If true, aggregate savings should increase proportionally as gross domestic product GDP grows over time. The idea is to create a mathematical relationship between disposable income and consumer spendingbut only on aggregate levels.
The stability of the consumption function, based in part on Keynes' Psychological Law of Consumption, especially when contrasted with the volatility of investment, is a cornerstone of Keynesian macroeconomic theory. Calculating the Consumption Function The consumption function is represented as: Assumptions and Implications Much of the Keynesian doctrine centers around the frequency with which a given population spends or saves new income.
The consumption function is assumed stable and static; all expenditures are passively determined by the level of national income. For the model to be valid, the consumption function and independent investment must remain constant long enough for national income to reach equilibrium.
At equilibrium, business expectations and consumer expectations match up. One potential problem is the consumption function cannot handle changes in the distribution of income and wealth. When these change, so too might autonomous consumption and the marginal propensity to consume.

His model made adjustments based on how income and liquid cash balances affect an individual's marginal propensity to consume. This hypothesis stipulated that poorer individuals likely spend new income at a higher rate than wealthy individuals. More sophisticated functions may even substitute disposable income, which takes into account taxes, transfers and other sources of income.
