2. increase taxes by $50 billion.
3. increase taxes by $22.22 billion.

Answer:

tax increased = $22.22 billion

so correct option is 3. increase taxes by $22.22 billion.

Explanation:

given data

real GDP = $500 billion

employment GDP = $300 billion

marginal propensity = 0.9

solution

we know here that Inflationary gap will be

Inflationary gap = Real GDP - Full-employment GDP

Inflationary gap = $(500 - 300) billion

Inflationary gap = $200 billion

and tax Multiplier is

Tax Multiplier  = [tex]\frac{- marginal propensity}{1 - 0.9}[/tex]

Tax Multiplier  = -9

here negative sign means that decrease real GDP by $9

so tax should be increased by $1

so we can say that decrease real GDP by $200 billion

and  tax should be increased = [tex]\frac{200 billion}{9}[/tex]  

tax increased = $22.22 billion

so correct option is 3. increase taxes by $22.22 billion.
