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.

INFLATION CAUSES Inflation, the persistent increase in the average price level, can be caused by an increase in aggregate demand or a decrease in aggregate supply. This suggests two basics sources, causes, or types of inflation--demand-pull inflation and cost-push inflation. While short-term bouts of inflation (up to several months) can result from anything (determinant) that might cause either increases in aggregate demand or decreases in aggregate supply, long-term inflation (a year or more) is possible ONLY through persistent increases in the money supply. As such, while demand-pull inflation and cost-push inflation are convenient ways to catalog the transmission mechanisms of inflation, the ultimate CAUSE of inflation is money.
