AE LINE: Another term for aggregate expenditure line, which is 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.

PRICE INDEX A measure of the average of a group of prices calculated as a ratio to prices in a given time period (that is, a base year). A price index is primarily used to compare relative prices, or changes in the group prices over time. Such an index is a handy indicator of overall price trends. Two common price indexes that surface in the study of macroeconomics are the Consumer Price Index (CPI) and the GDP price deflator. Both are used to indicate the macroeconomy's average price level and to estimate the inflation rate. The Dow Jones Industrial Average (the Dow), Standard & Poor's 500, and the NASDAQ are well-known indexes of stock market prices.
