AGGREGATE EXPENDITURE LINE: A line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

MONEY FUNCTIONS

Any item used as money in an economy automatically takes on four basic functions: (1) medium of exchange, (2) unit of account, (3) store of value, and (4) standard of deferred payment. While "buying and selling" means that money is THE medium of exchange, and by far THE most important function of money, money also performs unit of account, store of value, and standard of deferred payment functions.
