Macroeconomics - Answer-The study of the economy as a whole, including inflation, growth and
unemployment.
Aggregate demand - Answer-The total of all demands or expenditures in the economy at any
given price.
Aggregate demand curve - Answer-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 - Answer-Business confidence: the mood of managers and owners of firms about
the future of their industry and the wider economy.
Gross investment - Answer-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 - Answer-The addition to the capital stock of the economy.
Retained profit - Answer-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 - Answer-Exports minus imports.
Aggregate supply curve - Answer-The relationship between the average level of prices in the
economy and the level of total output.
Full capacity - Answer-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 - Answer-The upward sloping aggregate supply curve which
assumes that money wage rates are fixed.
Supply-side shocks - Answer-Factors such as changes in wage rates or commodity prices
which cause the short run aggregate supply curve to shift.
Circular flow of income - Answer-A model of the economy which shows the flow of goods,
services and factors and their payments around the economy.
Closed economy - Answer-An economy where there is no foreign trade.
Income - Answer-Rent, interest, wages and profits earned from wealth owned by economic
actors.
Injections - Answer-In the circular flow of income, spending which is not generated by
households including investment, government spending and exports.
,National income - Answer-The value of the output, expenditure or income of an economy over a
period of time.
Open economy - Answer-An economy where there is trade with other countries.
Wealth - Answer-A stock of assets which can be used to generate a flow of production or

and services.
Withdrawals or leakages - Answer-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) - Answer-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) - Answer-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) - Answer-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) - Answer-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 - Answer-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 - Answer-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) - Answer-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

complex mix of variables such as income, health, the environment, participation in society and
political freedoms.
Transfer payments - Answer-Income for which there is no corresponding output, such as
unemployment benefits or pension payments.
Value and volume of national income - Answer-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 - Answer-Economic growth as measured by recorded changes in real GDP over
time.
Boom or peak - Answer-Period of time when the economy is growing strongly and is operating
above its productive potential.
Demand-side shock - Answer-A sudden and large impact on aggregate demand.
Depression or slump - Answer-A period of the trade cycle when there is a particularly deep and
