Macroecon – 1970-80 autonomous spending

1-2 paragraphs addressing the following: 

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.

Using the 10 year period between 1970 – 1980 (during the great inflation years) 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.
