Consumption function

This is the relationship between consumer expenditure and income.

In the Keynesian view, both output and employment are determined by the level of AD.

Total Aggregate Demand = Consumer spending + investment spending + government expenditure on domestically produced final G&S + net exports


AD = C + I + G + X - M


Average Propensity to Consume (APC) is the proportion of personal disposable income consumed.
