A major cause of economic growth from the aggregate demand-side of the economy (represented by the equation Y = C + I + G + X – M) is consumption expenditure (C), which refers to the spendings by households on goods and services, and is the largest contributor to a nation’s GDP, accounting for 60% of total expenditure. The prime determinant of consumption spending is the level of disposable income as suggested in Keynesian economics where there exists a direct relationship between the level of income and the level of consumption, such that an increase in income levels accompanies an increase in consumption; and as the level of income falls, the level of consumption falls. Such relationship is represented through the consumption function equation Y = Co + cY and diagrammatically (as in figure __) illustrating the amounts households are willing to spend at every income level.

This slow / low wages growth was a result of numerous factors including the commodity boom slowdown (2011-2012) and the transition towards the services sector (e.g. education and health services, recreational tourism) whereby, the nature of work is based predominately on part-time and casual hours and thereby, workers have less job security and bargaining power, thus leading to slowed rates of wages growth. This has resulted in a reduction in the larger wage rises (over 4%) from 3.7% (2012) to 2.2% (2016)). Due to this, consumption expenditure has slumped from 7% (2007-2008) to 2% (2019) (as shown in figure ...... from C1 to C2), reducing its contribution to aggregate demand, and as the household sector plays a crucial role in determining the level of AD, it therefore has suppressed the rate of growth (as measured by national income from Ye1 to Ye2 in figure ....) given, the simple multiplier effect [PUT THE MULTIPLIER DEFINITION / COMMENT HERE]** .
