Aggregate supply curve
2.3.1, 2.3.2, 2.3.3 - Aggregate Supply

Full capacity
2.3.1, 2.3.2, 2.3.3 - Aggregate Supply
The level of output where no extra production can take 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
Long- run aggregate supply curve
2.3.1, 2.3.2, 2.3.3 - Aggregate Supply
The aggregate supply curve which assumes that wage rates are variable, both upward and downards. Classical or supply side economisits assume that wage rates are flexible. Keynesian economists assume that wage rates may be ‘sticky downwards’ and hence the economy may operate at less than full employment even in the long run
Short run aggregate supply curve
2.3.1, 2.3.2, 2.3.3 - Aggregate Supply

Rent. interest, wages and profits earned from wealth owned by economic actors
Injections
2.4.1, 2.4.2 - National income
In the circular flow of income, spending which is not generated by households including investment, government spending and exports
National income
2.4.1, 2.4.2 - National income
The value of the output, expenditure of income of an economy over a period of time

An economy where there is trade with other countries
Wealth
2.4.1, 2.4.2 - National income
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

2.4.4 - The multiplier
The increase in imports divided by the income that caused them
ΔM/ΔY

Marginal propensity to tax (MPT)
The increase in tax revenues divided by the increase in incomme that caused them
ΔT/ΔY
Marginal propensity to withdraw
2.4.3 - Equilibrium levels of real national output
The increase in withdrawals from the circular flow (save, tax, import) divided by the increase in income that caused them; this is the same as the sum of the marginal propensity to save, tax and import (MPS + MPT + MPM)
Multiplier
2.4.3 - Equilibrium levels of real national output
