Consider the following data for a closed​ economy: Y​ = ​$12 trillion C​ = ​$8 trillion G​ = ​$2 trillion Spublic​ = ​$negative 0.50 trillion T​ = ​$2 trillion Now suppose that government purchases increase from ​$2 trillion to ​$2.50 trillion but the values of Y and C are unchanged. What must happen to the values of S and​ I? A. S and I increase by ​$0.50 trillion. B. S and I drop by ​$0.50 trillion. Your answer is correct.C. S drops by ​$0.50 trillion and I increases by ​$0.50 trillion. D. S increases by ​$0.50 trillion and I drops by ​$0.50 trillion.

Answer:

B. S and I drop by ​$0.50 trillion.

Explanation:

In a closed economy we got the following identity

Y = C + I + G

The income is equal to the amount consumed, the amount invested and the goverment spending

12 = 8 + I + 2

I = 2

The investment is equal to the savings of the economy in this case as government and taxes are equal, the public runs at equilibrium

While private sector:

Y - C - T = private savings

12 - 8 - 2 = 2 Private saving

If Government increase government spending by 0.50

The government will run into a deficit making savings decrease as will borrow from the private sector.

This makes the investment decrease as well as savings for the economy as a whole.
