abstract: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.
Scientists also are far from unraveling the connections between the largely autonomous parts of the brain that regulate day-to-day energy consumption and expenditure, and the conscious brain that directs behavior such as walking across the street to get a bacon cheeseburger.
