’t drink and drive’ campaigns.

176
Q

Maximum price

1.4.1 - Government intervention in markets

A

A legally imposed maximum price in a market that suppliers cannot exceed - in an attempt to prevent the market price from rising above a certain level. To be effective a maximum price has to be set below the free market price.

177
Q

Minimum price

1.4.1 - Government intervention in markets

A

A legally imposed price floor below which the normal market price cannot fall. To be effective the minimum price has to be set above the normal equilibrium price.

178
Q

Polluter pays principle

1.4.1 - Government intervention in markets

A

The government may choose to intervene in a market to ensure that the firms and consumers who create negative externalities include them when making their decisions e.g. first parties are forced to internalise external costs & benefits through indirect taxes

179
Q

FF

Pollution permits

1.4.1 - Government intervention in markets

A

Permits allocated in an emissions trading system, for example each permit in the EU trading scheme allows a business to pollute 1 tonne of CO2.

180
Q

Price ceiling

1.4.1 - Government intervention in markets

A

A price ceiling is a regulated maximum price in a market – sellers cannot legally offer the product for sale at a price higher than the ceiling. To be effective, a ceiling must be set below the normal free market equilibrium price.

181
Q

Price floor

1.4.1 - Government intervention in markets

A

A price floor is a minimum price for example a minimum wage in the labour market. Sellers cannot legally under-cut the price floor.

182
Q

Regulated prices

1.4.1 - Government intervention in markets

A

Not all prices are set by the free-market forces of supply and demand. In Britain, a number of prices are affected by regulators who may impose a pricing formula on suppliers. Good examples are rail fares, the cost of postage stamps and water bills.

183
Q

Regulation

1.4.1 - Government intervention in markets

A

Government rules and laws that can control the behaviour of producers or consumers in a market.

184
Q

State provision

1.4.1 - Government intervention in markets

A

Government-provided good or services - funded through tax revenue to provide goods which have positive externalities or are public goods.

185
Q

Government failure

1.4.2 - Government failure

A

Policies that cause a deeper market failure. Government failure may range from the trivial, when intervention is merely ineffective, to cases where intervention produces new and more serious problems that did not exist before.

186
Q

Net welfare loss

1.4.2 - Government failure

A

An overall loss of economic welfare when compared to the starting position.

187
Q

Regulatory capture

1.4.2 - Government failure

A

A form of government failure, happens when a government agency operates in favour of producers rather than consumers

188
Q

Unintended consequences

1.4.2 - Government failure

A

A cause of government failure whereby the government’s actions result in unexpected effects. For example, in the 1960s the government cut spending on railway infrastructure and built roads instead. This caused a significant rise in car transport, which in turn has led to a rise in the demand for trains because the roads are so congested.
