Answers are given in the Explanation.
Explanation:
A closed economy does not trade with the rest of the world, and, thus, its net exports are zero. Therefore, in this case, GDP is the sum of consumption, Investment, and Government purchases. To find the missing value of Investment, the national income accounting identity can be rearranged as follows:
GDP = C+I+G
I = GDP - C - G
= 780 - 300 -200
=$280
National Saving is the total income in the economy that is left over after paying for consumption and government purchases. In a closed economy, subtracting consumption and government purchases from GDP also yields investment spending, so national Saving equals Investment:
National Saving (S) = GDP−C−G
=780 - 300 -200
=$280 = Investment (I)
Private Saving is the income that remains after households pay taxes and make consumption expenditures:
Private Saving = GDP−C−T
=780 - 300 -260
=$220
Public Saving is the amount of tax revenue that the government has left over after paying for its spending:
Public Saving = T−G =260 - 200
= $60 million
Based on your calculations, the government is running a budget surplus.
When a government spends less than it collects in tax revenues, it runs a government budget surplus. Public Saving is positive in the case of a budget surplus.
The investment is $280 million.
The private saving is $220 million.
The public saving is $60 million.
The government is running a budget surplus.
Calculation of the investment, private saving, public saving:
Since Y = $780 million
We know that
I = Y-C-G
I = $(780- 300 -200) million
I = $ 280 million
Now
National saving = I = $280 million
Private saving = Y-T-C
= $(780- 260- 300) million
= $220 million
And,
Public saving = T -G
= $(260-200) million
= $ 60 million
The government is running a budget surplus since public saving is positive.
