Suppose that marginal propensity to consume is equal to 0.9 and the government increases its spending by $200 billion. This new increase in spending is financed by a fresh increase in taxes equal to $200 billion. As a result of this, GDP will:

A. not change at all.
B. increase by $200 billion.
C. increase by $2,000 billion.
D. decrease by $200 billion.

The answer is B.

Explanation:

Gross Domestic Product (GDP) is the total market value of all the final goods and services produced within a sovereign nation(country) during a given period of time usually a year.

Gross Domestic Product (GDP) can be calculated using expenditure method or income method or value-added method.

To analyze this question, expenditure method will be used. The formula is C + I + G + (X-M)

where C is the consumer spending

I is the business investments

G is the government spending

X is the exports

M is the imports.

Government has injected $200 billion into the economy through its spending.

This $200 billion is gotten from an increase in taxes, meaning consumers' disposable income has reduced by this amount.

Therefore, $200 billion will still be the incremental amount to the GDP

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
