General Definitions Flashcards
Positive statement
A statement that does not include a value judgement and can be tested against the facts or
evidence.
Normative statement
A statement that includes a value judgement and cannot be refuted just by looking at data or evidence.
Value Judgement
A view about what is right or wrong, good or bad in a moral sense. Statements that include value judgements often, but not always, contain the words ‘should’ or ‘ought’.
Economic resources (FofP)
The inputs into the production process that are needed to produce the goods and services
that satisfy people’s wants. They are usually classified as land, labour, capital and enterprise.
Economic activity
The production, consumption, exchange and distribution of goods and services.
Land
The factor of production that includes all the natural resources that are available on the earth.
It includes the land and sea.
Capital
The human-made factor of production. Examples of capital include machines, tools, lorries and buildings.
Labour
The human resource. The contribution made by people to the production of goods and services.
Entrepreneur
The person or group of people who organise the other economic resources to allow goods and services to be produced.
Enterprise
Enterprise involves making decisions and taking risks.
Scarce resource
A factor of production that is limited in supply. There are not enough available to satisfy. people’s needs and wants.
Scarcity
The fundamental economic problem that results from limited resources and unlimited wants. It means that choices have to be made which have an opportunity cost.
Opportunity cost
The next best alternative foregone when a choice is made.
Production possibility diagram
Shows the quantities of two goods or services that can be produced with the available resources, given the current state of technology.
Utility
The satisfaction that is derived from consuming a good or service.
Marginal utility
The change in total utility that results from the consumption of one more, or one fewer, goods or services.
Imperfect Information
When an economic agent does not have all the information needed to make a rational decision, or the information is distorted in some way.
Asymmetric information
A type of imperfect information where one party to an economic transaction has more information than the other party.
Demand curve
The relationship between the price and quantity demanded of a good or service, in a given
period of time, when other things that affect demand are held constant.
Price elasticity of demand
A measure of the extent to which the quantity demanded of a product changes in response to a change in the price of the product.
Income elasticity of demand
A measure of the extent to which the quantity demanded of a product changes in response to a change in income.
Cross elasticity of demand
A measure of the extent to which the quantity demanded of a product changes in response to a change in the price of a different product.
Normal good
A product where there is a positive relationship between income and the quantity demanded of the product, eg a rise in income leads to a rise in the quantity demanded.
Inferior good
A product where there is an inverse relationship between income and the quantity demanded of the product, eg a rise in income leads to a fall in the quantity demanded.
Supply curve
The relationship between the price and quantity supplied of a good or service, in a given period of time, when other things that affect supply are held constant.
Price elasticity of supply
A measure of the extent to which the quantity supplied of a product changes in response to a change in the price of the product.
Equilibrium market price
The price at which the quantity demanded equals the quantity supplied and there is no tendency for the price to change.
Disequilibrium price
A price at which there is either excess demand, and a tendency for the price to rise, or there is excess supply, and a tendency for the price to fall.
Excess demand
The amount by which the quantity demanded exceeds the quantity supplied at the current price.
Excess supply
The amount by which the quantity supplied exceeds the quantity demanded at the current price.
Joint demand
When two products are demanded together so that the demand for one product is directly related to the demand for the other product. Complementary goods such as printers and printer cartridges are in joint demand.
Competitive demand
When the demand for one product increases the demand for another product decreases. Substitute goods such as butter and margarine are in competitive demand.
Composite demand
When a product has more than one use so that an increase in the demand for one use leads
to a fall in the supply of the product that is available to use elsewhere. For example, milk is used to produce cream and cheese.
Derived demand
When the demand for a product, or factor of production, is determined by the demand for a different product. For example, the demand for steel is derived from the demand for cars, and a number of other products.
Joint supply
When the output of one product also results in the output of a different product. For example,
sheep farming can lead to the supply of both meat and wool.
Production
The process of using factors of production to create goods and services.
Productivity
A measure of how much a factor of production can produce in a given period of time. For
example, the productivity of land might be measured by output per hectare per year. It is a measure of efficiency.
Labour productivity
A measure of how much a worker can produce in a given period of time. For example, output per person per hour.
Specialisation
Where firms, regions, countries or factors of production concentrate on producing a
particular good or service, or carrying out a particular task.
Division of labour
When the production of a good is broken down into many separate tasks and each worker performs one task, or a narrow range of tasks, as part of the production process.
Short run
The time period when there is at least one fixed factor of production.
Long run
The time period when all factors of production are variable.
The law of diminishing returns
The law states that as more of a variable factor of production is used in combination with a fixed factor of production, both the marginal and average returns to the variable factor of production will initially increase but will eventually decrease.
Returns
The amount produced, ie the output of a good or service.
Marginal returns
The change in total output that results from employing one more unit of a variable factor of production when the amount employed of all other factors of production is unchanged.
Total returns
Total output.
Returns to scale
The effect on total output when all factors of production are changed. It relates to the long run when all factors of production are variable.
Increasing returns to scale
When a given percentage increase in all factor inputs leads to a greater percentage increase in output.
Constant returns to scale
When a given percentage increase in all factor inputs leads to the same percentage increase in output.
Decreasing returns to scale
When a given percentage increase in all factor inputs leads to a smaller percentage increase in output.
Fixed costs
Costs that do not change when output changes.
Variable costs
Costs that change when output changes.
Marginal cost
The change in total cost when one more or one fewer unit of output is produced.
Average cost
Total cost divided by output.
Total cost
Total fixed cost plus total variable cost.
Internal economies of scale
When the growth of a firm results in the firm’s long-run average cost falling.
External economies of scale
When the growth of an industry leads to lower average cost for firms in that industry.
Diseconomies of scale
When the growth of a firm results in the firm’s long-run average cost increasing.
Long run average cost curve
Shows the minimum average costs of producing any given level of output when all factors of production are variable but technology has not changed.
Minimum efficient scale of production
The lowest level of output at which a firm’s long-run average cost is minimised.
Total revenue
The total amount of money a firm receives from selling its output. It is usually calculated by multiplying the price of the product by the quantity sold.
TR = P x Q
Marginal revenue
The change in total revenue when one more or one fewer unit of output is sold.
Average revenue
Total revenue divided by the quantity sold. TR ÷ Q
Profit
The difference between a firm’s total revenue and total cost (TR – TC). The firm makes a profit when TR > TC. It is the reward for the factor of production enterprise.
Normal profit
The minimum amount of profit that is required to keep the entrepreneur in business in the long run. It is the opportunity cost of the entrepreneur. If the cost of enterprise is included as one of the firm’s costs of production, normal profit is earned when total revenue equals total cost.
TR = TC
Abnormal/supernormal profit
When total profit is greater than normal profit.
Technological change
The discovery and use of new and improved methods of producing goods and services. The introduction of new, more efficient technologies shifts the LRAC downwards.
Subnormal profit
When total profit is less than normal profit.
Average returns
Average returns to a variable factor of production is calculated by dividing total output by the number of units of the variable factor that are employed.
Production possibility boundary (PPB)
The PPB is also known as the production possibility curve (PPC) and the production possibility frontier (PPF). It shows the various quantities of two goods or services that can be produced, with the current state of technology, when all the available resources are fully employed.
Resource allocation
How the available factors of production are used to produce different goods and services. The allocation of resources involves determining what is produced, how it is produced and for whom it is produced.
Rational economic decision making
Using all the available information to select the best option to maximise the welfare of the decision maker. A rational consumer chooses to buy the goods and services that, given their limited income, will maximise their total utility.
Hypothesis of diminishing marginal utility
The proposition that as more of a product is consumed, the additional satisfaction gained from each extra unit declines.
Behavioural economics
A branch of economics that includes elements of psychology to improve our understanding of how people’s decision making is influenced by biases and emotional factors.
Bounded rationality
The idea that human limitations mean that people’s decision making is not completely rational. Bounded rationality means that when an individual makes a decision, they choose an option that is satisfactory rather than optimal.
Bounded self-control
The idea that people do not have sufficient willpower or self-discipline to resist choices that may be tempting but are not in their self-interest.
Rules of thumb
Mental shortcuts, based on experience, that enable individuals to make decisions more quickly and easily.
Anchoring
The idea that when making decisions, people rely too heavily on one particular piece of information, the anchor. The anchor is often the first piece of information they encounter.
Availability bias
When people’s decision making is unduly influenced by recent events or how easily an event comes to mind.
Social norms
Behaviours that are consistent with what is generally considered acceptable by society at the present time.
Choice architecture
The way or framework in which choices are presented to people.
Nudge
Something that encourages a particular decision or behaviour without removing freedom of choice.
Default choice
An option that has been pre-selected for an individual but the individual is able to select a different option if they want to.
Restricted choice
Where the number of choices made available to an individual is limited. This type of choice architecture is often adopted when there is a large number of choices available which makes it hard for individuals to decide which is the best option.
Mandated choice
A form of choice architecture where the individual must make a decision. Mandated choices are usually required by law.
Subnormal profit
When total profit is less than normal profit.
Invention
The discovery of something new. It might, for example, be a new product, process or method
of production.
Innovation
The process of introducing and developing a new product, service or method of production.
Market structure
The classification of an industry, or market, in respect of its key characteristics including: the number of firms, the nature of the product and ease of entry.
Divorce of ownership from control
When the people who own a business are not the same set of people who manage, or control, the business.
Satisficing
A decision-making strategy where people/managers aim to achieve an acceptable, or satisfactory, outcome rather than the optimal outcome. For example, managers might aim to achieve a minimum target level of profit rather than to maximise profit.
Market share
The percentage of total sales in a given market that is accounted for by a particular firm or product.
Perfect competition
A market structure that comprises a large number of small firms selling a homogeneous (identical) product to a large number of buyers, none of whom are able to influence the market price. There is perfect knowledge and freedom of entry into the market.
Homogenous products
Products that are identical to each other, they are perfect substitutes.
Price taker
A firm that is unable to influence the price of the product it sells. When a firm is a price taker, the price is usually determined by market forces, ie the interaction of demand and supply.
Monopolistic competition
A market structure that comprises a large number of small firms selling differentiated products to a large number of buyers. There is freedom of entry into the market.
Differentiated products
Products that are similar but not identical to each other. They are close but not perfect substitutes. Products can, for example, be differentiated by the use of brand names, advertising, design, colour and after-sales service. These are types of non-price competition that firms use to differentiate their products and increase their monopoly power.
Price maker
A firm that is able to set the price of the product it sells.
Oligopoly
Oligopoly is a market structure that is often defined as ‘competition amongst the few’. It is not a clearly defined market structure, but a few large firms dominate the market and compete with each other. The market may also contain some small and medium-sized firms. Firms in oligopolistic markets usually produce differentiated products and there are barriers to entry, although the extent to which entry is restricted varies.
Concentration ratio
A measure of the combined market share of the largest firms in an industry, usually expressed as a percentage. For example, a three-firm concentration ratio could be calculated as follows: combined sales of the three largest firms ÷ total sales in the market x 100.
Collusion
Where rival firms work together for their mutual benefit often to the detriment of consumers.
Collusive oligopoly
Where some or all of the large firms in the market work together to increase their monopoly power.
Competitive (non-collusive) oligopoly
Where the firms in the market act individually in their self-interest and use various means to compete with each other.
Kinked demand curve model
A model of oligopolistic behaviour that assumes that if one firm reduces its price others will follow, but if a firm raises its price other firms will not raise their prices. The model attempts to explain why prices are relatively stable and non-price competition usually prevails in oligopolistic markets.
Cartel
A formal agreement between firms to protect their mutual interest and increase their monopoly power. The agreement may involve, for example, fixing prices, restricting output and dividing the market between the firms.
Price leadership
Where one firm changes its price and then other firms in the market follow, making similar price changes.
Price agreements
Where firms cooperate to decide and then fix the prices they will charge for different products and to different consumers.
Price wars
Where firms cut prices aggressively to increase their market share and force other firms out of business. A price cut by one firm, trying to increase its market share, may persuade other firms to cut their prices and start a price war.
Barriers to entry
Factors that make it difficult for new firms to join a market.
Monopoly
Pure monopoly is where a single firm supplies 100% of a market.
Monopoly power
The ability of a firm to affect the price of a product. Firms with monopoly power are price makers and not price takers.
Price discrimination
When a firm charges different prices to different consumers for the same product for reasons other than differences in cost.
Creative destruction
The replacement of existing products, markets and firms with new ones as an inevitable consequence of technological change.
Contestable market
A market in which there are few, if any, barriers to entry or exit, or sunk costs.
Sunk cost
Costs that have been incurred but cannot be recovered if a firm leaves a market. Sunk costs create a barrier to firms leaving an industry.
Hit and run competition
When a firm enters a market to take advantage of the abnormal profits being earned by existing firms (incumbents) and leaves the market when the abnormal profits have been competed away.
Static efficiency
The most efficient allocation of existing resources at a point in time. Static efficiency requires both productive and allocative efficiency.
Dynamic efficiency
The ability of firms and/or an economy to adapt and improve over a period of time. Dynamic efficiency depends on investment, innovation and improved methods of production. It is related to the introduction of new and improved products as well as increases in productivity.
Productive efficiency
Where it is not possible to produce more of one good or service without producing less of another good or service. All points on a production possibility boundary are productively efficient. An individual firm is productively efficient when it is producing at the lowest point on its average total cost curve.
Allocative efficiency
When an economy is producing the combination of goods and services that best satisfies people’s preferences. Whilst all points on a production possibility boundary are productively efficient there might be only one point on the boundary that is allocatively efficient. An individual firm is allocatively efficient when it is producing an output at which price equals marginal cost.
Consumer surplus
The difference between the price a consumer has to pay for a product (usually the market price) and the price the consumer would be willing to pay for a product.
Producer surplus
The difference between the price a firm actually receives for a product (usually the market price) and the price they would be willing and able to supply the product for.
Deadweight loss
The value of producer and consumer surplus that is lost when resources are not allocated efficiently, for example, when a market is not in equilibrium.
Demand curve for labour
The relationship between the wage rate and the number of workers firms wish to employ when other things that affect the demand for labour are held constant.
Marginal physical product of labour
The increase in total output that results from employing one more worker when the amount employed of all other factors of production are unchanged. It is the same as the marginal returns to labour.
Marginal revenue product of labour
The change in total revenue that results from selling the extra output produced by employing one more worker when the amount employed of all other factors of production is unchanged.
Elasticity of demand for labour
A measure of the extent to which the number of workers demanded changes in response to a change in the wage rate.
Supply curve for labour
The relationship between the wage rate and the number of workers willing to work in an occupation when other things that affect the supply of labour are held constant.
Perfectly competitive labour market
A labour market in which there are large numbers of buyers (small firms) and sellers (individual workers) of labour, none of whom can influence the market wage rate. Workers are homogenous/identical, there is perfect information.
Imperfectly competitive labour market
A labour market in which firms have monopsony power and/or there are trade unions that affect the supply of labour and/or there is imperfect information.
Monopsony
A sole buyer of a product or factor of production.
Trade unions
An organisation of workers that aims to protect and promote the rights and interests of its members. A trade union may be able to affect the supply of labour to a particular occupation and exert some monopoly power.
National minimum wage
The lowest wage rate that a firm is legally allowed to pay.
Wage discrimination
When different groups of workers are paid a different wage rate for the same or equivalent work, for reasons other than differences in their marginal revenue product.
Income
The flow of money received by an economic agent over a period of time. Income can be either earned (through employment) or unearned. Unearned income includes interest from savings, dividends, share ownership and rent from property.
Wealth
The value of the stock of assets owned by an economic agent at a point in time.
Equality & Inequality
The extent to which income and wealth are distributed evenly. The degree of equality/inequality can be measured, for example, using the Gini coefficient.
Equity
Related to fairness and justice, it is a normative concept. An equal distribution of income and wealth is not necessarily equitable. What people judge to be equitable will vary.
The Lorenz Curve
A graphical representation of the distribution of income or wealth.
Gini coefficient
A numerical measure of the degree of inequality in the distribution of income or wealth.
Absolute poverty
Where an individual does not have enough income to satisfy their basic human needs.
Relative poverty
Where an individual does not have enough income to enjoy the standard of living that is enjoyed by most people in the society in which they live. Generally, people who have less than 60%, or sometimes 50%, of median income are considered to be in relative poverty.
Rationing function on the price mechanism
When there is excess demand for products and/or factor services, prices rise to reduce demand. When there is excess supply, prices fall to increase demand. Rationing through the price mechanism depends on people’s ability to pay and the strength of their preferences.
Incentive function of the price mechanism
When an increase in price encourages producers, and those providing factor services, to supply more, and a fall in price leads to a reduction in the supply of products and factor services.
Signalling function of the price mechanism
A change in price conveys information to economic agents about changing market conditions in a simple, convenient manner, helping producers and consumers make informed decisions.
Market failure
When markets operating without government intervention result in a misallocation of resources.
Complete market failure
When the market mechanism does not supply a product even though it would satisfy people’s needs and wants. There is a missing market.
Partial market failure
When a market exists and the product is supplied but not at the socially optimal level, too much or too little is supplied.
Public good
A product that is non-rival and non-excludable.
Private good
A product that is both rival and excludable.
Quasi-public good
A product that has some but not all of the features of a public good, for example, it might be non-rival but excludable.
Non-excludable
When no one can be prevented from consuming the product.
Non-rival
When the consumption of the product by one or more individuals does not reduce the amount available for others to consume.
Free rider
When an individual is able to consume a product without paying for it. For example, the non- excludability characteristic of public goods means that public goods are subject to the free- rider problem.
Tragedy of the commons
Where individuals, acting in their self-interest, overuse a shared resource with the result that it is depleted (used up) and degraded (damaged).
Externality
The effects that producing and/or consuming a product have on third parties. When the private cost does not equal the social cost, or when the private benefit does not equal the social benefit of production and/or consumption.
Negative externality
When the social cost is greater than the private cost of production, or when the private benefit is greater than the social benefit of consumption.
Positive externality
When the social cost of production is less than the private cost, or when the social benefit of consumption is greater than the private benefit.
Social cost
The sum of the private cost and the external cost.
Social benefit
The sum of the private benefit and the external benefit.
Property rights
Conveyed through the ownership of a resource/product, giving the owner the authority to decide how it is used.
Merit good
A product that society judges to be especially worthwhile and is likely to be underconsumed because the benefits are not always fully appreciated.
Demerit good
A product that society judges to be undesirable and is likely to be overconsumed because the costs are not always fully recognised.
Immobility of factors of production
When there are barriers that restrict the ability of factors of production to move to a different location (geographical immobility) or to change the type of employment (occupational immobility).
Competition policy
Measures adopted by a government to control the activities of firms to protect consumers, make markets more competitive and encourage an efficient use of resources. It includes the investigation of large firms, the adoption of measures to prevent the abuse of monopoly power, reviewing possible mergers, making markets more contestable and outlawing restrictive practices.
Public ownership
When a firm or industry is owned and controlled by the government. Nationalisation results in the public ownership of firms that were previously in the private sector.
Privatisation
The transfer/sale of state-owned enterprises and other assets from the public sector to the private sector.
Regulation
Laws and government-imposed rules that limit and control the behaviour of firms and individuals.
Deregulation
The removal of rules that restrict the behaviour of firms and individuals, particularly those that limit competition.
Regulatory capture
When organisations regulating industries are excessively sympathetic to the interests of the firms that they are supposed to be regulating. They make decisions that favour the firms they are supposed to be controlling rather than acting in the public interest.
Pollution permits
Licences that are sold or allocated by a government that allow firms to emit a set amount of pollution in a given time period. Permits can be sold to other firms. Pollution permit schemes provide a market-based incentive for firms to reduce pollution.
Subsidy
A payment to producers to reduce costs and increase supply.
Price control
A government regulation that sets a maximum or minimum price that can be charged for a product.
Government failure
When government intervention, with the intention of reducing market failure, leads to a worse allocation of resources than if the government had not intervened. When government intervention reduces economic welfare.
Unintended consequences
The unexpected outcomes that result from the decisions, policies and actions of the government or other economic agents.
National income
The monetary value of all the goods and services that are produced by an economy in a given period of time. It is also equal to total expenditure (C + I + G + X - M) and total factor incomes.

Circular flow of income
A model of the economy that shows how money, goods and services flow between different sectors of an economy, including households, firms, the government and the foreign trade sector.
Injections
Types of expenditure that add to and increase the circular flow of income in an economy. Injections are investment, government spending and exports.
Withdrawals (leakages)
The part of household income that is not spent on goods and services produced by the economy. It is income that is not passed on around the circular flow of income. Withdrawals are saving, taxation and imports.

Macroeconomic equilibrium
The level of real GDP and price level when the planned level of aggregate demand equals aggregate supply.
Demand side shock
An event that leads to a sudden or unexpected change in aggregate demand.
Supply side shock
An event that leads to a sudden or unexpected change in aggregate supply.
Consumption
Spending by households on goods and services to satisfy needs and wants.
Investment
Spending that leads to an increase in the capital stock. Investment is an injection into the circular flow of income.
Exports
Goods and services sold to other countries. Exports are an injection into the circular flow of
income.
Saving
Income that is not spent. Saving is a withdrawal from the circular flow of income.
Taxation
Money that individuals and firms must pay to the government. Taxation helps to finance government sending and is a withdrawal from the circular flow of income.
Imports
Goods and services bought from other countries. Imports are a withdrawal from the circular
flow of income.
Accelerator process
A theory that says investment depends on the rate of change in national income. The theory asserts that an increase in the rate of economic growth (national income) will lead to a proportionately larger increase in investment.
Multiplier
The extent to which a change in injections or withdrawals affects national income. For example, if injections into the circular flow of income increase by £100 million and this leads to a £250 million increase in national income, the multiplier is 2.5.
Marginal propensity to consume
A measure of how a change in income affects consumption. The MPC is calculated by dividing the change in consumption (∆C) by the change in income (∆Y) that caused the change in consumption.
MPC = ∆C ÷ ∆Y
Normal capacity level of output
The maximum output that an economy can continue to produce in the long run. In the short run an economy may produce less than this level of output but can also produce more than its normal capacity level of output. Economic growth will lead to an increase in an economy’s normal capacity level of output.
Short run economic growth
The rate at which the total output of the economy is increasing, usually measured by the annual percentage change in real GDP. Short-run economic growth is greater than long-run economic growth when the amount of spare capacity is falling, and is below long-run economic growth when spare capacity is increasing.
Long run economic growth
The rate at which the productive capacity of the economy is increasing. Long-run economic growth is determined primarily by supply-side factors.
Long-run (underlying) trend rate of economic growth
The average rate at which the productive capacity of the economy is increasing over a number of years, usually 10 or more years.
The economic cycle
The fluctuations in economic activity around an economy’s long-run trend rate of economic growth. The main phases of the economic cycle are: recovery, boom, recession and depression (or slump).
Positive output gap
When a country’s equilibrium level of national income is greater than its normal capacity level of national income.
Negative output gap
When a country’s equilibrium level of national income is below its normal capacity level of national income.
Employment
The number of people who are working, usually in exchange for a wage or salary.
Unemployment
The number of people who are willing and able to work but cannot find a job.
Claimant count
The number of people who are out of work and claiming Job Seekers Allowance.
Labour Force Survey
A measure of unemployment that is based on a sample of households, conducted by the Labour Force Survey. An individual is counted as unemployed if:
* They do not have a job, they want to work, have actively sought work in the last four
weeks, and are able to start work within the next two weeks.
* They are out of work, have found a job, and are waiting to start it in the next two weeks.
Voluntary unemployment
There are jobs available but the individual is not willing to work at current market wage rates.
Involuntary unemployment
When an individual is willing and able to work at current market wage rates but is unable to find employment.
Seasonal unemployment
When people are unemployed at particular times of the year, for example, construction workers are more likely to be unemployed when the weather is bad during the winter.
Frictional unemployment
Short-term unemployment when people are between jobs.
Structural unemployment
Long-term unemployment that occurs when the skills and location of the unemployed workers do not match the jobs available. Structural unemployment persists due to the occupational and geographical immobility of labour.
Cyclical unemployment
Occurs when an economy goes into a recession and people cannot find work because aggregate demand is too low.
Real wage unemployment
Unemployment that results when the wage rate in some labour markets is set above the equilibrium wage rate, for example, as a consequence of a legal minimum wage or a high wage that is the outcome of collective bargaining and trade union power.
Natural rate of unemployment
It is the rate of unemployment that exists when the labour market is in equilibrium. It includes frictional, structural and real wage unemployment.
Price level
The average price of all goods and services in an economy.
Inflation
the rate at which prices of goods and services in an economy are rising.
Deflation
Occurs when the price level is falling, reaches 0%
Disinflation
When an economy is experiencing inflation but the rate of inflation is falling, for example, when the rate of inflation falls from 5% to 3%.
Demand pull inflation
When the rise in the price level is caused by increasing aggregate demand.
Cost push inflation
When the rise in the price level is caused by increasing costs of production.
Short run Phillips Curve
A model of the economy that maintains there is an inverse relationship between unemployment and inflation.
Long run Phillips curve
A model of the economy that maintains that the inverse relationship between unemployment and inflation only exists in the short-run and that if the economy is at the natural rate of unemployment, the rate of inflation will be stable. The model also maintains that if unemployment is above the natural rate, the rate of inflation will fall and if unemployment is below the natural rate, inflation will accelerate.
Money
Primarily a medium of exchange or means of payment, but also a store of value.
Money supply
The stock of money that exists in an economy at a point in time.
Narrow money
Comprises those assets that are generally accepted as a medium of exchange. Narrow money includes cash, commercial banks’ balances at the central bank and demand deposits in the banking system (eg current account deposits).
Broad money
Includes narrow money and some less liquid assets that can be converted easily into assets that are generally accepted as a medium of exchange, for example, deposits in savings accounts that have a notice of withdrawal. Broad definitions of the money supply include narrow money and some assets that are money substitutes.
Financial markets
Where economic agents borrow and lend money, and where they buy and sell financial assets such as shares, bonds, foreign currencies and commodities.
Money market
The market that provides funds to economic agents who require short-term finance.
Capital market
The market that provides medium-term and long-term finance for individuals, firms and governments.
