Answer:
$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.
