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.
The aggregate expenditure model (sometimes known as the multiplier model or Keynesian cross model) assumes a constant price level, and provides a graphical display of the effects of spending in the econ-omy. The basic idea here is that when Person #1 spends money, it becomes the income of Person #2.
