HIERARCHY OF NEEDS: Developed by Abraham Maslow, the notion that people are motivated to satisfy basic physiological needs (food, shelter, etc.) before moving on to satisfying higher psychological needs (security, companionship, etc.). These alternative needs are layered in a hierarchial pattern with physiological needs on the bottom, safety needs on the second layer, belonging needs on the third layer, esteem needs on the fourth layer, and self-actualization needs at the top. This hierarchy of needs has been used to help explain the progress of human societies from agrarian to manufacturing to service to information.

AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the four macroeconomic sectors (household, business, government, and foreign) and the level of aggregate income or production. In Keynesian economics, the aggregate expenditures line is the essential component of the Keynesian cross analysis used to identify equilibrium income and production. Like any straight line, the aggregate expenditures line is characterized by vertical intercept, which indicates autonomous expenditures, and slope, which indicates induced expenditures. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking investment, government purchases, and net exports to the consumption line.
