The study of the economy as a whole, including inflation, growth and unemployment.
Aggregate demand
The total of all demands or expenditures in the economy at any given price.
Aggregate demand curve
Shows the relationship between the price level and equilibrium national income. As the price level rises the equilibrium level of national income falls.
Animal spirits
Business confidence: the mood of managers and owners of firms about the future of their industry and the wider economy.
Gross investment
The addition to capital stock, both to replace the existing capital stock which has been used up (depreciation) and the creation of additional capital.
Investment
The addition to the capital stock of the economy.
Retained profit
Profit kept back by a firm for its own use which is not distributed to shareholders or used to pay taxation.
Net exports or the net trade balance
Exports minus imports.
Aggregate supply curve
The relationship between the average level of prices in the economy and the level of total output.
Full capacity
The level of output where no extra production can take place in the long run with existing resources. The full capacity level of output for an economy is shown by the classical long run aggregate supply curve or the vertical part of a Keynesian aggregate supply curve.
Short-run aggregate supply curve
The upward sloping aggregate supply curve which assumes that money wage rates are fixed.
Supply-side shocks
Factors such as changes in wage rates or commodity prices which cause the short run aggregate supply curve to shift.
Circular flow of income
A model of the economy which shows the flow of goods, services and factors and their payments around the economy.
Closed economy
An economy where there is no foreign trade.
Income
Rent, interest, wages and profits earned from wealth owned by economic actors.
Injections
In the circular flow of income, spending which is not generated by households including investment, government spending and exports.
National income
The value of the output, expenditure or income of an economy over a period of time.
Open economy
An economy where there is trade with other countries.
Wealth
A stock of assets which can be used to generate a flow of production or income. For example, physical wealth such as factories and machines is used to make goods and services.
Withdrawals or leakages
In the circular flow of income, spending by households which does not flow back to domestic firms. It includes savings, taxes and imports.
Marginal propensity to import (MPM)
The increase in imports divided by the increase in income that caused them (i.e. change in M / change in Y)
Marginal propensity to save (MPS)
The increase in saving divided by the increase in income that caused it (i.e. change in S / change in Y)
Marginal propensity to tax (MPT)
The increase in tax revenues divided by the increase in income that caused them (i.e. change in T / change in Y)
Marginal propensity to withdraw (MPW)
The increase in withdrawals from the circular flow (S + T + M) divided by the increase in income that caused them (i.e. change in W / change in Y); this is the same as the sum of the marginal propensity to save, tax and import (MPS + MPT + MPM).
Multiplier or national income multiplier or Keynesian multiplier or real multiplier
The figure used to multiply a change in an injection into the circular flow, such as investment, to find the final change in income (assuming the injection is not determined by income). It is the ratio of the final change in income to the initial change in an injection. It can be calculated as
1 ________ 1 - MPC
or
1 ___________________ MPS + MPT + MPM
or
1 ____ MPW
Multiplier effect or process
An increase in investment or other injection will lead to an even greater increase in income (assuming the injection is not determined by income).
Gross domestic product (GDP)
A measure of the output or value added of an economy which does not include output or income from investments abroad or an allowance for the depreciation of the nation's capital stock.
Gross national income (GNI)
The value of goods and services produced by an economy over a period of time (GDP) plus net overseas interest payments and dividends (factor incomes).
Gross national product (GNP)
The market value of goods and services produced over a period of time through the labour or property supplied by citizens of a country both domestically (GDP) and overseas.
Hidden, black or informal economy
Economic activity where trade and exchange take place but which goes unreported to the tax authorities and those collecting national income statistics.
Net national income
A measure of national income which includes both net income from investments abroad and an allowance for depreciation of the nation's capital stock.
Per person or per head or per capita
Per individual in the population
Purchasing power parities
An exchange rate of one currency for another which compares how much a typical basket of goods in one country costs compared to that of another country.
Standard of living
How well off is an individual, household or economy, measured by a complex mix of variables such as income, health, the environment, participation in society and political freedoms.
Transfer payments
Income for which there is no corresponding output, such as unemployment benefits or pension payments.
Value and volume of national income
The value of national income is its monetary value at the prices of the day; the volume is the national income adjusted for inflation and is expressed either as an index number or in money terms at the prices in a selected base year.
Actual growth
Economic growth as measured by recorded changes in real GDP over time.
Boom or peak
Period of time when the economy is growing strongly and is operating above its productive potential.
Demand-side shock
A sudden and large impact on aggregate demand.
Depression or slump
A period of the trade cycle when there is a particularly deep and long fall in output.
Downturn
A period of the trade cycle when either economic growth or GDP itself is falling.
Economic growth
The rise in output in an economy which can be either actual growth or potential growth.
Economic recovery
The movement back from where the economy is operating below its productive potential to a point where it is at is productive potential.
Export-led growth
A rise in aggregate demand caused by a rise in exports.
Hysteresis
The process whereby a variable does not return to its former value when changed. In terms of the trade cycle, it is used to describe the phenomenon of an economy failing to return to its former long term trend rate of growth after a severe recession.
Output gap
The difference between the actual level of GDP and the productive potential of the economy.
Positive output gap
When actual GDP is above the productive potential of the economy and it is in boom.
Negative output gap
When actual GDP is below the productive potential of the economy.
Potential growth
Economic growth as measured by the changes in the productive potential of the economy over time.
Recession
A period of the trade cycle when output or growth in output falls. The technical definition now used by the UK government is that a recession occurs when growth in output is negative for two consecutive quarters (i.e. two periods of three months).
Spare capacity
For a whole economy, this exists when long run aggregate supply is greater than aggregate demand and so there is a negative output gap.
Supply-side shock
A sudden and large impact on aggregate supply.
Trade or business or economic cycle
Regular fluctuations in the level of economic activity around the productive potential of the economy. In business cycles, the economy veers from recession, when it is operating well below its productive potential, to booms when it is likely to be at or even above its productive potential.
Sustainable growth
Growth in the productive potential of the economy today which does not lead to a fall in the productive potential of the economy for future generations.
Anticipated inflation
Increases in prices which economic actors are able to predict with accuracy.
Consumer Prices Index (CPI)
A measure of the price level used across the European Union and used by the Bank of England to measure inflation against its target.

A measure of the price level which has been calculated in the UK for over 60 years and is used in a variety of contexts such as by the government to index welfare benefits.
Unanticipated inflation
Increases in prices which economic actors like consumers and firms fail to predict accurately and so their decisions are based on poor information.

Budget
A statement of the spending and income plans of an individual firm or government. The Budget is the yearly statement on government spending and taxation plans in the UK.
Budget deficit
A deficit which arises because government spending is greater than its receipts. Government therefore has to borrow money to finance the difference.

A government surplus arising from government spending being less than its receipts. Government can use the difference to repay part of the National Debt.
Contractionary fiscal policy
Fiscal policy which leads to a fall in aggregate demand.
