Assume that the marginal propensity to consume in an economy is 0.9. If the economy's full-employment real GDP is $500 billion and its equilibrium real GDP is $550 billion, there is an inflationary expenditure gap of

$50 billion

Explanation:

Full employment Real GDP = $500 billion

Equilibrium Real GDP = $550 billion

Inflationary expenditure gap = Equilibrium Real GDP - Full employment Real GDP

Inflationary expenditure gap = $550 billion - $500 billion

Inflationary expenditure gap = $50 billion.

Hence, there is an inflationary expenditure gap of $50 billion

Inflationary expenditure gap is the amount by which the Equilibrium Real GDP exceeds the Full employment Real GDP.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
