In economics, Aggregate Expenditure is a measure of national income. Aggregate Expenditure is defined as the current value of all the finished goods and services in the economy. The aggregate expenditure is thus the sum total of all the expenditures undertaken in the economy by the factors during a given time period.
Expenditures made by each of these sectors are specifically labeled consumption expenditures, investment expenditures, government purchases, and net exports. Aggregate expenditures (AE) are a cornerstone in the study of macroeconomics, playing critical roles in Keynesian economics, aggregate market analysis, and to a lesser degree, monetarism.
