Autonomous Consumption

Autonomous consumption (also exogenous consumption) is consumption expenditure that occurs when income levels are zero. Such consumption is considered autonomous of income only when expenditure on these consumables does not vary with changes in income; generally, it may be required to fund necessities and debt obligations. If income levels are actually zero, this consumption counts as dissaving, because it is financed by borrowing or using up savings. Autonomous consumption contrasts with induced consumption, in that it does not systematically fluctuate with income, whereas induced consumption does. The two are related, for all households, through the consumption function:


  • C = total consumption,
  • c0 = autonomous consumption (c0 > 0),
  • c1 = the marginal propensity to consume (the gradient of induced consumption) (0 < c1 < 1), and
  • Yd = disposable income (income after government intervention (T) – benefits, taxes and transfer payments – equal to Y – T).

Famous quotes containing the words consumption and/or autonomous:

    So it is with books, for the most part: they work no redemption on us. The bookseller might certainly know that his customers are in no respect better for the purchase and consumption of his wares. The volume is dear at a dollar, and after to reading to weariness the lettered backs, we leave the shop with a sigh, and learn, as I did without surprise of a surly bank director, that in bank parlors they estimate all stocks of this kind as rubbish.
    Ralph Waldo Emerson (1803–1882)

    Without free, self-respecting, and autonomous citizens there can be no free and independent nations. Without internal peace, that is, peace among citizens and between the citizens and the state, there can be no guarantee of external peace.
    Václav Havel (b. 1936)
