a. Private saving: $2 trillion. b. Public saving: $0 trillion. c. Government purchases: $3 trillion. d. The government budget balance is $4 trillion, indicating a government surplus.
To calculate private saving
, public saving
, and the government budget balance, we can use the following equations:

Government Budget Balance = T - G
Now, let's substitute the given values into these equations:
Given:
Y = $12 trillion
C = $6 trillion
I = $3 trillion
TR = $1 trillion
T = $4 trillion
![\[ S_{\text{private}} = 12 - 6 - 4 = $2 \text{ trillion} \]S_{\text{public}} = 4 - (I + TR) = 4 - (3 + 1) = $0 \text{ trillion} \] \text{Government Budget Balance} = T - G = 4 - 0 = $4 \text{ trillion} \]](https://img.qammunity.org/2024/formulas/business/college/uzam69e0gkzrwv7iun3ujyv35kj6f2k40f.png)
Now, let's answer each part of the question:
a. Private saving: $2 trillion.
b. Public saving: $0 trillion.
c. Government purchases: $3 trillion. (Given that G = Y - C - I)
d. The government budget balance is $4 trillion, and as a result, the government budget is in surplus.
The complete question is:
Consider the following data for a closed economy:
Y = $12 trillion
C = $6 trillion
1 = $3 trillion
TR = $1 trillion
T = $4 trillion
Use the data to calculate the following. (Enter your responses as integers.)
a. Private saving: $ ____ trillion.
b. Public saving: $ ____ trillion.
c. Government purchases: $ ____ trillion.
d. The government budget balance is $ ____ trillion and as a result, the government budget is in
