consumption schedulea schedule depicting the relationship between CONSUMPTION EXPENDITURE and the level of NATIONAL INCOME or DISPOSABLE INCOME, also called consumption function. At low levels of disposable income, households consume more than their current income (see DISSAVING), drawing on past savings, borrowing or selling assets in order to maintain consumption at some desired minimum level (AUTONOMOUS CONSUMPTION). At higher levels of disposable income, they consume a part of their current income and save the rest (see SAVING). See INDUCED CONSUMPTION.
