Answer: Yes, In economics, aggregate expenditure (AE) 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. It refers to the expenditure incurred on consumer goods, planned investment and the expenditure made by the government in the economy.
