AUTONOMOUS SAVING: Household saving that is unrelated to income or production (especially disposable, national income, or gross national product). This is saving that would occur even if household disposable income was zero. Autonomous saving is graphically depicted as the vertical intercept of the saving or propensity-to-save line. Autonomous saving is the equal to the negative value of autonomous consumption. Changes in autonomous saving, along with changes in autonomous expenditures, are what trigger the multiplier effect.
