Aggregate expenditure is the total amount of spending in the economy that determines the level of the GDP. Components of aggregate expenditure are autonomous expenditure, planned private investments, government expenditure, and net exports. When autonomous expenditure increases or decreases, it has a multiplied effect on the GDP.
Referring to the 10-year historical period that you chose for your final project, discuss an example of a change in autonomous spending. Research a government policy implemented during that time and discuss the multiplier effect it had on the economy.
