Explain what is meant by the full employment level of National Income

and Equilibrium level of National Income. Why might these levels of

income be different?

National Income is the level of total output, expenditure or income of

an economy over a period of time. The main measure of NY used around

the world today is Gross Domestic Product, or GDP. This is a measure

of all domestic production, that is, production not including trade,

which takes into account the value of indirect taxes such as GST. Full

employment level of National Income means the level of total output

attained when unemployment is at a socially acceptable level. In most

cases this is around 5%, however it does tend to vary. If a government

sets a target unemployment level and this is reached, the economy is

said to be operating at full employment (Nf). Full employment also

includes something called the natural rate of unemployment, which

includes seasonal and frictional unemployment, as well as those

individuals who do not wish to be employed. In other words, the

natural rate of unemployment is the proportion of the workforce which

voluntarily remain unemployed whilst the labour market is in

equilibrium.

We can see, therefore, that full employment may include some

unemployment, although it is usually a small percentage of the working

population. Equilibrium level of employment, however, may have a

larger level of unemployment. The diagram below represents a situation

in which the full employment level is illustrated.

National Income $100b

This diagram presents a situation where the SRAS and the AD curve

intersect on the LRAS and $100b is the NY. The terms used in the

diagram must be explained. SRAS stands for short run aggregate supply,

which is the relationship between the aggregate supply of all final

goods and services and the price level, holding all else constant. In

the short run, the prices of final goods and services can change, but

the factor prices do not. Because of this, it is not possible to

generalise the time period referred to by the word short, as factor

prices can change at any time for numerous reasons. The SRAS is upward

sloping because of the law of diminishing returns, that is some inputs

can increase whilst others may not, and the fact that resource

bottlenecks may occur when the economy moves towards Nf.

AD stands for aggregate demand,, which is the sum of all planned

spending in an economy. The slope of the AD curve is due to the income

effect and the substitute effect. AD is calculated by Consumption +

Investment + Government spending + (Exports – Imports), or
